Proguard  returned with error code 1. See console  
Warning: com.google.android.gms.ads.formats.NativeAdView: can't find referenced       method 'FrameLayout(android.content.Context,android.util.AttributeSet,int,int)'   in class android.widget.FrameLayout  
     You should check if you need to specify additional program jars.  
     Warning: there were 1 unresolved references to program class members.  
     Your input classes appear to be inconsistent.  
     You may need to recompile them and try again.  
     Alternatively, you may have to specify the option   
     '-dontskipnonpubliclibraryclassmembers'.  
    java.io.IOException: Please correct the above warnings first.

我将项目构建目标从 Android 4.4.2 更改为 Android 5.1.1，然后问题不再发生。

希望对你有帮助。
