Paste text on Android Emulator
Solution 1:
In a terminal, type adb shell input text 'my string here. With some characters escaped like \$ that'
Note that an alternative method for including spaces in the text is to substitute %s for each space character.
Solution 2:
With v25.3.x of the Android Emulator & x86 Google API Emulator system images API Level 19 (Android 4.4 - Kitkat) and higher, you can simply copy and paste from your desktop with your mouse or keyboard.
This feature was announced with Android Studio 2.3
