java.util.Properties#setProperty() doesn't like it when the value is null which was the case when a package had no license. Made sure it won't happen on other properties than the license as well. Also improved error display when an unexpected Throwable is thrown during install (Stack Call is now display if the Throwable has no message). BUG:2037085
Using the Eclipse projects for ddmuilib. ddmuilib requires SWT to compile. SWT is available in the depot under prebuild/<platform>/swt Because the build path cannot contain relative path that are not inside the project directory, the .classpath file references a user library called ANDROID_SWT. In order to compile the project, make a user library called ANDROID_SWT containing the jar available at prebuild/<platform>/swt.
