Unstoppable wallet is purposely built as a decentralized management tool for cryptocurrencies.

WALLET FEATURES: - Non-Custodial Multi-wallet >> Manage any number of cryptocurrencies across multiple portfolio-style wallets in a non-custodial manner.

One of the very few wallets capable of supporting fully shielded Zcash transactions as well as the ability to privatize Bitcoin transactions. - Decentralized Wallet >> Designed to work with most major blockchains in a decentralized manner where an app doesn't depend on some server of a wallet provider to send/receive transactions but interacts with blockchain networks directly. - Privacy Focused >> Designed to allow for privacy even in the most privacy-breaching scenarios.

The app is partially TOR enabled and VPN support coming soon. - Fully Open Source >> The most transparent wallet application built to date.

UsbGps4Droid
APK
UsbGps4Droid is a USB GPS provider for the Android operating system, providing GPS support for devices running Android 4.0 and above. The application provides location updates to Android which allows devices without an internal GPS to still use applications which require GPS (such as OSMAnd, Google Maps and log tracking software). I use this USB GPS with my Android Tablet Headunit, because the internal GPS does not work reliably. I have a main controller which automatically starts this application's background service when my car starts. The application is designed to work with any SiRF USB GPS device, however it has been tested as working with GlobalSat BU-353-S4 and a device based on the UBLOX LEA-M8P chip.

UsbNmea
APK
UsbNmea is an Android application that aims to offer some support to USB GNSS antennas on Android.Currently, it only saves the messages that it gets from the antenna to a file on your phone. I have made another app to convert that file to a GPX (as long as the output from the antenna follows the NMEA standard), but I recommend using GpsBabel on your laptop instead.UsbNmea starts a service that should stay on in the background, which gets the data from the USB antenna and saves it into a file. To get the data from the USB antenna, I use the UsbSerial library from Felipe Herranz. Since his code is licensed under the MIT license, I decided to do the same for my code. If you like that, you can support him through the options he lists in the README of the UsbSerial library.
