Android Kitkat 4.4 with modified kernel

[Robson Pierangeli Godinho]

Hi all,
I build a Android Kitkat 4.4 and I modify the kernel to accept a new touchscreen. So, after compiling Android and generate ISO, I install on my X86 terminal but some apps not worked. The browser, galery and Play Store stops with message "Unfortunately <app> has stopped".

Can someone help?

Thanks in advance,

Robson

Please provide a patch for the new touchscreen driver.

Check logcat to see what happened.

I'm not 100% sure this can solve your problem, but when compiling a completely new kernel,

usually the three libwebchromium folders in $OUT/target/product/x86/obj/SHARED_LIBRARIES/ need to be deleted.

Could you enable DEBUG at boot and post here  /data/log.txt and dmesg output?

Hello Chih-Wei,

     Despite the My Experience with Linux , I am beginner to x86 Android. The browser made ​​the following errors in your startup:

I/ActivityManager( 1710): Start proc com.android.browser for activity com.android.browser/.BrowserActivity: pid=2600 uid=10020 gids={50020, 3003, 1028, 1015, 1023}

My Android file system is in /storage/sdcard0/ and is writable.

There is a config that I can make to change browser dir?

Thanks

Hi Chih-Wei,
Thanks for the reply , I found the problem. Applications that are stopping are based on the OpenGL ES that is not implemented in Android x86. Then I'll need help to make it work , can you help me? I'm doing a version for the Unicorn D2550 board with a resistive touch screen of 1024x600 (eGalax Touch).

About the touchscreen, I had to change the kernel for it to work. I installed the driver from the manufacturer (http://www.eeti.com.tw/drivers_Linux.html) and changed the kernel according to the manufacturer instructions. If you want, I can send the modified code files to the kernel.

Thank you

Robson

Hi Mauro,

     I did what you suggested and now I saw that my Android is "broken".

     Follow the 3 logs:

log_init.txt : dmesg log before Android initialize

log.txt: dmesg log after Android initialize

log_data.txt: the log of dir data.

Thank you 

Robson

I never see such an issue in libwebviewchromium.so.
Don't think it's related to kernel.
Maybe your build environment is broken?

Since you only care the kernel,
the simplest way is just replace the kernel and modules
by the files you made in the 4.4-r3 image.

Hi Robson,

can you also check how you have integrated Gapps in your build?

Have you used the gapps.sh script (provided in this forum) in conjunction with an ISO already with gapps, method which is failsafe?

Hi Mauro/Chih-Wei,

     I found the problem, Gallery and Google Play uses OpenGL ES that is not implemented. UVesafb not support this feature.

     Now I'm looking for a driver to Unicorn D2550 that uses a Intel GMA 3650 engine.

     When I find a solution, I'll post here.

Thanks

Robson

Oh, if that's the root cause, the log should not be
related to libwebviewchromium.so but something else,
I think.

Anyway, if it's GMA 3650, you're right
that it's not supported since it's
a PowerVR based chip.

You'll find you are unlucky since
it's not possible at this moment.
Anyway, it's no harm for you to
try and learn.
