Why do I have errors for android_textColor, android:text and <ImageView in my activity_main.xml finder?

I have three errors which I don't understand:

error: Error: Color value not valid -- must be #rgb, #argb, #rrggbb, or #aarrggbb (at 'textColor' with value '#').

Missing contentDescription attribute on image (under <ImageView)

[I8N] Hardcoded string "Enlighten me!" should @string resource

  1. It means you must use correct format to specify your color. Please refer to this link

  2. When you use imageView, XML file would require you to set content Description. EX: android:contentDescription="@string/content_description_background"

  3. This says don't hardcode your string. Your string must be organized into string.xml for better usage such as internalization. Please refer to this link

Thanks Nic! I changed them, but then they came up as errors. I guess they were warnings, and then became errors :/
