我注意到谷歌应用商店中的其他益智游戏应用可以拥有多达400个可移动的拼图碎片。
我一直在尝试学习如何至少拍摄一张图片来代表我的拼图，裁剪某些部分并使用拼图设计掩盖剩余的图像空间，以创建我的个人拼图碎片。
我想让我的应用程序最多使用20个碎片，但是根据我的Android Studio内存日志，一旦位图工厂完成创建一个拼图碎片，我就会使用大约18MB的内存。在创建20个碎片以及应用程序的所有其他功能之后，我将使用超过400MB的内存，必须使用“largeHeap=true”来避免内存不足，但我非常接近超过这些更高的限制，使得应用程序非常缓慢并且足够的动画活动将不可避免地导致应用程序崩溃。
我很想知道那些其他应用程序在做什么，而我没有做到。
非常感谢任何建议。
FYI，我正在使用PNG24作为我的图像，并且测试图像的尺寸为556x720。
以下是一个例子，如果我只创建一个可动画的拼图碎片图像。
