“在休眠状态下保持WLAN连接”设置成仅限充电时那项

请做如下修改:
alps\Frameworks\base\services\java\com\android\server\WifiService.java
private boolean shouldWifiStayAwake(int stayAwakeConditions, int
pluggedType) {
//Never sleep as long as the user has not changed the settings
int defaultValue = Settings.System.WIFI_SLEEP_POLICY_NEVER_WHILE_PLUGGED ;
//int defaultValue = Settings.System.WIFI_SLEEP_POLICY_NEVER; change
alps\packages\apps\settings\src\com\android\settings\wifi\AdvancedWifiSett
ings.java
private void initPreferences() {
if(Utils.isCmccLoad()){
value = Settings.System.getInt(getContentResolver(),
Settings.System.WIFI_SLEEP_POLICY,
Settings.System.WIFI_SLEEP_POLICY_NEVER_WHILE_PLUGGED);
// Settings.System.WIFI_SLEEP_POLICY_DEFAULT); change
}else{
value = Settings.System.getInt(getContentResolver(),
Settings.System.WIFI_SLEEP_POLICY,
Settings.System.WIFI_SLEEP_POLICY_NEVER_WHILE_PLUGGED);
// Settings.System.WIFI_SLEEP_POLICY_NEVER); change
}
