The Benefits of Positive Feedback

Have you ever downloaded an app from the Android Market, or App Store, and after using it for a few minutes thought “this is just awesome”? If you’re like me, the answer is yes. But was your first thought to contact the developer and tell him how happy you are? Or did you just keep using the app, happy to have something that works?

I was reading the comments on Tap That! Number the other day. Here’s the latest review by someone called Jake:

Android Income Report #4

At long last, here is my income report for the month of July. This is a very different story to previous reports, mainly thanks to my Google+ Invites app which made a few hundred dollars in one day. I also released a major update for Tap That! Number, and published a new app (CPU Usage Live Wallpaper) with both free and paid versions. It was a pretty hectic month! Read on for more details, and an overview of the month’s earnings.

Intent.ACTION_SEND Crashes Facebook App

I came across a rather obscure bug today, while trying to submit my app Tap That! Number to the Amazon Appstore. I received a rejection notice detailing several problems with my app, including this strange one:

Application’s “Feedback” functionality “Facebook” option is not working.

At first I had no idea what this meant. My app never mentions Facebook at all. The only “Feedback” option I have is a menu item designed to send an email to the developer.

After digging around a bit, I found that the code I was using to launch an email intent was also recognising Facebook and presenting it in the list of available apps. Here’s the code I was using:

Google+ Now Open To All, With a Ton of New Features

I woke up this morning to a perfect storm of Google+ announcements. Firstly, the big news – Google+ is now available to anyone with a Google account. No invite required. This is great news, as it lowers the barrier to entry significantly. I can now invite all my friends to join, and they can invite … Read more…

How to make $250 a day (and get banned from the Android Market)

Logo for the Google+ Invites App

A few weeks ago I did something which, in retrospect, was probably rather stupid. But it was surprisingly successful while it lasted. As I wrote earlier, I’ve been using Google+ since the day after it was launched. I myself received an invite from a stranger who was offering invites publicly. For this reason, I’ve been keen to share invites with anyone else who’s looking for one. I put up a post on this blog offering free invites, and got a huge response from the Android community. In fact, there were so many responses that it overwhelmed my email after a few days. There’s no way I could have kept up with the demand.

Rather than stop accepting requests altogether, I wanted to make it easier to handle the load. (NB: At this stage there was no limit to the number of Google+ invites you could send.) My first thought, trying to work out a faster way to do things, was “hey, is there an Android app for this?” A quick search turned up a negative. No Android apps offering Google+ invites. So, why not make one? It seemed a pretty good idea, so I spent that afternoon writing a simple app that accepted an email address, and a description of the request. The data was sent to a PHP script on my server, so I could go through and invite the email addresses stored in a database.

Actually, it’s not that simple to write an Android app that POSTs data asynchronously to a server, checks the response, and handles errors gracefully. I re-used some classes from another unreleased project, but it was still a bigger job than I expected. But the actual coding is an issue for another day. The most interesting part came when I released the app on the Android Market.
