Android12之am启动music app

1.增加图标显示(因为android12原生Muisc应用禁掉图标显示)
# emacs packages/apps/Music/AndroidManifest.xml
<activity android:name="com.android.music.MusicPicker"
					android:label="@string/music_picker_title" android:exported="true" >


+<intent-filter>
+	<action android:name="android.intent.action.MAIN" />
+	<category android:name="android.intent.category.LAUNCHER" />
+</intent-filter>

<intent-filter>
	<action android:name="android.intent.action.GET_CONTENT" />
	<category android:name="android.intent.category.DEFAULT" />
	<category android:name="android.intent.category.OPENABLE" />
	<data android:mimeType="audio/*"/>
	<data android:mimeType="application/ogg"/>
	<data android:mimeType="application/x-ogg"/>
</intent-filter>



2.启动Music
# adb shell am start -n com.android.music/.MusicPicker

3.查看Music当前的栈中显示（反推可以用此方式）
# adb shell dumpsys window|grep -i music --color
