I am having the exact same problem as this post: Battery broadcast receiver doesn't work. But it seems no one has answered that question.
Here is my BroadcastReceiver:
public class BatteryLevelReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
Log.v("plugg", "plug change fired");
Toast.makeText(context, " plug change fired", Toast.LENGTH_LONG).show();
}
And here is my AndroidManifest.xml:
<receiver android:name=".ReceversAndServices.BatteryLevelReceiver">
<intent-filter android:priority="900">
<action android:name="android.intent.action.BATTERY_LOW" />
</intent-filter>
</receiver>
<receiver android:name=".ReceversAndServices.BatteryLevelReceiver">
<intent-filter android:priority="900">
<action android:name="android.intent.action.BATTERY_CHANGED" />
</intent-filter>
</receiver>
I have also added this line to the manifest:
<uses-permission android:name="android.permission.BATTERY_STATS"/>
But still no success!
I would really appreciate if someone could advise me what I am doing wrong.
From the documentation for ACTION_BATTERY_CHANGED:
You can not receive this through components declared in manifests, only by explicitly registering for it with Context.registerReceiver(). See ACTION_BATTERY_LOW, ACTION_BATTERY_OKAY, ACTION_POWER_CONNECTED, and ACTION_POWER_DISCONNECTED for distinct battery-related broadcasts that are sent and can be received through manifest receivers.
There you have it: you must explicitly register for it from your Java code.
