i have tried unchecking library. i have uninstalled and re-installed, im using GLES2 so no jars, and the examples work just fine! so apparently there is a problem with my project itself..... have a look at some code:

package com.gmaninc.andegin;

import org.andengine.engine.camera.Camera;
import org.andengine.engine.options.EngineOptions;
import org.andengine.engine.options.ScreenOrientation;
import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.andengine.entity.scene.Scene;
import org.andengine.entity.scene.background.Background;
import org.andengine.entity.util.FPSLogger;
import org.andengine.opengl.font.FontFactory;
import org.andengine.ui.activity.BaseActivity;
import org.andengine.ui.activity.SimpleBaseGameActivity;

import android.graphics.Typeface;
import android.renderscript.Font;
public class Game extends SimpleBaseGameActivity {
    static final int CAMERA_WIDTH = 800;
    static final int CAMERA_HEIGHT = 480;

    public org.andengine.opengl.font.Font mFont;
    public Camera mCamera;

    //A reference to the current scene
    public Scene mCurrentScene;
    public static BaseActivity instance;
    @Override
    public EngineOptions onCreateEngineOptions() {
          instance = this;
            mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);

            return new EngineOptions(true, ScreenOrientation.LANDSCAPE_SENSOR, new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), mCamera);
    }
    @Override
    protected void onCreateResources() {
          mFont = FontFactory.create(this.getFontManager(),this.getTextureManager(), 256, 256,Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32);
            mFont.load();
    }
    @Override
    protected Scene onCreateScene() {
         mEngine.registerUpdateHandler(new FPSLogger());
            mCurrentScene = new Scene();
            mCurrentScene.setBackground(new Background(0.09804f, 0.7274f, 0.8f));
            return mCurrentScene;
            }
}

and my manifest

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

    </application>

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>


    <uses-permission android:name="android.permission.INTERNET"/>


</manifest>

there is only the one activity.... i have cleaned my project several times.... the problem as i see it, is the line in the logcat that says it cant find the baseclass of Game(SimpleBaseGameActivity)

like i said the examples are working fine.... so there must be somthing i missed in my project.... any help would be appreciatted!

p.s. please dont tell me to "uncheck library" or "clean the project" as i have tried these repeatedly

Answer 1

ok so i finally figured it out.... i had to update my sdk, and then go into eclipse>help>check for updates.... on a side note, i could not get SimpleBaseGameActivity to work so i am Using BaseGameActivity.... if you find your way here, and it still wont work, i recomend you check out the andengine tutorials on mybringback.com.... thats where i found the solution to several andengine problems i was having.
