android widget stop update the code after few hours?
I am working on a battery widget, so when ever Intent.ACTION_BATTERY_CHANGED occurs it is recived by widget onRecive method from where I can get its data now the problem is this, that this whole procedure goes find fine but when time passes means u can say widget gets live round about can say 4 to 5 hours and Widget stops update, at the moment i am using textveiw to show the data of battery but after some hours widget stops updating data in the textVeiw here is the code
here is the update method of widget @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
context.getApplicationContext().registerReceiver(this,
new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
ComponentName cn =
new ComponentName(context, BatteryInfoActivity.class);
appWidgetManager.updateAppWidget(cn, this.views);
}
here is the on onRecive method
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_BATTERY_CHANGED)) {
//Integer level = intent.getIntExtra("level", -1);
String mgs = "--";
//String BatterInfo = "Level"+ intent.getIntExtra("level", -1)+ "/" + intent.getIntExtra("scale", -1);
Integer level = intent.getIntExtra("level", -1);
Integer scale = intent.getIntExtra("scale", -1);
Integer temp = intent.getIntExtra("temperature",-1);
Integer voltage = intent.getIntExtra("voltage", -1);
Integer health = intent.getIntExtra("health", -1);
boolean present = intent.getBooleanExtra("present", false);
Integer plugged = intent.getIntExtra("plugged", -1);
String technology = intent.getStringExtra("technology");
Integer status = intent.getIntExtra("status",-1);
mgs = mgs + " Technology " + technology + "--";
mgs = mgs + "Battery is Present " + present+"--";
mgs = mgs + " level "+ level + "/" + scale + "--";
mgs = mgs + "tempuratue" + temp + "--";
mgs = mgs + "voltage"+ voltage + "--";
this.views.setTextViewText(R.id.textView1, mgs);
ComponentName cn =
new ComponentName(context, BatteryInfoActivity.class);
AppWidgetManager.getInstance(context).updateAppWidget(cn, this.views);
}
super.onReceive(context, intent);
}
You cannot register a BroadcastReceiver from another BroadcastReceiver this way. You cannot do much of anything in onReceive() that would live past the end of onReceive() itself.
