Shader failed to compile: ERROR: Valid GLSL but not GLSL ES

[ivovandongen]

The shaders won't compile on the android emulators anymore, resulting in crashes of all maps.

This can be fixed by changing your emulated graphics to Software - GLES 2.0 in your AVD settings. This is not ideal, but it will work (and is still much faster than emulating an ARM device).

I suspect this is emulator specific.

@ivovandongen any updates on this?

[ivovandongen]

@masterjefferson I just retested this with updates to Android Studio and I don't see the issue anymore. Can you verify?

[ivovandongen]

Just tried to verify this. It worked for me on Android Studio 2.1.3, but not on 2.2-rc2.

[zugaldia]

Just confirming @ivovandongen 's finding, not getting the crash on Studio 2.1.3.

[ivovandongen]

Thanks @zugaldia. I'm closing this one now than as it seems to be related to the emulators in the upcoming Android Studio release.

[jeffypooo]

@ivovandongen @zugaldia Thanks for the info

This exists in 2.1.3 now with SDK Tools and Build tools upgrade. After upgrade, I have the following versions installed:

SDK Tools: 25.2.2
Platform-tools: 24.0.3
Build-tools: 24.0.2

I did not change anything in the project. It still uses:

minSdkVersion = 18
compileSdkVersion = 23
targetSdkVersion  = 23
buildToolsVersion = "23.0.3"

But mapbox is now broken in all emulators.

[jeffypooo]

Problem still persists in AS 2.2

SDK Tools: 25.2.2
Platform-tools: 24.0.3
Build-tools: 24.0.2

I'm leaving here a setup that works in case anyone decides to rollback the upgrade while we wait for the fix...
