I wrote a widget for Android and I’m trying to get the battery level.
I’ve tried using
Intent batteryIntent = context.registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
but I get the error:
“IntentReceiver components are not allowed to register to receive intents”
Why? the ACTION_BATTERY_CHANGED is a sticky intent and I don’t register a receiver (null in the first parameter).
Any workaround?
Thanks.
hackbod gave the solution at the comments:
” use getApplicationContext().registerReciever() “
