python - Launch android app from SL4A script?

Question

I have the following in /sdcard/sl4a/scripts/twitter.py

import android
droid = android.Android()
droid.launch('com.twitter.android')

And if I run it in the console or the background, it immediately exits with code 1, and the log file is empty.

If there are other ways to launch applications from some sort of script, I'm open to suggestions. I know of Tasker, but I'd rather write text scripts than use a wizard.

Answer 1

you can use startActivity for that:

import android
droid = android.Android()
droid.startActivity('android.intent.action.MAIN', 
                    None, None, None, False, 
                    'com.twitter.android', 
                    'com.twitter.android.StartActivity'
                   )

see the syntax in the API Reference:

startActivity(
   String action,
   String uri[optional],
   String type[optional]: MIME type/subtype of the URI,
   JSONObject extras[optional]: a Map of extras to add to the Intent,
   Boolean wait[optional]: block until the user exits the started activity,
   String packagename[optional]: name of package. If used, requires classname to be useful,
   String classname[optional]: name of class. If used, requires packagename to be useful)
