Android App FAQ
ZecQT Android is currently in beta, and to participate in the beta program, you need to run zec-qt-wallet and install the APK on your Android phone. Head to the Releases page to download. Run the custom version of zec-qt-wallet
In order to let your Android phone connect to your desktop, you need to run a special version of zec-qt-wallet. You can download it from the releases page and run the binary for your platform. Note that the regular version of zec-qt-wallet doesn't let you connect your Android phone.
You can run your standard version of zcashd or let zec-qt-wallet run its embedded zcashd. Although everything will work fine on Mainnet, since this is beta software, I recommend you run it on the zcash testnet. Add testnet=1 into your zcash.conf to enable the testnet
After your node is synced, go to Apps -> Connect Mobile App to view the connection QR Code
You'll need to allow Install from untrusted sources on your Android phone to install this APK. This is so that you can install the beta APK directly on your phone. (When this is publicly released, you'll be able to get it from the Google Play Store)
When your phone and your desktop are on the same network (for eg., on your home network), your phone can directly reach your desktop over your local network (if there are no firewalls blocking the connection). In this scenario, your phone directly communicates with your desktop zec-qt-wallet. This is the default
If your phone is on a different network (If you're connected via 4G/LTE, for example) or if your desktop zec-qt-wallet is behind a firewall, your phone can't directly reach your desktop. In this scenario, your phone and desktop both connect to a service run by zec-qt-wallet (called wormhole.zecqtwallet.com), which routes information between your phone and your desktop
This is already the default. If you want to connect over the internet via wormhole.zecqtwallet.com, you will need to opt-in by checking the "Connect over internet" checkbox on the connection page
You can also disable connecting over the internet via wormhole.zecqtwallet.com in the Android app's settings
All communication is encrypted end-to-end, so the wormhole service can't see the content of your messages. It can see some meta-data like the IP addresses and date/time stamps.
The Android app will first attempt a direct connection each time you open the App. If a direct connection is not possible, it will then attempt to connect via wormhole (if enabled)
You'll need to install a VPN on your home network, so you can VPN into your network from 4G/LTE networks, and then connect directly to your node. I've had great success with Pi VPN
After you download and install the APK, launch the program and scan the QR Code from your desktop to connect the two. Currently known limitations
- Old-style Sprout addresses are not supported
- You can't select which address to send from. zec-qt-wallet will try to send Transactions from a Sapling address, given you have enough balance
- You can't generate new z-addrs or t-addrs from the phone.
