I’ve created an app with a number of ‘books’, each broken into chapters using \c markers. The ToC then points to different chapters.
The problem comes which navigating from one chapter to the next by swiping. The app is RTL and swiping left to right correctly advances us to the next chapter. However swiping right to left does NOT make us go to the preceding chapter… it does nothing.
Is this a bug in RAB? Is it possible it’s something I just set up wrong in my files?
Some how I missed this.
Can you share your APK file and your whole project for us to test?
If you share on DropBox or Google drive, let me know the link by personal message.
I was able to download the apk and the project.
None worked on my emulator, but the app I built worked on my phone.
Swiping right to left worked. Is there something else you are doing first before the swipe RTL stops working. If we can’t find a way to make it always happen then it is unlikely to get fixed.
Ian,
This took me down a rabbithole of testing. I was originally happy to hear your reply and thought that maybe the problem was just my phone. Sadly that doesn’t appear to be the case, and the problem appears to plague any RAB or SAB app I build. I’m interested in testing builds from other people, particularly in RTL languages. Did you say that you built the app? If so, could you send me the arm64 version you created?
If your version works, then I might ask you to send me your sdk folder so that I can test using it. I had a horrible time getting the Android sdk to work correctly, so I’m not 100% confident my build is good.
It’s not that RTL swiping sometimes works–it never does. LTR moves to the next chapter, but RTL swiping doesn’t move to the previous one.
What I’ve discovered.
Works:
Amazon Fire HD 8 2020 (stock rom; arm)
One of team member’s phone. I don’t know details other than it is arm64
Doesn’t work:
Moto g7 Plus (running Android 11 via LineageOS; arm64)
Moto g8 Plus (running Android 10 via stock rom; arm64)
Moto Droid Turbo (running Android 9 via LineageOS; arm)
Android Studio emulator, Android 10, x86

I’m re-raising this issue because I believe it’s truly a bug (and continues to cause our projects to not work correctly).
In particular, this appears directly related to enabling Crosswalk viewer. In this minimal working example, the app works correctly on the phone when Crosswalk isn’t enabled (you can swipe left and right between chapters), but when Crosswalk is enabled it stops working. In particular, if you are in Chapter 2 then you can swipe back to Chapter 1, but once you’re in Chapter 1 you can’t swipe to Chapter 2.
I just tested this with Crosswalk enabled and I could still swipe between chapters.
Could you send me the apk (arm64)? That will help me figure out if the problem is on my RAB setup or on the phones.
As I used your project, that seems ok. I’ll send a link to the APK in a private message.
Using your apk, I found mixed results just like I had before:
Works correctly:
Moto g5, Android 8.1.0, stock rom
Amazon Fire Tablet
Android Studio, Pixel 4, API 29
Only swipes in one direction:
OnePlus 6t, Android 11, stock rom (OxygenOS 11.1.2.2)
Moto g8 Plus, Android 10, stock rom
Windows Subsystem for Android
Android Studio, Pixel 4 XL, API 28 and also API 29
I found the final results quite odd. In the same emulator (the one built into Android Studio), I was getting different results based on which phone I chose.
I have written this up.
On my Android 11 phone that I had not tested on, The contents menu did not load at all. Removing the contents menu, the chapter 1 page did not load. That is very weird, So I could not even attempt to do the swipe test.
Thank you for looking in to this.
