layout attributes changed

[thenishchalraj]

Using Gravity#LEFT and Gravity#RIGHT can lead to problems when a layout is rendered in locales where text flows from right to left. Use Gravity#START and Gravity#END instead.
NOTE: If your minSdkVersion is less than 17, you should add both the older left/right attributes as well as the new start/right attributes.
On older platforms, where RTL is not supported and the start/right attributes are unknown and therefore ignored, you need the older left/right attributes. There is a separate lint check which catches that type of error. (Note: For Gravity#LEFT and Gravity#START, you can use these constants even when targeting older platforms, because the start bitmask is a superset of the left bitmask. Therefore, you can use gravity="start" rather than gravity="left|start".)

This android:layout_toEndOf="@+id/loader" was not needed in the linear layout which is horizontally oriented already.
The given layout_param is not defined for the given layout, meaning it has no effect. This usually happens when you change the parent layout or move view code around without updating the layout params. This will cause useless attribute processing at runtime, and is misleading for others reading the layout so the parameter should be removed.

BTW I must say, it's a nice library
