Shader compilation crashes on Android emulators

[almithani]

After upgrading to react native 0.32 (from 0.26), I started to experience crashes on my Android emulator when displaying a map. I had been using Android SDK Tools 25.2.2, but downgraded to 25.1.7 and am now about to display the map successfully on my emulator.

Here's the relevant Android Monitor output:

                                                  uniform mat4 u_matrix;

                                                  }

This sounds like mapbox/mapbox-gl-native#5878.

Hi,

I'm experiencing the same... Has someone found a workaround to use while we get to a final solution?

Thanks!

[almithani]

@mgtitimoli My comment above mentions that downgrading Android SDK Tools worked for me. Did you try that?

[mgtitimoli]

thanks @almithani, no I haven't yet, it can't be done using the sdk manager, so I was looking for the link to download it manually... Which is your current setup, so I try with that one?

[almithani]

@mgtitimoli http://dl-ssl.google.com/android/repository/tools_r25.1.7-macosx.zip

[mgtitimoli]

(Thanks @almithani! Map is alive again...)

I can confirm this setup is working in case anyone is experiencing the same (there is no way to downgrade tools and platform tools, this is why I'm leaving all the links to download them manually and unzip it directly in your installation folder):

1. Android SDK version 24.4.1
   • this one is the entire SDK, I'm leaving it here in case you want to start from scratch, otherwise you can use what you already have and overwrite the specific folders with the packages specified below
2. Tools version 25.1.7
3. Platform Tools version 23.1.0
4. Android Support Repository (extras) version 38
   • this one goes under $ANDROID_HOME/extras/android
5. Available to download directly using SDK Manager (android sdk)

• Android SDK Build-tools version 23.0.3
• Android SDK Build-tools version 23.0.2
• Android SDK Build-tools version 23.0.1
• Android 6.0 (API 23)
  • SDK Platform version 23.3
  • Google APIs Intel x86 Atom_64 System Image version 23.16

Hope this issue gets resolved soon...

Now tracking upstream in mapbox/mapbox-gl-native#6400.

Try running the emulator with -gpu swiftshader, like this:
LD_PRELOAD='/usr/lib64/libstdc++.so.6' emulator -no-boot-anim -netdelay none -netspeed full -avd Nexus_5_API_22_x86 -gpu swiftshader -qemu -m 1526

The downgrade sadly don't worked for me ... it still crashes even the example app on emulator, bud on physical device it works ...
I only write here with working link to the platform tools 25 because the link by @mgtitimoli seems to be dead:
linux:
http://dl-ssl.google.com/android/repository/platform-tools_r25-linux.zip
windows:
http://dl-ssl.google.com/android/repository/platform-tools_r25-windows.zip
macos:
http://dl-ssl.google.com/android/repository/platform-tools_r25-macosx.zip

@uudruid74 Thanks so much for this! the '-gpu swiftshader' fixed a lot of crashes i've been getting. Much appreciated!
