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.
Instead of trying wipe data option, I tried Cold Boot Now option. It worked for me.
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.
Go to File -> Project structure -> Project -> select SDK version. Then you can see emulator name in android studio
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.
thanks for Yogesh Kuma
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 :)
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 !
