问题
I am making an dictionary for android phones and tablets. I have committed the file on my developer account, and i works like a charm on phone. When i am trying to run the exactly same code on my samsung galaxy tab 10.1, it is stuck.
if (!expansionFilesDelivered()) {
try {
Intent launchIntent = SampleDownloaderActivity.this.getIntent();
Intent intentToLaunchThisActivityFromNotification = new Intent(SampleDownloaderActivity.this, SampleDownloaderActivity.this.getClass());
intentToLaunchThisActivityFromNotification.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
intentToLaunchThisActivityFromNotification.setAction(launchIntent.getAction());
if (launchIntent.getCategories() != null) {
for (String category : launchIntent.getCategories()) {
intentToLaunchThisActivityFromNotification.addCategory(category);
}
}
// Build PendingIntent used to open this activity from
// Notification
PendingIntent pendingIntent = PendingIntent.getActivity(SampleDownloaderActivity.this, 0, intentToLaunchThisActivityFromNotification, PendingIntent.FLAG_UPDATE_CURRENT);
// Request to start the download
NotificationManager nm = (NotificationManager) getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
int startResult = DownloaderClientMarshaller.startDownloadServiceIfRequired(this, pendingIntent, SampleDownloaderService.class);
if (startResult != DownloaderClientMarshaller.NO_DOWNLOAD_REQUIRED) {
// The DownloaderService has started downloading the files,
// show progress
initializeDownloadUI();
return;
} // otherwise, download not needed so we fall through to
// starting the movie
} catch (NameNotFoundException e) {
Log.e(LOG_TAG, "Cannot find own package! MAYDAY!");
e.printStackTrace();
}
}
It comes with this exception :

please help me, thanks

i have the same problem . i have a lead , though:
if you search for "setProgress" , you can see that it exists on the file "V11CustomNotification" , which is intended (i think ) for API11+ , which includes honeycomb for the tablets.
"setProgress" is only available for API14+ , so you get an exception.
now , the question is , how to fix it ...
there are 2 ways: 1.check if the method exists on "CustomNotificationFactory" , and if not , return the V3CustomNotification instance.
2.change the code that calls the "setProgress" method , so that it will work for API11..13 (including).
in any case , please tell us what you've done (exactly) , so that we could all benefit from it.
i've chosen fix #1 , since it's easier and i didn't succeed with #2 (i tried) : edit the file , and use there the next code:
static public DownloadNotification.ICustomNotification createCustomNotification()
{
try
{
final Class<?> notificationBuilderClass = Class.forName("android.app.Notification$Builder");
notificationBuilderClass.getDeclaredMethod("setProgress", new Class[] {Integer.TYPE, Integer.TYPE, Boolean.TYPE});
return new V11CustomNotification();
}
catch (final Exception e)
{
return new V3CustomNotification();
}
}
回答2:
I simply added a few lines of code to the com.google.android.vending.expansion.downloader.impl .V11CustomNotification class:
public class V11CustomNotification implements DownloadNotification.ICustomNotification {
// ...
boolean hasSetProgressFunction = false; // Added
boolean hasCheckedForSetProgressFunction = false; // Added
public void CheckForFunction() { // Added
try {
final Class<?> notificationBuilderClass = Class.forName("android.app.Notification$Builder");
notificationBuilderClass.getDeclaredMethod("setProgress", new Class[] {Integer.TYPE, Integer.TYPE, Boolean.TYPE});
this.hasSetProgressFunction = true;
} catch (final Exception e) {
this.hasSetProgressFunction = false;
}
this.hasCheckedForSetProgressFunction = true;
}
// ...
@Override
public Notification updateNotification(Context c) {
if(!this.hasCheckedForSetProgressFunction) { // Added
this.CheckForFunction(); // Added
} // Added
// ...
builder.setContentTitle(mTitle);
if(this.hasSetProgressFunction) { // Added
if ( mTotalKB > 0 && -1 != mCurrentKB ) {
builder.setProgress((int)(mTotalKB>>8), (int)(mCurrentKB>>8), false);
} else {
builder.setProgress(0,0,true);
}
} // Added
// ...
}
}
It's the answer from "android developer" used in a different way ;)

I had problem with notifications on tablet (Galaxy Tab with Android 3). NotificationCompat utility with android-support-v4.jar revision 10 throws this error. It is probably bug in support library.
java.lang.NoSuchMethodError: android.app.Notification$Builder.setProgress
at android.support.v4.app.NotificationCompatIceCreamSandwich.add(NotificationCompatIceCreamSandwich.java:31)
at android.support.v4.app.NotificationCompat$NotificationCompatImplIceCreamSandwich.build(NotificationCompat.java:104)
at android.support.v4.app.NotificationCompat$Builder.build(NotificationCompat.java:558)
I solved this problem using this repaired support library rev. 10: http://code.google.com/p/yuku-android-util/source/browse/ActionBarSherlock4/libs/android-support-v4.jar. With this JAR, it works fine for me.
Thanks to yukuku: http://code.google.com/p/android/issues/detail?id=36359
EDIT: New Support Library, revision 11 (November 2012) fix this problem.

I have solved the problem. I tok this code and copied instead of the code there where in CustomNotificationFactory
static public DownloadNotification.ICustomNotification createCustomNotification()
{
try
{
final Class<?> notificationBuilderClass = Class.forName("android.app.Notification$Builder");
notificationBuilderClass.getDeclaredMethod("setProgress", new Class[] {Integer.TYPE, Integer.TYPE, Boolean.TYPE});
return new V11CustomNotification();
}
catch (final Exception e)
{
return new V3CustomNotification();
}
}
I works perfect :D thanks a lot :D
回答5:
@Fuglsang and @android developer's answer works for me, it's perfect...
static public DownloadNotification.ICustomNotification createCustomNotification()
{
try
{
final Class<?> notificationBuilderClass = Class.forName("android.app.Notification$Builder");
notificationBuilderClass.getDeclaredMethod("setProgress", new Class[] {Integer.TYPE, Integer.TYPE, Boolean.TYPE});
return new V11CustomNotification();
}
catch (final Exception e)
{
return new V3CustomNotification();
}
}
回答6:
I see the same failure on a Toshiba Thrive. The answer from "android developer" works. Basically this means that the download_library was not tested on a V11 device.
回答7:
Slightly less effort would be to download the NotificationCompat2 JAR library and point to that instead.
