Solution for those working with Huawei phones - You will get this error when ADB interface is not installed  Check if you have installed Huawei HiSuite  USB driver gets installed when you install HiSuite  I suppose this is true for most of the new phones that come with a Sync Software   If the ADB interface is installed on your computer you should see  Android Composite ADB Interface  under Android Phone in your Device Manager as shown in this picture

For me  this ended up being because I had the wrong SDK level installed  new version of Android Studio installed the SDK for Android 10  whereas I have a device that runs only Android 8 1   While Android Studio would  recognize  the device and display a string in the  devices  menu instead of just saying that no device was connected  installing the right SDK level for my device ended up changing the string to something recognizable  my device s model name  and allowed me to actually run my app over ADB

I have done numerous ways of handling that issue  Finally it has worked  I am using LG Optimus II  but I believe the following steps are generic to other Android devices as well    Step 1   Make sure your device is enabled for development  If yes  go to Step 2  otherwise go to Settings  gt  About phone and tap Build number seven times which is magic number  -    Now Developer Options is available in the Settings   Step 2   Before you plug your device to PC  Go to Settings  gt  Developer Options and select USB Connection method   Step 3   Plug the phone to the PC  you are given options for the USB Connection method  and please select Internet connection  Make sure you have connected to the Internet  By the way  I have changed MTP to PTP  it did not work for me  Therefore  I tried Internet connection mode  then it worked   Step 4   Run the app in the Android Studio  it will ask you to authorize the device for development  and select YES    Step 5   Run the application via Android Studio and choose the device  not emulator  and BINGO  Welcome to Android development board

In addition to the above configurations  I had to set deployment target to  Open Select Deployment Target Dialog   run once  choosing my device from the options listed   and from then on Android Studio was able to see my device even after changing the deployment setting back to  USB Device   My SWAG is that since Android Studio uses its own internal cache to find your device  it has to be initialized first

I had a big problem with my Samsung S10 Plus as it was not detecded by Android Studio on my Macbook even if I did all what is required to be detected  that is to say    Enable developer mode  7 taps on Build version in Android settings  Enable USB debugging   What I did is to start  Android File Transfer  on my Macbook and the magic happened  A popup appeared on my device asking if I want to authorize an USB access to it  I clicked  Yes  always  and now Android Studio can detect my device on my Mac

Did you try to configure the  Media Mode  in  Camera  PTP   instead of  Media device  MTP    This is sometimes solving the issue  Its in the USB Computer Connection options of your Android device  you should see an  authorize  dialog then   Update 04 2017  looks like it has been fixed in Android 7 1 2
