Android Studio shows black screen when running - android

I have a problem when running the applications in Android Studio as everytime it shows only a black screen where it's written Android and that's all. Any ideas why it's doing this and how I can solve it?

1) Go to SDK Manager->Extra->intel x86 Emulator Accelerator (HAXM installer) and check is it installed or not? if it is not installed then install it.
2) Allow Virtualization in BIOS setting.
But i suggest you to use GenyMotion to run your Android Application. Here is link [https://www.genymotion.com]. It is FAST,SIMPLE and POWERFUL.

When the emulator isn't booting it's mostly a driver problem.
Make sure you have all your windows updates, since windows by default also updates essential drivers. This happenes more often when you have an illegal version of windows.
Or download driver software that automatically updates your drivers.
Also downloading the "Visual C++ Redistributable for Visual Studio"'s worked for me, but I did not try this whithout my full update.

Can't run Visual Studio Emulator

Formatted my computer with windows 8.1 pro and upgraded it to windows 10 pro, both x64.
Enabled Hyper-V on BIOS and on Windows Features, but no success. Disabled and enabled again, rebooted and nothing... Also reinstalled Visual Studio Emulator for Android and never works.
Always I get the error "You have been added to the Hyper-V Administrators security group. Please sign out of your computer for the permissions to take effect" when I try to run a android device.
What could I do for solve this?
Screenshots below:
You should install Intel HAXM instead of enabling Hyper-V for the Android emulator. Only the Windows Phone emulators require Hyper-V, and HAXM and Hyper-V cannot be active simultaneously, which means that enabling one disables the other.
Also, dealing with emulators from Visual Studio itself is not recommended as it proved to be messy and unrealiable. Instead, you should manage the entire Android SDK and its emulators from the Android SDK tools standalone installer (not Android Studio). Follow these instructions to install the Android SDK tools 24 standalone GUI and immediately update them to SDK tools 27, which includes the latest Android emulators.
Then, create the emulators from Android AVD Manager, and start your desired emulator. Whenever you deploy to emulator from Visual Studio, it will use the already running emulator, so you don't need to choose one from VS itself.

Android emulator hates me

Sorry for this title but I'm just so mad because not any of the emulators seem to be working for me. Here are the reasons:
Built-in Android Emulator - too slow, it won't even deploy the application, stuck at Starting emulator ..., mostly gets the error Emulator cannot be started with VS (unknown provider)
Genymotion - i thought this is my hope but the virtualbox for some reason gives me Blue Screen of Death hence not being able to use this really good, best recommended emulator
BSOD Technical Information: STOP: 0x0000003B (0x00000000c0000005, 0xFFFFF880010C9710, 0xFFFFF8800DFB8690, 0000000000000000)
XAP or Xamarin Android Player - uses VirtualBox as well, won't let me run the emulator, a dialog box appears saying Failed to start the virtual machine. This indicates you have just installed virtualbox and need to reboot your computer. Rebooted/restarted the computer a thousand times, same error.
This is too much pain for me as I'm still a beginner in Android Development but seems like it hates me so much.
Processor: Intel(R) Core(TM) i5-5300U CPU # 2.30GHz 2.30 GHz
RAM: 8.00 GB
System: Windows 7 64 bit
Btw, I'm working my Android app in Xamarin Visual Studio 2015.
Let me know if I missed any specific details.
Install Intel hardware accelerator manager (HAXM).
It can be downloaded using the android sdk manager. Once downloaded you have to run the installer manually. The installer is located in you android sdk folder, in /extra/Intel subfolder.
After it is installed, any android simulator using an x86 image will run full speed.
Also make sure HyperV is deactivated, and that virtualization is enable in the machine's bios.
Well, first it will be better to check out if all Android SDK packages were properly installed. To do that locate on your computer a software called "Android SDK Manager" and run it. It will shows the status of several different packages.
Check if you already have installed:
1) Android SDK Tools 24.4.1 and 24
2) Android N (API 21)
3) Intel x86 Emulator Accelerator (HAXM installer)
If you don't have installed, then do it selecting them and clicking on "install packages" button.
Restart Visual Studio and try to run a simple/demo app.

