String str_result= new OnlineAsyncTask().execute().get();

This will make it wait till it returns the value

You can call get() to wait for the async task to complete and retrieve the result.

However that defeats the purpose of an async task - it's no longer asynchronous. Consider redesigning your app so that you don't need to wait for a result. Instead e.g. use a callback interface to notify that the async task has finished and a result is available.
