A useful shell script that wraps Android adb commands when multiple devices or emulators are connected. The script will prompt for a device or emulator to run the command against, if it detects multiple devices / emulators.
#!/bin/bash
# This is a wrapper for adb. If there are multiple devices / emulators, this script will prompt for which device to use
# Then it'll pass whatever commands to that specific device or emulator.
# Run adb devices once, in event adb hasn't been started yet
BLAH=$(adb devices)
# Grab the IDs of all the connected devices / emulators
IDS=($(adb devices | sed '1,1d' | sed '$d' | cut -f 1 | sort))

Method for animating Android fragment positions during a add/replace/remove transition using custom properties. This method does not require subclassing target views with additional setter methods, but instead requires subclassing the fragment...something you are likely already doing.
/**
* An example of adding these transitions to a Fragment. This simple
* version just applies opposite transitions to any Fragment whether it is
* entering or exiting view. You can also inspect the transit mode parameter
* (i.e. TRANSIT_FRAGMENT_OPEN, TRANSIT_FRAGMENT_CLOSE) in combination to do
* different animations for, say, adding a fragment versus popping the back stack.
*
* Transactions without an explicit transit mode set, in this example, will not
* animate. Allowing the initial fragment add, for example, to simply appear.
