Has anyone got this error while creating an Android App.?
This error occurs while I do a “Generate a Signed APK” in Android Studio (v.2.3.2) . I use
compile 'io.particle:devicesetup:0.5.2'. It seems to indicate that Java 8 was used. I tried using
targetCompatibility = '1.8'
sourceCompatibility = '1.8'
but still getting the same 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.
