I am a newbie in Android Studio and I can't test my programs. Before using this I succesfully tested my android programs in eclipse.
After reading some questions in similar context I created a new emulator from
Tools-android-AVD Manager
But when I run the program it says No USB devices or running emulators detected(in select deployment target). How can I fix this
Try enabling USB Debuuging in the Android emulator itself, like you would do it on a real device. Settings-> Developer options-> enable USB Debugging.
Try this in android studio menu
Tools
-->
Android
-->
Enable ADB Integration
if is is already Enabled try to disbale and reenable this works most of time for me.
Try starting the emulator before opening Android Studio.
On Mac OS, I ran into this when JAVA_HOME was set incorrectly on a new machine I had just set up.
Resolved by:
Running java --version showed a pop-up that the JDK was not installed. I clicked the More Info button which took me to a download site.
Downloaded, and extracted to ~/tools/jdk-15.0.1.jdk
In .bash_profile set JAVA_HOME with full explicit path.

Sometimes wipe data helped.
if emulator launched you must close emulator,
open device manager -> open menu needed emulator -> wipe data->
you can launch emulator
You need to try to find a very small fragment (small Emu rectangle right in the center of the screen) (minimized emulator window) and enlarge it in all directions :)
Save your project to git
Wipe it from your computer
clone it
Open it with android studio
This steps work for me
Go to tools->android->AVD manager->then you can see the Android virtual devices.
If you dont have any devices,at the bottom shows create virtual device button then create new Virtual device,If you face issue i'll help you !
I have the latest Android Development Tools and SDK Tools (Revision 21.1) and cannot seem to enable the keyboard normally seen on the right side of the emulator. I also cannot seem to find the relevant settings inside the Edit Device dialog. Any help here?
You can also issue a command from the keyboard. http://developer.android.com/guide/developing/tools/emulator.html
And If you enter manual resolution in AVD it will not show keyboard just select any default resolution keyboard will start showing up
After updating SDK tools rev to 20, Android emulator doesn't take keyboard input from my desktop keyboard. When press a key of the desktop keyboard, the emulator will dead and I have to kill its process.
Android emulator also didn't take keyboard input from emulator own keyboard. But I have fixed this by following the steps in Android emulator doesn't take keyboard input - SDK tools rev 20.
Does anyone have some suggestions?
while creating/edit avd you need to mention the keyboard support.
An Avd manager , select you Emulator (Right side)---> Edit--->
Hardware(right side) ---> new---> property ---> Keyboardsupport -->
yes
Open Android Virtual Device Manager
Select Your AVD
Edit
Hardware -> New (Open Property Window)
Select Keyboard Support and Click on Ok
Now Make it True
I mean I can't type from my laptop keyboard into android emulator anymore.
Virtual and on-screen keyboards are working fine.
I had the same problem after upgrading to Tools version 20. I had to Edit the AVD to add an option as follows:
From Eclipse, Go to AVD Mananger.
Select the particular AVD and click on Edit
Go to the Hardware section, click on New.
Select the Property Name : Keyboard Support
By default, it is added with a value of 'no'. Just click on the value column and change it to 'yes'.
Click on Edit AVD again.
This will add a property hw.keyboard=yes in config.ini file for the AVD. And it should work fine from there.
I've upgraded the SDK tools to revision 20 (from 18) and since the upgrade, the emulator doesn't seem to accept input from laptop's keyboard. But only using the emulator's own 'soft' keyboard (that appears when an input field is focused).
I've tried reinstalling the SDK tools (and the whole SDK for that matter), uninstalled and reinstalled Eclipse Android plugins, re-created emulator devices. But none of that seem to help and its driving me mad. Its hopeless to key-in using a laptop's trackpad.
Has anyone encountered this problem?
Update
As of SDK rev 21 the Android Virtual Device Manager has an improved UI which resolves this issue. I have highlighted some of the more important configuration settings below:
If you notice that the soft (screen-based) main keys Back, Home, etc. are missing from your emulator you can set hw.mainKeys=no to enable them.
