ADB Change Language

Change locale (language) of your device via ADB (on Android OS version 8.0, 7.0, 6.0, 5.0, 4.4, 4.3, 4.2 and older). No need to root your device! With ADB (Android Debug Bridge) on your computer, you can fast switch the device locale to see how your application UI looks on different languages.

Usage:

- install this app

- setup adb connection to your device (http://developer.android.com/tools/help/adb.html)

- Android OS 4.2 onwards (tip: you can copy the command here and paste it to your command console):

adb shell pm grant net.sanapeli.adbchangelanguage android.permission.CHANGE_CONFIGURATION

- Language change example 1, Brazilian Portuguese:

adb shell am start -n net.sanapeli.adbchangelanguage/.AdbChangeLanguage -e language pt-rBR

- Language change example 2, French and English:

adb shell am start -n net.sanapeli.adbchangelanguage/.AdbChangeLanguage -e language fr,en

This tool is especially handy for developers who want to add locale switching to (test) automation. Tool works on all the latest public OS versions, verified on Android OS 8.0 (Oreo, Google Pixel XL) 7.0 (Nougat, LG G5), 6.0 (Marshmallow, Nexus 6 and Nexus 9), 5.0 (Lollipop, Nexus 5), 4.4 (Kitkat, Galaxy S5), 4.3, 4.2, 4.1 (Jelly Bean), 4.0 (Ice Cream Sandwich, Asus Transformer tablet).
