How to play video using Intent in Android?

Few weeks ago I decided to make an app, this app contained just video links that allows the users to watch clips whenever they click any button link.

I am using this code to play video:

Intent intent = new Intent(Intent.ACTION_VIEW); 
int开发者_开发问答ent.setDataAndType(Uri.parse("http://www.yourvideo.mp4"), "video/mp4"); 
view.getContext().startActivity(intent); 

However, in some cases this code doesn't work in several devices, some users of my app said it force closes the entire app whenever they press any link. I actually tried it in my G1 and Droid X, it worked perfectly fine.

Is there anything I am doing wrong? Please help me, I would really appreciate it a lot.

First, the video may have issues, as not all videos are safe for streaming.

Second, not all devices may have activities set up to support ACTION_VIEW on video/mp4 files that are streamed. You should use PackageManager and queryIntentActivities() to confirm whether the startActivity() call will find a match, or handle the ActivityNotFoundException that you get.

I wrote this :

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("http://www.yourvideo.mp4"), "video/mp4");

Then i add the permission : android.permission.WRITE_EXTERNAL_STORAGE , to my manifest.
