Perhaps the documentation needs to be updated? As of right now, it says:
"Note: this function schedules the task on a queue for a single background thread or pool of threads *depending on the platform version*. " ... and makes no mention of the target sdk setting in the manifest. Still, an app with targetSdkVersion 14 or 15 running on a 3.* device will still be getting a pool of threads. -- K 21 апреля 2012 г. 1:39 пользователь Dianne Hackborn <[email protected]>написал: > Sorry yes it is API 13, I turned around the logic of the code when I > glanced at it: > > // If the app is Honeycomb MR1 or earlier, switch its AsyncTask > // implementation to use the pool executor.
