Question

I’ve been searching for this and only find really messed up things.
Isn’t there a easy way to show the battery level like 21% on a toast or Textview?
Or how can i achieve this?

Answer 1

if you mean changing the battery status on the emulator do the following. Connect to the emulator via telnet and change the status and capacity

> telnet localhost 5554
Android Console: type 'help' for a list of commands
OK
power ac off
OK
power discharging
OK
power capacity 21
OK
exit

Ahh, well you can do what it says on the page Ted mentioned, and then use a handler to show a toast. This is the code you need to add to your activity.

private Handler handler = new Handler;

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(final Context context, Intent intent) {
        int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);
        int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, 100);
        Log.i(TAG, "level: " + level + "; scale: " + scale);
        int percent = (level*100)/scale;

        final String text = String.valueOf(percent) + "%";
        handler.post( new Runnable() {

            public void run() {
                Toast.makeText(context, text, Toast.LENGTH_SHORT).show();
            }
        });

    }
};
