内存不足的错误即使COM pressing图像 [英] Out of memory error even after compressing the image

问题描述

下面是我的code请检查并解决我的问题。
在此IM通过图像路径获得的图像也就是我正在以 selectimage1 ， selectimage2 ...的推移和从那以后，我已经拍摄的图像中的位图，然后去code和减小其尺寸巢穴也越来越内存不足的错误。

所以，请帮我把它弄出来。

感谢

解决方案

尝试缩小位图，而不是COM $ P $的pssing它。 Android官方网站有这样一个非常详细的指导： http://developer.android.com/培训/显示的位图/

Here is my code please check and resolve my problem . In this i m getting image through image path i.e. i'm taking that in selectimage1, selectimage2...goes on and after that i have taken the image in Bitmap and then decode and reduce its size den also getting out of memory error .

so please help me to get out of it.

thanks

解决方案

Try scaling down the Bitmap instead of compressing it. The official Android website has a very detailed guide for this: http://developer.android.com/training/displaying-bitmaps/
