Question

当我使用27和28版API在模拟器上运行我的应用程序时，一切对我都有效。但是，当我尝试使用较低级别的API时，会在我的自定义Activity.java类中收到有关setContentView（）方法的错误消息。

这是堆栈跟踪：

我试图使用版本为24的api在手机和模拟器上运行此应用程序，但没有任何效果。 onCreate（）方法尝试调用的我的activity_main.xml仅包含两个在onCreate（）方法中修改的片段。这是其中的一段代码：

/* This code runs perfectly fine on the version 28 and 27 api on the emulator*/
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    images = new ArrayList<>();
    imageNames = new ArrayList<>();

    setContentView(R.layout.activity_main);
    Log.v(TAG, "I got in onCreate");


    //Create the fragment for the ranking and add it to the current view
    // Get references to the TitleFragment and to the QuotesFragment containers
    mRibbonFrameLayout = findViewById(R.id.ribbon_fragment_container);
    mChecklistFrameLayout = findViewById(R.id.checkbox_fragment_container);

    ...
}

我尝试查找此问题，但没有发现任何解决该问题的方法-至少是公开进行的。

更新，当我发现某个文件夹的版本为26（这会限制使用该版本）后，在5分钟内解决了该问题。

Android-v24 API之前的setContentView（）崩溃
