Visual Studio now supports “FIPS compliance mode” Starting with version 16.4, Visual Studio 2019 now supports “FIPS 140-2 compliance mode” when developing apps and solutions for Windows, Azure, and.NET. When you’re developing apps or solutions for non-Microsoft platforms like Linux, iOS, or Android, these platforms may not use FIPS. I have explained Step by step process to install android studio on a mac m1 in 2021. Also, Install Android Emulator on MacBook air m1.Please like this video.
Emulator is a hardware or a software program that allow users to duplicate the functions one system into another. Simply the first system acts as a host and the other one is called as guest.
As for example, users can access the apps installed on their Android phones to a computer or laptop via emulator. The emulator can be of several types that includes software, hardware or CPU.
But sometimes, while accessing the apps on PC via emulator, users come across few errors and common one says “App keeps crashing” on Android emulator. Now this is really a shit situation as users want to experience any video or games better on their system.
Did you also encounter the same error message on your Android emulator and looking how to fix it? if you are facing the same error then just go through this blog completely. Here I am going to show you some best ways to solve “Android emulator app keeps crashing”.
What is the use of emulator in Android?
Well, there are several reasons for emulating Android phone to PC. Android Emulators are used that is an Android Virtual Device and is used to run and test Android application on PC. This platform is basically used by users to play games on a large screen.
Though there is no doubt that users love to play games on their Android devices but if they get a bigger screen size to play then it’s a better experience. Even emulator is also used to run app from Google Play Store.

What Are The Ways To Fix Apps Keeps Crashing On Android Emulator?
Now here are few things that will help you to know what are the reasons for such error and also the solutions to fix “Android emulator app keeps stopping”?
Solution 1: Check for enough disk space
Whenever you come across app keeps crashing on Android emulator, just check whether there is enough space or not. Because when you use emulator then first thing is it checks for free disk space and will not run unless 2GB storage is free.
So when you see that apps keep stopping or crashing then first thing is to check whether there is sufficient disk space or not.
Solution 2: Unsupported Version Of Mac OS
If the Android emulator you are using is on older and unsupported Mac OS X version (10.9) then remember that you have to use older version of HAXM (6.1.2) also. If this is not used then its sure to come across apps keeps crashing issue.
Solution 3: Antivirus Software
Android emulator does not work or stuck on freezing when antivirus software or any other security software’s are installed. Such kind of tools reduces the performance of the emulators and you can come across app keeps stopping error.
There are some antivirus programs that are not compatible with Android emulator. Now it totally depends on the antivirus application installed as the impact differs from software to software.
You should once check the antivirus program by running it and seeing whether it has better performance on emulator load or not.
Solution 4: Update Your System OS
Many users have reported that after they have updated their device, Android emulators begins to run slow. But there are solutions as well that includes:
- When running Android emulator on Windows, check whether Windows updates are done or not. Because after uninstalling these update, several users have told that their Android emulator performance was improved. And at the same time, several users have reported about improved emulator performance after they have installed KB4015438 Windows update.
- Run the emulator via -gpu swiftshader, -gpu angle, gpu guest modes.
- If your system has both Intel HD 4000 GPU and discrete GPU then you should disable HD 4000GPU just to ensure you are already using discrete GPU.
- Also make sure that if you don’t have IPv6 connection then router should not use IPv6 address
Doing all these changes, now you might get rid of app keeps freezing or stopping on Android emulator.
Solution 5: Free Up RAM And Commit Charge
Whenever emulator starts, it checks the Android OS RAM. The emulator on Windows ask to account full size guest memory at beginning and when such thing happens then some request increase current commit limit. In such situation, Windows fail to guarantee about worst case working set will fit on physical RAM or pagefile and hence, emulator starts to fail.
Sometime, user come across failure to start emulator due to exceed in commit limit. However, this can be reduced by several ways such as:
- Free up physical RAM before you start the emulator simply by closing all applications
- Disable all third party memory management and compression utilities.
So all these are the best solutions for app keeps freezing on Android emulator.

