ImageLoader- java.lang.OutOfMemoryError

建议：Android官方给的建议是，作为程序员的我们应该努力减少内存的使用，想回收和复用的方法，而不是想方设法增大内存。当内存很大的时候，每次gc的时间也会长一些，性能会下降呦。

I developing an android app that requires me to display some images by getting it from the server at the run_time, so I get it's thumbnail and then use Android-Universal-ImageLoader to get these images:

   ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()).build();
   ImageLoader.getInstance().init(config);

      // to get the movie_poster from the server
        private void setImageResource_season(ImageButton image, String url){

            loader = ImageLoader.getInstance();
            loader.displayImage(url, image);

        }

when it's a little amount of images everything goes well, but when it's like about 100 images the ImageLoader gives me likefrom10 to 15 images then it passes me that exception:

我开发Android应用程序，我需要让它从服务器在run_time展示一些图片，所以我得到它的缩略图然后使用Android的通用imageloader为了得到这些图像：

   ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext()).build();
   ImageLoader.getInstance().init(config);

      // to get the movie_poster from the server
        private void setImageResource_season(ImageButton image, String url){

            loader = ImageLoader.getInstance();
            loader.displayImage(url, image);

        }

当一个小数量的图像，一切顺利，但当它喜欢的100图像ImageLoader让我喜欢10对15图像然后递给我那个例外：

最佳答案 (Best Answer)

Add

 android:largeHeap="true" 

within the application tag into your manifest

Example

 <application
    android:allowBackup="true"
    android:largeHeap="true"
    android:icon="@drawable/ic_launcher" >
