Android Studio 将物理设备识别为 Null? [英] Android Studio recognizes physical Device as Null?

问题描述

我一直在开发 Android 应用程序(SDK 最低版本 14)，并且我已经使用 Samsung Galaxy 2 和 Nexus 7 等平板电脑对其进行了正常测试.但是，当我尝试运行该应用程序时(通过在AndroidStudio 中单击运行)，AS 无法识别平板电脑信息，如下图所示.

I've been developing an Android Application for Android (SDK min version 14) and I have testing it normally with tablets such as Samsung Galaxy 2 and Nexus 7. However when I tried to run the application (by clicking run in AndroidStudio), AS does not recognise the tablet information, which is shown in the picture below.

有趣的是，如上图所示，当它的Android版本是4.2.2时，AS也在检测设备sdk为API 1平板电脑已在开发人员选项中设置为接受USB 调试"，我尝试重新启动平板电脑并重新启动 AS，但仍然遇到相同的问题( 一切正常nexus 7 和三星 Galaxy 2).

The interesting thing is that as shown in the picture above, AS is also detecting the device sdk as API 1 when it's Android version is 4.2.2 The tablet is already set to accept "USB debugging" in the developer options, I'have tried rebooting the tablet, and restarting AS, but still I get the same problem(everything is fine with nexus 7 and Samsung Galaxy 2).

我正在使用的平板电脑/设备是VeryKool"T742

The tablet/device I'm working on is a "VeryKool" T742

Environment information:
 OS: ubuntu
 AndroidStudio version: 0.8.6

 Tablet Android version:4.2.2
 Tablet Kernel version: 3.4.5
 App min SDK: 14

推荐答案

Ok 所以我终于找到了问题，显然在这个设备上你必须设置连接为相机(即使在 USB 调试已经启用之后)

Ok So I finally found the problem, apparently on this device you have to set to connect as camera(even after usb debugging is already enabled)
