这里是我在 AlarmReceiver.java

Here is the code which I am using in AlarmReceiver.java

public void setRepeatAlarm(Context context, Calendar calendar, int ID, long RepeatTime) {
        mAlarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

        // Put Reminder ID in Intent Extra
        Intent intent = new Intent(context, AlarmReceiver.class);
        intent.putExtra(ReminderEditActivity.EXTRA_REMINDER_ID, Integer.toString(ID));
        mPendingIntent = PendingIntent.getBroadcast(context, ID, intent, PendingIntent.FLAG_CANCEL_CURRENT);

        // Calculate notification timein
        Calendar c = Calendar.getInstance();
        long currentTime = c.getTimeInMillis();
        long diffTime = calendar.getTimeInMillis() - currentTime;

        while(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 rebooted
        ComponentName receiver = new ComponentName(context, BootReceiver.class);
        PackageManager pm = context.getPackageManager();
        pm.setComponentEnabledSetting(receiver,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP);
    }

如何解决此问题？

推荐答案

我认为对信号3作出反应是ANR的症状。应用程序在崩溃之前是否挂起？

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.

您确定 RepeatTime 始终大于0特别不= 0）？

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

如下：

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

不应该显示多行。

更新：

您应确保警报在未来或重复时间大于0

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 consistents

        while(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 rebooted
        ComponentName receiver = new ComponentName(context, BootReceiver.class);
        PackageManager pm = context.getPackageManager();
        pm.setComponentEnabledSetting(receiver,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                PackageManager.DONT_KILL_APP);

    }
