It Is Not Under Singleton Mode, U Can't Use It

In my Reminder app, If I select time which just passed away, then app not working, getting following error: Log D/ANRAppManager: !!! It is not under singleton mode, U can't use it.

Solution 1:

I think that reacting to signal 3 is a symptom of an ANR. Does the application hang before crashing ? If so, it may be because the loops never ends.

Are you sure that RepeatTime is always > 0 (and specially not = 0) ?

Something like :

while(diffTime < 0) {
         Log.d("SOME_TAG", "set diffTime to " + diffTime);
         diffTime += RepeatTime; // at this line getting error
    }

should not display more than a few lines.

Update :

You should ensure that either the alarm is in the future or the repeat time is greater than 0.

if (diffTime > 0 || RepeatTime > 0) {

        // set the alarm only if the parameters are consistentswhile(diffTime < 0) {
             diffTime += RepeatTime; // at this line getting error
        }

        // Start alarm using initial notification time and repeat interval time
        mAlarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME,
                SystemClock.elapsedRealtime() + diffTime,
                RepeatTime , mPendingIntent);

        // Restart alarm if device is rebootedComponentNamereceiver=newComponentName(context, BootReceiver.class);
        PackageManagerpm= context.getPackageManager();
        pm.setComponentEnabledSetting(receiver,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP);

    }
