Description Joe LeVeque 2013-08-12 12:28:39 UTC 
After starting up the on-screen keyboard in Android, events are received for all character keys, but no events are received for the Backspace or Enter/Return keys. I have set a breakpoint in my event loop and proven that I receive no events whatsoever for Backspace or Enter/Return.

I just verified and I get SDL_KEYUP / SDL_KEYDOWN events with keycode 8 (BACKSPACE) and 13 (ENTER), and SDL_TEXTINPUT events for regular characters. Is this the way it's supposed to work?

On 8/20 I updated my source to the latest hg snapshot, and I noticed that the ENTER key was now having an effect in my app (but not BACKSPACE), so I went to debug my app to see what events were now being received, but unfortunately I had also just updated my device to Android 4.3, in which I found that Google has included a beautiful bug that completely breaks native code debugging (see the bug report here: https://code.google.com/p/android/issues/detail?id=58373). I'm waiting for a fix from Google and in the meantime trying to find a workaround so I can debug my app again. :(

What happened to good old __android_log_print ? :)

That's actually what I did to test this, on the key up, down and text input events, I added a print command to see what's arriving from the keyboard. And that seemed to work (I'm also on Android 4.3)
Comment 4 Joe LeVeque 2013-08-22 17:29:01 UTC 
OK - you got me ;) I've been busy with other things, and I also need to get the debugger working for other issues, so I did kinda put this issue on the back burner. Anyway, I added an __android_log_print, and I verified that I am now receiving SDL_KEYUP / SDL_KEYDOWN events for ENTER, but still no event at all for BACKSPACE. However, I am seeing a new message in the logcat whenever BACKSPACE is pressed:

08-22 12:23:26.451: E/LatinIME(1259): Backspace when we don't know the selection position

Again, I am running SDL from changeset 7659.

For reference: http://forum.unity3d.com/threads/161471-Backspace-key-of-screen-keyboard-not-work

I'm using Swiftkey which probably explains why I'm not seeing the problem.

Gabriel - good find! At least I know I'm not crazy! It's good to know other people are looking into this as well, but it seems like a pretty nasty issue. Here's hoping there's a simple solution.

FYI, Looks like this might be a possible explanation/solution:

Should be fixed now, thanks for the research! https://hg.libsdl.org/SDL/rev/b8f431cd7819
