Why can't eclipse detect an Android device?

Question

Eclipse cannot detect my Android device, but it can work with an emulator. I have no problem setting up my Android device, as it works well on my old laptop.

any idea?

Answer 1

When the device starts, sometimes adb does not recognize it, because it is already running. So in this case you just need to reset adb from DDMS->Devices

Answer 2

Go to android-sdk/platform-tools/ with the promt command ...

write command .. adb devices (a list of connected devices is displayed)

If its device number does not appear, look at the device drivers on your system. And if the display, then just restart eclipse ..

Answer 3

Make sure that android: minSdkVersion is less than or equal to the version running on the phone. If it is higher, it will not appear in the "Select an Android device" section.

Answer 4

In addition, after installing the usb drivers, you may need to install the Android device in developer mode and enable USB debugging on your device before it sees adb or eclipse. From http://developer.android.com/tools/device.html

2.Enable USB debugging on your device. ◦ On most devices running Android 3.2 or older, you can find the option under Settings> Applications> Development.

In Android 4.0 and newer in Settings> Developer Options.

Note. In Android 4.2 and later, developer options are hidden by default. To make this available, go to Settings> About Phone and tap Create Number Seven Times. Return to the previous screen to find developer options.

Answer 5

In my case, I ran adb devices, and it showed my device, and it was unauthorized on the computer that I used. I went to the developer tools and turned off and then turned on USB debugging. He then offered me authorization for this computer, and then it worked fine.

Hope this helps someone.

Answer 6

Try connecting using the command line. / adb connect 192.168.xxx.xxxhaps555

Answer 7

If you use Linux, you will have to add your device to the /etc/udev/rules.d/51-android.rules file.

Have a look here: http://developer.android.com/tools/device.html . His paper on the use of hardware devices.

Didn't you turn on debug mode on your Android device?
If not, turn it on first. Then follow the steps in this article.

Answer 9

just install any driver - any compatibility software provided by your device provider, for example, Samsung, provide kies, Htc provide synchronization, etc.

Or check that your system or antivirus does not block it.
