What APK app paid in full can I use to make an Android phone connect to Wi-Fi in the app and not on the Wi-Fi settings phone

To create a mobile application for connecting to Wi-Fi networks directly from within the app, you would typically use the Android API for managing Wi-Fi connections. However, accessing Wi-Fi settings directly from an app requires specific permissions, and many features can only be implemented with the user's explicit consent.

### Recommended App Types:
1. **Wi-Fi Manager Apps**: You can look for paid apps in the Google Play Store that are designed as Wi-Fi managers. These apps often provide a user-friendly interface to connect to, disconnect from, and manage Wi-Fi connections within the app itself.

2. **Custom ROMs/Rooted Apps**: If you have a rooted device or are using a custom ROM, there may be apps available that allow you to manage Wi-Fi connections more freely from within the app.

### Important Permissions:
If you are developing your own app or looking for an app that connects to Wi-Fi directly, ensure that it requests the necessary permissions:
- `ACCESS_WIFI_STATE`
- `CHANGE_WIFI_STATE`
- `ACCESS_FINE_LOCATION` (for scanning available networks)

### Example Development Approach:
If you intend to create an app yourself, here's an outline of how you can achieve Wi-Fi connectivity programmatically:

1. **Check and Request Permissions**: Ensure the app has the required permissions.
2. **Enable Wi-Fi**: Use the `WifiManager` class to enable or disable Wi-Fi.
3. **Connect to Wi-Fi**: You can create a `WifiConfiguration` object to set up the network parameters and use the `WifiManager` to connect to it.

### Sample Code Snippet:
```java
WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true);

WifiConfiguration wifiConfig = new WifiConfiguration();
wifiConfig.SSID = String.format("\"%s\"", "yourSSID");
wifiConfig.preSharedKey = String.format("\"%s\"", "yourPassword");

// Add the network configuration to the WifiManager
int netId = wifiManager.addNetwork(wifiConfig);
wifiManager.enableNetwork(netId, true);
```

### Considerations:
- Users must be aware and consent to connecting to networks.
- Be mindful of security and privacy when handling Wi-Fi credentials.
- Google Play may restrict apps that don't follow their policies regarding permissions and user data.

### Conclusion:
While there are existing applications that offer more control over Wi-Fi management within the app itself, your options will be limited to those that are compliant with Android's permissions model. If you are developing an app, ensure that you follow best practices and comply with the necessary guidelines.
