无法将android.support.multidex.MultiDexApplication异常强制转换为类

问题描述

我认为您应该将AnalyticsApplication班级扩展到自己的班级，如下所示：

public class YourApplicationName extends AnalyticsApplication {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);

          setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
          requestWindowFeature(Window.FEATURE_NO_TITLE);
          setContentView(R.layout.activity_splash);

          //Analitycs
          AnalyticsApplication application = (AnalyticsApplication) getApplication();
          mTracker = application.getDefaultTracker();
          mTracker.setScreenName("Splash");
          mTracker.send(new HitBuilders.ScreenViewBuilder().build());
     }

     // Here you will enable Multidex
     @Override
     protected void attachBaseContext(Context base) {
          super.attachBaseContext(base);
          MultiDex.install(getBaseContext());
     }

}

之后，您必须将AndroidManifest.xml文件更改为此：

<application
     android:name="path.to.YourApplicationName"
     ...

解决方法

我有一个问题，我的应用生成了此异常，我听不懂。我已经在我的build.gradle中实现了multiDexEnabled

  Caused by: java.lang.ClassCastException: android.support.multidex.MultiDexApplication cannot be cast to com.example.AnalyticsApplication

我的班级Java

public class Splash extends Activity {

 private Tracker mTracker;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  setContentView(R.layout.activity_splash);

  //Analitycs
  AnalyticsApplication application = (AnalyticsApplication) getApplication();
  mTracker = application.getDefaultTracker();
  mTracker.setScreenName("Splash");
  mTracker.send(new HitBuilders.ScreenViewBuilder().build());

}

文件摇篮

 defaultConfig {
    multiDexEnabled true
}

Manifest.xml

<uses-permissionandroid:name="android.permission.INTERNET"/>
<uses-permissionandroid:name="android.permission.ACCESS_NETWORK_STATE"/>

<application
android:name="android.support.multidex.MultiDexApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
