I suffer sluttering playback and glitches on android platform

The default playback buffer size is set to 1024 frames, it can be too low for some android devices resulting in audio playback glitches.
You can increase the buffer size using the Init Player Audio Ex node and power 2 values like 2048 or 4096.

I got a notification «Plugin failed to load» when the packaged build starts, only on android arm64 platform

The UE4 marketplace plugin builder system doesn’t create the binaries of android arm64 platform so you get the error:
Plugin ____ failed to load because module ____ could not be found. Plese ensure the plugin is properly installed, otherwise consided disablen the plugin for this project.

Android error capture

This is only a workaround until Unreal Engine 4 team fixes the thirdparty builder system. Just move the AudioAnalyzer folder from your Engine Plugins folder
(EpicGames\UE_4.xx\Engine\Plugins\Marketplace\AudioAnalyzer\)
to your project (ProjectFolder\Plugins\Marketplace\AudioAnalyzer\)

If you are using the plugin in more than one project you can place a copy in each project
