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");
?>

可以使用Thread.setDefaultUncaughtExceptionHandler()处理这些异常，但是这似乎与Android处理异常的方法相混淆。我尝试使用这样的处理程序:

private class ExceptionHandler implements Thread.UncaughtExceptionHandler {
    @Override
    public void uncaughtException(Thread thread, Throwable ex){
        Log.e(Constants.TAG, "uncaught_exception_handler: uncaught exception in thread " + thread.getName(), ex);

        //hack to rethrow unchecked exceptions
        if(ex instanceof RuntimeException)
            throw (RuntimeException)ex;
        if(ex instanceof Error)
            throw (Error)ex;

        //this should really never happen
        Log.e(Constants.TAG, "uncaught_exception handler: unable to rethrow checked exception");
    }
}

然而，即使重新抛出异常，我也无法获得所需的行为，即记录异常，同时仍然允许Android关闭组件，所以我在一段时间后放弃了它。

你可以试试ACRA (Android应用程序崩溃报告)库:

ACRA是一个库，使Android应用程序自动张贴他们的崩溃报告到GoogleDoc的形式。它是针对android应用程序开发人员，帮助他们从他们的应用程序崩溃或行为错误时获取数据。

它很容易安装在你的应用程序中，高度可配置，不需要你在任何地方托管服务器脚本…报告被发送到谷歌文档电子表格!

虽然本页上的许多答案都很有用，但它们很容易过时。AppBrain网站汇总统计数据，让您找到当前最流行的崩溃报告解决方案:

Android崩溃报告库

你可以看到，在发布这张图片时，5.24%的应用使用了Crashlytics，安装率为12.38%。

您还可以为它使用整个(简单的)服务，而不仅仅是库。我们公司刚刚为此发布了一项服务:http://apphance.com。

It has a simple .jar library (for Android) that you add and integrate in 5 minutes and then the library gathers not only crash information but also logs from running application, as well as it lets your testers report problems straight from device - including the whole context (device rotation, whether it is connected to a wifi or not and more). You can look at the logs using a very nice and useful web panel, where you can track sessions with your application, crashes, logs, statistics and more. The service is in closed beta test phase now, but you can request access and we give it to you very quickly.

声明:我是Polidea的CTO，也是这项服务的共同创建者。

现在Firebase崩溃报告非常流行，也更容易使用。 详情请参考以下连结: Firebase崩溃报告
