如何在Android中识别可接听来电的默认应用程序？

Question

I'm simply trying to find out which app is the default app to handle phone calls on my Android test device. Right now, I'm using the following code, this SHOULD work, but always returns null:

Intent phoneApp = new Intent(Intent.ACTION_ANSWER);

ResolveInfo app = mPM.resolveActivity(phoneApp, PackageManager.MATCH_DEFAULT_ONLY);

Any ideas? It seems there is no documentation on this for some reason!

Answer 1

You can use queryIntentActivities() on PackageManager to find out all the applications that could handle that intent, but that's the most you can do.

Unfortunately, there is no way to find out the default application that gets called for that implicit intent (aside from calling that implicit intent yourself, and seeing which application gets launched afterwards)
