(LibGDX) Android 应用程序在创建 FrameBuffers 时崩溃

Question

我从 Google Play 商店收到了我的 Android 使用 LibGDX 创建的应用程序的崩溃报告。

Huawei MediaPad T3 7 (hwbg2), Android 6.0

java.lang.IllegalStateException:
  at com.badlogic.gdx.graphics.glutils.GLFrameBuffer.build (GLFrameBuffer.java:233)

代码位于 GLFrameBuffer.java:233

if (result == GL20.GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT)
            throw new IllegalStateException("frame buffer couldn't be constructed: incomplete attachment");

EditingImage.java如下

class EditingImage{

    public static final int pixmapWidth = 1024;

    public EditingImage{
        frameBuffer = FrameBuffer.createFrameBuffer(Pixmap.Format.RGB888,pixmapWidth,pixmapWidth,false);

        ....

        for (int i = 0; i < 50; i++){
          final Backup backup = new Backup(pixmapWidth);
          availableBackups.add(backup);
        }
    }
}

Backup.java如下

Backup(int width){
    frameBuffer = FrameBuffer.createFrameBuffer(Pixmap.Format.RGB888, width, width, false);
    ....
}

应用程序在创建 FrameBuffer 时在 Backup.java 内崩溃（我不知道循环了多少次）。

正如你所见，在EditingImage中创建的FrameBuffer并没有崩溃，它已经在实例化Backup对象之前执行了。

在我的phone（华为Y6II）上正常。也已经在一些三星 phones.

测试过

请帮忙！

1 年 11 个月后我发现了问题。

根据文档：

https://libgdx.badlogicgames.com/ci/nightlies/docs/api/com/badlogic/gdx/graphics/glutils/FrameBuffer.html

它表示在构造函数中作为参数传递的格式应该是 RGB565 或 RGBA4444 或 RGB5_A1

format - the format of the color buffer; according to the OpenGL ES 2.0 spec, only RGB565, RGBA4444 and RGB5_A1 are color-renderable

在我的例子中，我使用了 RGB888
