[Android] RuntimeException: Unable to start activity Need BLUETOOTH permission

If you are working on an Android Java/Kotlin code and trying to use the Bluetooth device of the phone and while running the app you get a Runtime Exception saying "Unable to start activity Need BLUETOOTH permission", well then you have missed adding the user permission to provide access to Bluetooth, add the below line in the AndroidManifest.xml file under the manifest node,

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