在调试Android应用时，遇到虚拟机不定时自动断开的情况，原因是数组元素初始化不完全导致。解决方案是确保所有数组元素都进行正确的初始化，避免引发异常。通过对stick_images数组的所有元素赋值，成功解决了断开连接的问题。

Debug时遇到的问题：

设置断点后debug时不定时出现自动断开虚拟机连接，debug窗口提示以下信息

<terminated>MAME4droid [Android Application]

<disconnected>DalvikVM [localhost:8615]

但logcat窗口无任何异常提示。

原因：数组元素初始化赋值时没有全部初始化或者初始化值不正确，导致后续使用异常。如

static BitmapDrawable stick_images[] = null;

stick_images = new BitmapDrawable[9];

            stick_images[InputHandler.STICK_DOWN] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down);
           stick_images[InputHandler.STICK_DOWN_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down_left);
           stick_images[InputHandler.STICK_DOWN_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down_right);
           stick_images[InputHandler.STICK_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_left);
//          stick_images[InputHandler.STICK_NONE] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_none);
           stick_images[InputHandler.STICK_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_right);
           stick_images[InputHandler.STICK_UP] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up);
           stick_images[InputHandler.STICK_UP_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up_left);
           stick_images[InputHandler.STICK_UP_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up_right);

解决方案：初始化完成每个数组元素。如

            stick_images[InputHandler.STICK_DOWN] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down);
           stick_images[InputHandler.STICK_DOWN_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down_left);
           stick_images[InputHandler.STICK_DOWN_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_down_right);
           stick_images[InputHandler.STICK_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_left);
            stick_images[InputHandler.STICK_NONE] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_none);
           stick_images[InputHandler.STICK_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_right);
           stick_images[InputHandler.STICK_UP] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up);
           stick_images[InputHandler.STICK_UP_LEFT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up_left);
           stick_images[InputHandler.STICK_UP_RIGHT] = (BitmapDrawable)mm.getResources().getDrawable(R.drawable.stick_up_right);
