Question

This is my code for uploading image on server,This work fine with other projects but i got error when i am using this code in my project //method to get the file path from uri

 public String getPath(Uri uri) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, 
            null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();

        cursor = getContentResolver().query(
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        cursor.close();

        return path;
    }

android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0 at this line : String paths = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA)); I have to upload image to server. — dipali

You just got problem because cursor is null at that line. You have to check null when work with cursor:

String path = ""; 
if(cursor != null && cursor.moveToFirst()){
    path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA)); 
    cursor.close();
}

actually it's not null, it's empty. as per OP comment the error is android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0 ...

If the path is empty, you need to check before convert to byte[] and pass into multipart. If the path is empty, you get no image. Can you post ur code when you convert path to byte and when you use multipart to post image ?

I worked on many kind of android device. MediaStore.Images.Media.DATA not return real path for image on all device. Tomorrow i will give you an class that i wrote to get image path. This class work on almost device.
