Several exceptions that often occur after adding a third-party jar package:

Proguard returned with error code 1.See console

Scenario 1:
Proguard returned with error code 1. See console
Error:c:/documents (the system cannot find the specified file)
Later found because the entire project was put on the desktop, and the desktop directory is c:/documents and settings/administrator/desktop, in which there are spaces, and proguard to compile the time is not allowed to have spaces
If the correct path is not good enough, delete Proguard directly.

Note: The SDK and program paths are best not to have whitespace

Scenario 2:

Proguard returned with error code 1. See console
Abnormal:

Java.lang.ArrayIndexOutOfBoundsException

Workaround: Change "-dontpreverify" in Proguard.cfg to "-dontoptimize"

Reference article: http://groups.google.com/group/android-developers/browse_thread/thread/eca3b0f5ce6ad00f

I delete the Proguard folder (which is empty at this time) in the project and then run the project again, OK.

Scenario 3:

[2011-10-21 13:22:32-zmksmarket_build_v1.0] Proguard returned with error code 1. See console

[2011-10-21 13:22:32-zmksmarket_build_v1.0] java.io.IOException:Can ' t read [[email protected]] (No such file or Directo Ry

[2011-10-21 13:22:32-zmksmarket_build_v1.0]
At Proguard. Proguard.main (proguard.java:499)

The reason for throwing such an exception is that the reference path of the third-party jar is incorrect, and the jar package that needs to be ignored is not found.
