Building

The build script for this project uses Cake. To run the build, you can use one of the bootstrapper files either for Mac or Windows (experimental support only):

Mac:

sh build.sh --target libs

Windows (experimental support only):

NOTE: Windows build support is still experimental. You may need to first build the externals target, then open the GooglePlayServices.sln in Visual Studio, rebuild it, build the clean target, and then continue on normally building whichever targets you like. This will ensure the appropriate files are downloaded and cached in your user's AppData folder.

powershell .\build.ps1 -Target libs

The bootstrapper script will automatically download Cake.exe and all the required tools and files into the ./tools/ folder.

The following targets can be specified:

• libs builds the class library bindings (depends on externals)
• externals downloads the external dependencies
• samples builds all of the samples (depends on libs)
• nuget builds the nuget packages (depends on libs)
• component builds the xamarin components (depends on samples and nuget)
• clean cleans up everything

NOTE: The externals build task may take awhile to run as it downloads several large dependencies.

You may want to consider passing --verbosity diagnostic (or -Verbosity diagnostic on Windows) to the bootstrapper to enable more verbose output, including downloading progress.

Working in Visual Studio / Xamarin Studio

Before the .sln files will compile in Visual Studio or Xamarin Studio, the external dependencies need to be downloaded. This can be done by running the build.sh or build.ps1 with the target externals. After the externals are setup, the .sln files should compile in an IDE.

Versioning

Historically, Component and later NuGet package versions were based on the revision number of the Google Play Services SDK from the SDK Manager, and later based on the Google Play Services Maven Repository (m2repository) version from the SDK Manager. Because of this, the versions of the components and NuGet packages do not match the version strings of Google Play Services releases from Google. Here is a table which shows a translation of versions mapped to Google's version strings:

NuGet / Component Version	Google m2repository Version	Google Play Services Version
25.0	19 (GPS SDK 25)	7.5.0
26.0	21 (GPS SDK 26)	7.8.0
27.0	22 (GPS SDK 27)	8.1.0
29.0	24 (GPS SDK 29)	8.4.0
	25	8.4.0 (no binary changes)
	26	9.0.0
30.0.1.alpha4	27 (GPS SDK 30)	9.0.1
30.0.2-alpha1	28	9.0.2
	29	9.2.0
	30	(never published)
	31	9.2.1
32.4.0-beta2	32	9.4.0
