当我实现这个[com.android.support:animated-vector-drawable:27.0.2]时,它告诉我必须升级到[com.android.support:appcompat-v7:27.0.2]让我在最后的方式升级所有实现任何想法如何解决它?
All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 27.0.2, 26.1.0. Examples include com.android.support:animated-vector-drawable:27.0.2 and com.android.support:design:26.1.0 less
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)
