相信大家都会遇到如下图所示的问题：

如果引用的第三方库的支持库版本低于（或者不一致）app build.gradle中的支持库版本，可能会出现如下问题：

all com.android.support libraries must use the exact same version specification(mixing versions can lead to runtime crashes)

解决办法就是：在app build.gradle中添加：

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '25.3.1'
            }
        }
    }
}
