如何从我的Android应用程序中获得崩溃数据(至少堆栈跟踪)?至少在我自己的设备上工作时可以通过电缆检索,但理想的情况是,从我的应用程序在野外运行的任何实例中都可以,这样我就可以改进它,使它更可靠。

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!

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:)

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。

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");
?>
