Initialize mPaaS - Mobile Platform as a Service - Alibaba Cloud Documentation Center

Before you use the mPaaS framework, you need to initialize the Application object based on whether the Hotpatch feature is enabled. This topic describes the initialization processes in both cases.

When Hotpatch is disabled

When the Hotpatch feature is disabled, you need only to add the following code to the Application object.

@Override
public void onCreate() {
    super.onCreate();
    
    MP.init(
      this,
      MPInitParam.obtain().setCallback(new MPInitParam.MPCallback() {
        @Override
        public void onInit() {
            Log.d("TAG", "mPaaS Init finish");
        }
      })
    );
}

Note

If you integrate Kotlin, you can use mPaaS Kotlin Extension of mPaaS KTX provided by mPaaS.
If you need to continue to use the QuinoxlessFramework initialization method, your calls will not be affected in any way, and no changes to the code or business are required.

Important

Please do not filter the process before using the MP.init method. In addition to the main process, initialization code also needs to be executed in the tools and push child processes.

When Hotpatch is enabled

When the Hotpatch feature is enabled, perform the following steps.

Procedure

In the Application object, re-inherit QuinoxlessApplicationLike and exclude this class from obfuscation. In the following code, the MyApplication object is used as an example.

 @Keep
 public class MyApplication extends QuinoxlessApplicationLike implements Application.ActivityLifecycleCallbacks {

  private static final String TAG = "MyApplication";

  @Override
  protected void attachBaseContext(Context base) {
      super.attachBaseContext(base);

      Log.i(TAG, "attacheBaseContext");

  }

  @Override
  public void onCreate() {
      super.onCreate();
      Log.i(TAG, "onCreate");
      registerActivityLifecycleCallbacks(this);
  }

  @Override
  public void onMPaaSFrameworkInitFinished() {
      LoggerFactory.getTraceLogger().info(TAG, getProcessName());
  }

  @Override
  public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
      Log.i(TAG, "onActivityCreated");
  }

  @Override
  public void onActivityStarted(Activity activity) {

  }

  @Override
  public void onActivityResumed(Activity activity) {

  }

  @Override
  public void onActivityPaused(Activity activity) {

  }

  @Override
  public void onActivityStopped(Activity activity) {

  }

  @Override
  public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

  }

  @Override
  public void onActivityDestroyed(Activity activity) {

  }}

In the AndroidManifest.xml file, ensure that the Application object inherits the Application object provided by mPaaS. Then, add the generated MyApplication class to meta-data whose key is mpaas.quinoxless.extern.application. The following sample code is for your reference.
```
 <application
 android:name="com.alipay.mobile.framework.quinoxless.QuinoxlessApplication" >
 <meta-data
          android:name="mpaas.quinoxless.extern.application"
          android:value="com.mpaas.demo.MyApplication"
          />
 </application>
```
Import the Apache HTTP client.
When you use Remote Procedure Call (RPC) or Hotpatch, you need to call the features of the Apache HTTP client. Therefore, add the following code to the AndroidManifest.xml file. For more information, see Use the Apache HTTP client.
```
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
```