Original answer
Even though the developer documentation says keyboard support is enabled by default it doesn't seem to be that way in SDK rev 20. I explicitly enabled keyboard support in my emulator's config.ini file and that worked!
Add: hw.keyboard=yes
To: ~/.android/avd/<emulator-device-name>.avd/config.ini
Similarly, add hw.dPad=yes if you wish to use the arrow-keys to navigate the application list.
Reference: http://developer.android.com/tools/devices/managing-avds-cmdline.html#hardwareopts
On Mac OS and Linux you can edit all of your emulator configurations with one Terminal command:
for f in ~/.android/avd/*.avd/config.ini; do echo 'hw.keyboard=yes' >> "$f"; done
On a related note, if your tablet emulator is missing the BACK/HOME buttons, try selecting WXGA800 as the Built-in skin in the AVD editor:
Or by manually setting the skin in config.ini:
skin.name=WXGA800
skin.path=platforms/android-16/skins/WXGA800
(example is for API 16)
Confirmed. I had the same problem after upgrading to Tools version 20. I had to Edit the AVD to add an option as follows:
From Eclipse, Go to AVD Mananger.
Select the particular AVD and click on Edit
Go to the Hardware section, click on New.
Select the Property Name : Keyboard Support
By default, it is added with a value of 'no'. Just click on the value column and change it to 'yes'.
Click on Edit AVD again.
This will add a property hw.keyboard=yes in config.ini file for the AVD.
You also have to set hw.mainKeys = yes
In Android Studio, open AVD Manager (Tools > Android > AVD Manager).
Tap the Edit button of the emulator:
Select "Show Advanced Settings"
Check "Enable keyboard input"
Click Finish and start the emulator to enjoy the keyboard input.
Look in AVD Manager, select the AVD and click in Edit. In Hardware section: click in "New" and search for "Keyboard support" and add with OK button and set the value to "yes" and save changes with "Edit AVD"
Google wanted to give some more headache to the developers.
So, what you have to do now is edit your AVD and add "Keyboard Support" for it in the Hardware section and change the value to "Yes"
Add the following line
hw.keyboard=yes
to your AVD config file
~/.android/avd/<avd_folder>/config.ini
Restarting the emulator helps sometimes when typing is unavailable - despite keyboard input being enabled for your Android Virtual Device.
Just in case somebody finds it usefull.
I had a problem with the KEYCODE_DPAD_UP it belongs to the trackBall. to solve this change your avdfolder/config.ini hw.trackBall=yes and push DEL or F6
Here is some workaround that actually worked for me, it is the same solution as in the most popular answer - just
add hw.keyboard=yes to config.ini
but since this didn't work for me I additionally
renamed config.ini (any name will do) to something like consssssfig.ini
restarted emulator (obviously it didn't start)
renamed config.ini back again
(I am not sure if relevant) I added this new parameter (hw.keyboard=yes) at the beggining of config.ini file
Sometimes computer keyboard stops working on android emulator. Today I've noticed, that after pushing this button (that I marked with red arrow), keyboard starts working again (seems to be some issues with emulator window focus)
Look for the hidden .android folder in your user home folder. You might rename or delete this folder, recreate your AVD, and restart the emulator. It could be there is a .ini file in that folder that has that setting munged.
Recreating an AVD with the Hardware Keyboard + setting the boolean to true was the only solution that worked for me; the other two main solutions (terminal or editing an existing AVD via GUI) both resulted in software/emulator crashes on my Mac. Making a new AVD resulted in the keyboard working just fine.
I have used an emulator for API Level 23, which does not take keyboard input for installed apk.
So I have created new emulator for API Level 29, and then it works.
Following is the step to install new emulator.
Open "Android Virtual Device Manager"
Create new Virtual Device.
When you select a system image, please choose and download the last version(API Level29) on "Virtual Device Configuration" window
