It's just a new manifest attribute. Older versions of the OS will
ignore it. Build against the 2.2 SDK, but set your minSdkVersion to an
earlier OS. Be careful not to use anything new on the Java side
without checking first via something like reflection, however.

Those errors can arise due to not using a Google APIs build target.
You can check your build target by right clicking on the project in
Eclipse, selecting Properties, then selecting Android.

installing some platforms fixed it in my case.

Casting to an integer removes the fractional portion. Casting has a
higher operator precedence than multiplication or addition, so happens
first in your full expression. Parentheses could be used to alter when

You can use the LogCat view in Eclipse to see more details when your
application crashes. In this case it is probably due to the fact that
the getLastKnownLocation method can return null. That would cause a
NullPointerException when you try to call a method on the null like
getLatitude.

That actually has to be removed for your purposes. The android.R class
is for built-in stuff, like android.R.drawable.ic_menu_edit. The R
