Eclipse cannot find my Android 4.1.2 device

Question

I am trying to start only the introduction of "Hello World!" an application on my phone (Droid Razr Maxx) that runs android 4.1.2 jelly bean using Eclipse. I turned on USB Debugging, tried updating drivers / reinstalling drivers for my phone (I also have a Google USB driver), and tried to change the type of device that the computer reads from mass storage to a media device to the camera. Restarting did not work for anything (computer, eclipse, phone, meh). When I go to search for my device, it does not even appear, the form is empty: Fig. Windows "Select Android device." Any clue as to what might happen?

Answer 1

You need to install Motorola device manager. This will install the driver of your phone, I had the same problem with Motorola devices. You can download the device manager from here: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481

Answer 2

Assuming you have the drivers installed correctly and your computer reads your phone as an external device, I would recommend including “Unknown sources” or something similar in the “Security” section of your settings.

Also, for some reason, when I studied this material about my S3, I was told to turn on "Stay Awake", which can be found in the "Developer Options" section of your settings.

Let me know if it works.

Answer 3

Check HERE to install your mobile driver.
ADB should detect your device in order to verify this, open the command prompt window to change the directory to the android sdk folder with the cd , then go to platform-tools , then this adb kill-server command, then adb devices .

Answer 4

Disconnect the device from the computer. From your phone, open Settings, then tap Security. Check the Unknown sources box. Return. Scroll down to the developer options. Make sure USB debugging and enable layout locations are checked. Reconnect your device to the computer. Now it should find your device.
