Installation Error when trying to record and play audio

[nitin.84india]

Hi,

When I'm trying to install my mobile application using following lines I get an error message saying "Certificate Error".

try {
Player p = Manager.createPlayer("capture://audio");
p.realize();

RecordControl rc = (RecordControl)p.getControl("RecordControl");
ByteArrayOutputStream output = new ByteArrayOutputStream();
rc.setRecordStream(output);
rc.startRecord();

p.stop();
rc.stopRecord();
rc.commit();
p.close();

ByteArrayInputStream input= new ByteArrayInputStream(output.toByteArray());
Player p2 = Manager.createPlayer(input, "audio/x-wav");
p2.prefetch();
p2.start();

}catch(Exception ex){}

Is there anything wrong here?

Thanks,
Nitin.

check your JAD file, do you ask for any permissions in the JAD for which the certificate is not present.
On which device are you trying it...?

How are you installing? (OTA, Bluetooth, ...?)

Are you installing just a JAR, or JAD and JAR?

Is the application signed?

I'm installing it by transferring both JAD and JAR files in a folder through data cable, and then opening the JAD file (tried opening JAR file also but same error popped up). The application is not signed.

OK. Make sure there are no other JADs or JARs in your message inbox. Ideally, make sure the inbox is empty.

If it still won't install, please post the JAD and MANIFEST.MF files here.

What is the name of your Midlet suite... is a signed version of same already installed on the device ?
Check the MIDP & CLDC versions of the target device & in the JAD file.

Cut & Paste your JAD file here.
