Android的 - GLSurfaceView EGL_BAD_ALLOC [英] Android -- GLSurfaceView EGL_BAD_ALLOC

问题描述

在两个我的程序切换活动，每个充气派生 GLSurfaceView 使用维也纳各组织。经过来回切换这两个活动之间几次，程序崩溃并引发以下异常。每次有上下文切换VBO缓存被删除，的onStop（）被调用，而下一个活动的 GLSurfaceView 充气一个新的实例。我重构要运行的程序只有一个 GLSurfaceView 和活动，程序似乎没有发生任何事件运行。仅多边形和颜色的使用，无纹理。这里的损害：

My program switches between two Activities that each inflate a derived GLSurfaceView that uses VBOs. After switching back and forth between the two Activities a few times, the program crashes and throws the following exception. Each time there is a context switch the VBO buffers are deleted, onStop() is called, and a new instance of the next Activity's GLSurfaceView is inflated. I refactored the program to run on only one GLSurfaceView and Activity, and the program seems to run without incident. Only polygons and colors are used, no textures. Here's the damage:

Java.lang.RuntimeException: createContext failed: EGL_BAD_ALLOC
   at android.opengl.GLSurfaceView$EglHelper
      .throwEglException(GLSurfaceView.java:1079)
   at android.opengl.GLSurfaceView$EglHelper
      .throwEglException(GLSurfaceView.java:1071)
   at android.opengl.GLSurfaceView$EglHelper
      .start(GLSurfaceView.java:927)
   at android.opengl.GLSurfaceView$GLThread
      .guardedRun(GLSurfaceView.java:1248)
   at android.opengl.GLSurfaceView$GLThread
      .run(GLSurfaceView.java:1118)

从做一些互联网研究，这是一个公认的href="http://$c$c.google.com/p/android/issues/detail?id=16124">错误

From doing some internet research, this is a recognized bug. So how do I do damage control? +200 for a nudge in the right direction.

编辑：我解决了这个问题（我忘了打电话给在onPause（）/ ONRESTART（）在视图上）。第一个人把一个回答任何必然GETS +200。

I SOLVED THE PROBLEM (I FORGOT TO CALL ONPAUSE() / ONRESTART() ON THE VIEWS). FIRST PERSON TO PUT AN ANSWER ABOUT ANYTHING WHATSOEVER GETS +200.

推荐答案

烦人，我不能发表评论，但我想你的意思是onResume，不onRestart。您的活动可以被暂停，而不被停止，这会导致的onPause，但不是onRestart

Annoyingly I can't post a comment yet, but I think you mean onResume, not onRestart. Your Activity can be paused without being stopped, which would cause onPause, but not onRestart.

此图像（从活动文档）显示了该活动的生命周期非常漂亮：

This image (from the Activity docs) shows this activity life cycle very nicely:

总之，记住要传递的onPause和onResume到这两个超级给GLSurfaceView。

In short, remember to pass onPause and onResume to both your super and to the GLSurfaceView.

从<一个href="http://android-developers.blogspot.com/2009/04/introducing-glsurfaceview.html">http://android-developers.blogspot.com/2009/04/introducing-glsurfaceview.html:

public class ClearActivity extends Activity {
    ... snip ...

    @Override
    protected void onPause() {
        super.onPause();
        mGLView.onPause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        mGLView.onResume();
    }

    private GLSurfaceView mGLView;
}
