Comment obtenir le chemin complet du fichier à partir de l'URI
Je voudrais obtenir le chemin complet du fichier, à partir d'un URI. L'URI n'est pas une image, mais un fichier de musique, mais si je le fais comme pour la solution MediaStore, cela ne fonctionnera pas si l'utilisateur de l'application sélectionne, par exemple, Astro comme navigateur, au lieu de Music Player. Comment résoudre ce problème?
Utilisation:
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
ou
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
La méthode PathUtil ne fonctionnera qu'en dessous de oreo et si elle est plus probable qu'elle risque de planter, car dans oreo nous n'obtiendrons pas l'id, mais le chemin d'accès complet dans data.getData (), il vous suffit donc de créer un fichier. depuis uri et récupérez son chemin depuis getPath () et divisez-le. Voici le code de travail: -
Uri uri = data.getData();
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).
Le code ci-dessus fonctionnera dans oreo et s'il est inférieur à oreo, alors PathUtil fonctionnera. Merci!
String filePath=PathUtil.getPath(context,yourURI);
