Question

I am in a strange problem right now.
I’ve been trying to upload an image from my android app to the server, however it works fine when i am using wifi connection but when i am on GPRS the application just keeps on processing for an infinite amount of time. Below is the code:

    try
    {
        Log.i(TAG,"publishFileToServer Called...");
        FileInputStream fileInputStream = new FileInputStream(new File(filePath) );
        URL url = new URL(urlServer);
        System.setProperty("http.keepAlive", "false");
        connection = (HttpURLConnection) url.openConnection();
        Log.i(TAG,"publishFileToServer Called... 1");
        // Allow Inputs & Outputs
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setUseCaches(false);
        Log.i(TAG,"publishFileToServer Called... 2");
        // Enable POST method
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Connection", "Keep-Alive");
        connection.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
        Log.i(TAG,"publishFileToServer Called...3");
        outputStream = new DataOutputStream( connection.getOutputStream() );
        outputStream.writeBytes(twoHyphens + boundary + lineEnd);
        outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + filePath +"\"" + lineEnd);
        outputStream.writeBytes(lineEnd);
        Log.i(TAG,"publishFileToServer Called...4");
        bytesAvailable = fileInputStream.available();
        bufferSize = Math.min(bytesAvailable, maxBufferSize);
        buffer = new byte[bufferSize];
        Log.i(TAG,"publishFileToServer Called...5");
        // Read file
        bytesRead = fileInputStream.read(buffer, 0, bufferSize);
        Log.i(TAG,"publishFileToServer Called...6");
        while (bytesRead > 0)
        {
            outputStream.write(buffer, 0, bufferSize);
            bytesAvailable = fileInputStream.available();
            bufferSize = Math.min(bytesAvailable, maxBufferSize);
            bytesRead = fileInputStream.read(buffer, 0, bufferSize);
        }
        Log.i(TAG,"publishFileToServer Called...7");
        outputStream.writeBytes(lineEnd);
        outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
        Log.i(TAG,"publishFileToServer Called...8");
        // Responses from the server (code and message)
        int serverResponseCode = connection.getResponseCode();
        Log.i(TAG,"publishFileToServer: ServerResponseCode = "+serverResponseCode);
        String serverResponseMessage = connection.getResponseMessage();
        Log.i(TAG,"publishFileToServer: ServerResponseMessage = "+serverResponseMessage);
        Log.i(TAG,"publishFileToServer Called...9");
        fileInputStream.close();
        outputStream.flush();
        outputStream.close();
        Log.i(TAG,"publishFileToServer Called...10");
    }
    catch (Exception ex)
    {
        Log.e(TAG,"publishFileToServer: "+ex.getMessage());
    }

It’s noticeable that i use this same code to upload a text file an it works fine even on GPRS, i’ve tried to narrow it down and my application goes into the problem right before the getResponse() method when I am uploading an image.

Answer 1

Apparently the problem went away after a re-install of the sdk.
