How can I get device ID for Admob

Question

I'm using Eclipse to develop applications for android, and I want to integrate Admob to make money. The tutorial says I should watch the LogCat to find ID, but where is it?

When I run in either the test mode or the real mode, sometimes the eclipse will notify that Ads returned, yet it does not show in the emu... can anyone explain?

The accepted answers will work if you are only testing on the Emulator or on a few devices, but if you are testing on a plethora of devices, you may need some means of prorammatically adding the running device's device ID.

The following code will make the current running device into an adview test device programmatically

...
    if(YourApplication.debugEnabled(this)) //debug flag from somewhere that you set
    {

        String android_id = Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID);
        String deviceId = md5(android_id).toUpperCase();
        mAdRequest.addTestDevice(deviceId);
        boolean isTestDevice = mAdRequest.isTestDevice(this);

        Log.v(TAG, "is Admob Test Device ? "+deviceId+" "+isTestDevice); //to confirm it worked
    }

You need to use the md5 of the Android ID, and it needs to be upper case. Here is the md5 code I used

public static final String md5(final String s) {
    try {
        // Create MD5 Hash
        MessageDigest digest = java.security.MessageDigest
                .getInstance("MD5");
        digest.update(s.getBytes());
        byte messageDigest[] = digest.digest();

        // Create Hex String
        StringBuffer hexString = new StringBuffer();
        for (int i = 0; i < messageDigest.length; i++) {
            String h = Integer.toHexString(0xFF & messageDigest[i]);
            while (h.length() < 2)
                h = "0" + h;
            hexString.append(h);
        }
        return hexString.toString();

    } catch (NoSuchAlgorithmException e) {
        Logger.logStackTrace(TAG,e);
    }
    return "";
}

EDIT: Apparently that MD5 method isnt perfect, and it was suggested to try https://stackoverflow.com/a/21333739/2662474 I no longer need this feature so I havent tested. Good luck!

If you are running admob ads on an emulator then there is no ID. just use the AdManager method and set it to TEST_EMULATOR like the logcat says. If you run on an actual device with usb debugging and watch the logcat, the ID will appear in there.

• Is your app published on Play store -- with live ads:

If your app is on Play store showing live ads -- you can't use live ads for testing -- add your device ID in code to get test ads from Admob on your real device. Never use live ads during development or testing.

To get real device ID in logcat,

1. Connect your device in USB debug mode to Android Studio

2. Open any app on your device which shows live ads from Admob: On the connected device, if you have your app downloaded from play store(showing live ads) open that app or else open any other app that shows live Admob ads. Your device should have an internet connection.

3. Filter the logcat with 'device' as shown below to get test device

Something similar to Google Ads, from the documentation:

public AdRequest.Builder addTestDevice (String deviceId)

Causes a device to receive test ads. The deviceId can be obtained by viewing the logcat output after creating a new ad. For emulators, use DEVICE_ID_EMULATOR.

for example my Test Device id displayed in LogCat is "B86BC9402A69B031A516BC57F7D3063F":

AdRequest adRequest = new AdRequest.Builder() 
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("B86BC9402A69B031A516BC57F7D3063F")
        .build();
