interacting with a +document. This class is responsible for creating the view hierarchy and the +menus. + + +Main view classes +~~~~~~~~~~~~~~~~~ + +ReaderView +~~~~~~~~~~ +MuPDF uses Android's standard Adapter/AdapterView paradigm, where a subclass of +BaseAdapter supplies multiple views that have their motion on screen +choreographed by a subclass of AdapterView. There are several standard +AdapterView subclasses, but none support zooming into a specific subview and +then panning within it, so MuPDF has its own AdapterView subclass, namely +ReaderView. The class is intended to be general purpose and usable within any +document-viewing application. During page viewing, ReaderView handles all touch +events, recognises gestures and positions the displayed document pages +accordingly. ReaderView needs to handle positioning slightly differently +depending on whether MuPDF is reflowing text or not, and so it has two slightly +different modes of operation. + +MuPDFReaderView +~~~~~~~~~~~~~~~ +MuPDFReaderView subclasses ReaderView, so as to provide some of the +page-positioning behaviour that is specific to MuPDF. It overrides some of the +gesture recognition methods of ReaderView, so that it can perform special +handling of (e.g.) tapping on the side of the screen for page progression, and +tapping on links or form fields. It also handles the disabling of scrolling +during text-selection and annotation-drawing, and it performs the setup +operations needed by the individual page views as each newly appears. + +MuPDFView +~~~~~~~~~ +Document viewing uses different View subclasses to display the individual pages +depending on whether reflowing text or displaying pages unaltered. MuPDFView is +the common interface to the two view subclasses. + +PageView +~~~~~~~~ +PageView is the main View class used for non-reflow display of a page. Like +ReaderView, it is intended to be, as much as is possible, independent of the +specifics of MuPDF and usable in general document display apps. It is a +subclass of ViewGroup because page displays are built from several layers. The +lowest layer is a rendering of the page at a resolution that matches the screen +exactly when maximally zoomed out so that the page fits the screen. As the user +zooms in, this layer maintains a visible appearance of the page, but one that +becomes more blurred as zooming in progresses. A second layer provides a higher +resolution rendering of just the area of the page that is visible on screen, +and at a resolution that matches the screen. As the user pans, this layer is +updated on a background thread, so parts of the blurred layer will temporarily +become visible, but only momentarily later to be replaced by the high-quality +rendering. There is one further layer that is used to draw transparent shapes +for highlighting and the like. + +MuPDFPageView +~~~~~~~~~~~~~ +MuPDFPageView is a subclass of PageView, which handles some of the specifics of +MuPDF's behaviour, such as taps on links and form fields, text selection, and +annotation drawing. It also handles its parent class's bitmap rendering calls. +This is the class used to display pages in non-reflow mode. It implements the +MuPDFView interface. + +MuPDFReflowView +~~~~~~~~~~~~~~~ +This is the class used to display pages in reflow mode. Like MuPDFPageView it +implements the MuPDFView interface. It is a subclass of WebView, and achieves +reflowing by loading an HTML version of the page, which the MuPDF core +constructs. + +MuPDFPageAdapter and MuPDFReflowAdapter +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +As with any AdapterView subclass, ReaderView needs an Adapter subclass to +supply, on demand, the subviews for the pages currently displayed. These are +the two Adapter subclasses, supplying the subviews as MuPDFPageView and +MuPDFReflowView objects respectively. The former is a little more complex than +the latter, since it caches the sizes of the pages corresponding to the views +it supplies. It does so, so that page views, on their second and subsequent +appearances, can take on their correct size immediately. (The determining of +page size is not a completely trivial operation and is performed on a +background thread, as is all interaction with the core MuPDF library). + + +C library wrapper +~~~~~~~~~~~~~~~~~ + +MuPDFCore +~~~~~~~~~ +This class is the interface to the MuPDF C library. It is used to render bitmap +versions of the page for display in the view classes mentioned above. It also +provides for interaction with objects within the page, such as the individual +text objects and annotations. Many of the methods take too long an execution +time to be run on the UI thread, hence they need to be run in the