Android Offline Tiles, User Credentials and Tokens

BillMyers1 — Fri, 06 Nov 2015 01:11:59 GMT

I'm developing an app using the ArcGIS Runtime SDK for Android. I'm accessing tiled basemaps from arcgis.com using the following code which works fine.

UserCredentials creds = new UserCredentials();

creds.setUserToken("token", "referer");

String mapUrlUsaTopo = "https://services.arcgisonline.com/arcgis/rest/services/USA_Topo_Maps/MapServer";

mBasemapLayer = new ArcGISTiledMapServiceLayer(mapUrlUsaTopo, creds);

But... when I attempt to download the map tiles for offline use I get the following error: com.esri.core.io.EsriSecurityException: Message: Unable to generate token. Details: 'username' must be specified., 'password' must be specified.

Here's the download code:

String tileUrlUsaTopo = "https://tiledbasemaps.arcgis.com/arcgis/rest/services/USA_Topo_Maps/MapServer";

final ExportTileCacheTask exportTileCacheTask = new ExportTileCacheTask(tileUrlUsaTopo, creds);

Is the only option hard coding the username and password?

It would be great if the Esri Android Dev team would respond.

Andrew from Esri support was very helpful. To do "application" authentication (without a user name and password) using your app id and secret key you need something like the code below. However, there is a bug (BUG-000092420) in the android sdk and code below does not work at the present time. I'm being told that the fix may make in into the Quartz final release.

private class AppLoginTask extends AsyncTask<Void, Void, Void> {

@Override
protected Void doInBackground(Void... params) {

Log.d("MyApp", "AppLoginTask");

Portal p = new Portal("https://www.arcgis.com", null);

try {

p.doOAuthAppAuthenticate(APP_SECRET, APP_ID, new CallbackListener<Portal>() {

@Override
public void onCallback(Portal portal) {

Log.d("MyApp", "login callback");

//mCreds = new UserCredentials();
mCreds = portal.getCredentials();

setMapDataMode(MapDataMode.ONLINE);

}

@Override
public void onError(Throwable throwable) {

Log.e("MyApp", "login error");

}

});

} catch (Exception e) {

Log.d("MyApp", "login exception");

e.printStackTrace();

}

return null;

}

@Override
protected void onPostExecute(Void results) {

Log.d("MyApp", "login post execute");

//setMapDataMode(MapDataMode.ONLINE);
}

}

Does anyone know if this works now in version 100.0.0?

Lite level licensing worked for me:

License your app—ArcGIS Runtime SDK for Android | ArcGIS for Developers

Is there a specific level of licensing that you are looking to use?
