Clear Your Cached Data
Cached data helps apps remember your previous activity for convenience and speed. But sometimes, the cache saves data that makes an app keep crashing. And too much app data can make your entire phone crash. Clear your app cache regularly to keep your phone running smoothly. This will not reset all app data, only non-essential data that helps the app function faster.
Use an optimization tool like Avast Cleanup to easily clear your cached data. It cleans your visible cache, like temporary app files, and lets you quickly clear empty folders and duplicate images that unnecessarily take up space all for free.
Note: Setting options may differ depending on your device and Android version.

Understand The Performance From The Users Perspective
It is easy to cheat during performance testing. The measured speed and the perceived performance from the userâs perspective are not necessarily the same.
Performance metrics tend to focus on the server performance but donât include the user experience. Additionally, for performance tests, other tests like beta versions and user feedback should be reviewed.
Set Up Realistic Benchmarks
One strategy which could be followed is to stress test the app with thousands or millions of users and data.
This gives an overview of how much the app can handle at maximum, but doesnât give a picture of the performance in real-world scenarios where traffic arrives from different devices and operating systems at different times.
Itâs more realistic to play around with number of devices, systems, and numbers of users. Set up testing environments with the apparently random splitting of devices.
At the same time, the simulation shouldnât start from zero. The app normally doesnât start with no server utilization, there will always be users who already have the app and use the server capacity. A realistic test should represent this.

Performance Testing Is A Collection Of Repeated Smaller Tests
A single crash report wonât tell the developers everything they need to know. To gather expressive and useful data, a combination of smaller tests is needed.
Moreover, it is not useful to test the whole system at once and at the end of the development cycle. An app consists of several parts such as the server, database, service, and the device it is used on.
Test the different parts separately as well as together. But: Testing each part individually doesnât equal to testing the whole system!
Combine Qualitative And Quantitative Analytics
Simply being fast isnât enough for sophisticated users.
An app has to be error-free, bug-free, and user-friendly as well. The combination of quantitative analytics like performance testing and qualitative analytics will increase the appâs success.

How Do I Export A Crash Log
Exporting a crash log from Android is useful for developers. Crash reports contain diagnostic information about your application and help you detect bugs. You can record crash logs from your Android application by tapping the build number seven times, then selecting Take bug report. During a crash, the application is stopped and the log is recorded interactively. You can also select a cluster to gather more detailed information about the crash.
Most crash logs are written in the JVM format. In most cases, a crash log is a stack trace of all running threads on a device when an application crashes. It also includes a file/line number and error message. You must be rooted to export crash logs. This is because the Android framework doesnt support logging of errors in native code. If you need to export crash logs for other purposes, you can use a debugging tool like Bugsnag.
This command is important for obtaining crash logs. Getting crash logs from Android requires a few steps. First, you have to connect your phone or emulator to your PC. You must also enable developer options. Then, you can use Device File Explorer to open the files from your device. Once you have the file, launch the app. Youll see a new text in the terminal with the stack trace.
Different Ways To Install And Capture Crash/error Log In Android Devices
Abstract:This article will be helpful for Mobile Apps tester and developer to install and capture logs in Android App. I have tried to explain, how a tester/developer can install Android App and capture Crash/Error log for app crash. Log is helpful for the developer to debug and fixing the bugs.
Introduction:During testing/using of an Android app, App gets crashed or stopped working due to some unexpected causes. When an app crashes, apps process gets terminate and displays a dialog with message i.e.: Unfortunately App has stopped. A Log capture tool captures all process and creates a history known as Log which is required for the developer to debug the code and find out the actual cause of crash/error. Many Android App Development Company relies upon using an integrated development environment for all Android applications and Android Studio always top the list of preferred tools for developers.

Make Sure You Have Stable Wifi
Some apps deal with weak or unstable WiFi connections poorly, and can freeze or crash if the internet is unavailable in the middle of a task when the app expects to have internet access. To troubleshoot this possibility, turn off your WiFi and rely entirely on your cellular signal .
1. Pull down the Control Panel from the top of the screen.
2. Tap the WiFi icon to disable WiFi.
3. Start the app and see if it runs without crashing.
How To Find Logcat Messages
There are two ways to get a logcat message. The usual way will be toinstall an app on your device which knows how to access the logcatinformation. Another way is to install the Android SDK on your computer andget the logcat messages over USB or WiFi.
Using an app on your device
For those who donât want to install software on their computers in order toget the logcat messages, you can download an app such as:
The general idea is to open the app, ask it to start recording logcatmessages, and then try and cause F-Droid to crash. Once it crashes, thelogcat app will save the error messages. These messages can then be copiedand pasted in the F-Droid issuetracker.
On Debian-ish things, try apt-get install pidcat, it has colorization andtab completion even!
Using the Android SDK
Once you have the SDK installed, and are able to use the adb tool, then runthe following command:
Depending on how many apps you have installed/running, it might be a littlebit noisy. If you donât want to post all of that noise online , then you can filter toonly error messages with:
adb logcat *:E

