OpenglES in maplibre

[zjl114012]

If I want to use Opengles to render my own things onto the bottom map of the maplibre, how should I do it? Is there a simple example

Hi @zjl114012, please check out the custom layer functionality.

Work is underway to replace the OpenGL ES specific custom layer functionality with something platform-agnostic (that will work for both OpenGL ES and Metal) but for now this is what you should use if you want to render something with full control.

I am on the Android platform

Okay, I am compiling the mbgl test runner on Android devices for test, and I don't seem to see the shader code for Opengles in this section of the code

[zjl114012]

Sorry, I have been unable to compile mbgl test runner on Android devices with the following error. Besides, I have looked at the entire project and it seems that there is no code related to OpenGLES?
ERROR：
Could not create task ':app:processDebugResources'.
Cannot use @TaskAction annotation on method IncrementalTask.taskAction$gradle_core() because interface org.gradle.api.tasks.incremental.IncrementalTaskInputs is not a valid parameter to an action method.

Here are the relevant Android files that showcase how to use a custom layer.

maplibre-native/platform/android/src/example_custom_layer.cpp

Line 125 in 47028a6

class ExampleCustomLayer : mbgl::style::CustomLayerHost {

@zjl114012 Make sure you are using the Gradle wrapper, so you are using the correct Gradle version. That error is not releated to OpenGL ES.

I tried to compile MapboxGLAndroidSDKTestApp under Linux, but when using make android configuration in the root directory, the following error was displayed. I would like to ask if this is my own problem, or can you help me solve this problem.

I am trying to compile, and currently many versions are not compatible and are still being downloaded. May I ask if there is a simple use case like Getting Started.

[louwers]

You do not need to compile the library yourself as an end user, you can use the published library. There is a Getting Started guide for this here.

You can use this guide to get started with Android development of the library itself.
