![]() ![]() ![]() ![]() Private String LOG_TAG // Just for logging purposes. Then in our activity, which in my case will be the MainActivity.java, we need to create a few variables: The first thing you need to do is get the permissions in the Manifest.xml file to access Bluetooth: This is super easy, so let’s get started. So, the plan is to have a button in the app that says something like “Enable Bluetooth” and prompts the user for permission to enable Bluetooth:Īfter selecting the “Enable BT” in the app, the user gets prompt for permission to turn on Bluetooth. So instead of making X number of screenshots for “Getting started” guides depending on the OS level and the skin of the device, this approach is mainly universal (sure, the dialog might look slightly different on a different OS level) While a user can turn Bluetooth on from multiple places or ways in an Android device, one of the issue I had on a client’s project was the need for a unified way to show the user how to turn on Bluetooth in their android device. I might make another post for those specific subjects.Īlso, this tutorial is based on regular Bluetooth and not Bluetooth Low Energy (LE) Turn on Bluetooth Note: This tutorial DOES NOT explain how to pair, connect and send data to/from another Bluetooth device. The source code for this Android Studio project is linked at the bottom. I’ll review how you can prompt the user to enable/turn on bluetooth in your Android device, how to show already paired bluetooth devices, and how to scan for new nearby bluetooth devices.įor this tutorial, you’ll need a physical Android device (I haven’t found a way to make the emulator proxy the computer’s bluetooth signal), and I guess at least another bluetooth device in range for you to test things. In this post I’m going to outline how to get a list of available nearby bluetooth devices to show when scanned by an Adroid device. 24 November 2015 Comments Off on Scanning for Bluetooth Devices in Android General Software Development ![]()