background, +and because even the fast methods have to be synchronised with the slower +methods, (almost) all methods should be called in the background. There are a +few non synchronised ones that have special purposes. + + +Link handling +~~~~~~~~~~~~~ +There are three types of PDF links, each entailing different information and +requiring different handling. There are five classes involved in their +representation. + +LinkInfo is the base class representing any one of the three + +LinkInfoExternal, LinkInfoInternal and LinkInfoRemote are the three subclasses +representing the specific cases. + +LinkInfoVisitor is a class implementing a common Java paradigm which allows +case analysis on the three different types of link, executing different methods +for each. + +BitmapHolder +~~~~~~~~~~~~ +BitmapHolder is the solution to a problem in allocating the Bitmaps to which +rendering is performed by background tasks. Renderings for the purpose of +update have to be passed a Bitmap with the current page state. During frenetic +page flicking a large number of rendering tasks can be queued, each holding +reference to a Bitmap. Rather than pass the Bitmap directly, we pass a +BitmapHolder containing a reference to the Bitmap. When a page view transitions +off screen, the BitmapHolder's reference to the Bitmap can be nulled to release +it. + +SearchTask and SearchTaskResult +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +SearchTask encapsulates the process of searching for a text string within a +document. The class uses an AsyncTask internally to perform the search in the +background and reports the result by calling onTextFound. A SearchTaskResult +object is used to return the result of the search. + +SafeAnimatorInflator +~~~~~~~~~~~~~~~~~~~~ +This class is a simple wrapper around AnimatorInflator. AnimatorInflator +doesn't exist in some of the Android API levels MuPDF supports, and the wrapper +allows for a test of API-level before the point at which the class would be +loaded. + +MuPDFAlert and MuPDFAlertInternal +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +This class represents the information issued by a javascript app.alert call. +MuPDFAlertInternal represents the same information, but with Java enums +replaced by ints, which are easier to return from JNI code. + +TextChar and TextWord +~~~~~~~~~~~~~~~~~~~~~ +TextChar is used when processing the individual characters of the page. Each +TextChar object contains the character and the rectangular area of the page at +which it appears. TextWord is used to gather TextChars into words. + +Annotation +~~~~~~~~~~ +This class represents the type and position on page of a PDF annotation. + +Other activities +~~~~~~~~~~~~~~~~ +The app has three activities other than document-viewing. + +ChoosePDFActivity +~~~~~~~~~~~~~~~~~ +ChoosePDFActivity allows the user to navigate local disc directories and view a +list of loadable files, from which one can be chosen. It derives off +ListActivity, and so displays the files in a standard ListView. ChoosePDFItem +represents the various types of list entry: up-one, directory or file. +ChoosePDFAdapter populates the list view. + +OutlineActivity +~~~~~~~~~~~~~~~ +OutlineActivity displays a PDF document's outline as a list of selectable +section titles. OutlineActivityData represents the current state of the +activity. OutlineItem represents the individual items, and OutlineAdapter +populates the list view. + +PrintDialogActivity +~~~~~~~~~~~~~~~~~~~ +This activity allows the user to print documents via Google Cloud Print. + + +Copied system classes +~~~~~~~~~~~~~~~~~~~~~ +AsyncTask has had improvements made to it since issuing at the lowest android +API level we support, and so we include the improved version as part of the +MuPDF app. We also include Deque and ArrayDeque, which are used my AsyncTask. + diff --git a/platform/android/viewer/Icons.txt b/platform/android/viewer/Icons.txt new file mode 100644 index 00000000..9d0082bf --- /dev/null +++ b/platform/android/viewer/Icons.txt @@ -0,0 +1,2 @@ +The icons are from http://somerandomdude.com/work/iconic/ +They are covered by the CC-BY-SA license: http://creativecommons.org/licenses/by-sa/3.0/us/ diff --git a/platform/android/viewer/Makefile b/platform/android/viewer/Makefile new file mode 100644 index 00000000..9d061919 --- /dev/null +++ b/platform/android/viewer/Makefile @@ -0,0 +1,3 @@ +default: + ndk-build + ant debug diff --git a/platform/android/viewer/ReadMe.txt b/platform/android/viewer/ReadMe.txt new file mode 100644 index 00000000..f1c0c48c --- /dev/null +++ b/platform/android/viewer/ReadMe.txt @@ -0,0 +1,188 @@ +To build/debug android viewer. + +1) Download the android sdk, and install it.