Debugging
If you want to do more in-depth debugging in your code, you can setup breakpoints in your code by clicking on the left side pane and then clicking on Run->Debug. You can also click on the bug icon if you've enabled the Toolbar (View->Enable Toolbar):
Android Studio also provides a built-in decompiler. You can also use Navigate->Declaration within the IDE and set breakpoints even within classes for which you may not necessarily have the actual source code. Notice the warning message at the top and an example of a screenshot of setting a breakpoint of a class defined in a JAR file below:
If the debugger isn't working, check the guide section below to get things running again.
Network Traffic Inspection
If you wish to inspect network traffic, see this guide on how to troubleshoot API calls. The networking library you use determines what approach you can use.
Database Inspection
Also, the Stetho project can be used to view your local SQLLite database. See this guide for more details.
LogCat
Android Studio contains a panel to receive logging messages from the emulator, known as LogCat. If you are not seeing any log messages, click on the Restart icon .
Resetting adb
If you are having issues trying to connect to the emulator or see any type of 'Connection refused' errors, you may need to reset the Android Debug Bridge. You can go to Tools->Android->Android Device Monitor. Click on the mobile device icon and click on the arrow facing down to find the Reset adb option.
Virtual Device Manager
Unable to delete emulator getting 'AVD is currently running in the Emulator'
Open the Tools => Android => AVD Manager and select virtual device that you want to delete. Click on the down arrow at the end and select the [Show on Disk] option which will open the emulator directory. Inside the [Your Device].avd folder, locate any *.lock files and delete them. You can now delete the emulator. See this stackoverflow post for more details.
Android Studio Issues
Android Studio is Crashing or Freezing Up
If Android Studio starts freezing up or crashing even after rebooting the IDE or your computer, your Studio has likely become corrupted. The best way to resolve this is to clear all the caches by removing all the following folders:
and then uninstall Android Studio and re-install the latest stable version. This should allow you to boot Android Studio again without errors.
Android Studio Design Pane isn't loading properly
If you find yourself opening up a layout file and not seeing the design pane rendering correctly such as:
We can try the following steps to get this functioning again:
- Try changing the API version selected in the dropdown and try a few different versions
- Click the 'refresh' icon at the top right of the design pane
- Select
File -> Invalidate Caches / Restartand restart Android Studio
You may need to install the newest version of Android and select that version within the dropdown for the pane to work as expected.
Seeing Unable to execute dex: method ID when compiling
This might also show up as Too many field references: 131000; max is 65536. or com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536 or Error:Execution failed for task ':app:dexDebug' in the build console. This error occurs when the total number of references within a single bytecode file exceeds the 65,536 method limit. This usually means you have a substantial amount of code or are loading a large number of libraries.
If you've crossed this limit, this means you've loaded too many classes usually due to third-party libraries. Often the culprit is the Google Play Services library. Open up your app gradle file and look for this line implementation 'com.google.android.gms:play-services:X.X.X'. Remove that line and instead include the services selectively as outlined there. For example:
This can greatly reduce the number of classes loaded. If you've crossed the limit even with this change, we need to adjust our project to use a multidex configuration by enabling multiDexEnabled true in your gradle configuration and updating the application to extend from android.support.multidex.MultiDexApplication.
Seeing java.lang.OutOfMemoryError : GC overhead limit when compiling
You are most likely exhausting the heap size especially during compilation. Try to add inside this setting in your app/build.gradle:
You can also reduce the build time too by setting incremental to be true:
See this Google discussion article for more context.
Still not working? Try to increase the heap size of Android Studio.
- Quit Android Studio.
Create or edit a
studio.vmoptionsfile.- On Mac, this file should be in
~/Library/Preferences/AndroidStudio/studio.vmoptions. - On Windows, it should be in
%USERPROFILE%.AndroidStudiostudio[64].exe.vmoptions.
Increase the maximum memory to 2 Gb and max heap size of 1 Gb.
- On Mac, this file should be in
Start Android Studio.
Getting 'No resource found that matches given name.'
