Issues on Galaxy Tab A (Urgent!)

Hi, I am developing an AR app that's specifically going to run on a Samsung Galaxy Tab A 9.7 tablet(model no. - SM T550) with Android 5.0.2. The app displays a transparent video overlay when a target image is recognized and a Read more button which opens a new Activity (non-AR). The app runs perfectly fine on my OnePlus One phone (Android 5.0.2) and Xiaomi MiPad (Android 4.4). However, it keeps crashing / stuck on black screens and the video overlay does not show either on the Galaxy Tab A. Even the sample app that comes with the SDK gets stuck on a black screen when any option is selected but works fine on the other devices. Below is the log from my app. Please help!

Hi,

we are not aware of issues like the one you described, and this seems to be a device-specific problem.
Could you please give us more information about it?

- Which version of the Wikitude SDK are you using? Can you test with the sample application of a dfferent SDK Version? If you use the latest 5.0, we can provide you a link to the previous version.

- Can you play the same media fie (or URL) using the media player on the same device?

- Have you already tried resetting the device?

Hi,

I am using the latest version 5.0 of the SDK.  Please provide links to some older versions of the SDK. I can play the video file using the default media player on the device. I reset the device and now the transparent video example of the sample app works but the video overlay still doesn't show up in my own app. However, it works fine on my other devices. I'm also seeing this error on the logs sometimes : "Error while loading the video. (Media player - unknown error Network timed out while streaming video )"

I modified the transparent video example in the sample app to use my custom .wtc file and transparent video file and it ran fine. However, when I imported the same javascript file and video into my project, it again throws this error - " E/l? Error while loading the video. (Media player - unknown error  )". I also tried changing the minimum sdk version and target sdk version on my app to be the same as the sample app but it didn't work.
