我的菜单有问题。 这项工作之前，但现在当我点击AVD菜单时，设备将强制关闭。 在我的应用程序中一些活动工程菜单但有些人不行。例如，这项活动不起作用，我可以找到错误。 这是我在java上的代码：
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.alert_setting, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
switch (item.getItemId()){
case R.id.mnuAlertExit:
finish();
System.exit(0);
break;
case R.id.mnuAlertMainMenu:
startActivity(new Intent(AlertSettingActivity.this,MainActivity.class));
finish();
break;
case R.id.mnuAlertSettings:
startActivity(new Intent(AlertSettingActivity.this,SlaveCommand.class));
finish();
break;
}
这是我的菜单代码：
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.gpsportalsms.AlertSettingActivity" >

<item android:id="@+id/mnuAlertContact" android:title="ارسال نظرات پیشنهادات"> </item>
<item android:id="@+id/mnuAlertExit" android:title="خروج"></item>
</group>
</menu>
这是我的logcat
