Is it possible to run the JumpNote demo application for Android Cloud to Device Messaging http://code.google.com/p/jumpnote/ on an unrooted Google Nexus1 phone? Did anyone install and run JumpNote on an unrooted Nexus1? (JumpNote works with Android 2.0+, it needs Android 2.2 for push-sync, but it can run and be sync-ed manually in Android 2.1)

+1  A: 

It's possible to run the demo app on pre-2.2 devices (but not pre-2.0 devices). To do so:

  1. Enable non-Market install of apps by enabling 'Unknown Sources' in Settings > Applications on your device.
  2. Download the latest .apk file in the downloads section of the project from your device's web browser.
  3. Once the download is complete, tap on the downloaded file (in the Downloads list in the phone's web browser) to install the app.

Note that you won't see the automatic synchronization until your Nexus One is updated to Android 2.2. Also note that JumpNote is just a demo, and shouldn't be used to store any important or sensitive data.

Hi Roman, thank you, thank you :) I got the Android 2.2 OTA update and the JumpNote demo app is great and fast.
