Android – Why is Eclipse’s Android Device Chooser not showing the Android device

adbandroideclipse

I am using the Android plugin for Eclipse, and when I try to run my program using a real device through the Android Device Chooser, my phone is not listed as a device. I have updated Eclipse, all of the Android packages, and the USB driver, but it still isn't showing up. My phone is running Android 2.1, which is also the target version listed in the Eclipse project.

Also it happens that the device shows up as an unknown target and the serial number as question marks as shown in the screenshot.

Did you try from your command line (assumed linux)

adb devices

If you got a lot of question marks

List of devices attached
??????????????    device

Check what is the vendor ID of your device:

lsusb 
> Bus 003 Device 006: ID 04e8:689e Samsung Electronics Co., Ltd

Vendor ID is '04e8' in this case.

You need to add your device to USB list

sudo vim /etc/udev/rules.d/51-android.rules

and put this line (use your own vendor ID).

SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"

Alternatively try the following syntax as pointed out by mcordaro and Yekmer Simsek referring to the documentation

SUBSYSTEM=="usb", ATTR{idVendor}=="04e8", MODE="0666", GROUP="plugdev"

save it, and then

sudo chmod a+r /etc/udev/rules.d/51-android.rules
sudo service udev reload

and it should work now.

Android Device Chooser — device not showing up

First, make sure that the Android ADB can "talk to" your device.

Open a Windows Command Prompt (cmd.exe)/Mac Terminal.
Go to the folder (via cd) where ADB.exe is in, e.g, C:\Android\android-sdk\platform-tools.
Type adb devices

If your device is listed (serial number is displayed), go to the second check. Otherwise, this means ADB currently can't talk to your device. There're many reasons which can cause the problem, try:

In your device, turn on "USB Debugging Mode" in Settings -> Application -> Development.
In your device, turn on "Allow installation of non-market Applications" in Settings -> Application -> Development.
Restart your Windows/Mac.
Restart the Android device.
In Windows/Mac, reinstall device drivers.

Second, make sure you set the "Deployment target selection mode" to manual:

In Eclipse Package Explorer view, right click your Project, select Run As -> Run Configurations...
In Run Configurations dialog, under Android Application. If your app doesn't exist, double click Android Application to create a new configuration, give it a suitable name (e.g. your app). Make sure this configuration is selected.
On the right area, for Android tab, make sure your project displayed under Project; for Target tab, select "Always prompt to select device" or "manual".
Click "Apply" and close the Run Configurations dialog.
The next time when you Run your app, you should see your list of devices.

Your device still can't display? Ok. Third, make sure your "Project Build Target" Android version is supported in your Device.

Check your device's Android version. In your device, select Settings->About Device.
Check Android version of your project. Right click your project->Properties->Android->ProjectBuildTarget.
Make sure that it's not newer than your device's version.

Android – unique Android device ID

Settings.Secure#ANDROID_ID returns the Android ID as an unique for each user 64-bit hex string.

import android.provider.Settings.Secure;

private String android_id = Secure.getString(getContext().getContentResolver(),
                                                        Secure.ANDROID_ID);
