Android turn On/Off Mobile HotSpot programmatically

Question

I've seen many people ask the question already. But unfortunately, my knowledge of programming is limited only to writing PowerShell scripts :) and I cannot figure out the code.

Perhaps someone will throw java and xml code, applications. Which can turn off or turn on mobile hotspot programmatically, without going into the settings.

I was able to achieve that the settings would open where the user can toggle the state of the hotspot. But I need what the user could not do, tk. the application works in kiosk mode and it only needs to access the API and switch the state of the hotspot.

Answer 1

You can use AndroidWifiManager library to enable hotspot programmatically.

Here is how it can be used in your code (This is already available in the Git ReadMe, I am just rewriting it.)

Step 1 : Add the jcenter repository to your build file

allprojects {
    repositories {
        ...
        jcenter()
    }
}

Step 2 : Add the dependency

dependencies {
    implementation 'com.vkpapps.wifimanager:APManager:1.0.0'
}

Step 3 : Use in your app

Handle error manually

APManager apManager = APManager.getApManager(this);
apManager.turnOnHotspot(this, new APManager.OnSuccessListener() {

    @Override
    public void onSuccess(String ssid, String password) {
        //write your logic
    }

}, new APManager.OnFailureListener() {

    @Override
    public void onFailure(int failureCode, @Nullable Exception e) {
        //handle error like give access to location permission,write system setting permission,
        //disconnect wifi,turn off already created hotspot,enable GPS provider
        
        //or use DefaultFailureListener class to handle automatically
    }

});
//use this line to turn off Hotspot
//apManager.disableWifiAp();

Handle error automatically with inbuilt class

APManager apManager = APManager.getApManager(this);
apManager.turnOnHotspot(this,
        new APManager.OnSuccessListener() {

            @Override
            public void onSuccess(@NonNull String ssid, @NonNull String password) {
                //write your logic
            }

        },
        new DefaultFailureListener(this)
);

//use this line to turn off Hotspot
//apManager.disableWifiAp();
