Android Can'；无法修复异步任务崩溃：挂起或SSL连接或其他原因？,android,eclipse,ssl,android-asynctask,android-pendingintent,Android,Eclipse,Ssl,Android Asynctask,Android Pendingintent,几年前我开发了一款Android应用程序。它仍然在Play Store上，我用Eclipse和旧的Android开发工具（我从未使用过Android Studio）不断更新它，修复一些小错误 第一次启动时，我的应用程序开始从服务器下载数据并将其保存在内部数据库中（我使用了一个AyncTask，下面是源代码：）。在大多数手机上一切都很顺利 但在某些手机上，下载失败，用户无法使用该应用程序。 我买了一部这样的手机，把它连接到LogCat上，看看会发生什么。以下是日志： 04-04 21:07:50.

我认为问题可能在于这些信息：

04-04 21:29:11.295: E/NetworkScheduler.SR(1879): Invalid parameter app
04-04 21:29:11.296: E/NetworkScheduler.SR(1879): Invalid package name : Perhaps you didn't include a PendingIntent in the extras?
…或者可能与SSL连接有关：

04-04 21:13:50.296: V/NativeCrypto(1879): Read error: ssl=0xb84d38c0: I/O error during system call, Connection reset by peer
04-04 21:13:50.315: V/NativeCrypto(1879): SSL shutdown failed: ssl=0xb84d38c0: I/O error during system call, Broken pipe
我想不出有什么问题。我尝试了几种设备，结果如下：

它适用于以下手机：

  • 华为：6.0
  • 三星A5:6.0.1
  • 一加二：6.0.1
  • 华硕Zenphone:6.1
  • 一加：37.0
  • 宏达一号：7.0
它在以下手机上不工作（在AsynTask执行期间崩溃）：

  • 三星S3 Neo 4.4.2
  • 华硕5.0.2
  • 三星S2 5.1.1
  • 三星Neo 5.1.1
对于故障排除，另一件可能值得注意的事情是，大约2个月前，我在我的主机上启用了SSL证书，应用程序从该主机获取数据

我已经搜索过关于这个问题的类似问题，但没有一个对我有帮助。
因为在大多数手机上，这个应用程序都可以正常工作，所以我不明白为什么在旧版本的Android上，它会因为这个LogCat而崩溃。有什么想法吗？

AsynTask错误的原因是在SSL连接中使用了
DefaultHttpClient
。Android已经弃用了Apache模块，该模块包括DefaultHttpClient，因为API级别为22。 我解决了在
doInBackground
方法中替换一些代码的问题

之前：

@Override
protected String doInBackground(String... urls) {
    int timeout = 10;
    int i, count = 0;

    BasicHttpParams basicParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(basicParams, timeout * 1000);
    HttpConnectionParams.setSoTimeout(basicParams, timeout * 1000 );
    DefaultHttpClient client = new DefaultHttpClient(basicParams);

    StringBuilder stringBuilder = new StringBuilder();
    for (i = 0; i < urls.length; i++) {
        HttpGet request = new HttpGet(urls[i]);
        request.addHeader("Cache-Control", "no-cache");

        try {
            HttpResponse response = client.execute(request);
            HttpEntity entity = response.getEntity();
            InputStreamReader in = new InputStreamReader(entity.getContent());
            BufferedReader reader = new BufferedReader(in);
            String line = "";

            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);

                count++;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        publishProgress(count * 100 / urls.length);
    }

    return stringBuilder.toString();
}

@覆盖

多亏了这个

上面的代码是关于GET请求的。由于这一点，我还解决了POST请求时AsyncTask的问题。

AsynTask错误的原因是使用SSL连接的
DefaultHttpClient
。Android已经弃用了Apache模块，该模块包括DefaultHttpClient，因为API级别为22。 我解决了在
doInBackground
方法中替换一些代码的问题

之前：

@Override
protected String doInBackground(String... urls) {
    int timeout = 10;
    int i, count = 0;

    BasicHttpParams basicParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(basicParams, timeout * 1000);
    HttpConnectionParams.setSoTimeout(basicParams, timeout * 1000 );
    DefaultHttpClient client = new DefaultHttpClient(basicParams);

    StringBuilder stringBuilder = new StringBuilder();
    for (i = 0; i < urls.length; i++) {
        HttpGet request = new HttpGet(urls[i]);
        request.addHeader("Cache-Control", "no-cache");

        try {
            HttpResponse response = client.execute(request);
            HttpEntity entity = response.getEntity();
            InputStreamReader in = new InputStreamReader(entity.getContent());
            BufferedReader reader = new BufferedReader(in);
            String line = "";

            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);

                count++;
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        publishProgress(count * 100 / urls.length);
    }

    return stringBuilder.toString();
}