If you are using multiple layout folders and decide to rename any of your ID tags in your XML files, you may get 'No resource found that matches given name.' There is a current bug in how changes are detected in nested subfolders so your best option is to not use this approach until the problem is fixed. Otherwise, you will need to do a Rebuild Project so that the entire resource files can be regenerated and the build/ directories are fully removed. Note: Clean Project may not work.
Getting 'tooling.GradleConnectionException' errors
If you see org.gradle.tooling.GradleConnectionException errors, you may need to install a newer version of JDK (there have been reports of 1.7.0_71 having this issue). First try to restart the adb server first.
Getting 'failed to find Build Tools revision x.x.x'
If you're opening another Android Studio project and the project fails to compile, you may see 'failed to find Build Tools revision x.x.x' at the bottom of the screen. Since this package is constantly being changed, it should be no surprise that other people who have installed Android Studio may have different versions. You can either click the link below to install this specific Build Tools version, or you can modify the build.gradle file to match the version you currently have installed.
Android Studio Emulator Crashes Mac Os
Getting 'com.android.dex.DexException: Multiple dex files define'
One of the issues in the new Gradle build system is that you can often get 'Multiple dex files define' issues.
If a library is included twice as a dependency you will encounter this issue. Review the libs folder for JARS and the gradle file at app/build.gradle and see if you can identify the library dependency that has been loaded into your application twice.
If one dependency library already includes an identical set of libraries, then you may have to make changes to your Gradle configurations to avoid this conflict. This problem usually happens when there are multiple third-party libraries integrated into your code base. See Must-Have-Libraries#butterknife-and-parceler for more information.
Another error if you attempt to include a library that is a subset of another library. For instance, suppose we included the Google play-services library but thought we also needed to include it with the play-services-map library.:
It turns out that having both is redundant and will cause errors. It is necessary in this case to remove one or the other, depending on your need to use other Google API libraries. See this overview of the multidex issue on the Android docs.
Seeing Unsupported major.minor version 52.0 on some plugins
Some Android Studio plugins do not support Java 1.6 anymore, so it's best to confirm what version you are using. Inside Android Studio, click on About Android Studio. You should see the JRE version listed as 1.x.x below:
If you have multiple Java versions installed, you should make sure that v1.6 is not being used. Solutions include:
- Configuring JDK 8 as your default Java SDK within Studio. See this stackoverflow post for solutions.
- Reset your Android Studio cache and set correct gradle version as shown in this post.
On OS X machines, you can remove the JDK from being noticed. You can move it the temporary directory in case other issues are created by this change.
INSTALL_FAILED_OLDER_SDK error message
If your minSdkVersion is higher than the Android version you are using (i.e. using an emulator that supports API 19 and your target version is for API 23), then you may see an error message that appears similar to the following:
You will need to either lower the minSdkVersion or upgrade to an Android emulator or device that supports the minimum SDK version required.
Seeing java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation
You have a third-party library reference defined twice. Check your app/build.gradle for duplicate libraries (i.e. commons-io library defined for 1.3 and another one using 2.4).
Debugger Isn't Working: Breakpoint In Thread is Not Hit
You might notice that the debugger does not always work as expected in background threads such as AsyncTask or when using networking libraries to send network requests. The debugger breakpoints are a little bit finicky when configured to stop outside the main thread.
In order for some of these breakpoints in the callbacks to work, you have to set them after the debugger has been initialized and not before. If you have already set the breakpoints before, then you have to reset them after the debugger starts. One common strategy is to set the breakpoint on the main thread and then, once that has been hit, add the breakpoint on the background thread.
Debugger Isn't Working: Disconnected or Client not ready yet
This is usually a signal that the emulator instance is not properly connected with ADB and Android Studio. There are a few steps to try:
Android Studio Emulator Crashes Mac
First, try uninstalling the app from within the emulator and then restarting the emulator completely. Try debugging again now.
Next, close the emulator again and also restart Android Studio. Start Android Studio and reload the emulator. Then try debugging again.
If you are using official emulator, try using Genymotion or vice-versa. Then try debugging again.
Open up
Tools => Android => Android SDK Managerand see if there are any updates to the platform or SDK tools. Update any suggested changes within the manager and then restart your emulator and Android Studio. Then try debugging again.
