NDNFit Android application based on professor Jung's work. Did not fork as we don't have access to the original work on BitBucket.

Jan 20, 2015 - v0.1

What it does:

• Capture time-location data (Use NETWORK_PROVIDER instead of GPS_PROVIDER for GPS for now)
• Use the identity provided by Android Identity Manager to sign the captured data
• "Upload" captured data to the DSU running on remap server memoria.ndn.ucla.edu

How to use:

• Install ndnfit, identity manager, and nfd-android on Android device
  • Ndnfit: download
  • Identity Manager: download
  • Nfd-Android: download
• Open NFD-Android (the link to github repo), and configure it. Need to connect nfd-Android to the NDN testbed (the best choice is remap server memoria.ndn.ucla.edu) and configure route.
  • Step 1: open the app, click "general"
  • Step 2: choose “faces” or “routes”
  • Step 3: click the “+” to add face after choosing "faces"
  • Step 4: click the “+” to add route after choosing "routes"

• Open identity manager, request an NDNFit identity (see the steps)
• Open ndnfit to capture and upload data
  • Choose an identity to use with the help of Identity Manager
  • Click “start tracking” to start to capture data
  • Click “stop tracking” to stop capturing data. The captured data will be uploaded to DSU within ten minutes
  • Click “show result” to show path on google map locally
  • Click “Reset Data” to clear local cache
  • “Encrypt” and “Decrypt” function have not been added yet

Known Issues:

• Nfd-Android stops working after about 20 minutes unless refresh it periodically
• The DSU (which uses Repo-ng ) is not robust enough. The number of data packets it can hold is limited.

Development:

• Open in Android Studio, SDK 21, build tools 21.1.2; sync Gradle
