Hi friends there is problem when i run emultor in android studio in my lapto (aser aspire 5250) it shows me error msg "haxm is not installed" so i have cheked it and installed and now it shows as installed status but when i started emulator again it shows haxm is not instlled so i trace full path of sdk and tried to install haxm but at that time it shows me that your laptop does not support this so help me so that i can run my emulator in android studio for learning...
haxm uses your computer's virtualization engine to improve your emulator's performance. Try searching through your BIOS settings for some virtualization setting and make sure its enabled in there.
If there is no option or your computer doesn't have this feature, you can always disable the "Use Host GPU" option for your virtual device in its AVD settings.

I ran my app few times on my physical device, and it wroked perfectly. Now i'm trying to run the app on virtual device. Not showing any issues in every time, but the app was not installed on the virtual device. I want to emphasize that it worked before I tried on the physical device. When i press the "Run" window, it shows a message: "Launching 'app' on No Devices".
Then i tried to delet all the virtual devices and set new devices. Still the same message.
How can i fix it?
I also faced this issue. I wiped out data from AVD manager and it is working fine after wiping out data.
In my opinion, Android Studio has a problem in detecting virtual devices! check the AVD Manager window again, and also, check the module you want to run, then restart Android Studio.
Free up some space in the Avd folder. Delete unnecessary virtual devices, which might take LOT'S of space. You can also free up some space in general in drive.
Make sure Intel x86 Emulator Accelerator is installed
Make sure that the needed SDK is installed (for the virtual device you're using). Just see that the API of that virtual device is installed in: File -> Settings -> Appearance & Behavior -> System Settings -> Android SDK
Try quiting the emulator. Then in AVD Manager under your problem device click on the down triangle in Actions column and select 'Cold Boot Now'.
Running Android Studio 4.1.2, and this still seems to be an issue from time to time.
I found that running adb kill-server solved my issue, rather than the other suggestions here. No need to wipe data, cold boot, or restart Android Studio.
Do three things
check the Android virtual devicve (AVD) is installed . file-> setting ->appearance and behavior -> android sdk
Check the installed andoid is only used while running . I had installed android11 but my AVD was running noughat7.1.1
Wipe out data from AVD manager . Dont worry only temp memory will be vacated n no any installed sw will go.
After doing this mine problem of
"running on no device " is gone . Enjoy
EDIT: running Windows 8.1
Fully up-to-date Android Studio detects the phone (rooted Samsung Note 3 on 5.1). It's compatible. Developer Mode is active, USB debugging on, etc. Never had a problem connecting the phone for dragging and dropping.
However, whenever I try to put it on the phone...
Installation failed with message null.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application? (YES / NO)
No matter whether I press yes or no, I will get the same error.

I can use emulators (like Genymotion) just fine, it's just that having Android Studio / Emulators make my computer run hot at times, so I'd rather not do it if I can...
A solution I've tried is putting "android.permission.INSTALL_PACKAGES." into the Manifest but then I get a message that only system apps have that privilege.
I have another phone, a rooted S4 that running on 4.4.2. but whenever I connect that, the phone's UI crashes completely... that's a whole different issue.
Not sure if this is the problem, but make sure you have installed Samsung Kies, available here:
http://www.samsung.com/uk/support/usefulsoftware/KIES/
Without it you will not be able to run your Android Studio apps on Samsung devices.
First off, some rooting techniques screw a few things up so it could be that the root caused the problem.
Nonetheless, could you include which OS you are running Android Studio on?
Did you get the promt to authenticate. Maybe revoke authentocation from the developer options and try again.
I had the same problem one day and I solved it by reinstalling drivers on my computer for the device. Then when I run as administrator I am able to deploy my application without any problems.
Also try to uninstall the app from the command line.
~ adb uninstall com.yourpackagename
A few other commands to check if everything works:
~ adb devices
~ adb install com.yourpackagename
It's my first time looking at android studio and I came across a problem when trying to run my first app. I get this error:
I have tried to navigate to here to install it but I don't have a folder named intel for some reason:
USERNAME}\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager
I have also disabled enable hardware-assisted virtualization In avast because I read online that it can cause some issues when installing it.
Anyone know why I cant find the file to install it or know an alternative way of doing so?
Edit 1: I'm running x64bit windows 10 and trying to run my apps on Nexus 5 if that has any help.
Edit 2: I have now got the Intel folder and have the exe I need to install it but I get this error now:
When I check my bios however, it is enabled.
You have not downloaded HAXM with the SDK Manager. Start the SDK Manager and install it.
Hi so I am working through this book called Beginning Android Games because and I am having some problems with the Android 1.5 Android Virtual Device.
First the SDK for Eclipse (the program I am using) didnt have the 1.5 SDK for Android so I had it installed when you first try to run a AVD it asks has a checklist of SDK's that will be fetched and installed for you if you check the box. I did this, had the 1.5 SDK installed however when i try to run a AVD emulator using the 1.5 sdk i get a
(Failed to allocate memory: 8 This application has requested the Runtime to terminate it in an unusual way. please contact the application's support team for more information.)
type of error. But when I used the default 4.2 SDK for an AVD emulator the emulator showed up. I dont get what im doing wrong here.
Also in eclipse i have the Android ADT and SDK installed. In eclipse when i click on window then Android virtual device manager and I try to start a new emulator the 1.5 sdk i installed doesnt show. But when I click on window->sdk manager->tools->manage avds then my 1.5 sdk shows up and I can use it.
The problem was in the amount of ram for the virtual machine.
This following solution worked for me. In the following configuration file:
C:\Users\<user>\.android\avd\<avd-profile-name>.avd\config.ini
Replace
hw.ramSize=1024
by
hw.ramSize=1024MB
Go to Help -> Check for updates if there it shows some updates needed, then you can install them. May be it will work.
Lately I've been having problems developing Android applications. I'm in a Windows XP environment, using Eclipse 3.5 with the ADT tools. The emulator takes a bit of time to load, but that's always been normal. What is not normal is that when I go to run my program in the emulator at least 50% of the time Eclipse cannot connect to the emulator and either I have to use adb kill-server && adb start-server or restart the emulator or restart eclipse.
This has been happening with so much frequency that it is becoming very problematic. Should I put a newer version of eclipse (3.7) to replace this one? Any other things I can try?
Android development should be smoother as many people are developing Android apps these days.
Try Android x86. It works much more faster than Google Android emulator. Follow these steps:
Install VirtualBox.
Download iso-file that you need
Create a virtual machine Linux 2.6/Other Linux, 512 Mb RAM, HD 2 Gb. Network: PCnet-Fast III, attached to NAT. You can also use bridged adapter, but you need a DHCP server in your environment.
Install Android x86 on the emulator, run it.
Press Alt+F1, type netcfg, remember the IP, press Alt+F7.
Run cmd on your XP, change dir to your Android tools dir, type
adb connect <virtual_machine_IP>
Start Eclipse, open ADT plugin, find the device, enjoy!
