我有一个Live Android应用程序,从市场我收到了以下堆栈跟踪,我不知道为什么它发生在应用程序代码中没有发生,但它是由应用程序中的一些或其他事件引起的(假设)
我没有使用Fragments,仍然有FragmentManager的引用.如果任何机构可以对某些隐藏的事实进行一些说明以避免此类问题:
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

有些用户报告,如果他们使用通知栏中的快速操作,他们就会收到一个强制关闭.
我在通知中显示了一个快速操作,它调用了"TestDialog"类.在按下"贪睡"按钮后的TestDialog类中,我将显示SnoozeDialog.
private View.OnClickListener btnSnoozeOnClick() {
return new View.OnClickListener() {
public void onClick(View v) {
showSnoozeDialog();
}
};
}
private void showSnoozeDialog() {
FragmentManager fm = getSupportFragmentManager();
SnoozeDialog snoozeDialog = new SnoozeDialog();
snoozeDialog.show(fm, "snooze_dialog");
}
错误是 *IllegalStateException: Can not perform this action after onSaveInstanceState*.
IllegarStateException被触发的代码行是:
snoozeDialog.show(fm, "snooze_dialog");
该类正在扩展"FragmentActivity",而"SnoozeDialog"类正在扩展"DialogFragment".
以下是错误的完整堆栈跟踪:

at …我的活动使用ACTION_IMAGE_CAPTURE意图调用相机.如果相机活动成功返回,我在onActivityResult回调中设置了一个标志,并根据标志的值我在onResume中启动一个片段,为捕获的图像添加标题.这似乎工作正常.
我只是从"狂野"中得到一个堆栈跟踪抱怨我在调用onSaveInstanceState后尝试提交片段事务.但我正在使用onResume方法进行提交!为什么android会抱怨这个？我的AndroidManifest.xml中设置了android:configChanges ="orientation | keyboardHidden | keyboard | screenSize",因此方向更改不应触发此....
这发生在运行4.0.4的三星Galaxy S3(SGH-i747)上

任何帮助或智慧都表示赞赏.
这是我的PreferenceActivity(我主要活动的内部课程)
public static class TestSettings extends PreferenceActivity implements Preference.OnPreferenceClickListener{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref);
getPreferenceManager().findPreference("key").setOnPreferenceClickListener(this);
}
这是我的onPreferenceClick:
@Override
public boolean onPreferenceClick(Preference preference) {
FragmentClass fc = new FragmentClass();
fc.show(fm, "TAG");
return false;
}
这是我的FragmentClass(TimePicker对话框):
public class FragmentClass extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new TimePickerDialog(getActivity(), this, 15, 00, false);
}
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Log.i("APP", "hour: "+hourOfDay+", …我试图取代fragment的onActivityResult(),但它总是给我的错误java.lang.illegalStateException.

这是我的onActivityResult代码
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment fragment = new VirtualListFragment();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_container, fragment).commit();
}
