这是关于屏幕移动的程序：

    public Engine onLoadEngine() {
        mHandler=new Handler();
        mHandler.removeCallbacks(mLaunchTask);
        this.mCamera = new Camera(0, 0, CAMERA_WIDTH,CAMERA_HEIGHT);
        return new Engine(
            new EngineOptions(
                true,
                ScreenOrientation.LANDSCAPE,
                new RatioResolutionPolicy(CAMERA_WIDTH,CAMERA_HEIGHT),
                this.mCamera
            )
        );
    }
    @Override
    public void onLoadResources() {
        mBitmapTextureAtlas = new BitmapTextureAtlas(512, 512,TextureOptions.BILINEAR_PREMULTIPLYALPHA);
        mSplashTextureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(
            this.mBitmapTextureAtlas, this, "Splashscreen.png", 0, 0
        );
        this.mEngine.getTextureManager().loadTexture(this.mBitmapTextureAtlas);
    }
    @Override
    public Scene onLoadScene() {
        this.mEngine.registerUpdateHandler(new FPSLogger());
        final Scene scene = new Scene(1);
        /* Center the splash on the camera. */
        final int centerX =(CAMERA_WIDTH - this.mSplashTextureRegion.getWidth()) / 2;
        final int centerY =(CAMERA_HEIGHT -this.mSplashTextureRegion.getHeight()) / 2;
        /* Create the sprite and add it to the scene. */
        final Sprite splash = new Sprite(centerX,centerY, this.mSplashTextureRegion);
        scene.getLastChild().attachChild(splash);
        return scene;
    }
    @Override
    public void onLoadComplete() {
        mHandler.postDelayed(mLaunchTask, 3000);
    }

    private Runnable mLaunchTask=new Runnable(){
        public void run(){

            Intent mIntent=new Intent(StartActivity.this, MainMenuActivity.class);
            StartActivity.this.startActivity(mIntent);
        }
    };
}

修改后这是我的清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pearson.lagp.v3"
    android:versionCode="1"

        </activity>
        <activity 
            android:name="com.pearson.lagp.v3.MainMenuActivity"
            android:label="@string/menu_name">
        </activity>
    </application>

</manifest>

为什么它崩溃了？

Answer 1

您是否在清单中声明了您的活动？

或

使用正确的包名检查您在清单上的活动？

Android OnClick error

Unable to find explicit activity class and unable to instantiate activity

Answer 2

试试这个..你的活动应该在清单

中像这样被涂抹

    android:name="com.example.namespace.Firstactivity"

清单中的

（或）意图过滤器声明在错误的位置。重命名您的活动名称并发布您的清单。
