How to Write a User Guide for Android
A well-written user guide will facilitate the end-user in using your app. However, this type of documentation may not be able to gauge the end-user's capability until they use it. This is why it is important to have a thorough testing process before marketing your app. Developers and engineers can help you in this process, but you should also assign beta testers or real users to test it first. It is also a good idea to include the feedback received by users in the user guide.
A user guide should be organized according to the use pattern of the product. This way, the content is easy to access and navigate. For example, if your app uses a list view, the user should be able to access it through the main menu. Once there, tap the module name to open the list view. After that, tap the three-bar icon to return to the main menu.
