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。

感谢资源在Stackoverflow中帮助我找到这个答案。

你可以直接在电子邮件中找到远程Android崩溃报告。记住你必须把你的电子邮件放在CustomExceptionHandler类中。

public static String sendErrorLogsTo = "tushar.pandey@virtualxcellence.com" ;

步骤:

1)在onCreate你的活动使用这段代码。

    if(!(Thread.getDefaultUncaughtExceptionHandler() instanceof CustomExceptionHandler)) {
        Thread.setDefaultUncaughtExceptionHandler(new CustomExceptionHandler(this));
    }   

第二)使用(rrainn)的CustomExceptionHandler类的重写版本,根据我的phpscript。

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) {

        } catch (IOException e) {
            e.printStackTrace();
        }

有个机器人图书馆叫夏洛克。它为您提供完整的崩溃报告以及设备和应用程序信息。 无论何时发生崩溃,它都会在通知栏中显示一个通知,并且在单击该通知时,它会打开崩溃详细信息。您还可以通过电子邮件或其他共享选项与他人分享崩溃详情。

安装

android {
    dataBinding {
      enabled = true
    }
}

compile('com.github.ajitsing:sherlock:1.0.0@aar') {
    transitive = true
}

Demo

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!

刚开始使用ACRA https://github.com/ACRA/acra使用谷歌形式作为后端,它非常容易设置和使用,这是默认的。

但是发送报告到谷歌表单将被弃用(然后删除): https://plus.google.com/118444843928759726538/posts/GTTgsrEQdN6 https://github.com/ACRA/acra/wiki/Notice-on-Google-Form-Spreadsheet-usage

无论如何,可以定义自己的发件人 https://github.com/ACRA/acra/wiki/AdvancedUsage#wiki-Implementing_your_own_sender 例如,你可以试着给发件人发电子邮件。

用最少的努力就可以将报告发送到bugsense: http://www.bugsense.com/docs/android#acra

注意:无bug感知账号每月最多500个报告

我还找到了一个更好的web应用程序来跟踪错误报告。

https://mint.splunk.com/

配置步骤少。

使用上面的链接登录或注册并配置。一旦你创建了一个应用程序,他们将提供如下所示的一行来配置。

Mint initAndStartSession (YourActivity。这“api_key”);

在应用程序的build.gradl中添加以下内容。

android { ... 存储库{ Maven {url "https://mint.splunk.com/gradle/"} } ... } 依赖关系{ ... 编译”com.splunk.mint:薄荷:4.4.0” ... }

添加上面复制的代码,并将其添加到每个活动中。 Mint.initAndStartSession (YourActivity。这个,”api_key”);

就是这样。你登录并进入应用程序仪表板,你会得到所有的错误报告。

希望它能帮助到别人。
