I have found a solution. I am pasting it here so it may help other users.

    Intent intent = new Intent();
    intent.setAction(android.content.Intent.ACTION_VIEW);
    File file = new File(path);

    MimeTypeMap mime = MimeTypeMap.getSingleton();
    String ext = file.getName().substring(file.getName().lastIndexOf(".") + 1);
    String type = mime.getMimeTypeFromExtension(ext);

    intent.setDataAndType(Uri.fromFile(file), type);

    context.startActivity(intent);

Before `context.startActivity(intent);`, you should add these lines (to show `Toast` if no app found to open the file: `PackageManager manager = mActivity.getPackageManager(); List info = manager.queryIntentActivities(intent,PackageManager.MATCH_DEFAULT_ONLY); if(info.isEmpty()) Toast.makeText(mActivity, "No app found to open this file", Toast.LENGTH_SHORT).show(); else context.startActivity(intent);` – Sufian Jul 11 '14 at 05:26
Shouldn't it be: file.getName().lastIndexOf(".") rather than just indexOf ? – Myoch Aug 11 '18 at 18:40

You should decide and know whether the file is video or image. You may do it by looking at the extension of the files.

After that you can open videos like this:

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.parse(result), "video/*");
startActivity(intent);

and images like this:

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
    intent.setDataAndType(Uri.parse(result), "image/*");
startActivity(intent);

Android system will open the Intent Chooser automatically.

You have misunderstood my question. I don't want to open only image or video. I want that whatever file i pass, intent chooser lists appropriate application for that file. – Unnati Apr 18 '14 at 07:29
Ok then you just need to change the type parameter accordingly. If it is text "text/*" it should be. You cannot do it automatically I guess. In most of the file explorers they categorize them into text, images, videos and open them accordingly. For all the files that not fit a category, they ask user what kind of a file this. – tasomaniac Apr 18 '14 at 07:33
I have found a solution. See my answer. Thanks :) – Unnati Apr 18 '14 at 07:36
