Monerujo

Another Android Monero Wallet

Download the APK for the most current release here and install it
Run the App and select "Generate Wallet" to create a new wallet or recover a wallet
Advanced users can copy over synced wallet files (all files) onto sdcard in directory Monerujo (created first time App is started)
See the FAQ

You may lose all your Moneroj if you use this App. Be cautious when spending on the mainnet.

Based off monero v0.11.0.0 with PR #2289 applied
currently only android32 (runs on 64-bit as well)
works on the testnet & mainnet
sync is slow due to 32-bit architecture
use your own daemon - it's easy
screen stays on until first sync is complete
saves wallet only on first sync and when sending transactions or editing notes
Monerujo means "Monero Wallet" according to https://www.reddit.com/r/Monero/comments/3exy7t/esperanto_corner/

The backups folder is now called "backups" and not ".backups" - which in most file explorers was a hidden folder
Wallets are now created directly in the "monerujo" folder, and not in the ".new" folder as before
You may want to check the old folders with a file browsing app and delete the ".new" and ".backups" folders AFTER moving neccessary wallet files to the new locations. Or simply make new backups from within Monerujo.
Also note, that on some devices the backups will only be visible on a PC over USB after a reboot of the device (it's an Android bug/feature)
Created wallets on a private testnet are unusable because the restore height is set to that of the "real" testnet. After creating a new wallet, make a new one by recovering from the seed. The official monero client shows the same behaviour.

No need to build. Binaries are included:

If you want to build them yourself (recommended) check out the instructions

Then, fire up Android Studio and build the APK.
