android - eglMakeCurrent() 失败 EGL_BAD_ALLOC

Question

我不断收到此错误报告:

Fatal Exception: java.lang.IllegalStateException
eglMakeCurrent failed EGL_BAD_ALLOC
android.view.HardwareRenderer$GlRenderer.createSurface

...在我在 Play 商店中的应用上。

是什么导致了这个崩溃以及如何修复它？

以下是完整的错误日志:

如果您查看 EGL specification , 这个错误有几个可能的原因。您的应用程序中的某些东西似乎导致其资源不足。规范声明如下:

3.7.3 Binding Contexts and Drawables

... eglMakeCurrent binds ctx to the current rendering thread and to the draw and read surfaces...

Errors

... If the ancillary buffers for draw and read cannot be allocated, an EGL_BAD_ALLOC error is generated...

要解决此问题，您可以检查应用程序的内存使用情况。有许多不同的技术可以调查您的应用程序的 ram 使用情况，some techniques are documented quite well in this guide.

This post还描述了调用eglMakeCurrent时如果调用eglCreatePbufferSurface时没有设置像素缓冲区的EGL_WIDTH和EGL_HEIGHT参数会触发错误。这是创建像素缓冲区的最小 Java 示例 (full source located here) ,确保输入的宽高大于零:

private void eglSetup(int width, int height) {
    mEGL = (EGL10)EGLContext.getEGL();
    mEGLDisplay = mEGL.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
    if (!mEGL.eglInitialize(mEGLDisplay, null)) {
        throw new RuntimeException("unable to initialize EGL10");
    }

    // Configure EGL for pbuffer and OpenGL ES 2.0.  We want enough RGB bits
    // to be able to tell if the frame is reasonable.
    int[] attribList = {
            EGL10.EGL_RED_SIZE, 8,
            EGL10.EGL_GREEN_SIZE, 8,
            EGL10.EGL_BLUE_SIZE, 8,
            EGL10.EGL_SURFACE_TYPE, EGL10.EGL_PBUFFER_BIT,
            EGL10.EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
            EGL10.EGL_NONE
    };
    EGLConfig[] configs = new EGLConfig[1];
    int[] numConfigs = new int[1];
    if (!mEGL.eglChooseConfig(mEGLDisplay, attribList, configs, 1, numConfigs)) {
        throw new RuntimeException("unable to find RGB888+pbuffer EGL config");
    }

    // Configure context for OpenGL ES 2.0.
    int[] attrib_list = {
            EGL14.EGL_CONTEXT_CLIENT_VERSION, 2,
            EGL10.EGL_NONE
    };
    mEGLContext = mEGL.eglCreateContext(mEGLDisplay, configs[0], EGL10.EGL_NO_CONTEXT,
        attrib_list);
    checkEglError("eglCreateContext");
    if (mEGLContext == null) {
        throw new RuntimeException("null context");
    }

    // Create a pbuffer surface.  By using this for output, we can use glReadPixels
    // to test values in the output.
    int[] surfaceAttribs = {
            EGL10.EGL_WIDTH, width,
            EGL10.EGL_HEIGHT, height,
            EGL10.EGL_NONE
    };
    mEGLSurface = mEGL.eglCreatePbufferSurface(mEGLDisplay, configs[0], surfaceAttribs);
    checkEglError("eglCreatePbufferSurface");
    if (mEGLSurface == null) {
        throw new RuntimeException("surface was null");
    }

    mEGL.eglMakeCurrent(mEGLDisplay, mEGLSurface, mEGLSurface, mEGLContext);
}

如果不了解应用程序实现的更多细节，就很难确定确切的原因。这应该是识别和解决问题的良好起点。
