大佬教程收集整理的这篇文章主要介绍了android – outofmemoryerror同时制作位图，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我想将图像保存在onPictureTaken回调中
我的消息来源如下
public void onPictureTaken(byte[] data,Camera camera) { //preview from camera Bitmap bitmap = BitmapFactory.decodeByteArray(data,data.length); // overlay image Bitmap overlayBmp = overlay.getDrawingCache(); //blank beatmap Bitmap blankBitmap = Bitmap.createBitmap(bitmap.getWidth(),bitmap.getHeight(),Bitmap.Config.ARGB_8888); //make canvas Canvas canvas = new Canvas(blankBitmap); //composite image canvas.drawBitmap(bitmap,null,new Rect(0,bitmap.getWidth(),bitmap.getHeight()),null); canvas.drawBitmap(overlayBmp,null);
然而,它显示了outofmemoryerrorrror,我怎么能解决这个问题..？

在位图中获取图像,然后根据您的要求使用.
