关于java：“不幸’app’已停止”错误

“Unfortunately 'app' has stopped” error

本问题已经有最佳答案，请猛点这里访问。

我们的想法是在警报响起时启动一个游戏。我已经显示了下面的manifest.xml。如果我犯了错误，请纠正我。因为我刚接触到Android，所以我没办法搞清楚。附言：我已经搜索了其他类似的问题并纠正了许多其他错误，但问题仍然存在。

这是我从教程中获得的警报代码(AndroidTimeActivity)：

public class AndroidTimeActivity extends Activity {

TimePicker myTimePicker;
Button buttonstartSetDialog;
TextView textAlarmPrompt;

TimePickerDialog timePickerDialog;

final static int RQS_1 = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

textAlarmPrompt = (TextView)findViewById(R.id.alarmprompt);

buttonstartSetDialog = (Button)findViewById(R.id.startSetDialog);
buttonstartSetDialog.setOnClickListener(new OnClickListener(){

public void onClick(View v) {
textAlarmPrompt.setText("");
openTimePickerDialog(false);

}});

}

private void openTimePickerDialog(boolean is24r){
Calendar calendar = Calendar.getInstance();

timePickerDialog = new TimePickerDialog(
AndroidTimeActivity.this,
onTimeSetListener,
calendar.get(Calendar.HOUR_OF_DAY),
calendar.get(Calendar.MINUTE),
is24r);
timePickerDialog.setTitle("Set Alarm Time");

timePickerDialog.show();

}

OnTimeSetListener onTimeSetListener= new OnTimeSetListener(){

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

Calendar calNow = Calendar.getInstance();
Calendar calSet = (Calendar) calNow.clone();

calSet.set(Calendar.HOUR_OF_DAY, hourOfDay);
calSet.set(Calendar.MINUTE, minute);
calSet.set(Calendar.SECOND, 0);
calSet.set(Calendar.MILLISECOND, 0);

if(calSet.compareTo(calNow) <= 0){
//Today Set time passed, count to tomorrow
calSet.add(Calendar.DATE, 1);
}

setAlarm(calSet);
}};

private void setAlarm(Calendar targetCal){

textAlarmPrompt.setText(
"

***
"
+"Alarm is set@" + targetCal.getTime() +"
"
+"***
");

Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(),RQS_1,
intent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
pendingIntent);

}

}

这是AlarmReceiver类：

7
8
9
10
11

public class AlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent arg1) {
Intent activityIntent = new Intent(context, Manager.class);
activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(activityIntent);

}

}

下面是当报警接收器接收到意图时我要调用的管理器类：
