android - onActivityResult With launchMode="singleTask"?

Question

When you try to startActivityForResult for Activity that has launchMode="singleTask"; it will not return any values with onActivityResult,and when you set launchMode="standard"; everything works fine, but the system requirements says this Activity must be singleTask, is there anyway to solve this?

Answer 1

The docs of the startActivityForResult say:

For example, if the activity you are launching uses the singleTask launch mode,
it will not run in your task and thus you will immediately receive a cancel result.

It seems there is no way to get around this.

If you are the developer of called Activity, then you can have it send a broadcast when some result is available. The calling Activity can then list to this broadcasts.
