我的问题出现在MainActivity应用程序在闹钟响起时崩溃，我还有另一项活动，其中闹钟效果很好。另一个奇怪的事情是整个应用程序包括MainActivity只能在模拟器上正常工作但在设备上它停止响应，Logcat只显示java.lang.nosuchmethod错误。调试停止光标：
mainAmStart.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), mainPIStart);
在android v2.3.3和4.1.2以及4.4.2的模拟器上测试过。 我已经挣扎了好几个小时并且经历了所有谷歌和stackoverflow但没有成功我知道周围有相关的问题，但我的情况似乎安静不同所以决定问一个问题
以下是MainActivity.class，它完全适用于模拟器但在设备上崩溃
mainAmStart = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
mainAmStop = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent mainIntentStart = new Intent(context, MainStartService.class);
Intent mainIntentStop = new Intent(context, MainStopService.class);
mainPIStart = PendingIntent.getService(context, 1001,mainIntentStart, 0);
mainPIStop = PendingIntent.getService(context, 1002, mainIntentStop, 0);
mainAmStart.setExact(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), mainPIStart);
mainAmStop.setExact(AlarmManager.RTC_WAKEUP,
MainActivity.endTimeLong, mainPIStop);
prefs.edit().putBoolean("mainAmStart", true).commit();
prefs.edit().putBoolean("mainAmStop", true).commit();
以下是FajraActivity.class，它在模拟器和设备上都很有用
fajraAMStart = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
fajraAMStop = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intentStart = new Intent(context, FajraStartService.class);
Intent intentStop = new Intent(context, FajraStopService.class);
fajraPIStart = PendingIntent.getService(context, 11, intentStart, 0);
fajraPIStop = PendingIntent.getService(context, 12, intentStop, 0);
fajraAMStart.setRepeating(AlarmManager.RTC_WAKEUP,
startTimeLong, AlarmManager.INTERVAL_DAY, fajraPIStart);
fajraAMStop.setRepeating(AlarmManager.RTC_WAKEUP,
endTimeLong, AlarmManager.INTERVAL_DAY, fajraPIStop);
prefs.edit().putBoolean("fajraAMStart", true).commit();
prefs.edit().putBoolean("fajraAMStop", true).commit();
logcat的
