Uninstalling existing application. Failures here can almost always be ignored.

D:\‏‏תיקיה חדשה\Android_ETC1>C:\NVPACK\android-sdk-windows\platform-tools\adb.exe uninstall com.daniel.vr
error: more than one device/emulator

Installing existing application. Failures here indicate a problem with the device (connection or storage permissions) and are fatal.

D:\‏‏תיקיה חדשה\Android_ETC1>C:\NVPACK\android-sdk-windows\platform-tools\adb.exe install vr_project-armv7-es2.apk
error: more than one device/emulator

There was an error installing the game or the obb file. Look above for more info.

Things to try:
Check that the device (and only the device) is listed with “ADB$ devices” from a command prompt.
Make sure all Developer options look normal on the device
Check that the device has an SD card.
Press any key to continue . . .

how can fix it?
