I use an 5.1 device (tablet) and try to compile my symple app (actually only bottom navigation activity layout ... empty ... and nothing else) but I have a long list of 26 error during the Debug ....

I've just modified it (before support was for 1_7 version) .... but I have these error .... if return to old version with VERSION_1_7 && jackOptions == false ... obtain these 3 error:
Error:Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.
This is caused by library dependencies that have been compiled using Java 8 or above.
If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.
Error:1 error; aborting

I have a module ... an external library .. but without dependancy ...
We need to use webrtc API.
some suggest how to solve these error?
EDIT:
remove the module ... nothing change ... same error.
