I am trying to develop an app for connecting devices using Bluetooth , I am using Plugin.BLE for that purpose, but it is showing some unhandled exception

I am encountering the following exception

Java.Lang.SecurityException: 'Need android.permission.BLUETOOTH_CONNECT permission for android.content.AttributionSource@c82fb2a4: GattService getDevicesMatchingConnectionStates'

I have added the particular dependency as well still I am getting this exception.

Help appreciated!

Java.Lang.SecurityException: 'Need android.permission.BLUETOOTH_CONNECT permission for android.content.AttributionSource@c82fb2a4: GattService getDevicesMatchingConnectionStates'

Since Android 6.0 not every permission is granted just because its placed in manifest. We need to handle runtime permission at runtime. For how to request runtime permissions, you can check: Request runtime permissions.

And from document Bluetooth LE plugin for Xamarin & MAUI,we could find that:

Android 12 and above may require one or more of the following additional runtime permissions depending on which features of the library you are using (see the android Bluetooth permissions documentation)

<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:name="android.permission.BLUETOOTH_ADVERTISE" />

Note:

On Maui, you can use Permissions to check and request runtime permission.
