Usage

From source file:org.digitalcampus.oppia.utils.MetaDataUtils.java

private float getBatteryLevel() {
    Intent batteryIntent = ctx.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    int level = batteryIntent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
    int scale = batteryIntent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);

    // Error checking that probably isn't needed but I added just in case.
    if (level == -1 || scale == -1) {
        return 50.0f;
    }//from  www  . jav  a  2 s. com

    return ((float) level / (float) scale) * 100.0f;
