ADT - problem converting AIR to APK (file disappears)

I run the following command @windos.commandline to convert an AIR file to an APK for usage on Android:

adt –package -target apk -storetype pkcs12 -keystore cert.p12 myApp.air myApp.xml .

All mandatory files are inside the same folder where I run the command from and I do not get any error at all.

After I enter the password for the certificate I can see that a temp file is created in working directory ("apk6668400655392463515.tmp" name is similar to this one I copied just from this process' last try to convert).

When the converting has ended the temp file is removed but no other files appears - either the file is located somewhere else afte running the adt packaging process or it is simply removed for unknown reason; please let me know where I could check for the problem.

ADT version is 3.0.0.4080

AIR is compiled using Flash CS5

in myApp.xml I have set the version to 2.7:

"<application xmlns="http://ns.adobe.com/air/application/2.7">"
