By default, the only ABI set in release mode is armeabi-v7a
While this may be appropriate for devices (perhaps arm64 should be included also) this causes a deployment failure when deploying to the x86 emulator
I suggest that we either include the appropriate ABIs for emulator testing, or provide a more appropriate error message when the incorrect ABI is set for the chosen deployment target

This is now fixed in the property pages. All the ABIs are selected by default (and there are other options, like fastdev or not and such).
My bad. I checked debug. It makes sense that release will only be arm, though, but I'm reopening while we decide.

We're trying to "thread" between two subjective requirements:
1. We don't want the default app size to be "too big", and
2. We want the default Release app to be "useful"
Each ABI requires 1.3-2MB in native libraries be added to the .apk, depending on whether `libmono-btls-shared.so` is required (required to support TLS 1.2 with WebRequest), so we want to choose only *one* ABI *by default*.
Additionally, we want the default Release .apk to be able to be meaningfully useful on the Google Play Store.
x86 would not be "meaningfully useful"; very few Android devices support x86.
The last time we updated the default, armeabi-v7a was the ABI that best fit these requirements: it is supported on a majority of Android devices, so making it the default single ABI made the most sense.
x86 doesn't make sense, and *still* doesn't make sense. If we were to update today, *arguably* arm64-v8a should be made the default, but I see no reason for x86 to be made the default.
If you need x86 support, enable x86 support in the Project Properties dialog.

This is something we should do.
