SurfaceView override.

[pazos]

in order to interact with the epd driver indirectly, via the View class framework, where the epd driver is hooked.

This is part of the solution proposed in koreader/koreader#3517 (comment) to add support for tolinos, but should be compatible with other devices based on the freescale platform.

All credits to @char11, thanks pal!

Things are working fine on the emulator/phone, but I lack a eink device to test.

Please @hugleo, @carlinux, @Cellaris (or anybody with a currently supported eink device) , could you test https://www.dropbox.com/s/froawrgv4jt6h1p/koreader-android-arm-linux-androideabi-debug-v2019.04-52-g7d742e15_2019-04-22.apk?dl=0 and report if eink updates still work?. Also extra points for the output of adb logcat -c && adb logcat KOReader:D *:S

Waiting for feedback before requesting reviews, and so on. If this build still works on Rockchip devices it will be wonderful 👍

Waiting for feedback before requesting reviews

Looks fine to me in any case. ;-)

[carlinux]

It works as intended
plus logcat

koreader.log

Edit: UUoops... i didn't check the install (failed). So it's the 386 build indeed.

I'll do it again with the ARM apk

[pazos]

Updated the apk for the right arch. Thanks for your help @carlinux, @hugleo.

To install this package you'll need to uninstall the one you have installed. It won't delete your settings, which are stored in /sdcard/koreader.

[hugleo]

Stuck in the update settings screen forever, clicked in the circle ball and crashed.

Can't open now, crash immediately.

Installing logcat in a minute...

Thanks for the log. It throws an error that seems unrelated to the changes in this PR, but I'm not sure. Pinging @Frenzie @NiLuJe

E KOReader: [main thread]: failed to run script: /data/user/0/org.koreader.launcher/files/reader.lua:178: attempt to call method 'setupDithering' (a nil value)
E KOReader: [main thread]: Stopping KOReader due to previous errors

[NiLuJe]

That's in ffi/framebuffer.lua, and ran from reader.lua behind a Device:hasEinkScreen() check. I have no idea why that would cause an issue on Android, but then again, I'm not familiar with how it's initalized there ;).

[NiLuJe]

Ah, the koreader asset package in the APK is not up-to-date, for some reason? (Well, it has a recent tag, and recent timestamps, but the content isn't up to date).

Is you base branch properly rebased, @pazos?

[pazos]

Is you base branch properly rebased, @pazos?

@NiLuJe nope, now I rebased and find a new build error

pazos@bowie:~/Escritorio/koreader$ ./kodev release --ignore-translation --debug android

Until now I worked w/ the sdk/ndk downloaded by KOReader but now it seems that I need to export the toolchain binpath. Is that intended?

[NiLuJe]

That's a warning we've caught on the CIs, too, it's apparently mostly harmless, though, but I'm not sure exactly where it's coming from.

The obvious guess would be shell CC calls in the makefile, but they should all be enforcing PATH now...

It more or less matches stupid warnings from CCache on other platforms, FWIW.

I can't reproduce any of it, but then I don't use ccache, and the compilers are always in my $PATH ;).

[pazos]

@NiLuJe: I finally got rid of the build error building on a clean tree.

@hugleo @carlinux: second round of tests!

Looks ok now.
Opened a book, followed some pages, refresh is working.

thanks for the feedback @hugleo.

Like I said, lgtm :-)
