1. In Android Studio, when you create a new Virtual Device, when you get to Select a system image go to the Other images tab. From there select any of the 'arm' images and use that. The emulator will be extremely slow with this option, and might not run at all if your computer is old or slow.
2. Connect a real Android device to your computer with debugging mode enabled and run the demo on that.
3. In your build.gradle file, set compileSdkVersion and targetSdkVersion to 22 which is the latest version in which DJI's provided libffmpeg.so file will load. This is the worst option though, as Google doesn't allow anybody to publish apps with SDK versions this low anymore. The version must be 26 or above now: https://support.google.com/googleplay/android-developer/answer/113469#targetsdk

@SChalice App working on Android Device but not on Emulator! @aleksandrawy Are you still facing the issue or this issue of yours is solved now?

Same issue here. You should upgrade the SDK so that we can use it with the latest version of Android.
