Android intent for playing video

Question

I m trying to play video s on Android  by launching an intent  The code I m using is   tostart   new Intent Intent ACTION VIEW   tostart setDataAndType Uri parse movieurl    video      startActivity tostart      This works on most phones  but not on the HTC Hero  It seems to load a bit different video player  This does play the first video thrown at it  However  every video after that it doesn t respond   it keeps in some loop    If I add an explicit   tostart setClassName  com htc album   com htc album ViewVideo       before the startactivity  it does work on the HTC Hero  However  since this is a HTC specific call  I can t run this code on other phones  such as the G1   On the G1  this works   tostart setClassName  com android camera   com android camera MovieView      g1 version   But this intent is missing from the hero  Does anybody know a list of intents classnames that should be supported by all Android devices  Or a specific one to launch a video  Thanks

from the debug info  it seems that the VideoIntent from the MainActivity cannot send the path of the video to VideoActivity  It gives a NullPointerException error from the uriString  I think some of that code from VideoActivity   Intent myIntent   getIntent    String uri   myIntent getStringExtra  uri    Bundle b   myIntent getExtras     startVideo b getString uri      Cannot receive the uri from here   public void playsquirrelmp4 View v        Intent VideoIntent    new Intent this  VideoActivity class        VideoIntent putExtra  android resource       getPackageName                    R raw squirrel  uri       startActivity VideoIntent

I have come across this with the Hero  using what I thought was a published API  In the end  I used a test to see if the intent could be received   private boolean isCallable Intent intent        List lt ResolveInfo gt  list   getPackageManager   queryIntentActivities intent           PackageManager MATCH DEFAULT ONLY       return list size    gt  0      In use when I would usually just start the activity    final Intent intent   new Intent  com android camera action CROP    intent setClassName  com android camera    com android camera CropImage    if  isCallable intent            call the intent as you intended    else          make alternative arrangements      obvious  If you go down this route - using non-public APIs - you must absolutely provide a fallback which you know definitely works  It doesn t have to be perfect  it can be a Toast saying that this is unsupported for this handset device  but you should avoid an uncaught exception  end obvious     I find the Open Intents Registry of Intents Protocols quite useful  but I haven t found the equivalent of a TCK type list of intents which absolutely must be supported  and examples of what apps do different handsets

From now onwards after API 24  Uri parse filePath  won t work  You need to use this  final File videoFile   new File  path to your video file    Uri fileUri   FileProvider getUriForFile mContext    yourpackagename  fileprovider   videoFile   Intent intent   new Intent Intent ACTION VIEW   intent setDataAndType fileUri   video      intent addFlags Intent FLAG GRANT READ URI PERMISSION    DO NOT FORGET THIS EVER startActivity intent     But before using this you need to understand how file provider works  Go to official document link to understand file provider better
