There are six types of dependencies in Android studio
Compile,provided,apk,test Compile,debug compile,release Compile
Compile is for all build type and favlors to be compiled and packaged into the final apk file.
Provided is for all build type and favlors only at compile time, similar to external-libs in Eclipse, only participates in compiling, not packaging to the final apk.
It will only be packaged into the APK file, not compiled, so you can no longer call the class or method in the jar directly from the code, or you will get an error at compile time.
Test compile is only valid for compilation and compilation of unit test code and final package test apk, which does not work for normal debug or release apk packages.
Debug compile only for debug mode compilation and final Debug APK package.
Release compile only for release mode compilation and final release APK package.
