从Android应用程序捕获所有异常并将其发送到服务器或电子邮件[关闭]

Question

我在应用商店中有一个Unity应用，现在有数百个下载。 如何获取用户触发的所有异常？ 基本上，当用户执行触发我捕获的异常的操作时，我想获取电子邮件或能够从某处读取日志。

发送电子邮件或将日志推送到服务器将需要额外的权限，我不知道这是否可行。

亲切的问候

使用WWW可能需要其他权限，但是您需要它。 您可以使用SystemInfo收集相关的系统信息。 还要收集异常信息，并将其存储在WWWForm 。 将带有WWW的WWWForm数据发送到服务器上的php文件。 您可以从php数据中读取数据并将其另存为文本文件。 您也可以将其保存到数据库，然后在html页面中显示。

以下完整的示例代码将收集崩溃日志并将其保存为文件。

C＃ ：

 void Start()
 {
     try
     {
         //Do Something Dangerous
     }
     catch (Exception e)
     {
         //send log if Exception is thrown and caught
         sendLog(e);
     }
 }

 public void sendLog(Exception e)
 {
     string errorLogUrl = "http://yourServerUrl.com/gameName/log.php";
     WWWForm errorForm = new WWWForm();

     //Fill in Important Device Info
     errorForm.AddField("Device OS", SystemInfo.operatingSystem);
     errorForm.AddField("Device Model", SystemInfo.deviceModel);
     errorForm.AddField("Graphics Device Name", SystemInfo.graphicsDeviceName);
     errorForm.AddField("Graphics Device Vendor", SystemInfo.graphicsDeviceVendor);
     errorForm.AddField("Graphics Device Version", SystemInfo.graphicsDeviceVersion);
     errorForm.AddField("Graphics Memory Size", SystemInfo.graphicsMemorySize);
     errorForm.AddField("System Memory Size", SystemInfo.systemMemorySize);

     //Fill in current Scene
     errorForm.AddField("Current Scene", UnityEngine.SceneManagement.SceneManager.GetActiveScene().name);

     //Fill in Important Exception Info
     errorForm.AddField("Exc-StackTrace", e.StackTrace);
     errorForm.AddField("Exc-Source", e.Source);
     errorForm.AddField("Exc-Message", e.Message);

     //FileName
     errorForm.AddField("File Name", DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss" + UnityEngine.Random.Range(1, 900000)));

     WWW www = new WWW(errorLogUrl, errorForm);
     StartCoroutine(WaitForRequest(www));
 }

 private IEnumerator WaitForRequest(WWW www)
 {
     yield return www;

     //Check if we failed to send
     if (www.error != null)
     {
         //Failed To Send.
     }
 }

不是PHP大师。 您可能需要修改以下php代码。

PHP的 ：

<?php

        $DeviceOS = $_POST["Device OS"];
        $DeviceModel = $_POST["Device Model"];
        $GraphicsDeviceName = $_POST["Graphics Device Name"];
        $GraphicsDeviceVendor = $_POST["Graphics Device Vendor"];
        $GraphicsDeviceVersion = $_POST["Graphics Device Version"];
        $GraphicsMemorySize = $_POST["Graphics Memory Size"];
        $SystemMemorySize = $_POST["System Memory Size"];

        $CurrentScene = $_POST["Current Scene"];

        $Exc_StackTrace = $_POST["Exc-StackTrace"];
        $Exc_Source = $_POST["Exc-Source"];     
        $Exc_Message = $_POST["Exc-Message"];       

        $dump_file_name = $_POST["File Name"];

        $finalData = "Device OS: $DeviceOS";
        $finalData = "$finalData\r\nDevice Model: $DeviceModel";
        $finalData = "$finalData\r\nGraphics Device Name: $GraphicsDeviceName";
        $finalData = "$finalData\r\nGraphics Device Vendor: $GraphicsDeviceVendor";
        $finalData = "$finalData\r\nGraphics Device Version: $GraphicsDeviceVersion";
        $finalData = "$finalData\r\nGraphics Memory Size: $GraphicsMemorySize";
        $finalData = "$finalData\r\nSystem Memory Size: $SystemMemorySize";

        $finalData = "$finalData\r\n";

        $finalData = "$finalData\r\nCurrent Scene: $CurrentScene";

        $finalData = "$finalData\r\n";

        $finalData = "$finalData\r\nExc-StackTrace: $Exc_StackTrace";
        $finalData = "$finalData\r\nExc-Source: $Exc_Source";
        $finalData = "$finalData\r\nExc-Message: $Exc_Message";

        $myFile = $dump_file_name . ".txt";
        $fh = fopen($myFile, 'w') or die("can't open file");
        fwrite($fh,$dump_file_name . "," . $finalData . ",");
        fclose($fh);
?>

有现有的免费服务可以做到这一点，只需用谷歌搜索即可。

例如Crashlytics
