Android Packaging Error for Necessitas

  • Hello everyone,

    This is my first time posting here, so if this post seems like it should be in a different section feel free to let me know =).

    I am trying to run a simple application for Android using Necessitas. The application does not have any functionality; all it does is display (or is supposed to display) a button on the screen. I am just doing this as a test to get a feel for Necessitas before I start any serious development. When I hit the 'run' button Necessitas begins to build my application, but then stops and displays the following error message:

    Packaging Error: Command 'C:\Users\Catalyst\necessitas/apache-ant-1.8.2/bin/ant.bat clean debug' failed.Exit code: 1
    Error while building project atest2 (target: Android)
    When executing build step 'Packaging for Android'

    A search on Google did not produce any instructions to help remedy my issue. Please help me! I have a lot of great ideas for apps that I would like to start developing ASAP!


  • Hi,

    I am also getting this error, how to resolve this?

    If anybody knows, please guide...


  • After searching in the google I found that tools.jar should be present. And I have this file in the path: C:\Program Files\Java\jdk1.6.0_18\lib

    But still it is not installing in Android HTC Hero device. What's the problem?

  • Hi,

    I had the same issue after having changed some of the project setting without doing care.
    Finally I found the answer on Leonard's blog:

  • I am having exactly the same issue but changing the Android target SDK to the latest version has not fixed it. Any further thoughts?

    copy toos.jar from ..\java\jdk1.7.0_0\lib to ..\java\jre7