Androild Studio Emulator Not Launching: Intel Haxm Not Installed

I was trying Android Studio - successfully installed it but couldn't launch the emulator and the error message was Intel Haxm wasn't installed. I checked my setting and realized it was installed.
I tried to re-run it several times and the same thing happened.
I tried to install SDK 17 and the error was still there.
May I know what might be causing this? And how should we solve it?
Thank you.
You was created an AVD with Intel Atom system image, so make sure that your CPU is Intel. If yes, see this instructions about installing HAXM on your computer.
If HAXM won't to be installed, please make sure that your CPU is strong enough to use HAXM. Then, change the system image of your AVD to ARM-v7 or Armeabi.
System image also called with CPU type of the emulator on AVD.
Another option to run Android Apps on computer:
If you are not able to use Android Studio Emulator (at all after trying above given solutions), then you can use Genymotion. It comes with free as well as paid versions. You can download this software on your Windows/Mac/Linux based computer and configure it with Android Studio/Eclipse.
Watch this video for more details: Install and configure Genymotion with Android Studio
Genymotion is fast and reliable and also has latest (till Lollipop 5.0) android support and provides many emulator themes as well.
I hope this answer helps you if above mentioned solution doesn't work.

I can't install intel HAXM

I installed Android Studio and I had no problems with that. However, when I tried to run the emulator, it said that Intel HAXM was not installed.
So I found the installer, ran it, and it even though it said my laptop supports it, that it was not enabled. I went, enabled the Intel Virtualization Technology (VT-x), but I still got the same message.
I hear something about Hyper-V needs to be disabled, but when I go to Turn Windows features on/off, I cannot find it on that list.
Can someone help me with this?
Alright, so I did everything I could possibly find online, and nothing worked.
So I went to the Intel website, and I downloaded the HAXM installer that they provide (instead of using the one downloaded through Android Studio).
The installation actually went through with this installer and it was installed successfully. Then I open Android Studio, and the emulator finally loaded!
So, for anyone else having this problem, just download the installer directly from the Intel website.
Here's the link:
https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager
I think your problem was that you thought that the installer in Android SDK Manager would actually INSTALL the Intel HAXM. But the hook is that it WILL NOT INSTALL it. What it does is extracts the files needed for (really) install Intel HAXM.
I found that out when I got the same problem and then read this in Intel's web page:
Downloading through Android* SDK Manager
... Other steps ...
5) The SDK Manager will download the installer to the "extras" directory, under the main SDK directory. Even though the SDK manager says "Installed" it actually means that the Intel HAXM executable was downloaded. You will still need to run the installer from the "extras" directory to get it installed.
6) Run the installer inside the /sdk/extras/intel/Hardware_Accelerated_Execution_Manager/ directory and follow the installation instructions for your platform.
So all I needed to do was go to folder where my Android SDK was, opened that folder (sdk_location/sdk/extras/intel/Hardware_Accelerated_Execution_Manager) and run the silent_install.bat.
After this when I launched my emulator, it said this:
HAXM is working and emulator runs fast virt mode
and everything works as should!
You can also use some useful parameters with silent_install.bat:
-v Print HAXM version
-c Check VT/NX capability of the platform
-h Print usage
Make sure the emulator is not running while installing HAXM. Otherwise, there will be an error which you only see when using the standalone installer but not within Android Studio or IntelliJ Idea.
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
or
bcdedit /set hypervisorlaunchtype off
Other things you may need to do:
If using Avast? disable Enable hardware-assisted virtualization under: Settings > Troubleshooting
bcdedit /set nx AlwaysOn
sfc /scannow and reboot
Important: After anything you try, Restart the PC and try to run the HAXM installation again
I faced this problem.I got the solution too.It will work.
Step 1: Go to your BIOS settings and check that INTERNET VIRTUAL TECHNOLOGY is Enabled or Disabled.
And make sure HYPER V is disabled.
To disable it :
a)Go to Control Panel
