From the literal meaning of the V4 packet repeatedly caused by the error, thought this simple, so in the app's Libs view, delete, because I am using the form of online compilation

So look under the dependency tree

Find V4 packages in almost every project

Google found a method after

Compile (' your package ') {

exclude group: ‘com.android.support‘, module: ‘support-v4‘

}

The meaning of this method is: The V4 package is excluded when compiling the package
