Android, Impossible to build app due to a google.gson.JsonSyntaxException (Excepted BEGIN_ARRAY but was STRING at line 1 column 1 path $) : I'm developing in Android Studio. Today I made some fix to my app, save all and than start debbugging it on my connected via usb phone. My pc freezed, so I restarted it, reopened Android Studio, reopened my project, checked if all the fixes was saved and than try again to debug it on my phone. And the Gradle Build gave me an error under "Run Tasks" > ":app:transformClassesWithDexBuilderForDebug" > "Execute transform". I really don't know what the error is, by what it was caused and how to fix it. Anyone can help?
