intent-filter with android:priority setting

Question

I test the intent-filter android:priority="0" and intent-filter android:priority="20" by android.intent.category.HOME. I list the information below,

    <activity android:name=".TestHomeActivity"
              android:label="@string/app_name">
        <intent-filter android:priority="0">
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.LAUNCHER" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

When finishing system booting, it always pops up a dialog (ResolveActiivty) for choose preferred activity for this intent...

Can anyone can help this? is it error usage for android:priority?

Thanks!

Answer 1

I haven't actually seen android:priority being taken into account when the system is resolving intents. I just tried setting a priority on an intent-filter that I use, but the system still gave me the resolution popup dialog, no matter what value I set my intent-filter's priority to.

I guess you'll just have to select the home screen activity you want to use (i.e. yours) and select the "Use by default..." checkbox.

android:priority is only used on OrderedBroadcast intents, not the order of resolution for non-ordered broadcasts. Users select the default activity for a given action, which is why the dialog pops up. So, yes, you are using priority incorrectly.
