问题：
“不幸的'app'已停止”错误[重复]
彭梓
这个想法是在警报开始时启动一个游戏。我已经在下面展示了manifest.xml。如果我犯了错误，请纠正我。因为我是Android的新手，所以我不太懂。PS：我已经搜索了其他类似的问题，并更正了很多其他错误，但问题依然存在。
这是我从一个教程（AndroidTimeActivity）得到的警报代码：
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(
"\n\n***\n"
+ "Alarm is set@ " + targetCal.getTime() + "\n"
+ "***\n");
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：
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);
}
}
这里是Manager类，当警报接收器接收到意图时，我要调用它：
public class Manager extends Activity {
private static int ROW_COUNT = -1;
private static int COL_COUNT = -1;
private Context context;
private Drawable backImage;
private int [] [] cards;
private List<Drawable> images;
private Card firstCard;

private ButtonListener buttonListener;
private static Object lock = new Object();
int turns;
private TableLayout mainTable;

super.onCreate(savedInstanceState);

loadImages();
setContentView(R.layout.main);

s.setAdapter(adapter);
s.setOnItemSelectedListener(new OnItemSelectedListener(){
public void onItemSelected(
android.widget.AdapterView<?> arg0,

public void checkCards(){

firstCard.button.setVisibility(View.INVISIBLE);
seconedCard.button.setVisibility(View.INVISIBLE);
}
else {
seconedCard.button.setBackgroundDrawable(backImage);
firstCard.button.setBackgroundDrawable(backImage);
}
firstCard=null;
seconedCard=null;
}
}
}
这是我的清单，我确实为Manager类创建了一个activity，但是“AndroidTime已经停止”错误仍然存在。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.exercise.AndroidTime"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name="com.exercise.AndroidTime.AndroidTimeActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".AlarmReceiver" android:process=":remote" />
<activity android:name="com.exercise.AndroidTime.Manager"></activity>
</application>
</manifest>
谢谢你的帮助。

我的申请已经停止了。项目将场景转换为作业列表的主要应用，但是，作业列表转换为练习列表，我得到了这些“不幸的应用程序已经停止了”。这是我的类。我也是致命的，除了在logcat。 ApplicationMain.java joblist.java ExpresseList.java AndroidManifest.xml

我对Android编程完全陌生。我正在制作的第一个应用程序遇到了一些问题。每次我运行应用程序时，我的手机（我正在使用它来测试和调试我的应用程序）上会弹出一条消息说“不幸的是，MyNewApp3已停止”。这个错误甚至无法打开我的应用程序。我如何解决这个问题？ 这是我的代码： 我的LogCat输出（这是我在看到别人建议别人放置LogCat输出后发布的；我不知道它是用来做什么的）： 01-12 11:4
