ImageLoader- java.lang.OutOfMemoryError

提案:Androidの公式の提案は、プログラマーとしての私たちがメモリの使用を減らすために努力し、メモリを増大させるのではなく、回収と多重化の方法を考えなければならないということです.メモリが大きいと、gcのたびに時間が長くなり、パフォーマンスが低下しますよ.
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:

Androidアプリケーションを開発し、run_でサーバからtimeはいくつかの画像を展示しているので、私はそのサムネイルを手に入れてAndroidの汎用imageloaderを使ってこれらの画像を得るために:

 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); }

小さな数の画像があれば、すべては順調ですが、好きな100画像ImageLoaderが私に10対15の画像が好きになって、その例外を渡してくれました.

Add

 android:largeHeap="true" 

within the application tag into your manifest
Example

 <application android:allowBackup="true" android:largeHeap="true" android:icon="@drawable/ic_launcher" >    :http://www.4byte.cn/question/183043/imageloader-java-lang-outofmemoryerror.html
