如何获得Android崩溃日志?

I have an app that is not in the market place (signed with a debug certificate), but would like to get crash log data, whenever my application crashes. Where can I find a log of why my app crashed?

我有一个不在市场上的应用程序(用调试证书签名)，但是每当我的应用程序崩溃时，我希望得到崩溃日志数据。我在哪里可以找到我的应用崩溃的原因的日志?

If your app is being downloaded by other people and crashing on remote devices, you may want to look into an Android error reporting library (referenced in this SO post). If it's just on your own local device, you can use LogCat. Even if the device wasn't connected to a host machine when the crash occurred, connecting the device and issuing an adb logcat command will download the entire logcat history (at least to the extent that it is buffered which is usually a loooot of log data, it's just not infinite). Do either of those options answer your question? If not can you attempt to clarify what you're looking for a bit more?

如果你的应用程序被其他人下载并在远程设备上崩溃，你可能需要查看Android错误报告库(在本文SO post中引用)。如果只是在本地设备上，可以使用LogCat。即使设备在崩溃发生时没有连接到主机，连接设备并发出adb logcat命令也会下载整个logcat历史记录(至少在它被缓存的程度上，这通常是大量的日志数据，它不是无限的)。这两个选项是否都能回答你的问题?如果没有，你能试着澄清你想要的更多一点吗?

The way to do this is to implement the Thread.UncaughtExceptionHandler interface and pass it to Thread.setDefaultUncaughtExceptionHandler() at the beginning of your Activity's onCreate(). Here is the implementation class TopExceptionHandler.

这样做的方法是实现线程。UncaughtExceptionHandler接口，并在活动onCreate()的开头将其传递给Thread.setDefaultUncaughtExceptionHandler()。这是实现类TopExceptionHandler。

public class TopExceptionHandler implements Thread.UncaughtExceptionHandler {
    private Thread.UncaughtExceptionHandler defaultUEH;
    private Activity app = null;

    public TopExceptionHandler(Activity app) {
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
        this.app = app;
    }

    public void uncaughtException(Thread t, Throwable e) {
        StackTraceElement[] arr = e.getStackTrace();
        String report = e.toString()+"\n\n";
        report += "--------- Stack trace ---------\n\n";
        for (int i=0; i<arr.length; i++) {
            report += "    "+arr[i].toString()+"\n";
        }
        report += "-------------------------------\n\n";

        // If the exception was thrown in a background thread inside
        // AsyncTask, then the actual exception can be found with getCause

        report += "--------- Cause ---------\n\n";
        Throwable cause = e.getCause();
        if(cause != null) {
            report += cause.toString() + "\n\n";
            arr = cause.getStackTrace();
            for (int i=0; i<arr.length; i++) {
                report += "    "+arr[i].toString()+"\n";
            }
        }
        report += "-------------------------------\n\n";

        try {
            FileOutputStream trace = app.openFileOutput("stack.trace", 
                                                        Context.MODE_PRIVATE);
            trace.write(report.getBytes());
            trace.close();
        } catch(IOException ioe) {
        // ...
        }

        defaultUEH.uncaughtException(t, e);
    }
}

Note We let the Android framework's defaultUEH to handle it.

注意，我们让Android框架的defaultUEH来处理它。

At the top of your Activity register an instance of above class like this:

在你的活动顶部注册一个以上类的实例，如:

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Thread.setDefaultUncaughtExceptionHandler(new TopExceptionHandler(this));
...

This handler saves the trace in a file. When ReaderScope restarts next time, it detects the file and prompts the user if he/she wants to email it to the developer.

此处理程序将跟踪保存在文件中。当ReaderScope下次重新启动时，它会检测到文件并提示用户，如果他/她想要将它发送给开发人员。

To Email the Stack Trace, execute following code to pack it in an email.

要发送堆栈跟踪，请执行以下代码，将其打包到电子邮件中。

try {
    BufferedReader reader = new BufferedReader(
        new InputStreamReader(ReaderScopeActivity.this.openFileInput("stack.trace")));
    while((line = reader.readLine()) != null) {
        trace += line+"\n";
    }
} catch(FileNotFoundException fnfe) {
    // ...
} catch(IOException ioe) {
    // ...
}

Intent sendIntent = new Intent(Intent.ACTION_SEND);
String subject = "Error report";
String body = "Mail this to appdeveloper@gmail.com: " + "\n" + trace + "\n";

sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {"readerscope@altcanvas.com"});
sendIntent.putExtra(Intent.EXTRA_TEXT, body);
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
sendIntent.setType("message/rfc822");

ReaderScopeActivity.this.startActivity(Intent.createChooser(sendIntent, "Title:"));

ReaderScopeActivity.this.deleteFile("stack.trace");

Or you can also use ACRA Error Reporting System.Just Include the ACRA.jar in your project libs and use the below code snippet before your launcher activity class declaration

或者您也可以使用ACRA错误报告系统。只包括肢端。在您的项目libs中，使用以下代码片段，在您的启动活动类声明之前。

@ReportsCrashes(formKey = "", mailTo = "abc@gmail.com;def@yahoo.com", mode = ReportingInteractionMode.SILENT)

You can use Apphance. This is a cross-platform service (now mainly Android, iOS with other platforms on their way) which allows to debug remotely any mobile device (Android, iOS now - others under development). It's much more than just a crashlog, in fact it is much more: logging, reporting of problems by testers, crashlogs. It takes about 5 minutes to integrate. Currently you can request for access to closed beta.

您可以使用Apphance。这是一个跨平台的服务(现在主要是Android, iOS和其他平台)，可以远程调试任何移动设备(Android, iOS现在——其他正在开发的设备)。它不仅仅是一个日志记录，实际上它更多:日志记录、测试人员报告问题、日志记录。积分大约需要5分钟。目前，您可以请求访问封闭的beta。

Disclaimer: I am CTO of Polidea, a company behind Apphance and co-creator of it.

Update: Apphance is no longer closed beta! Update 2: Apphance is available as part of http://applause.com offering

更新:升级不再是封闭的beta!更新2:Apphance是http://applause.com提供的一部分。

If you're using Eclipse, make sure you use debug and not run. Make sure you are in the debug perspective (top right) You may have to hit 'Resume' (F8) a few times for the log to print. The crash log will be in the Logcat window at the bottom- double click for fullscreen and make sure you scroll to the bottom. You'll see red text for errors, the crash trace will be something like

如果您正在使用Eclipse，请确保使用了debug而不是run。确保您处于debug透视图(右上角)中，您可能需要多次点击“Resume”(F8)才能打印日志。崩溃日志将在底部的Logcat窗口-双击全屏，确保你滚动到底部。您将看到错误的红色文本，崩溃跟踪将是类似的
