android getContentResolver返回值的问题

Question

最近学了下面的代码，运行时报错数组越界，检查发现newUriList为空，再进一步检查发现是因为getContentResolver.insert的返回值newUri的权限，路径以及id之间没有“/"，求大神解释这怎么解决，谢谢

            Uri uri=Uri.parse("content://com.example.databasetest.provider/book");
            ContentValues values=new ContentValues();
            values.put("name", "A clash of kings");
            values.put("author", "Gerorge Martin");
            values.put("pages", 1040);
            values.put("price", 22.85);
            android.net.Uri newUri=getContentResolver().insert(uri, values);
            Log.d("newUriList","newUri is "+newUri.toString());
            List<String> newUriList=newUri.getPathSegments();
            if(newUriList.isEmpty()){
                Log.d("newUriList","newUriList is empty");
            }else{
                Log.d("newUriList","newUriList has "+newUriList.size()+" elements");
                Log.d("newUriList","The first element of newUriList is "+newUriList.get(0));
                Log.d("newUriList","The second element of newUriList is "+newUriList.get(1));
            }
            newId=newUriList.get(1);
