标签： java android android-fragments

当用户重新打开应用时，我的Android应用会出现此错误。应用程序第一次正常打开。它只是发生在一些设备（有时），我无法解决它。 Stackoverflow中有一些关于它的问题，但没有一个对我来说是正确的。

以下是Firebase崩溃的完整错误：

的活动：

public class PrincipalActivity extends FragmentActivity {

    private FragmentManager fragmentManager;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_principal);

             mFragmentManager = getSupportFragmentManager();
        getSupportFragmentManager().beginTransaction().add(R.id.fragment_place, anotherFragment).commit();

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v = inflater.inflate(R.layout.fragment_empty, container, false);



        return v;
    }


}

尝试更改您的片段。

从：

<fragment
        android:id="@+id/fragment_place"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/divider"
        class = "com.app.Activities.Activities.EmptyFragment"
        />

为：

<fragment
        android:name="com.app.Activities.Activities.EmptyFragment"
        android:id="@+id/fragment_place"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/divider"
        />

并将此行代码移至PrincipalActivity。

mFragmentManager = getSupportFragmentManager();
        getSupportFragmentManager().beginTransaction().add(R.id.fragment_place, anotherFragment).commit();

希望这有帮助！
