How to integrate Super App with Native android application?

[asadpstu]

Problem background:
I have integrated a standalone react-native application with native android app by following react-native website guidelines. I was able to access my react-native application from native android application. But, in case of integrating Super App with native android application, it keeps crashing.

As a single Super App, my app is running. I can install the apk in my android device and it works like a charm.

It would be very helpful if anyone can help in the matter by sharing ideas, github repo link etc.

Here is some code sample for native android -

`package com.example.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;

import com.facebook.react.PackageList;
import com.facebook.react.ReactInstanceManager;
import com.facebook.react.ReactPackage;
import com.facebook.react.ReactRootView;
import com.facebook.react.common.LifecycleState;
import com.facebook.react.modules.core.DefaultHardwareBackBtnHandler;
import com.facebook.soloader.SoLoader;

import java.util.List;

public class MyReactActivity extends Activity implements DefaultHardwareBackBtnHandler {
private ReactRootView mReactRootView;
private ReactInstanceManager mReactInstanceManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    SoLoader.init(this, false);

    mReactRootView = new ReactRootView(this);
    List<ReactPackage> packages = new PackageList(getApplication()).getPackages();

    mReactInstanceManager = ReactInstanceManager.builder()
            .setApplication(getApplication())
            .setCurrentActivity(this)
            .setBundleAssetName("index.android.bundle")
            .setJSMainModulePath("index")
            .addPackages(packages)
            .setInitialLifecycleState(LifecycleState.RESUMED)
            .build();

    mReactRootView.startReactApplication(mReactInstanceManager, "rnsuperapp", null);

    setContentView(mReactRootView);
}

@Override
public void invokeDefaultOnBackPressed() {
    super.onBackPressed();
}

}`

Android project setup:

AndroidMenifest.xml

`

    <activity
        android:name=".MainActivity"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MyReactActivity"
        android:label="@string/app_name"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize" />

</application>
