Question

我在IntentService中下载文件时遇到致命异常。小文件下载得很好。但9MB + - 文件是问题，即使在高速WIFI连接上它似乎永无止境下载。几分钟后，有一个致命的例外。问题部分是循环（条件线）。

请一些提示？我错过了什么..

例外：

代码：

 private synchronized void download(Intent intent) throws Exception {

    String urlString = intent.getStringExtra("url");
    Log.e("URL DOWNLOAD", urlString);
    String path = intent.getStringExtra("path");
    String name = intent.getStringExtra("name") + ".temp";
    FileOutputStream output;
    URL url = new URL(urlString);
    URLConnection connection = url.openConnection();
    connection.connect();
    InputStream input = new BufferedInputStream(url.openStream());
    File rootFile = new File(path);
    if (!rootFile.exists())
        rootFile.mkdirs();
    File outputFile = new File(rootFile, name);
    if (outputFile.exists()) outputFile.delete();

    output = new FileOutputStream(outputFile);
    byte data[] = new byte[1024];
    int count;


    while ((count = input.read(data)) != -1) {
        output.write(data, 0, count);
    }


    FileControler.renameFile(outputFile, intent.getStringExtra("name"));
    downloadedFile = new File(outputFile.getParent(), intent.getStringExtra("name"));
    output.flush();
    output.close();
    input.close();
}

Answer 1

崩溃可能是由名为Mint的新BugSense库引起的......现在回过头来。

我想告诉您，我们正在处理此问题，并且很快就会修复。现在你可以通过运行Mint.disableNetworkMonitoring（）来禁用网络监控;就在init之前。谢谢你的报告！
