bjr, Si le lien est juste, voila comment acceder : ilya 2 sous repertoire sous "trunk" clique sur trunk "J2MEMapRouteAndroidEx" des sous repertoires s'affichent :
assets
bin
gen
res
src
J2MEMapRouteBlackBerryEx

et a droite ya le contenu de chaque sous rep .. donc tu trouvra :"androidManifext" et puis quand tu cliques sur res\layout tu trouvra main.xml .. et ainsi de suite copier tout ces fichier dans un nouveau android project et testes si vous avez un API Key pour google bien sure sinon aide moi just pour me corriger les erreurs en lisant le code :) Merci
