Start the trim video activity with an intent

问题:

I can take a video with an intent now what are the details to create an intent to start the default video trimmer activity? And check if it present on the device?

This solution relies on a version of the AOSP Gallery2 package being installed on the device. You can do it like this:

// The Intent action is not yet published as a constant in the Intent class // This one is served by the com.android.gallery3d.app.TrimVideo activity // which relies on having the Gallery2 app or a compatible derivative installed Intent trimVideoIntent = new Intent("com.android.camera.action.TRIM");  // The key for the extra has been discovered from com.android.gallery3d.app.PhotoPage.KEY_MEDIA_ITEM_PATH trimVideoIntent.putExtra("media-item-path", getFilePathFromVideoURI(this, videoUri)); trimVideoIntent.setData(videoUri);  // Check if the device can handle the Intent List list = getPackageManager().queryIntentActivities(trimVideoIntent, 0); if (null != list && list.size() > 0) {     startActivity(trimVideoIntent); // Fires TrimVideo activity into being active }

The method getFilePathFromVideURI is based on the answer of this question: Get filename and path from URI from mediastore

public String getFilePathFromVideoURI(Context context, Uri contentUri) {     Cursor cursor = null;     try {         String[] proj = { MediaStore.Video.Media.DATA };         cursor = context.getContentResolver().query(contentUri,  proj, null, null, null);         int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);         cursor.moveToFirst();         return cursor.getString(column_index);     } finally {         if (cursor != null) {             cursor.close();         }     } }

videoUri is an Uri pointing to something like this: content://media/external/video/media/43. You can gather one by issuing an ACTION_PICK Intent:

Intent pickVideoUriIntent =  new Intent(Intent.ACTION_PICK, MediaStore.Video.Media.EXTERNAL_CONTENT_URI); startActivityForResult(pickVideoUriIntent, PICK_VIDEO_REQUEST);

In onActivityResult get the uri like so:

.... case PICK_VIDEO_REQUEST:     Uri videoUri = data.getData();      ...

This solution works on my Galaxy Nexus with Android 4.3 Jelly Bean.

I am not sure if this is available on all Android devices. A more reliable solution may be to fork the Gallery2 app and put the TrimVideo activity together with its dependencies into a library that can be delivered with your app. Hope this helps anyway.

Try this may it helps

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE); intent.putExtra("android.intent.extra.durationLimit", 30000); intent.putExtra("EXTRA_VIDEO_QUALITY", 0); startActivityForResult(intent, ActivityRequests.REQUEST_TAKE_VIDEO);

This code works well on API >=2.2, but the duration limit does not work on API 2.1
