Created attachment 7207 [details]
repro component sample
This is a regression from 4.12.5, the attached sample no longer builds against 4.14 / b5c14449.
Diagnostic build output:
Steps to reproduce:
1. Download and unzip the attachment
2. xbuild /t:SignAndroidPackage legacybar-2.0/samples/LegacyBar/LegacyBar.Sample/LegacyBar.Sample.csproj
XA 4.14-series / b5c14449
Disregard the link to the sample in comment 0, please download from the attachments section.
The problem caused by Bug #19748, which requests that we use `aapt --max-res-version N`, N being the API level corresponding to $(TargetFrameworkVersion), which in this case is 8:
> Tool /Users/petercollins/Library/Developer/Xamarin/android-sdk-mac_x86/build-tools/20.0.0/aapt execution started with arguments:
> --max-res-version 8
This also explains the aapt warnings:
> max res 8, skipping menu-v11
> max res 8, skipping values-v11
> max res 8, skipping values-v14
...and the errors:
> obj/Debug/android/AndroidManifest.xml:5: error: Error: No resource found that matches the given name (at 'theme' with value '@style/MyTheme').
The MyTheme theme is only defined for API-11 and API-14:
$ grep -rl MyTheme Resources/
The question is thus, what should we do, as this is a regression from 4.12.
1. We could document the change and keep the new behavior.
2. We could revert the change.
3. We could make it "opt-in", and only specify --max-res-version if $(AndroidAaptUseMaxVersion) is True.
4. We could fix the sample, by changing $(TargetFrameworkVersion) to be >= API-11, though this introduces different errors:
> FragmentTabActivity.cs(100,34): error CS0104: `Fragment' is an ambiguous reference between `Android.App.Fragment' and `Android.Support.V4.App.Fragment'
Safest is probably (3), though that means yet another "knob" to control behavior and complicate our tests, so I don't particularly like that idea...
After some deliberation, I think we'll want to go with solution #3 here.
Fixed in monodroid/71ad690f.
Fixed in monodroid-4.14-series/3b3333bd.
The problem is that I misunderstood the context of the problem.
The problem isn't that `aapt --max-res-version N` is being used; this
is required in order to fix other bugs.
The problem is that the wrong N was being used! It needs to be the N
that corresponds to the android.jar that is used when invoking javac,
which starts with $(TargetFrameworkVersion) but can be OVERRIDDEN in
The REAL problem is that the AndroidManifest.xml override wasn't being
used to determine the target SDK version, only
Fixed in master/5809e71f and monodroid-4.14-series/c8b833b0 by using AndroidManifest.xml //uses-sdk/@android:targetSdkVersion to control the `aapt --max-res-version N` value.
We have checked this issue. Now attached sample "LegacyBar component" is building and running successfully without any error. Screencast: http://screencast.com/t/7yqZ5X7t
