Conversion to Dalvik format failed with error 1

UNEXPECTED TOP-LEVEL EXCEPTION:

java.lang.IllegalArgumentException: already added: Lcom/androidquery/AbstractAQuery;

[2012-08-09 22:41:36 - Yachts and Tall Ships] Dx 1 error; aborting

[2012-08-09 22:41:36 - Yachts and Tall Ships] Conversion to Dalvik format failed with error 1

Solution:

Once again, I looked thru all sub projects (library projects) and noticed that I have android-query-0.22.10.jar included twice in two library project libs folders.

I moved the jar to what we call lib_common/libs and referenced that jar from there everywhere I needed.

Do not include the same class name in different library projects, use a single common project were you keep your commonly used jars.

Format JSON in free TextWrangler

Here is an easy way to get formatted JSON in FREE TextWrangler:

Create text (Python) file:
~/Library/Application\ Support/TextWrangler/Text\ Filters/Format\ JSON.py




#!/usr/local/bin/python
import fileinput
import json
if __name__ == "__main__":
  text = ''
  for line in fileinput.input():
    text = text + ' ' + line.strip()    
  jsonObj = json.loads(text)  
  print json.dumps(jsonObj, sort_keys=True, indent=2) 



or shorter:


#!/usr/local/bin/python
import fileinput
import json
print json.dumps( json.loads(''.join([line.strip() for line in fileinput.input()])), sort_keys=True, indent=2)
