Get Path Of Gallery Image Xamarin?

I am trying to get the path of Gallery Image. I am getting the path of the image which is stored in internal storage but not of the external storage. I have also enabled the read-w

Solution 1:

I want to get the selected image path which I have choose from gallery

The problem is that change Android.Net.Uri to path, here is an solution :

privatestringGetPathToImage(Android.Net.Uri uri)
{
    string doc_id = "";
    using (var c1 = ContentResolver.Query(uri, null, null, null, null))
    {
        c1.MoveToFirst();
        string document_id = c1.GetString(0);
        doc_id = document_id.Substring(document_id.LastIndexOf(":") + 1);
    }

    string path = null;

    // The projection contains the columns we want to return in our query.string selection = Android.Provider.MediaStore.Images.Media.InterfaceConsts.Id + " =? ";
    using (var cursor = ContentResolver.Query(Android.Provider.MediaStore.Images.Media.ExternalContentUri, null, selection, newstring[] { doc_id }, null))
    {
        if (cursor == null) return path;
        var columnIndex = cursor.GetColumnIndexOrThrow(Android.Provider.MediaStore.Images.Media.InterfaceConsts.Data);
        cursor.MoveToFirst();
        path = cursor.GetString(columnIndex);
    }
    return path;
}

When you choose a picture from gallery :

ChoosePhoto();
...
 protectedoverridevoidOnActivityResult(int requestCode, Result resultCode, Intent data)
{
    base.OnActivityResult(requestCode, resultCode, data);
    if (requestCode == 0)
    {
        var uri = data.Data;
        var path = GetPathToImage(uri);
        System.Diagnostics.Debug.WriteLine("Image path == " + path );
        //My result is this ==> [0:] Image path == /storage/emulated/0/DCIM/Camera/IMG_20170813_223324.jpg
    }
 }

Most important, when you use this method, maybe you will come across this problem :

Java.Lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=21975, uid=10417 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()

When API >= 23, Requesting Permissions at Run Time, users grant permissions to apps while the app is running, not when they install the app. You should check if you have android.permission.READ_EXTERNAL_STORAGE permission, if not, you need to request the permissions.
