android - 动态功能 Activity 未加载，卡在安装中

Question

我正在尝试为我的项目实现应用程序包。在启动动态模块 Activity 时，它正在下载模块并尝试安装模块，但无法完全安装。它卡住了，如下图所示。

Answer 1

根据文档，您还需要启用 SplitCompat。您有 3 个选择:

• 选项 1:通过在 AndroidManifest.xml 中定义 SplitCompatApplication 作为默认应用程序

  <application
      ...
      android:name="com.google.android.play.core.splitcompat.SplitCompatApplication" >
  </application>
  

• 选项 2:让您当前的应用程序类扩展 SplitCompatApplication。

  public class MyApplication extends SplitCompatApplication {
      ...
  }
  

• 选项 3:从您的应用程序覆盖 attachBaseContext 方法。

  @Override
  protected void attachBaseContext(Context context) {
      super.attachBaseContext(context);
      // Emulates installation of future on demand modules using SplitCompat.
      SplitCompat.install(this);
  }
