check capabilities dinamically

[felixksp]

Is it possible to check capabilities of the application dinamically? For instance to know if the application is allowed to send and receive data or to read user data. I am referring from code, to be able to display customized error messages depending on not allowed capabilities.

Thank you.

From MIDP 2 Javadocs

MIDlet.checkPermission

public final int checkPermission(String permission)Get the status of the specified permission. If no API on the device defines the specific permission requested then it must be reported as denied. If the status of the permission is not known because it might require a user interaction then it should be reported as unknown.

Parameters:
permission - to check if denied, allowed, or unknown.
Returns:
0 if the permission is denied; 1 if the permission is allowed; -1 if the status is unknown
Since:
MIDP 2.0

You pass it the same permission strings what you need to define in the JAD file (so your string is correct)

Are you running the app on an operator branded phone? Which phone model?

hi dear,
i have tested it with signed and unsigned application in nokia 6630,6680,n80 phones.

see what i have done is as below, please correct me if i have taken any wrong step.

1- int j= this.checkPermission("javax.microedition.io.Connector.file.read);
and then i am checking value of j which this api call returns.

so can you tell me what should it return in both case 1- when i have not given permission in suite setting and 2- when i have set permission always allow in suite setting.

Thanks,
Nekin

First 0 (not allowed), then 1 (allowed). Remember to request the proper permissions in your JAD file!

ya that's fine dear

but have you checked with above permissin in you midlet
since i am checking for this permission "javax.microedition.io.Connector.file.read" and i am getting -1 instead according to your reply it should give me 0 or 1.

so can you please check this practically if you have not checked ?

so that i can get exact solution to it.

Thanks,
Nekin
