Goal - watch top-ten videos back to back without delay in android app

I read about adaptive streaming(HLS/DASH) cdn like amazon cloudfront, hola, streamable.

Unfortunately, none of their given examples work. Each throws a unique error which I am unable to resolve. Amazon & Streamable, support staff does not respond.

When using Amazon Cloudfront Tutorial sample app, I was getting following error - "No Viewing App exists for content type - application/octeam-stream", so I created a VideoPlayerActivity that uses ExoMedia to play videos.

I get the following error

Caused by: java.lang.IllegalArgumentException: Unable to find configured root for content://com.mysampleapp.fileprovider/s3_lolwow-contentdelivery-mobilehub-2118977425/content/HLS/Popeye_forPresident_512kb-1490367405276/output/2M_v4.m3u8

I modified 'name' attribute in content_delivery_paths.xml because changing name should not make any difference

Original

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="." path="/"/> 
</paths>

Modified

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="videos" path="/"/> 
</paths>

Now I'm getting the following error

com.amazon.mysampleapp E/ExoPlayerImplInternal: Internal track renderer error. com.google.android.exoplayer.ExoPlaybackException: com.google.android.exoplayer.upstream.ContentDataSource$ContentDataSourceException: java.io.FileNotFoundException: No such file or directory

Multiple attempts later I decided to switch and try streamable.com but encountered this error, their support team does not respond to any queries.

Can anyone guide me through this?