b)Click on Programs(Uninstall a Program)
c)Then click on Turn Windows features on or off , then look for HYPER-V and untick it. And Restart.
If disabled then enable it.
Step 2: Try to install Intel HAXM now and restart. If It shows same problem again.
go to Step 3.
Step 3: You have to disable Digitally Signed Enforcement. To disable it permanently you have to make sure that Secure Boot option is disabled in your system.
How to check ?
Answer is given in the following link. I found it in Internet.[Thanks whoever made that blog]
link : http://www.windowspasswordsrecovery.com/win8-tips/how-to-disable-uefi-secure-boot-in-windows-8-1-8.html
Step 4: Now restart again.
To disable driver signature enforcement permanently in Windows 10, you need to do the following:
1.Open an elevated command prompt instance.
2.Type/paste the following text:
`bcdedit.exe /set nointegritychecks on`
or Windows 10
`bcedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS`
Windows 10 disable driver signature enforcement
Restart Windows 10.
*If you somehow want to enable it again:
1.Type/paste the following text:
`bcdedit.exe /set nointegritychecks off`
<==||=====>For me who have an AMD Processor:<=====||==>
1. Click on the windows button in the bottom left hand corner
2. Look for Enable/Disable Windows features
( Just type : "windows features", it will appear)
3. And contrary to the other posts here, enable Hyper-V and Windows Hypervisor Platform
Thanks.
I probably tried all the solutions mentioned above but all in vain.
To summarize, I did:
I enable the virtualization going to BIOS setting.
Uncheck Hyper-V option by going to Turn Windows features on or off.
Download HAXM directly from the website https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager and install it.
Uninstall and reinstall Android Studio.
Copy the HAXM from my another system where HAXM was working fine, from the location C:\Users\UserName\AppData\Local\Android\Sdk\extras\intel
Nothing worked for me.
What worked for me:
I noticed the issue "unable to run mksdcard sdk tool" when I try to download SDK platform.So after some research, I found some SDK tools such as mksdcard.exe require Microsoft Visual C++ runtime 2015-2019. So based on my system type,(for me it was x64) I downloaded the latest Microsoft Visual C++ Redistributable for Visual Studio 2019 from the link https://visualstudio.microsoft.com/downloads/.
Detailed answer given here:
Android Studio install failed - unable to run mksdcard sdk tool in Windows
After downloading and installing Visual C++ ,the error "unable to run mksdcard sdk tool" was fixed, also when I try to install HAXM after this, it was install successfully. Everything was fine. I was also able to create AVD now(which was also a problem when HAXM was not install).
How I solved this problem:
Step-1: Downloaded the Android Studio and installed it. But it failed to install HAXM.
Step-2: Then ran the AVD. Then it prompts to create a virtual device. But it also failed.
Step-3: I downloaded the latest HAXM from intel's GitHub source. From here github.com/intel/haxm/releases/latest
Step-4: Then installed HAXM manually. Documentation is here: Installing Standalone Intel HAXM on Windows
Step-5: Then again tried to create a virtual device of Pie. It successfully created it.
But if your Step-5 fails anyhow, there may another solution: When downloading the .zip file, it will show you the SDK path and also the source path of the .zip file. So you can manually download the .zip and can place it to the SDK path folder. Then again can try to create the virtual device.
This is what worked for me -
Enable Virtualiztion through BIOS (F10-> System Configuration -> Virtualiztion Technology)
Depending on your hardware, firmware and BIOS configuration utility the option to enable may be named something else or steps may differ.
There is a free software called "Piriform Speccy" which gives information about your machine, which among other things can also be used to check if virtualization is enabled or not on your machine (see screen cap).
Download HAXM intaller from Intel site. https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager
If using avast, disable "Enable hardware-assisted virtualization" under: Settings > Troubleshooting by unchecking.
Do a hard boot (power button) just to be safe.
Option 1: Go to Android SDK Folder --> Extra --> Intel and double click on HAXM installer and install it manually.
Option 2: If you do not have latest version of HAXM then you can open sdk manager in android studio and download it.
Option 3: Download HAXM intaller from Intel site. https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager
