![]() Android Studio Emulator Not Working Camera How To Set It![]() Enable USB Debugging on DeviceTo enable communication between ADB and a physical Android device, we’ll need to turn Developer options on and enable USB debugging. You can use an emulator as an alternative if you don’t have an Android phone. I’ll use Android Studio and run the example app on a physical Android phone. Getting the Crash LogFirst, let’s walk through the four steps you need to follow to get the crash log after the app crashes. Changing log level to Error will help trim things down so it’s easier to find the critical issue that caused the app to crash. Went back to the main settings UI, selected Additional settings, and looked for Developer options —in Developer options, you can turn on USB debuggingWith our device connected via USB before the crash, Android Studio’s Logcat feature will display information about our app and the crash.To switch to Logcat view on Android Studio, click on the Logcat label in the bottom tool window.Below is the report from Logcat just after the crash occurred:The Logcat window allows you to search and filter logs. Tapped on Build number (MIUI version on my device) multiple times until I got a message reading “You are now a developer” Opened settings and went to About phone To enable USB debugging on my Redmi device, which is running a recent build of the MIUI, I did the following: In Android, before apps can use some OS features and services like the camera, phone calls, internet, and read/write storage, the app needs to request permission and the user must grant access.Our example app requires permission to make phone calls ( android.permission.CALL_PHONE), but the app currently doesn’t validate the permission has been granted. If you’re interested in some best practices on creating event messages, check out the article on JSON logging.Logcat shows our app crashed due to a security exception. Creating event messages like this is key to being able to quickly identify what’s happening. Fixing the CrashFortunately, the log entry included enough information, so we were able to pinpoint which part of our code was in execution just before the crash. From this, we know generally what happened and where we need to focus to start working on a fix. You might also want to make sure you’re reading logs for the correct device and app.The following info from the log trace gives some idea about why our app crashed: java.lang.SecurityException: Permission Denial: starting Intent Looking at the trace, you can see where the error occurred in our app, including the class and the line of code. Logcat also reports the class, method, and line of code associated with the crash. We then used the information from Logcat to isolate the issue with our app. Burning Is OptionalBy running the app on a device connected to Android Studio via ADB, we were able to view crash logs on Logcat. This can be done with an if statement or however else you prefer.START FREE TRIAL Crashing Is Inevitable. Not explicitly verifying the user has granted the required permission may lead to crashes on some devices and Android versions (Android 6.0 in our test).To fix this issue, the app needs to verify users on the affected OS version have granted the necessary permissions before running the code to start a phone call. ![]() To avoid uninstalls or—worse—bad ratings, it’s important to catch and diagnose app crashes fast so you can work on getting a fix out to users quickly. Unfortunately, you can only test on a limited number of devices, and users are likely to interact with your apps in ways you can’t predict.This means you need to actively monitor event logs to catch issues early. The best way to avoid issues is to catch them before your app goes live. or include integrations with external services or other applications.In these cases, simply collecting and view the logs is challenging.As a developer—especially an app developer—you know you can’t afford to release a buggy app. include user-specific logic to generate behavior for different users based on their account and user-generated content Winx screen recorder for mac reviewHe writes code in Java, Kotlin, and PHP.

For crash logs, the tail feature in Papertrail is one I use frequently.
