Android software engineer Jean-Baptiste Queru recently wrote on the Google mailing list, "Where the situation is really tricky is that the system partition on the U.S. G1 was already filled to the brim with cupcake, and we were routinely flirting with build sizes that were a few dozen KB under the limit (or several MB over...)."
Meanwhile, I was alarmed when I read that the Android 1.5 "Cupcake" update had taken up most of the available space where the operating system resides. To see exactly how much free space was left, I used the Linux command "df" to display the G1's internal partitions.
As you can see, the system partition is 99.5 percent full, which led me to wonder how future updates likeand would be able to fit on a G1 when Cupcake used all the available space.
When I contacted
Though that's good to hear, it doesn't change the fact that the G1 has limited storage. The day will come when Android outgrows the G1's available 70MB and I was worried that the handset might only receive security updates instead of significant upgrades. Recent events, however, might have changed my mind.
I'm starting to believe that Google will differentiate between first and second-generation hardware when rolling out updates. If that ends up happening, then future specific updates would be destined for the G1. Donut could become Android 1.6--I've spotted Android builds appear in mobile analytics reports that identify Donut as version 1.6--and appear on G1s later this year.
I recently spoke with Steve Kondik (aka Cyanogen) who has released his own customized builds of Android. He told me that Donut builds were a few megabytes larger when compared with Cupcake, but new compression methods were able to shrink the total install up to 10 percent. "I don't think that Donut is going to have any problems fitting on the G," he said "To make it smaller, I use a tool called optipng which analyzes PNG images and finds the optimal compression for them. Apps can be significantly reduced in size by using this tool and applying better compression to the package itself."
This does not mean that Donut is guaranteed to appear in its full form on the G1, but it gives new hope. If Google implements similar compression technology, they might be able to cram all the new features in the same space they fit Cupcake. Steve went on to say, "I don't know what features are going to be coming up in future releases like Eclair, but even if they exceed the space limit then, us hackers will still get it out to everyone one way or another."
Android engineer Dan Morrill also weighed in on the discussion. He says that rumors about the G1 are exaggerated. Many customers were upset when they first heard about the G1's limitations, but it looks like some creative coding will extend its life.
So while the G1 might get Donut, it remains to be seen what future updates customers can expect. The limited storage will eventually catch up and G1 owners need to understand this. T-Mobile will continue to roll out updates, but will they match the official builds we see on second-generation Android phones?