These instructions were written +with NDK r6b (the latest version at the time of writing) in mind, but the +build has now been tweaked to work with r10b. Other versions may give problems. + +It's important that you use the correct NDK for the target platform. If you're +targeting a 32-bit platform (such as "ARM EABI v7a" or "Intel x86 Arm") then +you MUST use the 32-bit target NDK. If you get UnsatisfiedLinkError when +opening a document in MuPDF, then you've tried to use the 64-bit target NDK +with a 32-bit target! + +On windows I unpacked it as: + + C:\android-ndk-r10b + +on Macos an older version unpacked as: + + /Library/android-ndk-r5 + +on Linux as: + + mkdir ~/android-ndk + cd ~/android-ndk + tar jxvf ~/Downloads/android-ndk32-r10b-linux-x86.tar.bz2 + +It is very important that you should unpack it to a directory with no +spaces in the name! (Don't be tempted to put it in C:\Program Files etc) + +Ensure that that directory is also added to your PATH. + +3) On windows, to use the ndk, you *must* be running under cygwin. This means +you need to install Cygwin 1.7 or greater now. + +[ In version r5 of the ndk, when running under cygwin, there were ] +[ bugs to do with the automatic conversion of dependencies from DOS ] +[ format paths to cygwin format paths. The 2 fixes can be found in: ] +[ ] +[ ] +[ ] +[ Use the latest version and there should not be a problem. ] + +4) If the SDK has not popped up a window already, bring up a shell, and run +'android' (or android.bat on cygwin/windows). You should now have a window +with a graphical gui for the sdk. From here you can install the different SDK +components for the different flavours of android. Download them all - +bandwidth and disk space are cheap, right? Make sure you get at least +the API level 11 as this is the current dependency for mupdf. + +5) In new versions of the GUI there is a 'Tools' menu from which you can +select 'Manage AVDs...'. In old versions, go to the Virtual Devices entry +on the right hand side. You need to create yourself an emulator image to +use. Click 'New...' on the right hand side and a window will appear. Fill +in the entries as follows: + + Name: FroyoEm + Target: Android 2.2 - API Level 8 + CPU/ABI: ARM (armeabi) (If this option exists) + SD card: Size: 1024MiB + Skin: Resolution: 480x756 (756 just fits my macbook screen, but 800 may + be 'more standard') + +Click 'Create AVD' (on old versions you may have to wait for a minute or +so while it is prepared. Now you can exit the GUI. + +6) You will need a copy of the JDK installed. See +. When this +installs, ensure that JAVA_HOME is set to point to the installation +directory. + +7) You will need a copy of Apache ANT installed. +See . Ensure that ANT_HOME is set to point to +the top level directory, and that ANT_HOME/bin is on the PATH. + +8) Now we are ready to build mupdf viewer for Android. Check out a copy of MuPDF +(but you've done that already, cos you're reading this, right?). + +9) You will also need a copy of mupdf's thirdparty libraries. If you are +using git, make sure to do a git submodule update --init from the top of +the build tree. Older versions packaged this source code in a .zip-file +(see the source code link on http://mupdf.com/). Unpack the contents of +this into a 'thirdparty' directory created within the mupdf directory +(i.e. at the same level as fitz, pdf, android etc). + +10) Finally, you will need a copy of a 'generated' directory. This is not +currently available to download. + +The normal mupdf build process involves running some code on the host +(the machine on which you are compiling), rather than the target (the +machine/device on which you eventually want to run mupdf). This code +repacks various bits of information (fonts, CMAPs etc) into a more +compact and usable form. + +Unfortunately, the android SDK does not provide a compiler for the host +machine, so we cannot run this step automatically as part of the android +viewer build. You will need to generate it by running a different build, such +as the windows or linux native builds. + +We do not make a snapshot of the generated directory available to +download as the contents of this directory change frequently, and we'd +have to keep multiple versions on the website. We assume that anyone +capable of building for android is capable of doing a normal hosted +build. + +On windows (where you are using cygwin), or on linux/macos, this can be +as simple as running 'make generate' in the top level directory. + +11) Change into mupdf's android/viewer directory. Copy the +android/viewer/local.properties.sample file to be android/viewer/local.properties and +change the sdk path there as appropriate. This should be the only bit of +localisation you need to do. + +12) Change into the android/viewer directory (note, the android/viewer directory, NOT +the android/viewer/jni directory!), and execute (in a Cygwin window on Windows!): + + ndk-build + +This should build the native code portion. + +If this dies with an error in thirdparty/jbig2/os_types.h load this +file into an editor, and change line 43 from: + + #else + +to + + #elif !defined(HAVE_STDINT_H) + +and this should solve the problem. + +13) Then execute: + + ant debug + +or on windows under cygwin: + + ant.bat debug + +This should build the java wrapper. + +14) Now start the emulator by executing: + + emulator -avd FroyoEm + +This will take a while to full start up (be patient). + +15) We now need to give the demo file something to chew on, so let's copy +a file into the SD card image of the emulator (this should only need to be +done once). With the emulator running type: + + adb push ../../MyTests/pdf_reference17.pdf /mnt/sdcard/Download/test.pdf + +(where obviously ../../MyTests/pdf_reference17.pdf is altered for your +machine, and under Windows, should start c:/ even if invoked from cygwin) +(adb lives in /platform-tools if it's not on your path). + +16) With the emulator running (see step 14), execute + + ant debug install + +('ant.bat debug install' on Windows) and that will copy MuPDF into the +emulator where you can run it from the launchpad screen. + +17) To see debug messages from the emulator (including stdout/stderr from +our app), execute: + + adb logcat + +Good luck! diff --git a/platform/android/viewer/build.xml b/platform/android/viewer/build.xml new file mode 100644 index 00000000..7cb2cdf8 ---

