Android validating a url
Let me explain the scenario that I am going to accomplish with this blog post. I want to send some confidential data to a different server by using one of my native Android application.
Annotations allow you to provide hints to code inspections tools like Lint, to help detect these more subtle code problems. Toast; public class My Http Post Project Activity extends Activity implements On Click Listener method code set that I have posted in my previous post.to identify strings, graphics, colors, and other resource types, so inspection tools cannot tell when you have specified a string resource where you should have specified a color.Code that expects a parameter to reference a specific type of resource, for example Drawables, can be passed the expected reference type of can be added using the same annotation format and run during the code inspection.If your parameter supports multiple resource types, you can put more than one of these annotations on a given parameter. However, it's possible for a UI thread to be different from the main thread in the case of system apps with multiple views on different threads.They are added as metadata tags that you attach to variables, parameters, and return values to inspect method return values, passed parameters, local variables, and fields.
When used with code inspections tools, annotations can help you detect problems, such as null pointer exceptions and resource type conflicts.
This annotation is typically added to methods and classes that are accessed through reflection to prevent the compiler from treating the code as unused.
For more information about how to minify your code and specify which code should not be removed, see Shrink Your Code and Resources.
Note: When adding nullness annotations, autocomplete may suggest the Intelli J annotations instead of the Android null annotations and may auto-import the corresponding library.
However, the Android Studio Lint checker only looks for the Android null annotations.
Use the following annotations to denote the visibility of specific portions of code, such as methods, classes, fields, or packages. Only your library code can access the annotated API.
