Bonsoir,
1) Pour l'écriture sur la carte micro SD je suis tombé sur ce billet très interessant (je mets l'url et l'extrait citant google) :

"Hey all, in KitKat we introduced APIs that let apps read/write file in app-specific directories on secondary storage devices, such as SD cards.
We heard loud and clear that developers wanted richer access beyond these directories, so in Lollipop we added the new ACTION_OPEN_DOCUMENT_TREE intent. Apps can launch this intent to pick and return a directory from any supported DocumentProvider, including any of the shared storage supported by the device. Apps can then create, update, and delete files and directories anywhere under the picked tree without any additional user interaction. Just like the other document intents, apps can persist this access across reboots.
This gives apps broad, powerful access to manage files while still involving the user in the initial selection process. Users may choose to give your app access to a narrow directory like "My Vacation Photos," or they could pick the top-level of an entire SD card; the choice is theirs."
> en 2 mots les applis pourront solliciter l'utilisateur pourqu'il leur indique l'arboresence sur la carte micro SD
à partir de laquelle l'application pourra écrire, éditer détruire etc.
il sera possible à l'utilisateur de choisir une arborescence restreinte : photo_vacances_Noel ou /extSDCard soit toute la carte mSD
il reste à attendre pour en bénéficier que chaque application intègre cette évolution et la propose dans leur prochaine release
