I thought that somebody might find the following interesting.
I used to use a Kindle for reading but I switched to using only the Android Kindle app as a long-standing bug in the Kindle software meant that library changes didn't sync properly with my Android devices. The drawback with using most Android devices is that reading their screens outside in strong sunlight is difficult so I looked for an Android device with an e-Ink screen and found that, as far as I can tell, they are available from only one Chinese manufacture called Onyx who produce a line of products called 'Boox' which are intended for and mainly configured as eReaders but you can actually just use them as Android devices although the UI is rather different to what you are used to and only a subset of the normal settings are available. They can access the Play Store and yes, B4A-Bridge works and I have installed some of my own software with no problems on both the devices I have - though they don't have GNSS and various other sensors are missing.
I started last year with a Boox Poke 5 which uses the same 6" black and white e-Ink screen as the small Kindles and it works well as a reader, although a bit sluggish at times and I think it is no longer available. Onyx have just launched a successor, the Boox Go Color 7 with a 7" colour screen, 4 GB Ram, 64 GB of storage and a more powerful 8 core processor. The colour is a bit underwhelming at first as it is washed out and there are only 4bits for each colour making a total palette of 4096 colours but you do get used to it after a few days use. Colour is of course not of really importance for the primary use of reading text. After using it for a few days and getting all my usual apps down and side loaded and home screen set up as I like I am quite pleased with this. Unlike the Poke 5 it is quite responsive to user gestures and the only app of my usual ones that won't work on it is Microsoft Swiftkey keyboard which Play Store thinks is incompatible for some reason so I am using Smart Keyboard Pro instead.
If anybody has any questions I would be pleased to answer them here.
