Android: VideoView within Fragment only playing audio, not displaying video

I have a fragment that allows users to select from a mixed list of video and image content. When selecting a multimedia item, display is toggled between an `ImageView` and `VideoView` depending on the media type. The problem is, when the user selects a video, only the audio is played, and the `VideoView` remains black. This is the code for displaying video: (Most of the code at the bottom is trial-and-error to see if something is missing to fix this issue) ``` mainVideo.setVisibility(View.VISIBLE); mainImage.setVisibility(View.INVISIBLE); getActivity().getWindow().setFormat(PixelFormat.TRANSLUCENT); parent.showLoader(R.string.buffering); mainVideo.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { parent.hideLoader(); mainVideo.requestFocus(); mainVideo.start(); } }); mainVideo.setOnErrorListener(new MediaPlayer.OnErrorListener() { @Override public boolean onError(MediaPlayer mp, int what, int extra) { showErrorMessage(R.string.multimedia_load_failed, R.string.please_try_again_later); parent.hideLoader(); return true; } }); Uri video = Uri.parse(mm.url); mainVideo.setMediaController(new MediaController(parent)); mainVideo.setKeepScreenOn(true); mainVideo.bringToFront(); mainVideo.setDrawingCacheEnabled(true); mainVideo.setActivated(true); mainVideo.setEnabled(true); mainVideo.setVideoURI(video); Log.i(TAG, "Loading video: " + video.toString()); ``` (`parent` is a reference to the activity that has some convenience functions like `showLoader` and whatnot.) Here is my layout: ``` <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <FrameLayout android:layout_width="275dp" android:layout_height="275dp" android:layout_gravity="center_horizontal" android:padding="1dp" android:background="@color/light_grey"> <ImageView android:id="@+id/mm_main_image" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/black" android:scaleType="fitXY"/> <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent"> <VideoView android:id="@+id/mm_main_video" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_alignParentRight="true"> </VideoView> </RelativeLayout> </FrameLayout> <TextView android:id="@+id/mm_index_count" android:layout_width="wrap_content" android:layout_height="20dp" android:textAppearance="?android:attr/textAppearanceSmall" android:layout_margin="@dimen/large_padding" android:layout_gravity="center_horizontal" android:textColor="@color/white"/> <HorizontalScrollView android:id="@+id/mm_horizontal_scroll" android:layout_height="110dp" android:layout_width="wrap_content"> <LinearLayout android:id="@+id/mm_media_list" android:layout_height="match_parent" android:layout_width="wrap_content"> <!-- Content filled dynamically --> </LinearLayout> </HorizontalScrollView> </LinearLayout> </ScrollView> ``` I have looked all over StackOverflow and around the web for the last two days, but cannot find a solution to this problem anywhere. Any help is appreciated. All of the videos (and images for that matter) are remote, they are not on the Android device.
