MoneyBox Android Technical Task

A small application for viewing investment products.

Part A

Bug 1 - Layout does not look as expected

• Constraints added to all TextInputLayouts
• Edit text views within TextInputLayouts and TextInputLayouts within match parent and the TextInputLayouts match parents
• correct spacing between edges margin of 12dp left and right
• email TextInputLayout with a 48dp margin at the top

Bug 2 - Validation is incorrect

• Email matching android email matcher
• allValid within allFieldsValid() is true by default
• once allValid changes to false it remains false and no login called
• Changes to false every failed validation

Bug 3 - Animation is looping incorrectly

• set minimum and maximum frames based the firstAnim Pair<Int, Int> range respectively
• set an animation completion listener and wait for first animation play to finish
• on completion of first animation change the min and max frames based on secondAnim Pair<Int, Int> range
• play animation with new min and max frames