Download HAXM form this link download HAXM .Unzip it and you will see a msi installer file and install it.Then you will see no longer HAXM is not installed while creating your emulator.
Install Intel HAXM from Github.
It requires you to Disable the Hyper-V technology. To disable it follow instructions from Microsoft website.
You are Good To Go Now.
For HP Ultra book with windows 7 enabling hyper-v through bios worked for intel haxm problem.
For enabling hyper-v:-
F10-> Bios advanced setting-> device configurations->enable Hyper-V then install.
It will work.
I've figured out.
Try to disable Security Boot Control in BIOS options: http://remontka.pro/secure-boot-disable/ (sorry for russian examples)
Or try to start system without Digital signature (only for one loading).
I had had many unlucky attempts with 'HAXM installer, before I disabled this line.
At the beginning I thought that's because Windows 10 Home was installed, and there're many limits.
If Nothing Helps then it means Device Guard and Credential Guard are using the virtualization. I had to disable them by downloading and running the following script from microsoft site.
DG_Readiness_Tool_v3.5.ps1 -Disable
You may need to run this first if it doesn't allow to run the command
Set-ExecutionPolicy Unrestricted
Once you do it, you need to restart and confirm disable both when asked just before boot.
hope it helps!
Note: this is not an answer because I could not find a solution. But I think the information may be useful for others (and it wouldn't be practical as a comment).
I have tried all of the steps detailed in the various docs but I could not get Android Emulator to work on my AMD Ryzen 7 :(
Most answers work only for Intel CPUs.
If you have an AMD CPU (like me, an AMD Ryzen 7) you need to know about some restrictions and you have to use WHPX instead of HAXM.
I found this on MS's site: Because the Android emulator currently supports AMD hardware acceleration only on Linux, hardware acceleration is not available for AMD-based computers running Windows.
Fortunatelly there is a way to make it work but configuring hardware acceleration for an AMD CPU is a bit more complex:
Requirements and recommendations:
- AMD CPU recommendation: AMD Ryzen CPU
- Android Studio 3.2 Beta 1 or higher
- Android Emulator version 27.3.8 or higher
- Windows 10 with April 2018 Update or higher
To use WHPX acceleration on Windows, you must enable the Windows
Hypervisor Platform option in the Turn Windows features on or off
dialog box. For changes to this option to take effect, restart your
computer.
Additionally, the following changes must be made in the BIOS settings:
- AMD CPU: Virtualization or SVM must be enabled.
Note that there are further restrictions as well:
You can't run a VM-accelerated emulator inside another VM, such as a VM hosted by VirtualBox, VMWare, or Docker. You must run the emulator
directly on your system hardware.
You can't run software that uses another virtualization technology at the same time that you run the accelerated emulator. For example,
VirtualBox, VMWare, and Docker currently use a different
virtualization technology, so you can't run them at the same time as
the accelerated emulator.
Some more info: Android Emulator - AMD Processor & Hyper-V Support
This recommendation did not help either:
Please note: More recent versions of the emulator (27.2.8, 27.3.0, or
later), require an emulator flag while the feature is in the preview.
To do this, create or edit the file
C:\Users\.android\advancedFeatures.ini and add the
line “WindowsHypervisorPlatform = on”, or start the emulator from the
command line with “-feature WindowsHypervisorPlatform”.
For me who has an AMD Processor:
Click on the windows button in the bottom left hand corner
Look for Enable/Disable Windows features (just type : "windows features", it will appear)
And contrary to the other posts here, enable Hyper-V and Windows Hypervisor Platform
THE SHORT ANSWER:
Disable Microsoft Defender Application Guard
None of the answers helped me. Also, most of the answers here were addressed elsewhere online. I spent hours trying to solve this problem. After much hesitation, I decided to go on a hunch. I was suspicious about msinfo32.exe showing a Hypervisor was running, but it would not provide additional detail. I went into the services manager. I saw an instance of a hypervisor service was running, I went to disable it. Before disabling, I was asked if I am sure and was informed that a couple of other services would stop. One of the other services was Microsoft Defender Application Guard for Internet Explorer. I disabled this and FINALLY after hours of research on this topic was able to install Intel HAXM for Android Studio on my i5-4430 with Z87 chipset.
