App freezes at splash screen on mobile device, not on FlashBuilder's emulator - apache-flex

Question

I want to include Mobile AutoCompleteCombobox made by Flextras (http://www.Flextras.com), into my project to give to user a rapid way to fill some textInput. So I integrated it sucessfully in my code, I can tell that because the result is nice when I launch FlexBuilder's mobile device simulator : It launch my app code to test it including the component (I used the sample code provided into sources).
After that test, I wanted an apk file to test this app under a real mobile device. So I builded successfully the swf and finally the apk files ! But my app fails when I launch it under mobile device : It freezed at my splash picture for unlimited time ! Have you ever seen this problem and have you even resolved this one ? Because I searched in the big exchange forum which is named Stackoverflow.com, but I can't find any similar issue !
Please could you give me a way to be efficient ?
This following lines are here to explain two parts of my method : firstly to compile swf Flex file, secondly to build the apk Android package.
1) Launched with cmd.exe console, to compile :
ant -buildfile Build_myAppProject.xml actionCompiler
2) Launched with cmd.exe console, to build the app file :
adt -package -target apk -storetype pkcs12 -keystore [MyCertificateFile.p12] -storepass hyebiell1234 [MyOutputFile.apk] [MyAppInfoDescriptor.xml] [MyAppCompiledFile.swf] -extdir [MyANEAndLibrariesFolder] -C src\assets -C src\assets\img -e src[MySqliteFileToCopyIntoPackage] [MySqliteFileToCopyIntoPackage] -e src\icone50x50.png icone50x50.png -e src\icone72x72.png icone72x72.png -e src\icone128x128.png icone128x128.png -e src\icone144x144.png icone144x144.png -e src\icone512x512.png icone512x512.png

Lately I launched the app with LogCat and I get this :
