  5. Hi, Gagan Singh
    Are your application store all data in /data/data/ dir?

    I think it may happens if some of your app data stores in SD card.

  9. Hi,

    is there any way to clear other applications app data or uninstall app silently ….i dont want clear my current app data ,need to clear other app data…

    • Hi sreelal,
      I think this is impossible to make clear data or remove other application without special permissions.
      I know about some special relations between application which signed with same certificate.

  10. very nice forum
    thanks.
