Answer 1

you can pass a data uri, mime type and even "extras" to the am command.

am [start|instrument]

am start [-a ] [-d ]
[-t ] [-c [-c ] ...]
[-e
[-e ...]
[-n ] [-D] []

am instrument [-e ] [-p ] [-w]

You could pass them as "extras" and then get the extras that are passed to it.

You would pass them like this:

am start -a android.intent.action.VIEW -c android.intent.category.DEFAULT 
  -e foo bar -e bert ernie -n my.package.component.blah

then in your code:

Bundle extras = this.getIntent ( ).getExtras ( );

if ( extras != null ) {
  if ( extras.containsKey ( "foo" ) ) {
    Log.d ( "FOO", extras.getString ( "foo" ) );
  } else {
    Log.d ( "FOO", "no foo here" );
  }
  
  if ( extras.containsKey ( "bert" ) ) {
    Log.d ( "BERT", extras.getString ( "bert" ) );
  } else {
    Log.d ( "BERT", "Bert is all alone" );
  }
} else {
  this.setTitle ( "no extras found" );
}
