# To make the animation run slower, run:
$> animations-slow

# To return back to normal speed, run:
$> animations-normal

# To set to a custom speed, run:
$> animations-speed 5
# This sets the duration to 5x. 
# You can always verify the value in Developer Options if you do not know what the value of the duration is.

# When more than one device is connected and run `adb shell`:
$> adb shell
error: more than one device/emulator
# Then run one of the device functions to set the device and remove the need for the -s flag
$> adb-emulator 
Setting device to Emulator: emulator-5554
$> adb shell
generic_x86:/ # 
# This is the same as running `adb -s emulator-5554 shell` but persists the -s flag for the terminal session.

$> adb-text hello
# Sends the string "hello" over text input. 
$> adb-text <username>; adb-enter
# Great for typing username/passwords.
$> adb-text hello%sworld
# Send the string "hello world", note that %s is used for spaces.
$> adb-del 
# Sends the delete key event. Useful when needed to hit backspace to retype something.
$> adb-del 5
# Sends the event 5 times. Useful when needed to clear a larger chunk of text.

# Enable logging for a specific tag
# See https://developer.android.com/reference/android/util/Log.html#isLoggable(java.lang.String,%20int) for more details