AsyncTask enables proper and easy use of the UI thread. This class allows to + * perform background operations and publish results on the UI thread without + * having to manipulate threads and/or handlers.

+ * + *

AsyncTask is designed to be a helper class around {@link Thread} and {@link Handler} + * and does not constitute a generic threading framework. AsyncTasks should ideally be + * used for short operations (a few seconds at the most.) If you need to keep threads + * running for long periods of time, it is highly recommended you use the various APIs + * provided by the java.util.concurrent pacakge such as {@link Executor}, + * {@link ThreadPoolExecutor} and {@link FutureTask}.

+ * + *

An asynchronous task is defined by a computation that runs on a background thread and + * whose result is published on the UI thread. An asynchronous task is defined by 3 generic + * types, called Params, Progress and Result, + * and 4 steps, called onPreExecute, doInBackground, + * onProgressUpdate and onPostExecute.

+ * + *
+ *

Developer Guides

+ *

For more information about using tasks and threads, read the + * Processes and + * Threads developer guide.

+ *
+ * + *

Usage

+ *

AsyncTask must be subclassed to be used. The subclass will override at least + * one method ({@link #doInBackground}), and most often will override a + * second one ({@link #onPostExecute}.)

+ * + *

Here is an example of subclassing:

+ * 
+ * private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
+ *     protected Long doInBackground(URL... urls) {
+ *         int count = urls.length;
+ *         long totalSize = 0;
+ *         for (int i = 0; i < count; i++) {
+ *             totalSize += Downloader.downloadFile(urls[i]);
+ *             publishProgress((int) ((i / (float) count) * 100));
+ *             // Escape early if cancel() is called
+ *             if (isCancelled()) break;
+ *         }
+ *         return totalSize;
+ *     }
+ *
+ *     protected void onProgressUpdate(Integer... progress) {
+ *         setProgressPercent(progress[0]);
+ *     }
+ *
+ *     protected void onPostExecute(Long result) {
+ *         showDialog("Downloaded " + result + " bytes");
+ *     }
+ * }
+ *
+ * + *

Once created, a task is executed very simply:

+ * 
+ * new DownloadFilesTask().execute(url1, url2, url3);
+ *
+ * + *

AsyncTask's generic types

+ *

The three types used by an asynchronous task are the following:

+ *
    + *
  1. Params, the type of the parameters sent to the task upon + * execution.
    2. + *
  2. Progress, the type of the progress units published during + * the background computation.
    3. + *
  3. Result, the type of the result of the background + * computation.
    4. + *
+ *

Not all types are always used by an asynchronous task. To mark a type as unused, + * simply use the type {@link Void}:

+ * 
+ * private class MyTask extends AsyncTask<Void, Void, Void> { ... }
+ *
+ * + *

The 4 steps

+ *

When an asynchronous task is executed, the task goes through 4 steps:

+ *
    + *
  1. {@link #onPreExecute()}, invoked on the UI thread before the task + * is executed. This step is normally used to setup the task, for instance by + * showing a progress bar in the user interface.
    2. + *
  2. {@link #doInBackground}, invoked on the background thread + * immediately after {@link #onPreExecute()} finishes executing. This step is used + * to perform background computation that can take a long time. The parameters + * of the asynchronous task are passed to this step. The result of the computation must + * be returned by this step and will be passed back to the last step. This step + * can also use {@link #publishProgress} to publish one or more units + * of progress. These values are published on the UI thread, in the + * {@link #onProgressUpdate} step.
    3. + *
  3. {@link #onProgressUpdate}, invoked on the UI thread after a + * call to {@link #publishProgress}. The timing of the execution is + * undefined. This method is used to display any form of progress in the user + * interface while the background computation is still executing. For instance, + * it can be used to animate a progress bar or show logs in a text field.
    4. + *
  4. {@link #onPostExecute}, invoked on the UI thread after the background + * computation finishes. The result of the background computation is passed to + * this step as a parameter.
    5. + *
+ * + *

