Hi,

This is a know issue and we are currently working on it. 

Here is a possible workaround: Launch the app from the Navigator and accept permissions in the permission dialog (if any) and then close it. Restart loading from IDE.

I will create an issue in our issue tracker and post the link shortly so you can track its progress!

Thanks, Ram

I have the same problem. Fortunately I have a device for testing...

Here's something that has worked for me in some circumstances.

ssh to the sim/device (here's a guide to ssh'ing http://forums.crackberry.com/blackberry-playbook-f222/guide-ssh-your-playbook-640410/).  You need to be connected to the sim (or device) and be in developer mode. 

use pidin to see if your app is running (or pdebug).

slay -f pdebug

slay -f <your app>

sometime I have had to slay qconn and then reconnect.

I've noticed that my problems with the sim mostly come from suspending my laptop while in the middle of debugging.

Hi,

When you look at the error description at (<install location>/target/qnx6/usr/include/errno.h) it says

#define ENOEXEC          8  /* Exec format error                        */

Can you confirm if you are using the right NDK version (Ex. not the playbook NDK?) to deploy to the BB Dev Alpha device?

The only "solution" is reset device with BlackBerry manager, but its really annoying do that every time when this errors appear.

RIM should fix this bug soon because is annoying when programming

I also have similar problem! After first run of the app I get "unable to determine returned pid from launch" in IDE and this moment screen of device unfortunaly is black. But power button and volume buttons still works (I can see indication on screen). Looks like UI shell is crashed! The device restart or reset cant help because after this device always show only colored bubbles! Only one thing helped it's restore the device using BB Desktop Software but it's too long! And it will work only for first run after will be black screen. Help me please.

indeed its very annoying.

I've posponed my app's development until this gets fixed.

Everyone having this problem see here:

No fix until AFTER 2.1
