![]() To use logback in the app, you need do a few simple steps. It includes TCP, TCP with TLS, and Google App Engine support, and uses syslog4j for message transmission. The best way is with the logback-syslog4j method. There are two ways to send Android logs to Papertrail. You can set custom alerts right and save searches right from the search bar (no need to click on another menu). It’s easy to use, supports almost every type of log from Android and IOS to devices and servers, and has a familiar search interface. Papertrail was built by engineers for engineers, so it works the way developers do. A cloud-based log management service, like Papertrail, is perfect for this. The number of applications and services generating logs and the high volume of log messages mean you need to turn to an automated solution. You can no longer manage log entries a spreadsheet, or remote in to individual servers for log inspection. Using Papertrail to View and Monitor Android Logging When there’s a service issue, a good log monitoring tool can notify you before your users notice a problem. Monitoring the types of errors and the volume of errors can help you identify bottlenecks and tune your app to improve performance. But what about the back end? To identify back-end issues that could impact the app performance or cause a bad user experience, you need to monitor your apps. ![]() With UX and UI testing, you can usually catch and fix any front-end bugs. So, how can you make your app stand out and be successful? The best way is with high customer ratings, which means providing a top-notch user experience. With the millions of apps already available in the app store, users are presented with many alternatives. ![]() In today’s world, competition among applications is fierce. Let’s walk through what you can do with log monitoring and how to do it with SolarWinds ® Papertrail ™. If a user comes across your app, because of slow speed, they won’t hesitate to uninstall the app. But, for some reason, the app is a bit slow. The app has a nice UI and has all the features a user might demand. Now, what if you’re a developer? You just released an app. Find out which one is fastest, serves your purpose, and has a nice user interface. How do you decide which one to install? Easy! You try out a few of them. When you search for such an app in the Play Store, you’ll find multiple options. Do the stuff after getting the IN_DELETE_SELF event from inotify file descriptor.Let’s imagine you’re looking for a flight ticket booking app for your Android smartphone.Kill the parent process of native monitor process, so that native monitor process became orphan process and adopted by init process.Fork a native process in native method and monitor the data folder with inotify api.Call native method on onStartCommand() method of service.Start an empty service on attachBaseContext() method of Application.I do the following things to get all the work done: How do we make the monitor process running even after the application has been removed? I've made an experiment and found that the native process forked will survive after the uninstallation. Remove file or directory from watch list with inotify_rm_watch().read() from the inotify file descriptor to wait for the event.Add file or directory to watch list of inotify instance with inotify_add_watch().Create an inotify instance with inotify_init().Generally, we have to do the following steps to use the inotify api: So are we gonna do the polled operation to determine the status of data folder? Absolutely not, Linux provided a mechanism called inotify, with the inotify api, we could get notified when operations have been performed on the file or directory. Plan BĪs Android will remove the data folder of application after uninstallation, if the data folder is removed, we could know our application has been removed. So it's not possible? Fortunately, we have Plan B. The code in our listener never gets a chance to execute. The broadcast is sent by AMS after the application removed from device. So we listen to this broadcast and do the work on onReceive() method? Then I wrote a simple POC and proved that it's totally infeasible. I remember that there's a broadcast of action ACTION_PACKAGE_REMOVED when application is uninstalled. Plan AĪt first, I think it's a pretty simple task. Recently I've been working on how to get the same feature on Android. This make developers get feedback from users. If an application is removed in PC, a web page will pop up usually.
