System Language¶
This chapter describes how to modify the system language and the default language at factory reset in Android.
Runtime Modification¶
The following methods allow you to change the system language during runtime. After a factory reset, the system reverts to the default language.
Via ADB command
Via System Settings
SDK Build Configuration¶
To permanently set the default language, you can modify the SDK source code. After building and flashing, the default language will be fixed.
Recommended Method¶
For example, on K1 (RK3568), add the persist.sys.locale property in the corresponding configuration file:
--- a/device/rockchip/rk356x/rk3568_t/rk3568_t.mk
+++ b/device/rockchip/rk356x/rk3568_t/rk3568_t.mk
+
+PRODUCT_PROPERTY_OVERRIDES += persist.sys.locale=zh-CN
For other boards, find the corresponding configuration file in the table below and add the same line:
| Model | SoC | SDK | Configuration File |
|---|---|---|---|
| K1 / K1B | RK3568 | rk-android13.0 | device/rockchip/rk356x/rk3568_t/rk3568_t.mk |
| K1 MINI | RK3568 | rk-android13.0 / rk-android14.0 | device/rockchip/rk356x/rk3568_t/rk3568_t.mk |
| K2B / K2C | H618 | h618-android12.0 | device/softwinner/apollo/apollo_p2.mk |
| K3 | RK3562 | rk-android13.0 | device/rockchip/rk3562/rk3562_t/rk3562_t.mk |
| K3B | RK3562 | rk-android13.0 / rk-android14.0 | device/rockchip/rk3562/rk3562_t/rk3562_t.mk |
| K5 / K5C | A133 | a133-android10.0 | android/device/softwinner/ceres-c3/ceres_c3.mk |
| K7 / K7C / K7S_K7F | RK3576 | rk3576-android14.0 | device/rockchip/rk3576/rk3576_u/rk3576_u.mk |
| K8 | RK3588 | rk-android13.0 | device/rockchip/rk3588/rk3588_t/rk3588_t.mk |
| K8D | RK3588S | rk-android13.0 / rk-android14.0 | device/rockchip/rk3588/rk3588s_t/rk3588s_t.mk |
| K9 | T527 | t527-android13.0 | device/softwinner/saturn/t527-demo/device-common.mk |
| K10B | A733 | a733-android13.0 | device/softwinner/jupiter/a733-demo-aiot/device-common.mk |
| K11C | RK3566 | rk-android13.0 / rk-android14.0 | device/rockchip/rk356x/rk3566_t/rk3566_t.mk |
| TX66 | RK3566 | rk-android13.0 | device/rockchip/rk356x/rk3566_t/rk3566_t.mk |
Alternative Methods¶
The following methods also work but have lower priority and are usually not necessary to configure.
Using persist.sys.language and persist.sys.country
--- a/.../device.mk
+++ b/.../device.mk
+
+PRODUCT_SYSTEM_DEFAULT_PROPERTIES += \
+ persist.sys.country=CN \
+ persist.sys.language=zh
Using PRODUCT_LOCALES
