android emulator doesn't display my first 'standard' helloWorld app

The standard new app HelloWorld doesn't run as it in the Android emulator.

On Apple Mac, I created an AVD : Nexus7-4.3-JellyBean ( Android 4.3 API 18 , CPU/ABI ARM(armabi-v7a) RAM 343 VM Heap 32 / Storage 200 MiB / SD Card 128 MiB)

then running HelloWorld from Eclipse ADT , I get the following in the console log ( no error stated ...)

[2013-12-07 16:11:22 - HelloWorld] ------------------------------
[2013-12-07 16:11:22 - HelloWorld] Android Launch!
[2013-12-07 16:11:22 - HelloWorld] adb is running normally.
[2013-12-07 16:11:22 - HelloWorld] Performing com.example.helloworld.MainActivity activity launch
[2013-12-07 16:11:22 - HelloWorld] Automatic Target Mode: launching new emulator with compatible AVD 'Nexus7-4.3-JellyBean'
[2013-12-07 16:11:22 - HelloWorld] Launching a new emulator with Virtual Device 'Nexus7-4.3-JellyBean'

The emulator is launched, it displays the Android log, then unlocking it with Fn F2 I get the home page and I can see the list of apps BUT HelloWorld is not there.

Why can't I see any information or at least any error?

Solution
