Packaged version of UIAutomatorViewer is broken

[Romain Vimont]

On a fresh Ubuntu 14.04.2 LTS, android-uiautomatorviewer just does not work.

Install android-uiautomatorviewer and execute uiautomatorviewer:

The problem is that the wrapper script pass /usr/share/java as parameter for -Djava.ext.dirs, while uiautomatorviewer also depends on eclipse-rcp jars installed in /usr/lib/eclipse/plugins.

The patch attached fixes the problem.

EDIT: but a better fix is https://bugs.launchpad.net/ubuntu/+source/androidsdk-tools/+bug/1438629/comments/3

In fact, androidsdk-uiautomatorviewer works fine in Debian Sid, without modifying the script.

Instead, the package adds symlinks into /usr/share/java:
$ dpkg-deb -c eclipse-rcp_3.8.1-7_amd64.deb | grep ^l

These two symlinks seem sufficient to fix uiautomatorviewer:
sudo ln -s ../../lib/eclipse/plugins/org.eclipse.jface_3.8.0.dist.jar /usr/share/java
sudo ln -s ../../lib/eclipse/plugins/org.eclipse.core.commands_3.6.1.dist.jar /usr/share/java

Therefore, please ignore the patch but add the symlinks instead ;-)
