java.lang.OutOfMemoryError照相机应用程序

我有一个问题，我已经搜索了几个星期，仍然没有解决方案。 此应用程序用于拍摄带有边框的照片。框架是PNG格式的

当我启动应用程序时，一切都很顺利，但当我点击按钮拍照时，应用程序崩溃了。有时它给出了OfMemoryError，有时是ArrayIndexOfBoundsException，所以我几乎什么都试过了，但什么都没试过。 我应该改变抽丝的尺寸吗？或者我应该设置最终bmp的大小

我为我的英语感到抱歉，因为我是法国人。。 这是密码

一个问题：解码字节数组（字节[]数据，整数偏移量，整数长度）

应该是（我不知道10的偏移量是多少，但你应该修正长度）

你试过调试你的代码吗？你知道是什么导致OutOfMemory错误吗？令人惊讶的是，有这么多人认为StackOverflow的用户喜欢免费调试其他人的代码。实际上，当我输入0时，我得到了内存错误，当我输入10时，我得到了另一个。。
