使用put/get取得或設定Android Settings.Global數值

若有需要讀寫Android系統內Java所儲存的global數值，以下以display_outputmode_auto作為範例

取得

settings get global display_outputmode_auto

設置

settings put global display_outputmode_auto 1
settings put global display_outputmode_auto 0

問題

如果出現下面錯誤表示需要高於system的權限
settings put global display_outputmode_auto 1
