Note: When you import a ring letter, you may encounter a conflict between the V4 package and the V7 package, and you need to remove the V4 package. The solution is as follows: Add the Exclude module: ' Support-v4 ' below the V7 package in Build.grade:
Compile (' com.android.support:appcompat-v7:23.4.0 ') {Exclude module: ' Support-v4 '}
