Proguard中的vs vs ** vs ***？

Question

What is the difference between the * , ** and *** wildcards in Proguard? For example:

-keep class com.mypackage.*

vs

-keep class com.mypackage.**

vs

-keep class com.mypackage.***

Answer 1

*   matches any part of a method name. OR matches any part of a class name not containing the package separator.
**  matches any part of a class name, possibly containing any number of package separators.
*** matches any type (primitive or non-primitive, array or non-array).

Note that the * , and ** wildcards will never match primitive types. Furthermore, only the * wildcards will match array types of any dimension. For example, " get*()" matches "java.lang.Object getObject()" , but not "float getFloat()" , nor "java.lang.Object[] getObjects()" .

Answer 2

*   matches any part of a filename not containing the directory separator.
**  matches any part of a filename, possibly containing any number of directory separators.
