I am having an application where user can register and unregister receiver from Settings to enable and disable service of app.
I have taken a toggle button to let user control the app service.I registered a receiver on its on state and unregistered the same on its off state.
It works fine when I enable the app service by making toggle button in on state,it successfully registered the receiver and gives me toast.
But when I try to click again on toggle button making it in off state,it gives me exception on line unregisterReceiver(..).
Here is the code:
...
onoff.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
BroadcastReceiver b=new SmsReactor();
if(onoff.isChecked())
{
try
{
IntentFilter iFilter=new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
iFilter.setPriority(100);
registerReceiver(b,iFilter);
Toast.makeText(context,"Service Started!",Toast.LENGTH_SHORT).show();
}
catch (Exception e) {
onoff.setChecked(false);
Toast.makeText(context,"Sorry,Couldn't start the service!Try again.",Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
else
{
try
{
unregisterReceiver(b); // here it gives me exception
Toast.makeText(context,"Service Stopped!",Toast.LENGTH_SHORT).show();
}
catch (Exception e){
onoff.setChecked(true);
Toast.makeText(context,"Sorry,Couldn't stop the service!Try again.",Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
});
...
And the logcat:
