上傳文件丟失OutOfMemoryError

我想上傳一個文件到網絡服務器使用的代碼。但是當大小> 6M，拋出一個致命異常java.lang.OutOfMemoryError上傳文件丟失OutOfMemoryError

HttpURLConnection conn; 
    URL url = new URL(mServerUrl); 
    conn = (HttpURLConnection) url.openConnection(); 
    conn.setDoOutput(true); 
    conn.setDoInput(true); 
    conn.setUseCaches(false); 
    conn.setRequestMethod("POST"); 
    conn.setRequestProperty("Content-Type", file.getContentType()); 
    conn.setRequestProperty("Connection", "close"); 
    conn.setRequestProperty("Charset", "UTF-8"); 
    conn.connect(); 
    DataOutputStream os = new DataOutputStream(conn.getOutputStream()); 

    int totalSize = 0; 
    byte[] buffer = new byte[1024]; 
    int len = 0; 
    while ((len = file.getInStream().read(buffer, 0, 1024)) != -1) { 

     totalSize += len; 
     WDLog.i("totalSize = " + totalSize); 
     os.write(buffer, 0, len); 

    } 

    file.getInStream().close(); 
    os.flush(); 
    os.close();

我能做什麼來解決這個問題？感謝

和在

os.write（緩衝液，0，LEN）;

這條線會拋出錯誤。

你可以發佈Logcat消息嗎？哪一行是你得到的例外。 – Karthik 2011-12-26 11:22:33

Hi ray。你能否在這裏添加你的答案並進行詳細說明。我非常震驚。 – 2012-01-20 07:49:55

根據塊的基礎將文件上傳到服務器塊。例。首先從服務器獲取響應後上傳1024字節的數據，然後上傳1024字節的數據，直到文件的所有數據上傳。

我解決這個問題是這樣的：在while循環，如果添加（總計TOTALSIZE> 5 * 1024 * 1024）爆發，做（ \t \t os.flush（）; \t \t os.close（）; conn.disconnect（） ; \t \t System.gc（）;）不要關閉文件inputstream。如果未完成重做上傳功能。 – ray 2011-12-27 02:56:54

你可以舉例/ – 2014-05-21 07:54:00

如果您在仿真器上測試此代碼，請確保您的RAM大小接近實際設備值。

我測試它在HTC G7 – ray 2011-12-26 11:40:01

然後嘗試上傳文件塊的塊，因爲Sunil庫馬爾Sahoo說 – 2011-12-26 11:42:44
