[JAVA] Allows Youtube autoplay on Cordova's Android app

Preface

Media autoplay such as Youtube and other functions (*) in mobile application development It is turned off to prevent unnecessary communication, not only when developing native apps The same is true when developing a hybrid app using JavaScript + Cordova.

• Not only automatic playback, but also after the user first presses the play button Play stop jump and various other media controls cannot be performed from the code.

The Cordova Options (https://cordova.apache.org/docs/en/latest/config_ref/index.html) to turn this on exists in iOS but not in Android. However, "Well, can't youtube autoplay only on Android in development using Cordova: cry:" That's not the case, it's in Android's native app settings API By hitting the method setMediaPlaybackRequiresUserGesture (true / false) You can activate it.

Code fix

File to mess with (com / example / hoge is the app name and namespace. Please read as appropriate.)

platforms/android/app/src/main/java/com/example/hoge/MainActivity.java

import android.os.Bundle;
import org.apache.cordova.*;
import android.webkit.WebSettings; //★ Addition
import android.webkit.WebView; //★ Addition

public class MainActivity extends CordovaActivity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // enable Cordova apps to be started in the background
        Bundle extras = getIntent().getExtras();
        if (extras != null && extras.getBoolean("cdvStartInBackground", false)) {
            moveTaskToBack(true);
        }

        // Set by <content src="index.html" /> in config.xml
        loadUrl(launchUrl);
        
        //★ Addition
        WebView wv = (WebView) appView.getEngine().getView();
        WebSettings ws = wv.getSettings();
        ws.setMediaPlaybackRequiresUserGesture(false);
    }
}

Serpentine

If you don't want to keep platforms and below under Git control, save the MainActivity.java file in a different location I think it's better to version control it and use Cordova's hook function to move it before building.

config.xml

<platform name="android">
  <hook type="before_build" src="scripts/updateMainActivity.sh" />
  ...

scripts/updateMainActivity.sh

#!/bin/bash

#For example native_If you have MainActivity in codes
cp native_codes/MainActivity.java platforms/android/app/src/main/java/com/example/hoge/MainActivity.java
