Question

当我打开wifi开关时，该开关将自动关闭。我不知道是什么原因造成的。

这是日志

Answer 1

确保您具有此权限

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

并每次创建wifiManager

WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);

Android 8.0无法打开wifi开关
