捕获错误和用户信息 [英] Catching error and user information

问题描述

我有一个问题，因为我的应用程序在后台运行，有时会出现一个错误，将其关闭。如何捕捉任何活动或服务的错误，以播放声音和通知栏上添加信息？

I have a problem because my application runs in the background and sometimes an error occurs that closes it. How to catch an error in any activity or service in order to play a sound and add info on the notification bar?

推荐答案

要解决这个问题，你可以使用的UncaughtExceptionHandler接口这一点。

To solve this problem, you can use uncaughtExceptionHandler interface for this.

public class ExceptionHandler implements UncaughtExceptionHandler{

Utils utils ;
Context context;
private final String LINE_SEPARATOR = "\n";

public ExceptionHandler(Context con) {
    // TODO Auto-generated constructor stub
    context = con;
}

@Override
public void uncaughtException(Thread arg0, Throwable arg1) {
    // TODO Auto-generated method stub

    StringWriter stackTrace = new StringWriter();
    arg1.printStackTrace(new PrintWriter(stackTrace));
    StringBuilder errorReport = new StringBuilder();
    errorReport.append("************ CAUSE OF ERROR ************\n\n");
    errorReport.append(stackTrace.toString());

    errorReport.append("\n************ DEVICE INFORMATION ***********\n");
    errorReport.append("Brand: ");
    errorReport.append(Build.BRAND);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Device: ");
    errorReport.append(Build.DEVICE);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Model: ");
    errorReport.append(Build.MODEL);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Id: ");
    errorReport.append(Build.ID);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Product: ");
    errorReport.append(Build.PRODUCT);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("\n************ FIRMWARE ************\n");
    errorReport.append("SDK: ");
    errorReport.append(Build.VERSION.SDK);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Release: ");
    errorReport.append(Build.VERSION.RELEASE);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Incremental: ");
    errorReport.append(Build.VERSION.INCREMENTAL);
    errorReport.append(LINE_SEPARATOR);


    //after this you can do whatever you want , like i start an activity and show error log there


 Intent i = new Intent(context,ExceptionActivity.class);
        i.putExtra("exception",errorReport.toString());
        context.startActivity(i);


        android.os.Process.killProcess(android.os.Process.myPid());
        System.exit(10);





    }
    }

和添加此行

Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));

在每一个活动（其中未捕获的异常可以提高）

in every activity(where uncaught exception can raise)
