编辑:背景图像代码

BitmapFactory.Options options = new BitmapFactory.Options();//Line 156
options.inSampleSize = 2;    // this will cut the sampling by 50%//Line 157
mBackground = BitmapFactory.decodeResource(getResources(),R.drawable.background, options );//Line 158

EDIT2:图像的构造函数

public HitmanThread(SurfaceHolder surfaceHolder, Context context, Handler handler ) {
this.mSurfaceHolder = surfaceHolder;
mHandler = handler;
mContext = context;
mRes = context.getResources();      

paint.setColor(Color.BLACK);

paint.setTextSize(16);

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;    // this will cut the sampling by 50%
mBackground = BitmapFactory.decodeResource(getResources(),R.drawable.background, options );
    }

编辑3:

我尝试在一些使用 2.2 及更高版本的较新手机上运行我的游戏。它之所以有效，是因为在不崩溃的情况下，无论如何都可以指定一定的虚拟机预算。遗憾的是，任何 16mb 或更少的东西都无法运行。我有 3.4mb 的堆和 1mb 的空闲空间，任何替代解决方案将不胜感激。

让我们从底部开始......

我想在文件 HitmanView.java 的第 158 行中，您正在尝试加载一个大得令人发指的位图？
