I just went to build an app, but my Build Tools is out of date (26.0.3), and I received a very helpful message to that effect. So I went to Tools > Settings as suggested, to the Android SDK tab, but when I click on Install Packages, the .bat that runs just ends with this message at the end of each section (after parsing various package.xml files):
Warning: File C:\Users\jeff_\.android\repositories.cfg could not be loaded.
In fact, that file doesn’t exist on my machine, and I don’t even remember reference to that folder in the past. My JDK is a little out of date (C:\Program Files\Java\jdk1.8.0_152), but that doesn’t seem like it should give this error.
I could try installing the SDK and JDK from scratch, but it seems like SAB should be able to perform the update. Any suggestions?
I don’t think the <repositories.cfg> file was the issue at all. When I tried creating it, it didn’t give me the warning, but it also didn’t help to get my SDK packages up-to-date either.
In the end, I downloaded and re-installed the entire SDK from scratch, which with the dicey Internet in Chad took a fair amount of time and frustration. I downloaded the sdk-tools (152Mb) and created the c:\sdk folder, then ran Install Packages from within SAB to get the additional packages (several hundred more Mb). Those downloads failed several times, but I just kept running the Install until it succeeded. And now I can built apps again.
My old C:\sdk folder was 656Mb. My newly installed c:\sdk folder is 414Mb. It is smaller because it doesn’t have some of the older folder versions, like it only has the 27.0.3 folder in build-tools, and not the older 25.0.3 and 26.0.3.
So I don’t know why SAB couldn’t update the SDK packages. It is nice in some ways to have a “fresh” SDK folder, without the unnecessary old stuff, especially since I do sometimes help people install app builders by copying my SDK folder. But it was also a fairly painful process. So what happened? I don’t think I had built an app in a few months - did it get too far out-of-sync, and couldn’t bring the SDK packages up-to-date?
