Description
I’ve created a new repo for Preview3 based on my net10-android36.1 production repo and have built for both net11.0-android36.1 and net11.0-android37 (against the Android17 QPR1 Beta1 CP31.260403.005.A1 on a Pixel6). The only difference between the builds is <EnablePreviewFeatures>true</EnablePreviewFeatures> for android37 and
< EnablePreviewFeatures> false </EnablePreviewFeatures> for android36.1.
The Net11 builds contain the latest NuGet packages as compared to the NET10 production build. However, I can’t upgrade them further due to dotnet/android-libraries#1401. So, I’m guessing they are at least a couple of weeks old.
The apk sizes are -
net10.0-android36.1 21,727 kb
net11.0-android36.1 33,841 kb
net11.0-android37 33,845 kb
So, an approximate difference of 12kb. Can you explain/suggest how I can reduce both Net11 APK sizes?
The only difference between the net10-android36.1 production build and both the Net11 builds is that the NuGet’s in the production build can’t handle any further NuGet updates because of issue #10700, which certainly looks to be fixed with Net11. Could you please supply a timeline for when that fix will be backported to Net10?
The other thing that is strange is the build output for the Net11 preview; it is only 10 lines long, even though it is set to Diagnostics. All it really contains are a couple of warnings, CA1416 and IL6001, which I will need to address.
