  1. hey Jeffrey,

    My name is Rafael Sanches and I have played with some of your android apps. I see that, like me, you are very interested in the android stuff.

    Would you like to make something together? We could brainstorm someday to find something useful to develop. I have servers and I think that we can build any idea.

    I have developed the app “craigsnotifica” on my free time and lately what happens is that I develop my apps to the half and then i loose interest. I hope to get some productivity boost by collaborating with someone.

    what do you think?

    Great app. I would like to contact you about it and work on making the data more easily available. I assume you did a data scrub of the VTA website to get the route schedules. I want to work at making it easier for developers to get the data they need.

    Hi Jeffrey,

    I really like Quake Alert, but could you add epicenter depth to the app?

    • Jeffrey Blattman says:

      yes that would be easy. i’ll keep it in mind for the next time i get into the code.

    I’m having some trouble with the latest update to Quake Alert. I have been using and enjoying QA for many months, this is the first time I have experienced a problem. The app works only if I have, “use wireless networks” checked in my system preferences. If I only have, “Enable GPS Satellites” checked, the app does not work. I get an error message: “”Unknown Location, Ensure that you have at least one location…”

    Some comments: Google Maps works fine with GPS only. QA used to work fine before the last revision. I’m running Android 1.6 stock on a T-Mo myTouch 3g original.

    Ps. Thanks for making the type bigger in the listings. That really helps me.

    • Jeffrey Blattman says:

      yes. i changed the permissions to only request “coarse” location, and not “fine” location. this was probably the wrong thing to do. i’ll fix it up and get back to you.

    Re: Clear Sky Droid
    A display of the 2 bar graph on a live home screen widget linking to the full clock would be nice. I think a display of 2 graphs per widget height would be really great.
    I had a few problems: It hung on first use, and a few errors popped-up while searching for clocks. I believe the hanging could be the result of two factors: Default setting on “closest” and my GPS radios where turned off at the time. Perhaps a time-out issue on GPS data ? As for the search errors, the messages just flashed so fast, I can’t say what it was.

    When using the shortcut widget, pinch zoom no longer works on my browser. I use Mozilla. After clearing cache, no change. Since Clear Sky Droid’s widget have been the only change, I tried removed them, and pinch-zoom was available again.

    I’ve been enjoying your Next VTA app for awhile and today i was going to recommend it to a friend but I can’t locate it in the Android Market. So what’s up with this?

  8. Drew says:

    Why not open source Next VTA if you don’t want to work on it anymore? Many people depend on the VTA and your app is a public service, so let others maintain it if you can’t.

    I want to bring back your next vta apk.
    would you send me an email, so i can contact you?

    Hi Jeffrey!

    I have used one of bitmap scaling class in my android app. I just want to know that, do I have to obtain some license to use your class, although I have amended it in very different ways but still I was concerned about license. Reply soon…!
