I just installed Android Studio and I've been trying to figure out for the past 3 hours why it is that when I try to run my newly created project on a emulated phone it doesn't work. It's not even that the program doesn't work, it's that it freezes the moment I open it. I've tried uninstalling/reinstalling HAXM, SDK's for the phone, and recreating the phone / wiping the data on the phone and retrying, and nothing's worked so far. I'm wondering if anyone else has experienced this problem or knows what causes it? Please see picture to see what the problem is. P.S I'm using Android Studio on Windows. My system is beefy and should be able to run the emulator fine. I have Virtualization Enabled too.
This help me in getting it to work: switch off HyperV on Windows:
open Powershell as Administrator and run:
bcdedit /set hypervisorlaunchtype off
Reboot afterwards. Alternatively, run 'optionalfeatures' and select the HyperVisor platform to remove. To test if it really worked, run:
emulator.exe -verbose -avd <YOUR AVD NAME>
You can list the AVDs with 'emulator.exe -list-avds'.
Not my credits, but those of 'viet-quocnguyen'. See https://github.com/microsoft/WSL/issues/6471#issuecomment-770417782

Couldn't use x86 emulators, AVD manager shows warning "/dev/kvm is not found" and telling me to edit BIOS security setting to enable VT-x.
Re-installing HAXM resolved my problem
Steps:
Make sure SDK Manager -> Extras -> Intel x86 Emulator Accelerator (HAXM installer) is installed
Navigate to <sdk>/extras/intel/Hardware_Accelerated_Execution_Manager/
Run ./HAXM\ installation -u
Run ./HAXM\ installation
For MacOS users running Android Studio, when you get this error then try these steps to open up your privacy settings.
You can also follow the answer from Divakar on this post here - /dev/kvm not found on mac
Thank you Apple for pushing me with your dumb*** app review rules from iOS to android development
You just need to "start" the HAXM. You can do this following this steps:
Open the cmd.
Type sc query intelhaxm, click enter and check the STATE.
If state is 1 STOPED, type sc start intelhaxm and click enter to start the HAXM.
Check the STATE again and it should be 4 RUNNING now.
Finally, you are now able to create and use your AVD using a x86 emulator.
Alternatively, when you want to stop the HAXM you should type sc stop intelhaxm.
Hope this helps y'all.
I had a similar message in the emulators area in Android Studio 2.1.
My emulator for a certain API (think 21) worked initially fine and was fully accelerated, then installed a couple of other images (Nougat x86/64 etc) and suddenly started seeing /dev/kvm not found and NO emulator would boot up.
In My Case, re-installing HAXM sadly did not help, but rebooting my MAC did (go figure).
But, I also noted that if you have installed an emulator image but not the related SDK for the API (which makes sense), then you get a similar pop-up when starting the emulator, which makes you think it may be a HAXM / KVM issue, which its not.
Hope this helps someone.
Update Bios Setting
Power on the system and press[delete] key to enter BIOS [EZ Mode]
Press [F7] key to enter BIOS [Advance Mode] as below picture：
(If press [delete] key to enter [Advanced Mode] directly and then no need to press [F7] key any more)
Select [Advanced] page and click [CPU Configuration] item
Select [Intel(VMX) Virtualization Technology] item and set to [Enabled]
Press [F10] key and click [OK] ,the system will auto reboot
On Mac OS, After installing make sure to allow Intel HAXM under "Security & Privacy".
This was the only way I was able to run the Android Emulator :)
Reinstalling and restarting did not work for me. Instead, I had to start my Mac in Recovery Mode (restart & press ⌘+R until Apple logo appears). Then open terminal from Utilities drop down menu. Type and run:
csrutil enable --without kext
You will get some warnings and instruction to restart for the changes to take effect. Restart and the emulator will run this time.
Reference:
https://blog.celogeek.com/201708/672/android-studio-emulator-haxm-on-mac-os-high-serria-10-13/
Just go to terminal and type
sudo chown 777 -R /dev/kvm,
then type
sudo chmod 777 -R /dev/kvm.
