我们如何切换MTP上更容易出现调试启用的Android 6.0设备上？ [英] How do we toggle on MTP more easily on a Debug-Enabled Android 6.0 device?
问题描述
在Android的6.0，<一个href=\"http://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-usb\">MTP不再自动工作的：
In Android 6.0, MTP no longer works automatically:
设备连接现在默认设置为充电-only模式。要访问设备及其通过USB连接的内容，用户必须明确授予权限这种互动。如果您的应用支持与设备上的USB端口的用户交互，考虑到交互必须显式启用。
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. If your app supports user interactions with the device over a USB port, take into consideration that the interaction must be explicitly enabled.
MTP需要至少每您在插入USB电缆，可能更频繁地超过该时间重新授权（超时？）。
MTP needs to be re-authorized at least every time you plug in the USB cable, and possibly more frequently than that (timeouts?).
启用USB调试，我发现让MTP共享设备上工作的唯一的解决办法是：
With USB debugging enabled, the only solution that I have found to get MTP sharing to work on the device is to:
- 走进设置>开发者选项
- 向下滚动到选择USB配置
- 该选项的值切换到任何的但的MTP，如仅充电（如果是在MTP现在）
- 该选项的值切换到MTP
- 刷新MTP客户端（例如，在Ubuntu 15.04，关闭并重新打开显示设备中的内容的窗口）
- Go into Settings > Developer options
- Scroll down to "Select USB Configuration"
- Switch the value of that option to anything but MTP, such as "Charging only" (if it is on MTP right now)
- Switch the value of that option to MTP
- Refresh your MTP client (e.g., on Ubuntu 15.04, close and re-open the window showing the contents of the device)
这是加剧的，当你试图用一个设备上的外部存储的文件进行操作。
This is aggravating when you are trying to work with a device's files on external storage.
是否有一个命令行的方式来获得MTP去，总之写UIAutomator测试，它可以自动上述过程的？或者说，有一些其他的方式来获得MTP在没有这种$ P $聚丙烯工艺的工作？
Is there a command-line way to get MTP going, short of writing a UIAutomator "test" that automates the above process? Or, is there some other way to get MTP to work without this sort of prep process?
推荐答案
我怀疑没有某种超能力的它不会是可能的： - （
I suspect it will not be possible without some sort of super power :-(
adb shell svc usb setFunction mtp
抛出 java.lang.SecurityException异常：无论是用户还是2000当前进程具有android.permission.MANAGE_USB 和 MANAGE_USB 是签名|特权许可。我提起这个作为问题＃193062 。它已投入状态的分配的并标记为的缺陷25596495 的
throws java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USB. and MANAGE_USB is a signature|privileged permission. I filed this as issue#193062. It has been put into state Assigned and labeled as Defect-25596495.
