Android Virtual Keyboard Input via ADB
ADBKeyBoard is a virtual keyboard that receives commands from system broadcast intents, which you can send text input using adb.
There is a shell command 'input', which can help you send text input to the Android system.
usage: input [text|keyevent] input text input keyevent
But you cannot send unicode characters using this command, as it is not designed to use it this way.

e.g. adb shell input text '你好嗎' is not going to work.
ADBKeyboard will help in these cases, especially in device automation and testings.

- Sending Broadcast intent via Adb or your Android Services/Apps.
1. Sending text input adb shell am broadcast -a ADB_INPUT_TEXT --es msg '你好嗎? Hello?' * This may not work for Oreo/P, am/adb command seems not accept utf-8 text string anymore 1.1 Sending text input (base64) if (1) is not working. adb shell am broadcast -a ADB_INPUT_B64 --es msg `echo '你好嗎? Hello?' | base64` * You can use the latest base64 input type (together with Mac OS X/Linux's base64 command): 2. Sending keyevent code (67 = KEYCODE_DEL) adb shell am broadcast -a ADB_INPUT_CODE --ei code 67 3. Sending editor action (2 = IME_ACTION_GO) adb shell am broadcast -a ADB_EDITOR_CODE --ei code 2 4. Sending unicode characters To send 😸 Cat adb shell am broadcast -a ADB_INPUT_CHARS --eia chars '128568,32,67,97,116'
Switch to ADBKeyBoard from adb (by robertio) :
adb shell ime set com.android.adbkeyboard/.AdbIME
Switch back to original virtual keyboard: (swype in my case...)
adb shell ime set com.nuance.swype.dtc/com.nuance.swype.input.IME
Check your available virtual keyboards:
adb shell ime list -a
