Application code may spawn more than one worker thread.

Example:
1 dedicated thread for local SQLite operations
pool of threads for disk operations
pool of threads for network operations

Suggested change is to add property for @WorkerThread as following:

    @Retention(CLASS)
    @Target({METHOD,CONSTRUCTOR,TYPE,PARAMETER})
    public @interface WorkerThread {
+        String value() default "";
    }

This value may be treated as logical ID of thread or pool.

Then do corresponding changes in Lint. It must detect calls from wrong thread, assuming that each unique 'value' of the @WorkerThread represents single thread.

Example:

@WorkerThread("network")
public void onCallbackFromNetwork() {
    // here Line must warn about WrongThread
    doSomethingInDatabase();
}

@WorkerThread("database")
public void doSomethingInDatabase() {
}
