執行的AsyncTask時，其給內存不足的錯誤了

我試圖運行android.its給錯誤跟蹤執行的AsyncTask時，其給內存不足的錯誤了

的現有項目和相關的源代碼到它顯示這個錯誤是

class InitThumbnailDiskCacheTask extends AsyncTask<Void, Void, Void> { 
     @Override 
     protected Void doInBackground(Void... params) { 
      synchronized (thumbnailLruCacheLock) { 
       // Check if media is mounted or storage is built-in, if so, try and use external cache dir 
       // otherwise use internal cache dir 
       final String cachePath = 
         Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()) || 
           !Environment.isExternalStorageRemovable() ? getExternalCacheDir().getPath() : 
             getCacheDir().getPath(); 
           Log.i("Cache Path","Cache Path"+cachePath); 

       try { 
        if (!isCancelled()) { 
         thumbnailLruCache = DiskLruCache.open(
           new File(cachePath + File.separator + "thumbnails"), 
           APP_VERSION, 
           VALUE_COUNT, 
           DISK_CACHE_SIZE); 
        } 
       } catch (IOException e) { 
        Log.e(TAG, "Failed to initialize thumbnail cahce", e); 
       } 
       thumbnailLruCacheStarting = false; // Finished initialization 
       thumbnailLruCacheLock.notifyAll(); // Wake any waiting threads 
      } 
      return null; 
     } 
    }

任何人都可以請指導線如何解決它。

這是你的DiskLruCache.java文件的第226行嗎？ – nKn

https://github.com/JakeWharton/DiskLruCache/blob/master/src/main/java/com/jakewharton/disklrucache/DiskLruCache.java這是圖書館 –

Log.i中的主要問題（「Cache Path」，「緩存路徑「+ cachePath）; LogCat中不顯示此日誌 –

您正在分配太多內存。在Android中，進程的內存有限（請參閱this question），並且進程內存的總數不能超過此數量，否則您將獲得OutOfMemoryError。考慮分幾步拆分你的加載，以便GC可以釋放未使用的內存。
