How to find the package name which has been uninstalled when using Intent.ACTION_PACKAGE_REMOVED
The package names are in the Intent you got from BroadcasReceiver, use the "getData()" function, there is the ComponentMame of the installed/uninstalled package.

I have an application which is keeping a log of internally developed applications installed on the device. Upon installation a broadcast receiver for Intent.PACKAGE_ADDED is invoked and records the package name using the following code:
public class NewInstallReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle b = intent.getExtras(); int uid = b.getInt(Intent.EXTRA_UID); String[] packages = context.getPackageManager().getPackagesForUid(uid); ApplicationService appService = new ApplicationService(context); appService.ApplicationInstalled(packages); } }
The problem I'm facing is when using a broadcast receiver for Intent.PACKAGE_REMOVED, all reference to the package via the unique Id (UID) comes back with null information (As you would expect, given its already been uninstalled). I have a temporary solution for the meantime, but its not very elegant, and for the next version I would like to have cleaner code. An example of how the code should work:
public class RemoveApplicationReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Bundle b = intent.getExtras(); int uid = b.getInt(Intent.EXTRA_UID); String[] packages = context.getPackageManager().getPackagesForUid(uid); ApplicationService appService = new ApplicationService(context); appService.ApplicationRemoved(packages); } }
So to recap, the question is:
How, after a program has been removed, can I reference the package name in a broadcast receiver for Intent.PACKAGE_REMOVED.

Martin over 12 yearsWorked great... simply used getData().getSchemeSpecificPart(). Thanks

gonzobrains about 11 yearsWhen I print out intent.toString() I can see the package name, but when I use intent.getData().getSchemeSpecificPart() I get an empty string. What am I doing wrong?

Anubian Noob almost 9 years@gonzobrains You probably didn't set the scheme? In the manifest, it should look like this:
<data android:scheme="package" />
