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。


当前回答

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。

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。

package com.vxmobilecomm.activity;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class CustomExceptionHandler implements UncaughtExceptionHandler {

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

    Activity activity;

    public CustomExceptionHandler(Activity activity) {
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
        this.activity = activity;
    }

    public void uncaughtException(Thread t, Throwable e) {

        final Writer result = new StringWriter();
        final PrintWriter printWriter = new PrintWriter(result);
        e.printStackTrace(printWriter);
        String stacktrace = result.toString();
        printWriter.close();
        String filename = "error" + System.nanoTime() + ".stacktrace";

        Log.e("Hi", "url != null");
        sendToServer(stacktrace, filename);

        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";
        }

        Throwable cause = e.getCause();

            arr = cause.getStackTrace();
            for (int i = 0; i < arr.length; i++) {
                report += "    " + arr[i].toString() + "\n";
            }
        }
        report += "-------------------------------\n\n";

        defaultUEH.uncaughtException(t, e);
    }

    private void sendToServer(String stacktrace, String filename) {
        AsyncTaskClass async = new AsyncTaskClass(stacktrace, filename,
                getAppLable(activity));
        async.execute("");

        }
        return (String) (lApplicationInfo != null ? lPackageManager
                .getApplicationLabel(lApplicationInfo) : "Unknown");
    }

    public class AsyncTaskClass extends AsyncTask<String, String, InputStream> {
        InputStream is = null;
        String stacktrace;
        final String filename;
        String applicationName;

        AsyncTaskClass(final String stacktrace, final String filename,
                String applicationName) {
            this.applicationName = applicationName;
            this.stacktrace = stacktrace;

        }

        @Override

            HttpClient httpclient = new DefaultHttpClient();

                    "http://suo-yang.com/books/sendErrorLog/sendErrorLogs.php?");

            Log.i("Error", stacktrace);

            try {
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
                        6);

                nameValuePairs.add(new BasicNameValuePair("data", stacktrace));

                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                HttpResponse response = httpclient.execute(httppost);

                HttpEntity entity1 = response.getEntity();

                BufferedHttpEntity bufHttpEntity = new BufferedHttpEntity(
                        entity1);

                is = bufHttpEntity.getContent();

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

            return is;
        }

        @Override
        protected void onPostExecute(InputStream result) {
            super.onPostExecute(result);

            Log.e("Stream Data", getStringFromInputStream(is));

    // convert InputStream to String

        return sb.toString();

    }

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!

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。

你可以直接在Android Studio中做到这一点。只要连接你的手机,运行应用程序,让它崩溃,你就可以直接在Android Studio中查看堆栈跟踪。

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。
