Install apk to multiple Android emulators


$ ./adb install ~/my_app.apk error: more than one device and emulator - waiting for device -

Fix by installing to a specific device.

List devices

$ ./adb devices -l List of devices attached emulator-5554         device emulator-5556         device

Install to each device

$ ./adb -s emulator-5554 install ~/my_app.apk $ ./adb -s emulator-5556 install ~/my_app.apk


Fix "can't find 'emulator-5554' to install" by using the correct syntax / parameter order.

$ ./adb install -s emulator-5554 ~/my_app.apk => $ ./adb -s emulator-5554 install ~/my_app.apk
