simple trick to autoplay an html5 video element in a webview. (inject javascript to play on load)

autoplay.java

import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
  private WebView webview;

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

        webview = new WebView(this);
        setContentView(webview);

        final WebSettings settings = webview.getSettings();
        settings.setJavaScriptEnabled(true);
        settings.setJavaScriptCanOpenWindowsAutomatically(true);
        settings.setPluginState(WebSettings.PluginState.ON);

        webview.setWebViewClient(new WebViewClient() {
            // autoplay when finished loading via javascript injection
            public void onPageFinished(WebView view, String url) { webview.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()"); }
        });
        webview.setWebChromeClient(new WebChromeClient());

        webview.loadUrl("http://html5demos.com/video");
    }

    @Override
    protected void onPause() {
        super.onPause();
        webview.onPause();
    }

    @Override
    protected void onResume() {
        webview.onResume();
        super.onResume();
    }
}

I cant see video but its playing I can hear audio of video

same here @prasad456

Same here, only audio is playing.

Add android:hardwareAccelerated="true" in application Menifist

I'm having a similar problem, I use several YouTube videos on my site, and auto-play does not work.

My site is this www.pipocaplayfm.com/mobile_play

I mounted a webview app, but it does not work ... can you help me?

This might help:

@Override
protected void onResume() {
    webView.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()");
    super.onResume();
}

I've added that JavaScript code in onResume.

Thank you so much. I can do it!
