通用圖像加載程序：OutOfMemory錯誤

我正在使用通用圖像加載程序1.6.2.jar（最新）。我正在嘗試使用此庫下載並緩存該圖像。我有47個圖像從服務器下載，共5.22 Mb.My最大圖像的尺寸是720X480和143KB大小。它順利，直到40-41影像後，它給錯誤通用圖像加載程序：OutOfMemory錯誤

我所看到的和落實有關git的樞紐OOM建議。我跟着他們，我仍然有錯誤。這裏是我的代碼

if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) 
     cacheDir=new File(android.os.Environment.getExternalStorageDirectory(),"neongall"); 
    else 
     cacheDir=context.getCacheDir(); 
    if(!cacheDir.exists()) 
     cacheDir.mkdirs(); 

    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) 
    .threadPoolSize(3) 
    .threadPriority(Thread.NORM_PRIORITY - 1) 
    .memoryCache(new WeakMemoryCache()) 
    .denyCacheImageMultipleSizesInMemory() 
    .offOutOfMemoryHandling() 
    .discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75) 
    .discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation 
    .discCacheFileNameGenerator(new HashCodeFileNameGenerator()) 
    .imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000)) // connectTimeout (5 s), readTimeout (20 s) 
    .defaultDisplayImageOptions(DisplayImageOptions.createSimple()) 
    .enableLogging() 
    .build(); 
    //Initialize ImageLoader with created configuration. Do it once on Application start. 
    imageLoader.init(config); 


    options = new DisplayImageOptions.Builder() 
    .cacheOnDisc() 
    .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2) 
    .displayer(new RoundedBitmapDisplayer(10)) 
    .build();

在此先感謝。

首先你的配置：

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) 
.threadPoolSize(3) // equal to default value 
.threadPriority(Thread.NORM_PRIORITY - 1) // equal to default value 
.memoryCache(new WeakMemoryCache()) 
.denyCacheImageMultipleSizesInMemory() 
.offOutOfMemoryHandling() 
.discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75) 
.discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation 
.discCacheFileNameGenerator(new HashCodeFileNameGenerator()) // equal to default value 
.imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000)) // connectTimeout (5 s), readTimeout (20 s) 
.defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // equal to default value 
.enableLogging() 
.build();

等於

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) 
.memoryCache(new WeakMemoryCache()) 
.denyCacheImageMultipleSizesInMemory() 
.offOutOfMemoryHandling() 
.discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75) 
.discCache(new UnlimitedDiscCache(cacheDir)) 
.imageDownloader(new URLConnectionImageDownloader(120 * 1000, 120 * 1000)) 
.enableLogging() 
.build();

禁止複製配置從README！

你爲什麼要關閉OutOfMemory處理？如果你這樣做，那麼你應該自己在ImageLoadingListener.onLoadingFailed(FailReason.OUT_OF_MEMORY)中處理OOM錯誤。

我對你的建議：在配置

刪除.offOutOfMemoryHandling()選項刪除在顯示選項中配置.discCacheExtraOptions(720, 480, CompressFormat.JPEG, 75)選項
使用.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
你真的需要RoundedBitmapDisplayer？請參閱文檔，它在舍入期間在內存中創建額外的位圖。如果可以，請避免使用它。
