如果你想立即得到答案，你可以使用logcat

$adb shell logcat -f /sdcard/logoutput.txt *:E

如果您的日志中现在有太多垃圾，请先尝试清除它们。

$adb shell logcat -c

然后尝试运行您的应用程序，然后再次logcat。

For sample applications and debugging purposes, I use a simple solution that allows me to write the stacktrace to the sd card of the device and/or upload it to a server. This solution has been inspired by Project android-remote-stacktrace (specifically, the save-to-device and upload-to-server parts) and I think it solves the problem mentioned by Soonil. It's not optimal, but it works and you can improve it if you want to use it in a production application. If you decide to upload the stacktraces to the server, you can use a php script (index.php) to view them. If you're interested, you can find all the sources below - one java class for your application and two optional php scrips for the server hosting the uploaded stacktraces.

在上下文中(例如主活动)，调用

if(!(Thread.getDefaultUncaughtExceptionHandler() instanceof CustomExceptionHandler)) {
    Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler(
            "/sdcard/<desired_local_path>", "http://<desired_url>/upload.php"));
}

CustomExceptionHandler

public class CustomExceptionHandler implements UncaughtExceptionHandler {

    private UncaughtExceptionHandler defaultUEH;

    private String localPath;

    private String url;

    /* 
     * if any of the parameters is null, the respective functionality 
     * will not be used 
     */
    public CustomExceptionHandler(String localPath, String url) {
        this.localPath = localPath;
        this.url = url;
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }

    public void uncaughtException(Thread t, Throwable e) {
        String timestamp = TimestampFormatter.getInstance().getTimestamp();
        final Writer result = new StringWriter();
        final PrintWriter printWriter = new PrintWriter(result);
        e.printStackTrace(printWriter);
        String stacktrace = result.toString();
        printWriter.close();
        String filename = timestamp + ".stacktrace";

        if (localPath != null) {
            writeToFile(stacktrace, filename);
        }
        if (url != null) {
            sendToServer(stacktrace, filename);
        }

        defaultUEH.uncaughtException(t, e);
    }

    private void writeToFile(String stacktrace, String filename) {
        try {
            BufferedWriter bos = new BufferedWriter(new FileWriter(
                    localPath + "/" + filename));
            bos.write(stacktrace);
            bos.flush();
            bos.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void sendToServer(String stacktrace, String filename) {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("filename", filename));
        nvps.add(new BasicNameValuePair("stacktrace", stacktrace));
        try {
            httpPost.setEntity(
                    new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
            httpClient.execute(httpPost);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

upload.php

<?php
    $filename = isset($_POST['filename']) ? $_POST['filename'] : "";
    $message = isset($_POST['stacktrace']) ? $_POST['stacktrace'] : "";
    if (!ereg('^[-a-zA-Z0-9_. ]+$', $filename) || $message == ""){
        die("This script is used to log debug data. Please send the "
                . "logging message and a filename as POST variables.");
    }
    file_put_contents($filename, $message . "\n", FILE_APPEND);
?>

index . php

<?php
    $myDirectory = opendir(".");
    while($entryName = readdir($myDirectory)) {
        $dirArray[] = $entryName;
    }
    closedir($myDirectory);
    $indexCount = count($dirArray);
    sort($dirArray);
    print("<TABLE border=1 cellpadding=5 cellspacing=0 \n");
    print("<TR><TH>Filename</TH><TH>Filetype</th><th>Filesize</TH></TR>\n");
    for($index=0; $index < $indexCount; $index++) {
        if ((substr("$dirArray[$index]", 0, 1) != ".") 
                && (strrpos("$dirArray[$index]", ".stacktrace") != false)){ 
            print("<TR><TD>");
            print("<a href=\"$dirArray[$index]\">$dirArray[$index]</a>");
            print("</TD><TD>");
            print(filetype($dirArray[$index]));
            print("</TD><TD>");
            print(filesize($dirArray[$index]));
            print("</TD></TR>\n");
        }
    }
    print("</TABLE>\n");
?>

好吧，我看了rrainn和Soonil提供的样本，我找到了一个解决方案 这不会破坏错误处理。

我修改了CustomExceptionHandler，以便它从我们关联的新线程中存储原始的UncaughtExceptionHandler。在新的“uncaughtException”的末尾- 方法，我只是使用存储的UncaughtExceptionHandler调用旧函数。

在DefaultExceptionHandler类中，你需要这样的东西:

public class DefaultExceptionHandler implements UncaughtExceptionHandler{
  private UncaughtExceptionHandler mDefaultExceptionHandler;

  //constructor
  public DefaultExceptionHandler(UncaughtExceptionHandler pDefaultExceptionHandler)
  {
       mDefaultExceptionHandler= pDefaultExceptionHandler;
  }
  public void uncaughtException(Thread t, Throwable e) {       
        //do some action like writing to file or upload somewhere         

        //call original handler  
        mStandardEH.uncaughtException(t, e);        

        // cleanup, don't know if really required
        t.getThreadGroup().destroy();
  }
}

迟来的我支持并相信ACRA是最好的选择。它易于设置和配置。我已经创建了一个详细的指南，使用ACRA获取坠机报告，并使用MandrillAp将其发送到我的电子邮件地址。

对于另一个崩溃报告/异常跟踪服务检查Raygun。io -它有一堆很好的逻辑处理Android崩溃，包括体面的用户体验时，将其插入到你的应用程序(两行代码在你的主活动和几行XML粘贴到AndroidManifest)。

当你的应用程序崩溃时，它会自动抓取堆栈跟踪，硬件/软件的环境数据，用户跟踪信息，任何你指定的自定义数据等。它异步地将其提交给API，这样就不会阻塞UI线程，如果没有可用的网络，它会将其缓存到磁盘。

免责声明:我构建了Android提供商:)

谷歌改变了你实际得到的崩溃报告的数量。以前你只能得到手动报告的错误报告。

自从上次开发者大会和Android Vitals的引入，你也会从用户那里得到崩溃报告，这些用户已经启用了共享诊断数据。

您将看到从用户选择自动共享使用情况和诊断数据的Android设备收集的所有崩溃。可获得前两个月的数据。
