developer.android.com OpenGL es示例不起作用？

Question

我正在关注本教程：http://developer.android.com/training/graphics/opengl/environment.html

并尝试让它在一整天内运行......与此同时，我正在研究其他一些关于OpenGL的教程，但最后我总是遇到应用程序崩溃... 这是我的所有文件： 的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.openglproject1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <uses-feature android:glEsVersion="0x00020000" android:required="true" />
    <supports-gl-texture android:name="GL_OES_compressed_ETC1_RGB8_texture" />
    <supports-gl-texture android:name="GL_OES_compressed_paletted_texture" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.openglproject1.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

activity_main.xml中：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.openglproject1.MainActivity"
    tools:ignore="MergeRootFrame" />

fragment_main.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

</LinearLayout>

MainActivity.java：

package com.example.openglproject1;

import android.app.Activity;
import android.content.Context;
import android.opengl.GLSurfaceView;
import android.os.Bundle;

public class MainActivity extends Activity {

    private GLSurfaceView mGLView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Create a GLSurfaceView instance and set it
        // as the ContentView for this Activity.
        mGLView = new MyGLSurfaceView(this);
        setContentView(mGLView);
    }

    class MyGLSurfaceView extends GLSurfaceView {

        public MyGLSurfaceView(Context context){
            super(context);

         // Create an OpenGL ES 2.0 context
            setEGLContextClientVersion(2);
            // Set the Renderer for drawing on the GLSurfaceView
            setRenderer(new MyGLRenderer());
         // Render the view only when there is a change in the drawing data
            setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
        }
    }

}

MyGLRenderer.java：

package com.example.openglproject1;

import javax.microedition.khronos.egl.EGLConfig;
import javax.microedition.khronos.opengles.GL10;

import android.opengl.GLSurfaceView;
import android.opengl.GLES20;

public class MyGLRenderer implements GLSurfaceView.Renderer {

    public void onDrawFrame(GL10 unused) {
        // Redraw background color
        GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
    }

    public void onSurfaceChanged(GL10 unused, int width, int height) {
        GLES20.glViewport(0, 0, width, height);
    }

    @Override
    public void onSurfaceCreated(GL10 arg0, EGLConfig arg1) {
        GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f);

    }
}

根据developer.android.com，这应该工作并显示灰色屏幕。我能够编译应用程序并在模拟器上启动它但它会立即崩溃...有没有人在这些代码片段中看到任何问题？我已经厌倦了尝试一整天运行1个愚蠢的OpenGL应用程序...... 这是logcat：
