[Q] About build image from sdk

Hi!
I'm using haret to try a android version in a device.
I'd like add debug information to the images os.
What is the method to go from sources (android sdk) to image os?
I have, in haret, this archives:
Kernel: zImage
Initrd: initrd.gz
Os files: androidinstall.tar
I'd like rebuilt it from the sources. They are the android from repo of google?
TIA

[CM 10.2] linux headers for building a kernel module?

I'm trying to compile a kernel module for Cyanogenmod 10.2.1 on a Nexus 7 tablet (tilapia). I'm using for this task an ARM virtual machine with Debian installed on it.
To compile the module I need the CM linux headers, but I can't find where to get them. Can you please link me the source repo?
PS: I want to compile a driver for a usb to lan adapter:

You don't need "cm linux" headers. There is no such thing. What you need is to compile from source the kernel you are using....which is some 3.1.10 kernel. Then you need to have the "3.1.10 kernel headers" installed. Finally you cross compile the USB to Lan driver against the sources of the kernel you compiled. If the compiled kernel is there....then the cross compiler must be properly linked to the source...and it will find the header files it needs and warn you of missing dependencies. It could be that you'll need to enable some things in the kernel build in order to have all the needed support for your driver.

android emulate failed using AOSP source

Hi, I downloaded android full sources 5.1, 6.0, 7.0 and i built them.
I tried to check operating using the android emulator in sdk, but it failed except 5.1.
I replaced original image file( system.img, ramdisk.img, userdata.img) to new built files. And then I run. But I can't see android logo and it didn't progress.
I chose mini-emulator-arm-debug and original emulator image same to version and AOSP.
I didn't know why android 5.1 is operated but android 6.0 and 7.0 didn't do it. Has the method of execution changed?
So please help me.
1. The source build is succeeded.
2.Emulator screen showed only black. I tried to connect using adb shell but failed.

How to port libs to Android x86

Hi! Take a look at this situation: I have an Android x86 tablet (model Multilaser M7i Nb190) Intel, Android 4.4, but the internal emmc memory i'snt working anymore, but the rest of the device still 'works', Generic Android x86 boot up, even Ubuntu n' ZorinOS Lite, but I can go after setup screen because there's no touchscreen support for my device, I have the original rom, but the structure of the device rom and of the Android x86.iso seems to be different. How to port the device drivers (libs) to the Android x86 generic.iso rom? I have version of Android x86 4.4, its better to use it because it is the same version of the device rom (in general)? Thanks for any help. ... And why xda app still giving network error after trying to upload an image?!

Android Stagefright on x86 Linux
Trying to build Stagefright (cmd line tool) on x86 Managed to build it to decode audio files, however with Video I have this problem. It seems to want to open libstagefright_ccodec.so, but I cannot...
stackoverflow.com
Can somebody help to build it?
Thanks,

The library was removed from AOSP with https://android.googlesource.com/pl...av/+/469bd61ba3f8e56697f433b64ca724001cdafad7

Thank you. Weird is that I built:
6780336android-9.0.0_r61Pie2018-08-05
And it wasn't there (build before deletion).
How to active it? Any ideas?
Why on Android Emulator it does not load it and on x86 Laptop it looks for it?
I will also try to build:
android-11.0.0_r35
So hopefully it will work and don't need this lib.
