"*Curiouser and curiouser*!" *Cried Alice* Running your code on my GNex with official 4.0.2 I get this:
04-21 00:41:08.327 I/ParallelTasks(14355): A started 04-21 00:41:18.335 I/ParallelTasks(14355): A ended 04-21 00:41:18.335 I/ParallelTasks(14355): B started 04-21 00:41:28.335 I/ParallelTasks(14355): B ended 04-21 00:41:28.335 I/ParallelTasks(14355): C started 04-21 00:41:38.343 I/ParallelTasks(14355): C ended 04-21 00:41:38.343 I/ParallelTasks(14355): D started 04-21 00:41:48.335 I/ParallelTasks(14355): D ended 04-21 00:41:48.343 I/ParallelTasks(14355): E started 04-21 00:41:58.343 I/ParallelTasks(14355): E ended Note the timestamps. Here is my test, same idea really: http://codetidy.com/2565/ and it also shows that the default execute() on my GNex with 4.0.2 is serialized: 04-21 00:51:22.788 I/TestAsyncTask(14899): testDefaultExecutor 04-21 00:51:22.788 I/TestAsyncTask(14899): onPreExecute 0 04-21 00:51:22.788 I/TestAsyncTask(14899): onPreExecute 1 04-21 00:51:22.788 I/TestAsyncTask(14899): onPreExecute 2 04-21 00:51:22.788 I/TestAsyncTask(14899): onPreExecute 3 04-21 00:51:22.788 I/TestAsyncTask(14899): onPreExecute 4 04-21 00:51:22.788 I/TestAsyncTask(14899): doInBackground 0 04-21 00:51:27.796 I/TestAsyncTask(14899): doInBackground 1 04-21 00:51:32.796 I/TestAsyncTask(14899): doInBackground 2 04-21 00:51:37.796 I/TestAsyncTask(14899): doInBackground 3 04-21 00:51:42.804 I/TestAsyncTask(14899): doInBackground 4 04-21 00:51:47.804 I/TestAsyncTask(14899): done 04-21 00:51:47.804 I/TestAsyncTask(14899): testThreadPoolExecutor 04-21 00:51:47.804 I/TestAsyncTask(14899): onPreExecute 0 04-21 00:51:47.804 I/TestAsyncTask(14899): onPreExecute 1 04-21 00:51:47.804 I/TestAsyncTask(14899): onPreExecute 2 04-21 00:51:47.804 I/TestAsyncTask(14899): onPreExecute 3 04-21 00:51:47.804 I/TestAsyncTask(14899): onPreExecute 4 04-21 00:51:47.804 I/TestAsyncTask(14899): doInBackground 0 04-21 00:51:47.804 I/TestAsyncTask(14899): doInBackground 2 04-21 00:51:47.804 I/TestAsyncTask(14899): doInBackground 1 04-21 00:51:47.804 I/TestAsyncTask(14899): doInBackground 3 04-21 00:51:47.811 I/TestAsyncTask(14899): doInBackground 4 04-21 00:51:52.811 I/TestAsyncTask(14899): done Again, note the timestamps (although the order is obvious). On an Asus Tranformer with 4.0.3, I am getting the same results, the default execute is serial. Sanity check on a Sony Tablet S with 3.2.1, the default execute uses a thread pool: 04-21 01:10:22.870 I/TestAsyncTask( 1002): testDefaultExecutor 04-21 01:10:22.880 I/TestAsyncTask( 1002): onPreExecute 0 04-21 01:10:22.880 I/TestAsyncTask( 1002): onPreExecute 1 04-21 01:10:22.880 I/TestAsyncTask( 1002): doInBackground 0 04-21 01:10:22.880 I/TestAsyncTask( 1002): onPreExecute 2 04-21 01:10:22.880 I/TestAsyncTask( 1002): onPreExecute 3 04-21 01:10:22.890 I/TestAsyncTask( 1002): onPreExecute 4 04-21 01:10:22.890 I/TestAsyncTask( 1002): doInBackground 4 04-21 01:10:22.890 I/TestAsyncTask( 1002): doInBackground 3 04-21 01:10:22.890 I/TestAsyncTask( 1002): doInBackground 2 04-21 01:10:22.890 I/TestAsyncTask( 1002): doInBackground 1 04-21 01:10:27.890 I/TestAsyncTask( 1002): done 04-21 01:10:27.890 I/TestAsyncTask( 1002): testThreadPoolExecutor 04-21 01:10:27.890 I/TestAsyncTask( 1002): onPreExecute 0 04-21 01:10:27.890 I/TestAsyncTask( 1002): onPreExecute 1 04-21 01:10:27.890 I/TestAsyncTask( 1002): onPreExecute 2 04-21 01:10:27.900 I/TestAsyncTask( 1002): onPreExecute 3 04-21 01:10:27.900 I/TestAsyncTask( 1002): onPreExecute 4 04-21 01:10:27.900 I/TestAsyncTask( 1002): doInBackground 0 04-21 01:10:27.900 I/TestAsyncTask( 1002): doInBackground 1 04-21 01:10:27.900 I/TestAsyncTask( 1002): doInBackground 3 04-21 01:10:27.900 I/TestAsyncTask( 1002): doInBackground 4 04-21 01:10:27.900 I/TestAsyncTask( 1002): doInBackground 2 04-21 01:10:32.900 I/TestAsyncTask( 1002): done 04-21 01:10:32.900 I/ParallelTasks( 1002): A started 04-21 01:10:32.900 I/ParallelTasks( 1002): B started 04-21 01:10:32.910 I/ParallelTasks( 1002): D started 04-21 01:10:32.910 I/ParallelTasks( 1002): E started 04-21 01:10:32.910 I/ParallelTasks( 1002): C started 04-21 01:10:42.910 I/ParallelTasks( 1002): B ended 04-21 01:10:42.910 I/ParallelTasks( 1002): C ended 04-21 01:10:42.910 I/ParallelTasks( 1002): A ended 04-21 01:10:42.910 I/ParallelTasks( 1002): E ended 04-21 01:10:42.910 I/ParallelTasks( 1002): D ended -- K 21 апреля 2012 г. 0:21 пользователь Mark Murphy <[email protected]>написал: > 2012/4/20 Kostya Vasilyev <[email protected]>: > > The default is definitely serial on my GNex with 4.0.2. > > > > Did they revert it again for the 4.0.3 that you have? > > Here's how I am testing it (sloppy code, but it meets the need): > > -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
