Install compiles and installs the app named by the import path on the
attached mobile device.

Only -target android is supported. The 'adb' tool must be on the PATH.

The build flags -a, -i, -n, -x, -gcflags, -ldflags, -tags, -trimpath, and -work are
shared with the build command.
For documentation, see 'go help build'.
