设置plane_mode_on已从android.provider.Settings.System移至android.provider.Settings.Global，返回只读值

Question

I am trying to load image in activity from another one , When I click on the button to start activity it shows me black screen and never shows and give me this warning

 Setting airplane_mode_on has moved from android.provider.Settings.System to android.provider.Settings.Global, returning read-only value.

here is the activity .....

any help please

Answer 1

Settings.System.AIRPLANE_MODE_ON was deprecated in API level 17.

You can see the reference here

You have to replace Settings.System.AIRPLANE_MODE_ON by AIRPLANE_MODE_ON on your isAirplaneModeOn method importing the one with Global in Settings
