This annotation is used to decorate methods that are to be invoked in an asynchronous way.
Note that the piece of code inside such methods will be automatically protected so to avoid concurrency issues. Though, other parts of the code inside the same class will be not.
In order to prevent unexpected behaviors, it is advisable to avoid using the same class fields (unless immutable) in protected and non-protected code, or to call synchronous methods through routines as well.

Through this annotation, it is possible to indicate the timeout for a readable result to become available.

Finally, be aware that a method might need to be made accessible in order to be called. That means that, in case a java.lang.SecurityManager is installed, a security exception might be raised based on the specific policy implemented.

Remember also that, in order for the annotation to properly work at run time, you will need to add the following rules to your Proguard file (if employing it for shrinking or obfuscation):


         -keepattributes RuntimeVisibleAnnotations

         -keepclassmembers class ** {
