From what I gathered, you want to programmatically turn on Wi-Fi.
If so, first you need to add these to your AndroidManifest.xml:
<application>
.
.
.
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
</application>
Then you have the ability to use WifiManager, so your code would look something like the following, where this is your application Context:
WifiManager manager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
if(!manager.isWifiEnabled()){
manager.setWifiEnabled(true);
}

I want to create app functionality to turn on WIFI programmatically.
In android wifi.setWifiEnabled method was deprecated.
First, you need to ask the permission in the manifest file
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
Then in the activity file, you can disable wifi
WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);
boolean wifiEnabled = wifiManager.isWifiEnabled()
I have a problem banning a specific bssid. I can see there is a class called WifiNative that was in api 19 but not able to access it:https://android.googlesource.com/platform/frameworks/base/+/kitkat-release/wifi/java/android/net/wifi/WifiNative.java
Is there any other way anyone knows of to do this? Maybe via JNI? Any android system libraries that can be used? c,c++?
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
newWifiInfo = wifiManager.getConnectionInfo();
from there you can get the BSSID by doing
newWifiInfo.getBSSID()
then "blacklist" by turning off the wifi via
wifiManager.setWifiEnabled(false)
Also don't forget your permissions
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
If you want more control over your wifi state, you can use the following library to "sniff" your connection and other things

Thanks for helping with my Question!
Q : I'm working on an App, which has a Timed mechanism, and needs to change a Setting via Code (Ex: Turn Off WiFi, etc).. Is this possible to accomplish, obtaining Permissions for it via Manifest & Runtime Permission Requests, without needing Root?
I'm hoping I can simply do it via a Permission Request! Otherwise months of time lost :(
Thanks ahead of time for answering! Just need to know for sure.
well <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"> is not considered dangrous so you don't need to ask it on run time in marshmallow
All you need to do is declared it in the manifest like
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
and then in your activity you can enable and disable the wifi like this
WifiManager wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
// TO CHECK WEATHER ITS ENABLED OR DISABLED
boolean wifiEnabled = wifiManager.isWifiEnabled()
// TO ENABLE
if(!wifiEnabled) wifiManager.setWifiEnabled(true);
// TO DISABLE
if(wifiEnabled) wifiManager.setWifiEnabled(false);
Hope it helps
When i open wifi by code like this:
WifiManager wifim = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifim.setWifiEnabled(true);
it woks.
but the android system self open a confirm dialog like this:
Warning
The appliction WifiOpenTest is trying to trun on
Your WLAN connection.Do you want to allow this?
DISALLOW ALLOW
What I want to ask is can I open Wifi in source without show this dialog.
Thanks.
You need to add the following to your manifest
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
I am trying to create a widget for enabling and disabling the wifi.
if(myWifiManager.isWifiEnabled()){
System.out.println("Toggle Wifi Enabled going to disable");
myWifiManager.setWifiEnabled(false);
}
else{
System.out.println("Wifi Disabled going to enable ");
myWifiManager.setWifiEnabled(true);
System.out.println("WI: "+myWifiManager.isWifiEnabled());
}
This is the code i am using the disabling part is working fine but the enabling part is not working fine. Soon after enabling the wifi i am printing the wifi state i am getting it as false.
Here is how to turn on and turn off wifi in android.
First you need to declare the following in your manifest file
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.UPDATE_DEVICE_STATS"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>
After doing it that on your Activity class
private WifiManager wifiManager;
#Override
public void onCreate(Bundle icicle) {
....................
wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
if(wifiManager.isWifiEnabled()){
wifiManager.setWifiEnabled(false);
}else{
wifiManager.setWifiEnabled(true);
}
}
Explanation
Get the Wifi service from our system
wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
Check the our wifi is currently turned on or turned off
if(wifiManager.isWifiEnabled()){
Turn on/off our wifi
wifiManager.setWifiEnabled();

Deprecated: Starting with Build.VERSION_CODES#Q, applications are not
allowed to enable/disable Wi-Fi. Compatibility Note: For applications
targeting android.os.Build.VERSION_CODES#Q or above, this API will
always fail and return false. If apps are targeting an older SDK
(android.os.Build.VERSION_CODES#P or below), they can continue to use
this API.

So this will only work for devices with android Pie and below.
