Android settings使用详解之设置优先网络

settings是android提供用来修改系统设置的应用程序, 不需要root即可修改一些系统设置.

主要用法如下:

usage: settings [--user | current] get namespace key

settings [--user | current] put namespace key value

settings [--user | current] delete namespace key

settings [--user | current] list namespace

'namespace' is one of {system, secure, global}, case-insensitive

If '--user | current' is not given, the operations are performed on the system user.

修改系统默认的优先网络:

网络类型定义:

10: cdma, evdo, lte

20: lte, wcdma, td-scdma, gsm

21:wcdma, td-scdma, gsm,cdma, evdo

22:lte, wcdma, td-scdma, gsm,cdma, evdo

adb shell

settings put global preferred_network_mode1 22

settings put global preferred_network_mode 22,0
