This PR increases Android's `minSdkVersion` to 21. There are two changes in this PR aside from simply increasing the number from 19 to 21 everywhere. First, tests using `flutter_gallery` fail without updating the lockfiles. The changes in the PR are the results of running `dev/tools/bin/generate_gradle_lockfiles.dart` on that app. Second, from [here](https://developer.android.com/build/multidex#mdex-pre-l): > if your minSdkVersion is 21 or higher, multidex is enabled by default and you don't need the multidex library. As a result, the `multidex` option everywhere is obsolete. This PR removes all logic and tests related to that option that I could find. `Google testing` and `customer_tests` pass on this PR, so it seems like this won't be too breaking if it is at all. If needed I'll give this some time to bake in the framework before landing the flutter/engine PRs.

guide to install the flutter tool.
For additional samples, see the
flutter/samples repo.
Available examples include:
-
Hello, world The hello world app is a minimal Flutter app that shows the text "Hello, world!"
-
Flutter gallery The flutter gallery app no longer lives in this repo. Please see the gallery repo.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
-
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.dev/platform-channels/.
-
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.
Notes
Note on Gradle wrapper files in .gitignore:
Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
