I am new to Android UI designing. I have designed the screens in photoshop. How to extract the design assets? I tried using layercraft also. It didnt work as excepted by the developer. He asked to follow the guidelines.https://www.creativefreedom.co.uk/…/android-icon-size-guide/ I created the menu/launcher/ action bar icons. But the developer is saying the action bar icons are looking like corrupted and it is not even showing the preview in android studio. Please guide me. What's wrong in the attached image?