Test Under Different Network Conditions
In the real world, the network conditions of users are constantly changing. They change from one network to another, from low covered regions to completely covered ones to WiFi.
There are hand-overs between different networks. Unforeseen problems can occur quickly and should be avoided as much as possible.
Mobile application performance tests and android crash reporting should run under different and changing network conditions.
How To Fix Apps That Keep Crashing And Freezing
It is very annoying when you are using your favorite app and it suddenly stops and you are directed back to the home screen. This usually occurs when your Wi-Fi or cellular data is slow or unstable, and apps tend to malfunction. Another reason for Android apps crashing problem is the lack of storage space in your device. This occurs when you overload your device’s internal memory with heavy apps as well.
Before you try out the below recommendations as to your solutions, be sure to check if your device’s software and related apps are updated with the latest version. Please check how to update your mobile device’s software in the following order.
Step 1. Go to Settings> Software update.
Step 2. Tap on .
Step 3. Follow the on-screen instructions.

Where Are Crash Logs Stored In Android
Crash logs are important for debugging and troubleshooting Android apps. They are written inside the root of the android OS and cannot be accessed without root permission. A crash-logging solution, such as Perfecto, uses real devices to access the logs. However, many developers use third-party crash log detection services, such as Crashlytics, in order to access their logs. Other developers use application logging within their apps.
To access your logs, go to /data/data/com. android. shell/files/bugreports. If you dont have much space, you can force an app to quit. If you have enough free storage on your device, you may be able to download your crash logs. Alternatively, you can send the logs to a computer. If your computer doesnt have this facility, you can use an emulator.
The diagnostics screen in the Android app lets you view the crash logs for your app. You can filter by clusters to view specific crashes. By selecting a cluster, you can see more details about that specific crash or ANR error. Then, if an issue was discovered during the pre-launch report, it will appear separately. There is detailed crash information in this section, along with logcat from the device and video of the crash. You can save the logs for up to two months. If you are using Android, you should consider opting in to share the data automatically with the Android developer community.
Add Attachments To A Crash Report
You can add binary and text attachments to a crash report. The SDK will send them along with the crash so that you can see them in App Center portal. The following callback will be invoked right before sending the stored crash from previous application launches. It won’t be invoked when the crash happens. Be sure the attachment file is not named minidump.dmp as that name is reserved for minidump files. Here is an example of how to attach text and an image to a crash:
Crashes.GetErrorAttachments = => }
The size limit is currently 7 MB. Attempting to send a larger attachment will trigger an error.

Perform A Factory Reset
The most reliable way to fix crashing apps permanently is a full factory reset. This will return your Android phone to its factory settings. But its irreversible, so back up your phone before performing these steps.
Heres how to perform a factory reset on your Android device:
Open Settings and select General management.
Note: Settings options may differ depending on your device and Android version.
Create Logs With The Android Debug Bridge
By utilizing the Android Debug Bridge, you are able to create log files that cover a certain time frame. Those files are smaller and focus on a particular issue that should ideally be easily reproducible. These logs do not require you to manually look for crash events and are the preferred method to create meaningful logs for reproducible issues.

Finding Your Crash Logs
Here is a customer facing process, to get your app crash logs.
When working with your application, there will be times when a build is unstable. During automation and/or manual testing, you may find that the application just crashes. In Android you will usually see a pop-up on the Home screen “this application has stopped responding”.In iOS, when an app crashes, it is silent and you are returned to home screen.
If you encounter this scenario, don’t panic! You may have discovered an application bug, which is the whole point of testing with Perfecto. Most of these bugs can be fixed by your app developers by providing them with the application crash logs, from the mobile device itself.
It is possible to retrieve the crash log from the Digital Zoom Report. DigitalZoom will identify the failure reason for this type of test as Application crashed, and will add the crash log as an artifact to the test report. For more information go to: Single test report #appCrashApplicationCrashReport
This feature is supported on all iOS versions, Samsung devices running Android 7.0 and above and other Android devices running Android 6.0 and above.
Did The App Crash In The Previous Session
At any time after starting the SDK, you can check if the app crashed in the previous launch:
bool didAppCrash = await Crashes.HasCrashedInLastSessionAsync
This comes in handy in case you want to adjust the behavior or UI of your app after a crash has occurred. Some developers choose to show additional UI to apologize to their users, or want a way to get in touch after a crash has occurred.
This method must only be used after Crashes has been started, it will always return false before start.
