Thank you very much for using ArcGIS Runtime SDK for Android and reporting issues found in the SDK. Your feedback is very valuable and can help us to improve our SDK.
Issue #1: Removed toolbar
Generally, popup in 10.1.1 has been improved a lot to adapt and allow developers to utilize new components of Google Android SDK such as fragment and action bar. So, in order to allow developers have more controls over the UI, the toolbar and buttons has been removed from popup. It is very easy to add a toolbar back to the popup. You can refer to the popup samples which go with our SDK. Two popup samples can be found under the "Maps" category.
Issue #2: Documentation
That section should be removed. We will update the doc. Sorry for the misleading.
Issue #3: Change to isEditable() causing problem & Issue #4: Change to hasAttachments causing problem
isEditable() and hasAttachments() are determined by the backend feature service to which your ArcGISFeatureLayer is bound. When the feature service supports editing or has attachment, those two methods will return true accordingly. If a ArcGISFeatureLayer is constructed from FeatureSet, these two methods will always return false. We are adding new APIs and functionalities to support offline editing in our SDK. At this point we don't have any plan to change the behavior of ArcGISFeatureLayer.
We are still investigating the other issues. Reply to the other issues will be posted later.
Thanks again.
