在MainActivity我导航playButton到PlayActivity然后我通过PlayActivity并且当i足够大时我去EndActivity但是我得到：

这可能与Canvas但不确定。

我通过以下方式开始 playActivity：

    playButton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Intent intent = new Intent(context, PlayActivity.class);
                startActivity(intent);          
            }

        });

playActivity 看起来像这样，我不知道我想纠正什么：

它说“E / dalvikvm-heap（15587）：14745616字节分配的内存不足。” 也许这是你的问题？看来您分配了太多位图资源。

这是一篇很好的文章。
