I downloaded the most recent ADT to start learning how to do some Android Development (I have tried it before but didn't go far with it). Delphi open remotedekstop in form.

For the first one, make sure that project.properties file is present inside your project folder. You should be able to create one by right clicking your project and clicking properties, and in the popup window click the Android tab and choose your desired build target.But you might not be able to do that if Eclipse cannot any sdk tools.platform-tools folder should be inside sdk folder in ADT Bundle, not inside eclipse folder.

In Eclipse, on your toolbar, click Window and then preferences. In the popup window, click on Android tab and you'll see a textbox saying SDK location. Click browse and find your SDK folder. Again, if you downloaded ADT bundle, it should be inside this folder.

Getting NullPointerException when trying to start avd. I just downloaded the ADT bundle for Mac and ran android avd. Anyone know why it would fail?

The following worked for me:From the command line I navigated to the tools folder of the Android-SDK folder. From there I ran this command: android list avdThis produced a list of all of my virtual devices but one of them showed itself to be the problem. The exact output was as follows: The following Android Virtual Devices could not be loaded:Name: Tab31Path: /Users/User/.android/avd/Tab31.avdError: Failed to parse properties from /Users/User/.android/avd/Tab31.avd/config.iniereIf you see this then make note of the 'Name' property ('Tab31' in my situation) and run the following command (obviously replacing the name of my AVD with yours): android delete avd -n Tab31After that I was able to start the AVD Manager without any problem.
