android - How to avoid "outofmemory" when download image in gridview? -

I have tried to show a lot of images in Gridview. There are two activities. Both of them have gridviews whose pictures are when I start only one of them. There are no questions, but when I start the second, then the problem of "out problem" occurs PS: To use this stackoverflow is my first and my english is me poor.forgive ~ ~

 < Code> Public category HeroGridAdapter extends the BaseAdapter {Personal context mContext ;.

 I think it can help you  < P> And there is a pretty good sample that you can do on developer.android.com which handles all bitmap memory.
