Android 中此警报消息框的含义
我正在 Android 中创建一个简单的应用程序。当我在模拟器中编译并运行它时,它会显示一个如下所示的警报框;它是什么意思?
抱歉,应用程序 simplegame(进程 com.example.simplegame)已意外停止。请重试!
我总是收到此警报框?请解释一下?
更新:
只是想在其中导入图片,
import android.app.Activity;
import android.os.Bundle;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.os.Handler;
public class SimpleGame extends Activity {
/** Called when the activity is first created. */
private Bitmap mBackGroundImage;
private Canvas canvas;
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
mBackGroundImage = hBitmapFactory(R.drawable.background1);
canvas.drawBitmap(mBackGroundImage, 0, 0,null);
setContentView(R.layout.main);
}
private Bitmap hBitmapFactory(int background1)
{
// TODO Auto-generated method stub
return null;
}
}
我对 android 很陌生。这就是为什么会遇到一些麻烦。
I am creating a simple application in Android. When I compile and run it in the emulator, it's showing an alert box like this; what it does mean?
sorry, The application simplegame (process com.example.simplegame) has stopped unexpectedly. Please try again!
I'm getting this alert box always? Please explain?

private Canvas canvas;
}
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
mBackGroundImage = hBitmapFactory(R.drawable.background1);
