What device(s) are you experiencing the problem on?
   All android smartphones - current test device Samsung GT-P3110

What firmware version are you running on the device?
    Latest firmware for Samsung GT-P3110

What steps will reproduce the problem?
    Install the app and then run it 2 times

What is the expected output? What do you see instead?
    The app runs fine but starts very slowly - always about 8 seconds

What version of the product are you using? On what operating system?
    Latest script-for-android-template on android 4.1.1

Please provide any additional information below.
    I have lots of GC_CONCURRENT entries in my log file followed by these two lines:
1) D/sl4a.ScriptService:185( 9709): No need to update 
/data/data/com.langtech.wikitestswebsite/files/content.zip
2) D/sl4a.ScriptService:163( 9709): Checking if 
/data/data/com.langtech.wikitestswebsite/files/script.py exists

    The first time I run my app these GC_CONCURRENT entries do not appear and are clearly delaying my app starting. It would appear that the integrity of the files is being checked at start up.

I've fixed the problem by modifying the function "needsToBeUpdated(String 
filename, InputStream content)" in the file ScriptService.java". I'm just 
checking if my application is already installed and if it is I'm not doing any 
updating.
