如何使用 Xamarin for Visual Studio 在真实的 Android 设备上进行调试？

Question

I've found a few links but they don't explain how this is done. I can debug using Xamarin Studio IDE but that IDE (no offense) is lame compared to Visual Studio 2012.
Using Visual Studio 2012, there appears to only be option to select an emulator to debug. So how do I get it to debug on my real device via USB (I already have USB Debugging = true)?

Answer 1

I'm using Visual Studio 2017 with a OnePlus.

In order get debugging working I did the following.

1. Go to Settings > About phone and tap Build Number repeatedly until developer mode is enabled
2. Go into Settings > Developer options and turn USB debugging ON
3. Connect you phone to your PC via USB. I had to plug my phone into my PC's onboard USB port, not my USB hub as this did not work
4. You should be prompted to trust your PC (trust it)
5. Fire up Visual Studio
6. Open your solution and your device should now be available.

Side note: I have noticed that sometimes it also depends on the cable you use. If you still have no luck, perhaps try another cable.

Answer 2

You will get a confirmation prompt on the android device to ask if the PC is allowed to connect. It's easy to miss this if your device's screen has gone to sleep.

Answer 3

I'm using Visual Studio 2015 with Xamarin and the only way I can get it to recognize my Galaxy S4 is to turn USB debugging off and back on again while VS is running. This is required everytime I wish to use this phone with VS. I've never had to do this with Android Studio.

Answer 4

1 - Original drivers (Example: http://androidmtk.com/download-samsung-usb-drivers )

2 - Enable Developer's Options on mobile (for example on android 4.2.2, perform 7 click on "mobile info" - "serial number")

3 - USB debugging on your Mobile Developer's Options too

Answer 5

我也遇到过类似的问题，我通过安装特定于我手机型号的 USB 驱动程序解决了这个问题。

Answer 6

tl;dr Install drivers if you haven't already done so.

As mentioned in one of the comments above I installed the device specific USB driver (LG drivers are here ) and it solved my problem. It now works perfectly.

I was under the (incorrect!) impression I wouldn't need to install the drivers to enable debugging. I could already connect my device to my laptop to view files etc. and hence thought drivers were unnecessary.

Answer 7

Once everything else is ready, the device could appear under the "Not compatible devices" list. This could be happening if the "Minimun Android version" set in your project is higher than android version you have in your device. If so, you can set the "Minimun Android version" in the android manifest

Answer 8

I set my Mobile connection in USB charging mode and enable USB debugging. It may ask for driver installation, after driver installation disconnect the mobile and reconnect it, now this should show in Visual studio device list for debugging.

Answer 9

It looks like Xamarin Android Player is not installed. You will need to install this.
