Installing Java applications / games that require access to an external source, either the phone memory, flash card, Internet or cell, you encounter a problem when the phone sprashivat permission to access the application to something.
For example if we are downloading a file with unsigned opera mini or ucweb it will ask for permission to read or write simultaneously.
But if it is signed there will be no such prblm.Just like sis app.
here is a simple procedure to sign jar files:
- upload your .jar file to any free file hosting service and copy the direct link of it ( i recoment http://willhostforfood.com/ )
- open this link *(original site is http://simak.ru/ which is in Russian.Provide link is google translated)
click on On-Line certifier & select ur phone model and required permissions
- paste the direct link to the jar file on the field
- click:certify midlet
download the jar and jad files which gets in the next page
- copy both jar and jad to C:\nokia \install directory of ur mobile
copy the exp.cer & halmer.cer to ur phone.Using X-plor open it & save it with all options. (download certificates.zip)
- now open application manager and install ur jar file.
- without closing application manager find the installed file in the list and under suite settings set all as "always allowed"
- now you can use the app without any security asks!!!
