今天遇到一个问题：
Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute application@icon value=(@mipmap/ic_launcher) from AndroidManifest.xml:7:9-43
is also present at [com.pnikosis:materialish-progress:1.0] AndroidManifest.xml:13:9-45 value=(@drawable/ic_launcher).
Suggestion: add 'tools:replace="android:icon"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.
