Android AppcompatActivity with fragments 在从后台加载后崩溃（需要等待几分钟）
Android AppcompatActivity with fragments crashes after bringing from background(need to wait couple minutes)
您好，我遇到了带有片段的 AppCompatActivity 问题
我已经使用处理片段的 AppCompatActivity 扩展了一个 class，当用户发送应用程序后台并等待几分钟然后将应用程序带到前台时会出现问题。除了那种情况，它根本不会崩溃。 （一些不必要的代码还在开发中，请不要关注它们）
任何帮助将不胜感激，我已经在这一点上停留了几天。
如果还有其他需要，我可以更新问题并添加它们
public class SurveyMainFragment extends AppCompatActivity{
private Toolbar toolbar;

我通过更改片段解决了问题
<fragment
android:id="@+id/fragment_survey_place"
android:name="com.example.app.emptyFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/test" />
和
<FrameLayout
android:id="@+id/fragment_survey_place"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/test"/>
到目前为止没有崩溃

我通过更改片段解决了问题
<fragment
android:id="@+id/fragment_survey_place"
android:name="com.example.app.emptyFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/test" />
和
<FrameLayout
android:id="@+id/fragment_survey_place"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="@+id/test"/>
到目前为止没有崩溃
