Eclipse :: coding for Android back again

walking android

After a long while, I’ve recently started to code a few things for Android, launched Eclipse and was greeted with mysterious errors. Which include:

  • “layoutlib is too recent. update your tool” in the Eclipse layout editor. This was solved by upgrading android libs and SDK and also upgrading ADT from inside of Eclipse->Help->Upgrade. The former upgrade probably was not really necessary, but I did it anyway just in case to prevent other incompatibilities from coming out.
  • another gem appeared when I tried to create an empty project to test a few ideas: “error generating final archive: Debug certificate expired”. This required deleting ~/.android/debug.keystore and “cleaning” the project, which eventually led to regeneration of required debug keys. Google says debug keys are expired after 365 days, so it must have been more than 1 year since I’ve started playing with Android.
  • if you plan to access internet from the emulator, open Run->Configuration->Target and set “Additional Emulator Command Line Options” to “-dns-server 8.8.8.8,8.8.4.4″ and don’t forget to require INTERNET permission in the manifest.

And yes, I’ve got two walking plastic Androids to race them against each other around my table.
