L'application Android se coince lors du balayage dans Viewpager, et le tiroir de navigation dans le dispositif guimauve

Question

J'utilise ViewPager dans mon tiroir de navigation tout fonctionne très bien dans les dispositifs autres que les dispositifs guimauve. dans les dispositifs guimauve lorsque je clique sur le bouton bascule ou glisser le tiroir de navigation (dans les deux sens) se sentir coincé (pépin) dans le flux, aussi quand je glisser le viewpager dans différents onglets a également trouvé le coincé. Cela a été trouvé seulement dans le dispositif de guimauve. S'il vous plaît aidez-moi ,, merci à l'avance ....

c'est mon code

vue contrôle fragments mise en page, évitez les images .jpeg (utiliser des images .png) ... contrôle le pager de vue avec s quelques fragments simples, si cela fonctionne en douceur vérifier les vues de mise en page ..
