You better make sure the apk files-names do not have spaces or you'll have to escape the file-names. Generally speaking, use the install-multiple while escaping the package name (your apk files), Since you'll be saving some overhead connection-time over each command connecting/disconnecting to your device's modem, Which is prefered over installing one-by-one, push this package file to the device and install it You can either use (from ADB help): adb install-multiple
