OpenGL ES 2.x and higher are the way to go, so you probably won't get around coding your own shaders. That comes with a lot of advantages and a few problems. Yes there are some compatibility issues but they are universal and also affect desktop GPUs due to subtle inconsistencies in driver implementations. The article you linked to points out the main problems I also encountered. However, those issues do not mean that you should avoid using the OpenGL ES 2.x and higher. Take it as a list of best practices to follow.
You should also read through the following blog about OpenGL ES programming for Android: http://www.learnopengles.com/android-lesson-one-getting-started/ The articles there also explain how to bind textures, prepare and upload vertex data and so on. I hope they will answer your other questions. In my experience you won't run into big problems with most basic shader approaches. That cross-fading effect should not cause any issues.
