setContentView crashes android emulator

问题


I am going through the android tutorials on how to use graphics and animations. When I set my new content view the application crashes. I looked up the problem here and saw people with similar problems with this tutorial, but none of the solutions I have found have worked for me. I know people said the order of the lines when you set up your renderer is important but I have it in the same order they said to use. When I run in debug it seems to crash in the middle of the call to setContentView (which I can't see into, eclipse just says sorce not found at this part since I didn't write it).

Here is my main activity file: package com.example.graphicsretry;

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

public class MainActivity extends Activity {

    private GLSurfaceView mGLView;

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

        mGLView = new MyGLSurfaceView(this);
        /*mGLView = new GLSurfaceView(this);
        mGLView.setEGLContextClientVersion(2);
        MyGL20Renderer mg = new MyGL20Renderer();
        mGLView.setRenderer(mg);*/
        setContentView(mGLView);
    }

}

class MyGLSurfaceView extends GLSurfaceView {

    public MyGLSurfaceView(Context context){
        super(context);
        setEGLContextClientVersion(2);
        MyGL20Renderer mg = new MyGL20Renderer();
        setRenderer(mg);
        setRenderMode(GLSurfaceView.RENDERMODE_WHEN_DIRTY);
    }
}

This is my renderer class

package com.example.graphicsretry;
import android.opengl.GLSurfaceView;
import javax.microedition.khronos.opengles.GL10;
import android.opengl.GLES20;
import javax.microedition.khronos.egl.EGLConfig;

public class MyGL20Renderer implements GLSurfaceView.Renderer {

    public void onSurfaceCreated(GL10 unused, EGLConfig config) {
        // Set the background frame color
        GLES20.glClearColor(0.5f, 0.5f, 0.5f, 1.0f);
    }

    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);
    }
}

Here is my android manifest file. It has the uses-feature tag needed and two support texture tags (NOTE: I tried it without the support texture tags and it still crashed):

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <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.graphicsretry.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>

I pasted my logcat file here in case it helps anyone: http://pastebin.com/EvB9NYJF
