ADBKeyBoard

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.

<pre> usage: input [text|keyevent] input text <string> input keyevent <event_code> </pre>

But you cannot send unicode characters using this command, as it is not designed to use it this way. <br /> Reference : http://stackoverflow.com/questions/14224549/adb-shell-input-unicode-character

<pre> e.g. adb shell input text '你好嗎' is not going to work. </pre>

ADBKeyboard will help in these cases, especially in device automation and testings.

Usage Example:

<pre> 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. * For Mac/Linux, you can use the latest base64 input type with base64 command line tool: adb shell am broadcast -a ADB_INPUT_B64 --es msg `echo -n '你好嗎? Hello?' | base64` * For Windows, please try this script (provided by ssddi456): https://gist.github.com/ssddi456/889d5e8a2571a33e8fcd0ff6f1288291 * Sample python script to send b64 codes (provided by sunshinewithmoonlight): import os import base64 chars = '的广告' charsb64 = str(base64.b64encode(chars.encode('utf-8')))[1:] os.system("adb shell am broadcast -a ADB_INPUT_B64 --es msg %s" %charsb64) 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' 5. Send meta keys To send Ctrl + A as below: (4096 is META_CONTROL_ON, 8192 is META_CONTROL_LEFT_ON, 29 is KEYCODE_A) adb shell am broadcast -a ADB_INPUT_TEXT --es mcode '4096,29' // one metaState. or adb shell am broadcast -a ADB_INPUT_TEXT --es mcode '4096+8192,29' // two metaState. 6. CLEAR all text (starting from v2.0) adb shell am broadcast -a ADB_CLEAR_TEXT </pre>

Enable ADBKeyBoard from adb :

<pre> adb shell ime enable com.android.adbkeyboard/.AdbIME </pre>

Switch to ADBKeyBoard from adb (by robertio) :

<pre> adb shell ime set com.android.adbkeyboard/.AdbIME </pre>

Switch back to original virtual keyboard: (swype in my case...)

<pre> adb shell ime set com.nuance.swype.dtc/com.nuance.swype.input.IME </pre>

Check your available virtual keyboards:

<pre> adb shell ime list -a </pre>

Reset to default, don't care which keyboard was chosen before switch:

<pre> adb shell ime reset </pre>

You can try the apk with my debug build: https://github.com/senzhk/ADBKeyBoard/raw/master/ADBKeyboard.apk
