Which layer type should be used in ArcGIS Runtime SDK for Android app

FatmaŞenol

Dear All,

I'm developing an Android Application using ArcGIS Runtime SDK for Android app but I'm getting

confused about which layer type should be used. One of my colleagues suggested me I should

use a webmap in developing an Android Application. Does it always have to be a webmap or

can I simply use a feature layer? I would appreciate if you could kindly share your experiences

and suggestions or a resource on this issue. Please note that all layers are hosted in our

ArcGIS Online organizational account.

My second question is that, how I can filter layers in android app. Typically, there are a number of

layers in a webmap and what I would like to do is filter the layers so that only selected layers are

displayed. So far, the only workaround I find is to go back and select another webmap

which makes the application not easy to use. Thank you for your help in advance.

Have a great weekend...

Hi Omur,

I think I am confused as to what you are looking to do based upon the questions asked.

Are you looking to find layers from your ArcGIS Online account in Android or are you looking to create layer objects with information from your ArcGIS Online account?

If you are looking to get information from your ArcGIS Online account, you should create a Portal object and then query that Portal object for feature layers within it:

Portal | ArcGIS Android 10.2.7 API

Here is a sample for connecting to Portal and querying it:

Portal Featured User Groups | ArcGIS for Developers

Hello Alexander,

I'm sorry for not writing to you earlier. As you might remember I'm trying to develop a native android application using ArcGIS Runtime SDK for Android as I mentioned before. I checked all the links you suggested in detail but since I don't have deep knowledge on Java I'm still trying to understand that how can I add individual layers into a map object. A undergrad student in computer science program in our university help me to develop the application but he also couldn't figure out how to do that

If you don't mind my asking, could you please kindly let me know more detailed information or perhaps a sample code regarding getting feature layers from our AGOL organizational Account ? At this moment, the application gets webmaps from AGOL account.

The URL of our AGOL account is https://iyte.maps.arcgis.com . I can create an account for you if you want to look at the file I've created. Additionally, I could also share the source code if you'd like to. Thank you

Best Regards

You do not need to use a webmap when developing an application. You can load individual layers at once into a map object.

This documentation should help you on which layer type to use:

Layer types—ArcGIS Runtime SDK for Android | ArcGIS for Developers

And this documentation should help you with loading the data:

Attribute Editor | ArcGIS for Developers (Look under the onCreate method.)

featureLayer = new ArcGISFeatureLayer( "http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Petroleum/KSFields/FeatureServer/0", MODE.SELECTION);

As for part 2 of this question, you may want to provide a section with check boxes that let you toggle the visibility on or off for each layer.

This documentation should help you figure out this portion:

Layer | ArcGIS Android 10.2.7 API
