Why am I having such a hard time getting into the swing of Android development? I\'ve been developing in various languages over the years and, for some reason, just can\'t s
First of all check if you have done all the described steps as explained on the developers site. Then, for the errors :
Unable to resolve target 'android-16'
Make sure that you have installed API16, this errors occurs if you have mentioned your targetsdk to 16 in your Manifest while the sdk for API16 is not installed. You can either install the API or edit the targetApi of your project to the minimum required version, for the support library you are using I think API 11 is the minimum required android version.
android:Widget.Holo.ActionBar
This error should also be fixed once the targetsdk is fixed in your project. Since to use Holo.ActionBar you'l need to target your project to minimum supported api level ie. 11 or higher.
