Android 文件上载期间Asynctask java.lang.OutOfMemoryError异常

在应用程序的文件上载测试期间，我遇到

java.lang.OutOfMemoryError

异常。这是非常奇怪的，只发生在一些三星设备（GT9300）

以下是asynctask

FileUploadTask

的跟踪：

源文件（FileUpload.java）行包括：

1010:               final FileInputStream fileInputStream = new FileInputStream(new File(string));
                    FileUpload.this.uploadTimeStart = System.currentTimeMillis();
                    final HttpURLConnection httpURLConnection = (HttpURLConnection) new URL(uploadURL).openConnection();
                    httpURLConnection.setDoInput(true);
                    httpURLConnection.setDoOutput(true);
                    httpURLConnection.setUseCaches(false);
                    httpURLConnection.setRequestMethod("POST");
                    httpURLConnection.setRequestProperty("Connection", "Keep-Alive");
                    httpURLConnection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + "*****");
                    final File file = new File(FileUpload.this.rootDir + FileUpload.this.folderName, FileUpload.this.fileName);
                    final FileInputStream fileInputStream2 = new FileInputStream(file);
1021                final byte[] array2 = new byte[(int) file.length()];
                    fileInputStream2.read(array2);
                    fileInputStream2.close();
                    fileInputStream.close();

如果需要我方提供任何数据，请告诉我。

我认为您需要尝试其他数据technique@madhukar在清单中启用

android:largeHeap=“true”

一次。一旦检查这个链接，文件有多大？谢谢你的评论。文件大小将从10 MB到50 MB不等，具体取决于连接（4G、WIFI）。这有关系吗？@Sree你能推荐其他的技巧吗？。我正在计算文件上传带宽。
