-Build compiles and encodes the app named by the import path.
-
-The named package must define a main function.
-
-If an AndroidManifest.xml is defined in the package directory, it is
-added to the APK file. Otherwise, a default manifest is generated.
-
-If the package directory contains an assets subdirectory, its contents
-are copied into the APK file.
-
-The -o flag specifies the output file name. If not specified, the
-output file name depends on the package built. The output file must end
-in '.apk'.
-
-The -v flag provides verbose output, including the list of packages built.
-
-These build flags are shared by the build, install, and test commands.
-For documentation, see 'go help build':
