Я пытаюсь получить информацию о батарее из своего приложения в соответствии с рекомендациями http://developer.android.com/training/monitoring-device-state/battery-monitoring.html
Это метод, с помощью которого можно проверить уровень заряда батареи:
public void sendBatteryInfoMessage(){
IntentFilter iFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = c.registerReceiver(null, iFilter);
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING || status == BatteryManager.BATTERY_STATUS_FULL;
int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
boolean isUsbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
boolean isAcCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
int batteryLevel = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
float batteryPct = batteryLevel / (float) scale;
}
c инициализируется как Context объект ранее в классе.
Это сообщение об ошибке, которое я получаю

Мне нужно знать значение IntentReceiver components are not allowed to register to receive intents и как это сделать.
Спасибо
Вместо:
c.registerReceiver(null, iFilter)
использование:
c.getApplicationContext().registerReceiver(null, iFilter)
Context, который передается в onReceive(), блокируется при вызове registerReceiver(), даже с null BroadcastReceiver.