It was not enough to merely disable Hyper V and Windows Hypervisor Platform.
It should prompt you to install HAXM when creating a new virtual device:
Tools > Android > AVD Manager
It will install through Android Studio automatically.
If you are using windows then edit your AVD config to ARMEABI image instead of X86, Also using ARM will give better performance. HAXM installer is required only if you use X86 image.
I think that you would install Android SDK files not in (your PC)\Appdata\Local\Android\sdk (default Path). Also there was nothing when you double click 'intelhaxm-android.exe' file.
If it was, Browse (your PC)\Appdata\Local\Temp\intel\HAXM\6.0.3(yyyy-mm-dd_hh_mm_ss) (or silent), then you must see 'hax64' (or hax) file, and simply invoke this file.
Enter with Administrator user.
First, you must enable it
http://www.ghacks.net/2014/11/12/how-to-enable-the-hidden-windows-10-administrator-account/
Install it from C:\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-andoid.exe
And login with your user. It work for me.
Good description here: https://developer.android.com/studio/run/emulator-acceleration.html
You may check current HAXM status with following command:
sc query intelhaxm
If you use Windows 10 Home, all issues about Hyper-V is irrelevant for you as it is not supported (Pro is required) and you will not have conflicts :)
Remark: trying to update HAXM to latest version incidentally removed it, but then can't update with SDK manager, as it shows that latest version 6.1.1 is unsupported for Windows (seems configuration is broken, found 6.1.1 for Mac and 6.0.6 for Windows only inside)
So would recommend manually download HAXM and install as described:
copy to sdk_location/sdk/extras/intel/Hardware_Accelerated_Execution_Manager and run the silent_install.bat
After some trials, knowing that I had all the factors stated in this thread and other threads properly configured, I still got this error in Android Studio.
Even after installing externally, it seems Android Studio could not discover that HAXM is already installed, unless it gets to install it itself.
As a solution that worked for me, under User\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager which android has downloaded when attempting to install HAXM, click the installer and uninstall the software, then re-try from Android Studio to install it, it should work now.
I tried the following:
1. Directly installed HAXM from Intel
2. Tried multiple times to un-install and re-install Android Studio with same default paths in C drive.
3. Un-install various other software including QEMU which also uses HAXM, which might have been interfering with Android recognizing HAXM.
Solution was:
1. To un-install Android Studio and install it on D drive including the SDK. This solved the problem.
I installed Android Chipmunk 2021.2.1 and tried to install HAXM through the SDK manager. It failed first because I was running an emulator. However, one other thing I noticed is that when you first run the installer, it creates the folder for the HAXM install. Then, when the memory allocation dialog pops up, it tries to create the folder again. Since the folder already exists, it appends a "2" on the end of a new one. What I did is watched the install folder and when it creates the folder the first time I deleted it before continuing. I then continued with the install and it created the folder again and completed successfully. It seems there is a bug in the new SDK installer for HAXM
If you are using windows, Hyper-V works via AMD not HAXM.
Try the following: on Android, Click SDK Manager ==>SDK Platforms ==> Show Packages ==>ARM EABI v7a Systems Image.
After downloading the systems image, go to the AVD Manager ==> Create Virtual Device ==> choose device (e.g. 5.4 FWVGA") ==> Marshmallow armeabi v7a Android6 with Google APIs ==> Change the AVD name to anything (eg. myfirst)==> click finish.
If you have all gone through this and it still doesn't work and "systeminfo.exe" shows hypervisor is detected then disable Containers in Windows Features. After that all went well.
None of the suggestions worked on their own.
Here is what worked for me:
chmod -R 777 $ANDROID_HOME
Then try to install it via android studio -> sdk manager. If its not there, reinstall latest version of Android studio over your current installation. HAXM will show up in SDK manager after that.
If you do not have ANDROID_HOME set, then YOU are part of the problem.
The value of it can be found inside Android Studio project structure. On MAC, just type CMD ; and look at SDK Location on left.
Simply run chmod -R 775

