Java 上传文件超过300M时应用程序崩溃

我有问题我的应用程序崩溃时，我选择了400米的文件上传，不到300米是上传罚款

我改变了这个

int maxBufferSize =  10 * 10241 * 1024;

到

还是一样的问题

我错过什么了吗

protected String doInBackground(String... urls) {

    String upLoadServerUri = upApi.uploadUrl;
    String fileName = this.file_path;
    HttpURLConnection connection = null;
    DataOutputStream outputStream = null;
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize =  10 * 10241 * 1024;
    File sourceFile = new File(fileName);
    int sentBytes = 0;
    long fileSize = sourceFile.length();

    try
    {
        FileInputStream fileInputStream = new FileInputStream(new File(fileName));

        URL url = new URL(upLoadServerUri);
        connection = (HttpURLConnection) url.openConnection();

        // Allow Inputs & Outputs
        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setUseCaches(false);
        connection.setChunkedStreamingMode(1024);
        // Enable POST method
        connection.setRequestMethod("POST");

        connection.setRequestProperty("Connection", "Keep-Alive");
        connection.setRequestProperty("Content-Type",     "multipart/form-data;boundary="+boundary);

        outputStream = new DataOutputStream(     connection.getOutputStream() );
        outputStream.writeBytes(twoHyphens + boundary + lineEnd);
        outputStream.writeBytes("Content-Disposition: form-data; name=\"file[]\";filename=\""+ fileName + "\"" + lineEnd);
        outputStream.writeBytes(lineEnd);

        buffer = new byte[maxBufferSize];

        while (true)
        {
            int bytesToRead = Math.min(maxBufferSize, fileInputStream.available());

            // Break if complete
            if(bytesToRead == 0){ break; }

            // Read bytes
            bytesRead = fileInputStream.read(buffer, 0, bytesToRead);

            // Write bytes
            outputStream.write(buffer, 0, bytesRead);

            // Update progress dialog
            sentBytes += bytesRead;

            // Publish progress
            double progress = (double)sentBytes / fileSize;
            publishProgress((int)progress);
        }

您试图分配的缓冲区太大（

10*10241*1024=104867840字节

）。甚至

10241*1024

也太大（

10486784字节

）。尝试将其减小到

1024*1024

（

1048576

）或更小；您是否能够在网络连接上以足够快的速度传输数据，从而需要如此大的缓冲区，这是值得怀疑的。
