问题
I would like to start my own SMS editor when user selects "Send message" from contacts application. How do I define intent in manifest file to allow passing contact details to the editor?
Thanks a lot

There are many "contacts applications" for Android, not just one. You declined to indicate which "contacts application" you are referring to.
Some "contacts applications" may use ACTION_SENDTO with an smsto: Uri for sending an SMS. In that case, you can add an <intent-filter> to your manifest watching for an android.intent.action.SENDTO <action> and a <data> with scheme of smsto:. That should trigger your activity to be an option for the user.
However, bear in mind that not all "contacts applications" may use this.
