Answer 1

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

Answer 2

Slightly less effort would be to download the NotificationCompat2 JAR library and point to that instead.

Answer 3

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.

Answer 4

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();
  }
}

Answer 5

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 ;)

Answer 6

@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();
  }
}
