I am using Eclipse Mars Version 4.5.2. I am trying to access the setAppDataDirectory on the ArcGISRuntime class, but it does not come up as a method. the only methods that are valid are the static methods RenderEngine and License. I have the import statement for com.esri.runtime.ArcGISRuntime.
I just tested ArcGISRuntime 10.2.4 with Eclipse 4.5.1. It worked.
Does it compile if you use the method? It should.
Works fine. It was a developer's memory fault issue. Had the call outside my method.
