推荐答案
请将以下内容添加到您的proguard文件中.
Please add the following to your proguard file.
# keep classes with the `View(Context, Attributes)` constructor
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);
}
# keep classes with the `View(Context, Attributes, int)` constructor
-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}
# keep methods that accept a view as their argument.
# This would be the case if you set an onclick from an xml file
-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}
# keep all of the design library
-keep class android.support.design.** { *; }
# keep all android classes
-keep class android.** { *; }
# keep all class members, don't rename methods
-keepclassmembers class android.** { *; }
