Cómo obtener la ruta completa del archivo desde URI (8)
Me gustaría obtener la ruta completa del archivo, desde un URI. El URI no es una imagen, pero es un archivo de música, pero si lo hago como la solución MediaStore, no funcionará si el usuario de la aplicación selecciona, por ejemplo, Astro como navegador, en lugar de reproductor de música. ¿Cómo puedo solucionar esto?
El método PathUtil solo funcionará debajo de oreo y si está en oreo de lo que es probable que se cuelgue porque en oreo no obtendremos el id sino toda la ruta en data.getData () así que todo lo que necesitamos hacer es crear un archivo desde uri y obtener su camino de getPath () y dividir it.below es el código de trabajo: -
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).
El código anterior funcionará en oreo y si está debajo de oreo, PathUtil funcionará. ¡Gracias!
String filePath=PathUtil.getPath(context,yourURI);

Me costó mucho tratar de resolver esto con Xamarin. De las sugerencias anteriores, se me ocurrió esta solución.
private string getRealPathFromURI(Android.Net.Uri contentUri)
{
string filename = "";
string thepath = "";
Android.Net.Uri filePathUri;
ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);
if (cursor.MoveToFirst())
{
int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
filename = filePathUri.LastPathSegment;
thepath = filePathUri.Path;
}
return thepath;
}
Prueba esto.
public String getRealPathFromURI(Uri contentUri)
{
String[] proj = { MediaStore.Audio.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

Utilizar:
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
o
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
