I updated to the newest Android ADT and now every project in my workspace says error though there isn't any in the actual files. Even a clean Android project says error even though I have double checked all the preferences and I haven't found any fixes though I have investigated every possible help forum many times.
I have gotten many random error messages and here are just a few: "Current file is not a match for the given config.", "Conversion to Dalvik format failed with error 1" (not anymore), "Invalid preference page path: XML Syntax", "Failed to load properties file for project *" etc.
All my projects worked before updating.
None of the following works: Cleaning the project, deleting the project and importing again, deleting libraries and temporary files and fixing project properties, unchecking the Is Library, updating the ProGruad, updating the Eclipse, moving Eclipse to C:\Eclipse, changing API levels and supported Android versions and so on...
I have fought with this problem for some time now.
EDIT: The following things don't work either: Removing LibraryName_src files (my project has none).
EDIT: I unchecked a checkbox in the general preferences which made Eclipse to delay the packing (I'll check the name of that checkbox later) and the current errors went away but now it says that "Could not find *.apk!"
