默认启用 WLAN 热点

核心方法打开关闭 WLAN 热点从 SystemUI 中的 qsTile 快捷开关中提取

既然要默认启用这里选择加到 KeyguardUpdateMonitor.java 中，监听开机广播

WLAN 热点保持开启，休眠不关闭

核心方法通过 adb shell dumpsys window | findstr mCurrentFocus 指令追踪到设置界面为

mCurrentFocus=Window{ffb4936 u0 com.android.settings/com.android.settings.Settings$TetherWifiSettingsActivity}

从 TetherWifiSettingsActivity.java 中得到

0 始终开启 1 空闲5分钟后关闭 2 空闲10分钟后关闭

WLAN 热点默认名称和密码

可通过 prop 值灵活配置默认名称和密码

frameworks/opt/net/wifi/service/java/com/android/server/wifi/WifiApConfigStore.java

     private WifiConfiguration getDefaultApConfiguration() {
         WifiConfiguration config = new WifiConfiguration();
-        config.SSID = mContext.getResources().getString(
-                R.string.wifi_tether_configure_ssid_default) + "_" + getRandomIntForDefaultSsid();
+        //config.SSID = mContext.getResources().getString(
+        //        R.string.wifi_tether_configure_ssid_default) + "_" + getRandomIntForDefaultSsid();
+        config.SSID = android.os.SystemProperties.get("persist.temp.wifiap.ssid", "WlanAP");
         config.allowedKeyManagement.set(KeyMgmt.WPA2_PSK);
         String randomUUID = UUID.randomUUID().toString();
         //first 12 chars from xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx
-        config.preSharedKey = randomUUID.substring(0, 8) + randomUUID.substring(9, 13);
+        //config.preSharedKey = randomUUID.substring(0, 8) + randomUUID.substring(9, 13);
+        config.preSharedKey = android.os.SystemProperties.get("persist.temp.wifiap.key", "123456789");
         return config;
     }