Visual Studio Android Emulator won't run application

I recently got into Xamarin development. I have a lot of experience in Xcode making iOS apps and the iOS side was very straight forward. Now I'm trying to implement Android. I downloaded a Hello World example to get my bearings. When I run it I have no problems getting the simulator to show up (MonoForAndroid_API_10 and MonoForAndroid_API_12) but the actual application doesn't run, and does not show up anywhere on the simulator. Essentially whenever I use run or run with in Xamarin on Android, it pulls up a fully functioning, albeit empty simulator.
How do I get my application to run on the emulator?
Like the other commenters, this is most likely just a symptom of slow emulator on your machine. I'm running Xamarin-Android development on my 2010-era OSX machine in mavericks with 8GB RAM, and it is slow-slow-slow, but usable. Try to find the Intel x86 speeds improvements (look for HAXM) and you will find that the emulator will be much much faster.
And yeah, get a real handset and plug it in to your computer: always much faster than emulation.
later edit Get Genymotion for Mac OSX or for PC/Windows or PC/Linux. It's way way way faster than the other emulators. I have since found that this is as fast, or faster, than running the App on my connected Android phone. It's certainly simpler in not having to have the device plugged into one of my USB ports, and allows me to code and test on the train. http://www.genymotion.com/
Don't know if my issue was the same but finally this troubleshooting helped me to run emulator https://msdn.microsoft.com/en-us/library/mt228282.aspx#ADB.
I was missing key Android SDK Tools with string value Path in registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node
I've created it manually and it worked.
UPDATE
Before I got the issue with running emulator, I couldn't see it in Visual Studio. The reason was I've installed VS Android Emulator through standalone installation, not through VS Installer. It had to be installed there as well.
I had the similar issue, and then I deleted the existing device simulator and reinstalled again and it started working.
As I use a different SDK, in my case
Go to Tools > Options > Xamarin and set the Android SDK path.
Sometime Visual Studio changes this configuration;
2020 Update:
I followed the most voted comment, however, with Visual Studio 2019 updated recently, the steps have changed a little. Here is what previously worked:

Previous instructions image
WHAT TO DO INSTEAD
a. Go to Tools located at the top of the VS window, Get Tools and Features, go to Individual components, using the search tool in the pop up box, search "emulator", once you get the result, make sure both Google Android Emulator (API Level 25)(local install) and Intel Hardware Accelerated Execution Manager (HAXM) (local install) are both checked.
b. Close the solution(s) and restart VS then reopen the solution(s).
c. To deploy the app on the emulator, click Start button to spin up the emulator, left click on your Android project, then click Deploy. You should be able to see your app on your emulator's app menu.
Updated Instructions image
Worked for ME
Sometimes you close the android Emulator but not POWEROFF the Emulator.
this problem happens when emulator shutdown un-properly.
Restart Your EMULATOR
First start your emulator
Then restart your emulator by pressing down the power button and select restart option in your android emulator.
I enabled Hyper-V acceleration based on microsoft documentations: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration?tabs=vswin&pivots=windows#accelerating-with-hyper-v
Basically you need to turn on these two windows features from the control panel (Turn windows features on of off):
Hyper-V.
Windows hypervisor platform.
then from visual studio go to: Tools >> Android >> Android SDK manager >> Tools >> make sure that "Android emulator" version is 27.0.1 or higher, if not, you will find in the same screen a button below to update it.
I did this on windows 10 64-bit, with VS 2017 Community 15.9.5
