When hitting <code>Ctrl+/</code> Android Development Studio would put line comment double slashes at the beginning of the line. Is there any way to make ADS put line comment preserving correct indentation?

You have to go to Settings → Editor → Code Style → JAVA. Select "Code Generation" tab. Deselect "Line comment at first column" option, on Comment Code section. <img src="https://i.stack.imgur.com/AntGq.png" alt="enter image description here"> This answer is based on Android Studio 2.3.
