Using a Ledger with an Android Device

Requirements

In order to use a Ledger Wallet with your Android phone, you need to have a modern phone or tablet that supports USB-OTG (USB On-The-Go) as well as a USB-OTG adapter to go with it. If you don't have an OTG adapter yet, you can pick one up on Amazon for just a few bucks. The adapter will allow you to plug the Ledger Wallet into your device.

If you are not sure whether your device supports USB-OTG, the easiest way to check it is by using an app like USB OTG Checker.

Setting up Your Device

Before you connect your Ledger Wallet to your device, you first have to install an application made by Ledger, which can be found here. Simply open the URL on your device and click on the file android-u2f-bridge-x.x.apk. Once you downloaded the file, open it on your device and you should be asked to install it. Once installed, tap Done, as it is not yet possible to open the app.

Now, connect your Ledger Wallet and open the Ethereum application. Make sure both Contract Data and Browser Support are ON (Note: this is no longer required in newer versions of the Ledger firmware). Open your browser and go to MyCrypto. On the Send & Receive page, select the Ledger option and tap on Connect to Ledger Wallet.

You should see a pop-up asking if you want to allow the Ledger application you just installed to access the Ledger Wallet. Tap on OK and you should be able to see your addresses on MyCrypto.
