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
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。

虽然本页上的许多答案都很有用,但它们很容易过时。AppBrain网站汇总统计数据,让您找到当前最流行的崩溃报告解决方案:
Android崩溃报告库
你可以看到,在发布这张图片时,5.24%的应用使用了Crashlytics,安装率为12.38%。
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, connected 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?
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) {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("filename", filename));
nvps.add(new BasicNameValuePair("stacktrace", stacktrace));
try {
httpPost.setEntity(
new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
httpClient.execute(httpPost);
} catch (IOException e) {
e.printStackTrace();
}
}
}
upload.php
<?php
$filename = isset($_POST['filename']) ? $_POST['filename'] : "";
$message = isset($_POST['stacktrace']) ? $_POST['stacktrace'] : "";
if (!ereg('^[-a-zA-Z0-9_. ]+$', $filename) || $message == ""){
die("This script is used to log debug data. Please send the "
. "logging message and a filename as POST variables.");
}
file_put_contents($filename, $message . "\n", FILE_APPEND);
?>
index . php
<?php
$myDirectory = opendir(".");
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}
closedir($myDirectory);
$indexCount = count($dirArray);
sort($dirArray);
print("<TABLE border=1 cellpadding=5 cellspacing=0 \n");
print("<TR><TH>Filename</TH><TH>Filetype</th><th>Filesize</TH></TR>\n");
for($index=0; $index < $indexCount; $index++) {
if ((substr("$dirArray[$index]", 0, 1) != ".")
&& (strrpos("$dirArray[$index]", ".stacktrace") != false)){
print("<TR><TD>");
print("<a href=\"$dirArray[$index]\">$dirArray[$index]</a>");
print("</TD><TD>");
print(filetype($dirArray[$index]));
print("</TD><TD>");
print(filesize($dirArray[$index]));
print("</TD></TR>\n");
}

Flurry analytics为你提供崩溃信息、硬件型号、android版本和实时应用使用统计数据。在新的SDK中,他们似乎提供了更详细的崩溃信息http://www.flurry.com/flurry-crash-analytics.html。
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
