enter image description here
Is It right ?? I'm getting the same output 1- on every prediction
Looks like your TFLite model generates a feature vector as a float array, which represents the characteristics of the image data.

The feature vector is usually considered as an intermediate data and it often requires to put the feature vectors again to the additional model for image classifications or some other tasks.

Compare and merge two different generic List

I have in my code two generic list, One containing some plans and other containing promocode details, the size of these lists can be different, the only common elements available in both list can be two, lets say id and name.
So my question is, how can i compare these two lists and only retain plans containing same id or name and also retain the plans which are not present in the promo list, without writing my own code? if not, what is the best compare and merge method.
I have tried converting it to Collection and used retainAll
sample plan json:
{"id":14,"name":"60 Day","description":"60 Day","validity":60,"is_active":true,"price":7}
sample promoplan json:
{"id":6,"name":"120 Day","description":"120 Day","original_price":12.0,"new_price":0.0"}
EDIT ultimate goal (ie matching id's of both list are retained with new price in the plan list and also the non matching id's with the existing price on plan list)
Any kind of help or hints will be greatly appreciated.

Android: different objects in one list

I am a new to android developing. I am developing an android app for a shopping mall...
i want to have a screen where a list is displayed. Name of the mall and its photo should be displayed in the first section with its short one line address...
In the next sections the products should be displayed in the same way....
Product photo, Product Name and its price...
Please suggest me what topics should i read to create such a screen....
could fragments be used to create this screen???
Thanks in advance...
There are many ways. Like you can create a Customized List view for each screen. You can first create an Array List of objects of MallClassPojo. Like:
ArrayList<MallClassPojo> mallList.
Where your MallClassPojo contains the getter setter methods for Mall name,Mall image url or resourceID and short description of mall. Pass this mallList to your adapter class. Retrieve the details and show them in your customised List View. The next screen can be prepared in the same way also.
Well then you can create an Array List of JSON objects. In a JSON Object you can add different data like in one object you can add the company data and in another you can add product data. Isn't it?

Android in app billing set product quantity

Is there any way I can create one product in android market and depending on different buttons clicked by user to set different quantity of the product?
As I know there isn't an option to send via android in app-billing quantity of one product, instead of this you can create for example three type of products, which will be something like that :
First Product : Quantity - 1
Second Product: Quantity - 3
Third Product : Quantity - 5
where all products are the same, just different quantities.
