How can I specify the scheme specific part in a data tag for an intent-filter?

Question

I want to set up a BroadcastReceiver to handle PACKAGE_REPLACED, but I only want to be notified when my package is replaced. It works fine if I specify a data tag with scheme="package" but then I get notified when any application is reinstalled or upgraded. I can't figure out how I'm supposed to specify the package name which is in the scheme specific part -- that is, when my BroadcastReceiver gets the intent in onRecieve(), if I do intent.getData().getSchemeSpecificPart(), that's the package name, but is there any way I can filter for only that in my intent-filter?

Answer 1

Easiest would be to accept any broadcast intents with the package scheme as you say, but do the filtering based on the Intent extras that are sent with the PACKAGE_* actions.

If the package name in the Intent doesn't match yours, just ignore it.

Answer 2

As used in Google Search App:

<intent-filter>
  <action android:name="android.intent.action.PACKAGE_REPLACED" /> 
  <data android:scheme="package" android:path="com.google.android.googlequicksearchbox" /> 
</intent-filter>

But according to my rough test, this can still catch any updated package, which renders the "android:path" part actually useless.

For Android 3.1+, you can use this new action to respond only when your package updated:

<intent-filter>
  <action android:name="android.intent.action.MY_PACKAGE_REPLACED" /> 
</intent-filter>

If you have to support back to Android 2.x, a better practice is to declare 2 separate receivers for PACKAGE_REPLACED and MY_PACKAGE_REPLACED. Then upon first run, check the runtime Android version and disable the old one if version is 3.1+.