And restart android studio
And that's it..
In some case it may happened that for every start of android studio you need to type this commands First and then start android studio.
I couldn't install mine because I had HyperV enabled on my machine. Removed it and I was able to install the HAXM from the following link:
https://github.com/intel/haxm
Either your CPU does not support virtualization, or it is disabled in the bios. Go into your bios and see if you can find a setting to enable it.
I tried reinstalling HAXM a few times but kept getting the errors.
In my case I actually had to go into Bios Settings and enable Virtualization.
It worked for me. Just in case this helps anyone.
I'm trying to run a java application on my rapsberry but I face some problems when I run this.
The application is successfully compiling and running, but I have a warning that seems to be the reason why it doesn't work well.
My application uses Telldus devices : The TellStick duo and I should see on the screen my devices and sensors to add them (it works on my computer), but the problem is that the application seems not recognize devices, and it could be caused by this warning :
ouput in my console
I (think) have understood that it can't find the file libTelldusCore.so, in the linux-arm folder. But after some research, I don't find the linux-arm folder.
Maybe I have did something bad, maybe I have forgotten something, I'm quite beginner with raspberry's systems.
So, if someone could help me, I would be very thankful.
Have you installed telldus-core library?
If you have not, try this, might help:
apt-.get install cmake libftdi-dev libconfuse-dev
wget http://download.telldus.se/TellStick/Software/telldus-core/telldus-core-2.1.1.tar.gz
tar -zxf telldus-core-2.1.1.tar.gz
cd telldus-core-2.1.1
cmake .
make
make install

I am trying to run my application on my Device from the Eclipse In windows.But my device is not detecting there in the eclipse.
My device driver is updated. In My device, I turned on "USB debugging mode" in Settings->Application->Development and also "Allow installation of non-market Applications" in Settings->Application->Development. And in Eclipse Target tab, selected "Always prompt to select device". My ProjectBuildTarget is not newer than my device's version. And tried adb kill-server also.
When i run adb devices it shows nothing in my command prompt.
How do I get Eclipse to load my app to my phone instead of my AVD?
When i tried it in my Mac machine It works perfectly..
Any solutions? Please suggest me..
Please try the following:
Go to settings in your phone
Go to storage menu
Select connect as MTP
Worked for me!
If you are using a MAC OS.... no need to install the Driver
But for Windows, try this http://developer.android.com/training/basics/firstapp/running-app.html#RealDevice
Debugging to phone
Please see the link above, the process is defined there from google.
close you AVD if its running, then re-plug your Mobile device, check in your phone USB debugging notification should come.
try deleting your AVD and leave your phone connected, then restart your IDE. Make sure you've downloaded the OEM USB drivers. If it still doesn't appear on the list, hit refresh then just run your app.
Like many I get this error but none of the solutions I found here did the job. I don't get this error when installing on an emulator, but I get this error with every app I'm trying to install.
This morning my phone went into save mode. After that I can't install an app anymore. The phone is already out the save mode though.
I don't get any errors in my logcat. Don't know what to do anymore. Could someone help?
It is similar to this question, but the only answer he got, I already tried.
Problem solved tanks to LisuBB
You can try to uninstall app from your device by executing
adb uninstall _nameofapp__
Try also to restart Android server
adb kill-server
adb start-server
and then try to install again.
check your phone's memory and see if you have enough memory . and restart it and check again.
Does the adb install work?
If so, try to install on an external sdcard through the cmdline.
When i create one apk from one machine and try to install into a device .it successfully get installed .But when i try to connect the same device to another machine and try to deploy same application from different machine.It doesnt allow me .I need to uninstall the application and then it works correctly .What is the issue for that .What i need to do to resolve this issue.
Thanks in advance.
Could you provide us with the output from console or the terminal prompt. There is usually an error, telling that the Application is already install, and you have to use the -r re-install option, OR that the apk has been signed with a diffrent certificate/key.
If its none of the above, please provide whatever error/output you get... If there is no more info on the output, please start the Dalvik monitor (ddms) and see what happens via the log...
