在项目中遇到了一个 Bug :
No resource found that matches the given name ‘android:TextAppearance.Material.Widget.Button.Borderless.Colored’.
经过请教，发现问题来自 compileSdkVersion 和 依赖的第三方库的 support 版本不同，compileSdkVersion 版本低于 support 版本，在编译的时，就会找不到一些 support 需要的资源。解决的方法：
compile(xxx) {
exclude module: 'support-v4'
exclude module: 'appcompat-v7'
}
关键字 exclude 。参考 https://medium.com/mindorks/avoiding-conflicts-in-android-gradle-dependencies-28e4200ca235
如果你需要展示依赖关系的话，碰巧在解决上面的过程中我发现了一个命令，还比较有用。
./gradlew -q app:dependencies --configuration debugCompileClasspath
