我注意到来自 google play 商店的其他拼图应用程序可以多达 400 个单独的可移动拼图
我一直在尝试学习如何至少拍摄一张能代表我的拼图的图像,裁剪某些部分并用拼图设计掩盖留下的图像空间,以创建我的个人拼图
我想为我的应用程序最多使用 20 块,但到目前为止,根据我的 android studio 内存日志,一旦位图工厂完成创建一个拼图块,我正在使用大约 18mb 的内存,在与所有其他块一起创建 20 块之后应用程序的功能我使用了 400+mb 的内存,我必须使用“largeHeap=true”来避免内存不足,但我已经接近超过这些更高的限制,以至于应用程序超级缓慢且足够动画活动将不可避免地使应用程序崩溃
我很想知道其他 Play Store 益智应用在做什么,而我没有
非常感谢任何输入
仅供参考,我的图像使用 PNG24,测试图像的尺寸为 556x720
这是一个示例,如果我只创建一个动画拼图图像
