# I've found that the "Migrate to AndroidX" converter in Android Studio doesn't work very
# well, so I wrote my own script to do the simple job of converting package names.
#
# You can download a CSV of package names here: https://developer.android.com/topic/libraries/support-library/downloads/androidx-class-mapping.csv
#
# It'll run faster on a clean build because then there are fewer files to scan over.
#
# Uses `gsed` because I'm on a Mac. Can easily replace with `sed` if you don't have `gsed`.

1. The texture target needs to be GLES20.GL_TEXTURE_EXTERNAL_OES instead of GL_TEXTURE_2D, e.g. in the glBindTexture calls and glTexParameteri calls.

2. In the fragment shader define a requirement to use the extension:
#extension GL_OES_EGL_image_external : require

3. For the texture sampler used in the fragment shader, use samplerExternalOES instead of sampler2D.

Everything below here is all in the C code, no more Java.

4. In the C code, use glEGLImageTargetTexture2DOES(GL_TEXTURE_EXTERNAL_OES, eglImage) to specify where the data is, instead of using glTexImage2D family of functions.

    // we don't want to corrupt the data we send
    @error_reporting(0);

    // Make sure the files exists, otherwise we are wasting our time
    if (!file_exists($file)) {
      header("HTTP/1.1 404 Not Found");
      exit;

Building ROMs with microG integrated

---

Intro

I never thought I'd do this instead of just build normal ROMs and install microG manually just like people flashes opengapps or some other stuff, but then I found out that "LineageOS for microG" exists, stable custom ROM plus microG instead of bs out of box, nice idea isn't it?

If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:

echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

I suggest you edit your /etc/rc.local file to make this change persistant across reboots.

sudo nano /etc/rc.local

Hello A5 And A7 2017 community. :)
This makes the sources I was using to create LineageOS builds for our devices free, open and available for everyone.
Feel free to use this to create personal builds or update the community with newer security patches or small improvements.
Feel free to also use this as a base for creating other third party roms that are not necessarily LineageOS.
However please note that I have spent a lot of my personal time on this project.
And so did numerous other people from LineageOS team and Samsung exynos developer community.
I would only like to kindly request to give proper credits where due.
Thanks

These sources are for building LineageOS 21 before QPR2 merge occured.
