Your android.jar path looks wrong. On my system, it is C:\Android\android-sdk\platforms\android-21\android.jar. Also make sure that you install at least one platform. Run the SDK manager and select one to install. In my case, it was android 5.0(API 21). You would need to point the path to the API level you wish to compile with, for example, if you installed Android 4.2.2(API 17), you would point the path to C:\Android\android-sdk\platforms\android-17\android.jar.
Also, the Additional Libraries and Shared Modules paths shouldn't be pointing into the SDK folder. You should set up separate folders for that. If you want to keep everything together, you could set up C:\Android\Libraries and C:\Android\SharedModules. On my system, I just set up folders under Users folder, C:Users\username\B4A\Libraries
