Can I create an annotation that will make the class call
Log.e("", "")
and have the class in which the method is in's name as the first argument and the method name as the second argument?
Something like this:
public class UploaderService {
@Debuggable
void onUploadProductSuccess(int productServerId) {
}
}
Logcat output:
UploaderService | onUploadProductSuccess 43
Also are there any caveats in using this in Android?
Your question is already answered here. So in short, yes and sort of. You can create custom annotations for logging or any other purpose, but you have to implement a code that checks for annotations in classes, using reflection that is available for Android as well.
If this is important for you then you should create a proxy object that gets a service name, method + paramlist params.
Something like this:
Call:
callServiceMethod("UploaderService","onUploadProductSuccess",productServerId);
Method source:
public void callServiceMethod(String serviceName, String methodName, Object... paramList){
Object service = ;//getting the service object by name
//getting the method
Method method = service.getClass().getMethod(methodName, paramList[0].class,...);
for ( Annotation a : m.getAnnotations() ) {
// if the annotation found then write to log
}
//in the end:
method.invoke(service , paramList[0], ...);
}
in this method you can check the called service for your annotations before calls the actual method.
As you can see the method is called and the log is written, but instead of calling UploaderService.onUploadProductSuccess you have to call the method above.