Cancelling a task

+ *

A task can be cancelled at any time by invoking {@link #cancel(boolean)}. Invoking + * this method will cause subsequent calls to {@link #isCancelled()} to return true. + * After invoking this method, {@link #onCancelled(Object)}, instead of + * {@link #onPostExecute(Object)} will be invoked after {@link #doInBackground(Object[])} + * returns. To ensure that a task is cancelled as quickly as possible, you should always + * check the return value of {@link #isCancelled()} periodically from + * {@link #doInBackground(Object[])}, if possible (inside a loop for instance.)

+ * + *

Threading rules

+ *

There are a few threading rules that must be followed for this class to + * work properly:

+ *
    + *
  • The AsyncTask class must be loaded on the UI thread. This is done + * automatically as of {@link android.os.Build.VERSION_CODES#JELLY_BEAN}.
    • + *
  • The task instance must be created on the UI thread.
    • + *
  • {@link #execute} must be invoked on the UI thread.
    • + *
  • Do not call {@link #onPreExecute()}, {@link #onPostExecute}, + * {@link #doInBackground}, {@link #onProgressUpdate} manually.
    • + *
  • The task can be executed only once (an exception will be thrown if + * a second execution is attempted.)
    • + *
+ * + *

Memory observability

+ *

AsyncTask guarantees that all callback calls are synchronized in such a way that the following + * operations are safe without explicit synchronizations.

+ *
    + *
  • Set member fields in the constructor or {@link #onPreExecute}, and refer to them + * in {@link #doInBackground}. + *
  • Set member fields in {@link #doInBackground}, and refer to them in + * {@link #onProgressUpdate} and {@link #onPostExecute}. + *
+ * + *

Order of execution

+ *

When first introduced, AsyncTasks were executed serially on a single background + * thread. Starting with {@link android.os.Build.VERSION_CODES#DONUT}, this was changed + * to a pool of threads allowing multiple tasks to operate in parallel. Starting with + * {@link android.os.Build.VERSION_CODES#HONEYCOMB}, tasks are executed on a single + * thread to avoid common application errors caused by parallel execution.

+ *

If you truly want parallel execution, you can invoke + * {@link #executeOnExecutor(java.util.concurrent.Executor, Object[])} with + * {@link #THREAD_POOL_EXECUTOR}.

This interface defines methods to access the elements at both + * ends of the deque. Methods are provided to insert, remove, and + * examine the element.

This interface extends the {@link Queue} interface. When a deque is + * used as a queue, FIFO (First-In-First-Out) behavior results. Elements are + * added at the end of the deque and removed from the beginning. The methods + * inherited from the Queue interface are precisely equivalent to + * Deque methods as indicated in the following table: + * + *

+ * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + *

{@link java.util.Queue#poll poll()}{@link #pollFirst pollFirst()}
{@link java.util.Queue#element element()}{@link #getFirst getFirst()}
{@link java.util.Queue#peek peek()}{@link #peek peekFirst()}
+ * + *

Deques can also be used as LIFO (Last-In-First-Out) stacks. This + * interface should be used in preference to the legacy {@link Stack} class. + * When a deque is used as a stack, elements are pushed and popped from the + * beginning of the deque. Stack methods are precisely equivalent to + * Deque methods as indicated in the table below: + * + *

+ * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + * + *

{@link #push push(e)}{@link #addFirst addFirst(e)}
{@link #pop pop()}{@link #removeFirst removeFirst()}
{@link #peek peek()}{@link #peekFirst peekFirst()}
+ * + *

Note that the {@link #peek peek} method works equally well when + * a deque is used as a queue or a stack; in either case, elements are + * drawn from the beginning of the deque. + * + *

This interface provides two methods to remove interior + * elements, {@link #removeFirstOccurrence removeFirstOccurrence} and + * {@link #removeLastOccurrence removeLastOccurrence}. + * + *

Unlike the {@link List} interface, this interface does not + * provide support for indexed access to elements. + * + *

While Deque implementations are not strictly required + * to prohibit the insertion of null elements, they are strongly + * encouraged to do so. Users of any Deque implementations + * that do allow null elements are strongly encouraged not to + * take advantage of the ability to insert nulls. This is so because + * null is used as a special return value by various methods + * to indicated that the deque is empty. + * + *
