PlayBook NDK 2.0 compile run Publish project to simulator error: Downloading and starting the application

Running the run configuration in the NDK development tool runs in playbook emulator with the following error:

"Downloading and starting the application ..." has encountered a problem.

Unable to determine returned PID from launch.

One possible cause:

NDK 2.0 When creating a project, the default target is Device-debug. Build out binary code is arm, not x86, naturally can not run on the x86 CPU playbook emulator.

Workaround:

NDK, right-click menu Build Configurations---Set Active--Simulator-debug

Select the right mouse button menu again to Build Project

Now the project HelloWorld3 has x86/le binaries.

Run the Configuration again, it can be running ~ ~ ~
