通過USB連接檢查USB調試狀態

Question

尋找的方法來檢查，如果在開發者選項設置狀態USB調試的開啟/關閉（任何狀態信息），同時通過USB連接。

最近檢查了adb shell getprop沒有結果。

干杯

Answer 1

如果關閉 USB 調試，則無法使用 ADB，因此無法通過它獲取任何信息。

為了將 adb 與通過 USB 連接的設備一起使用，您必須在設備系統設置中的開發人員選項下啟用 USB 調試。

參考：
http://developer.android.com/tools/help/adb.html#Enabling

您可以調用adb devices並檢查結果。 如果列表為空，則設備沒有啟用該選項。 否則結果將是這樣的：

List of devices attached
XXXXXXXXXXXXXX  device

Answer 2

在終端

 adb devices -l
List of devices attached
2e2a0cb1               device usb:338952192X product:PD2065 model:V2065A device:PD2065 transport_id:3
...

其中usb表示：Android 設備已通過USB連接
