How do we toggle on MTP more easily on a Debug-Enabled Android 6.0 device?

阅读更多关于 How do we toggle on MTP more easily on a Debug-Enabled Android 6.0 device?

问题 In Android 6.0, MTP no longer works automatically: Device connections through the USB port are now set to charge-only mode by default. To access the device and its content over a USB connection, users must explicitly grant permission for such interactions.

MTP needs to be re-authorized at least every time you plug in the USB cable, and possibly more

How to capture images in background using Camera2 api?

And before Android M, using the camera from the background is not recommended, since you'll block any foreground app from using it (the app will just get an error trying to open the camera, and generally will crash as a result). Otherwise, the camera API works the same. You'll need to
