Android - Check if a Media player is not installed and show a toast

Issue

I've been trying to get html5 video to play in webview. I actually got that to work but then I had orientation issues. I decided to let a media player handle the file so that it can take care of orientation etc. This seems to work great. However, I do I modify the code so that if a player isn't available it gives a toast and not cause my app to crash? any suggestions?

private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if (Uri.parse(url).getHost().equals("my.site.com")) {
                return false;
            }else if(url.endsWith(".mp4")) {
                Intent intent = new Intent("android.intent.action.VIEW", Uri.parse(url));
                intent.setDataAndType(Uri.parse(url), "video/*");
                view.getContext().startActivity(intent);
                return true;
            }

            // Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity(intent);
            return true;
        }


    }

Solution

If you want to check if the current hardware is able to handle the Intent:

   if(intent.resolveActivity(getPackageManager()) != null){
// start mediaplayer
}else{
//toast no mediaplayer available
}

If you want to check for a specific MediaPlayer ( in this example Google Play Movies):

if(isMediaPlayerAvailable()){
    // start mediaplayer
    }else{
    //toast no mediaplayer available
    }


public static boolean isMediaPlayerAvailable(Context context) {
        String mVersion;
        try {
            mVersion = context.getPackageManager().getPackageInfo(
                    "com.google.android.videos", 0).versionName;
              Log.d("MediaPlayer", "Installed: " + mVersion);
              return true;
        } catch (NameNotFoundException e) {
              Log.d("MediaPlayer", "Not installed");
              return false;
        }
       }

Different approach: Hide Webview, play video in VideoView

You should create a VideoView with android:visiblity="gone" in the layout xml.

else if(url.endsWith(".mp4")) {

view.setVisibility(View.GONE);

   VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview);
   myVideoView.setVisibility(View.VISIBILE);
   myVideoView.setVideoURI(Uri.parse(url));
   myVideoView.setMediaController(new MediaController(this));
   myVideoView.requestFocus();
   myVideoView.start();
            }

You should also look into the different Listeners you can add to a VideoView to revert the Visibility changes when the Video is done playing or is unable to load.
