I have a few devices I was testing on  and didn t want to manually get the DeviceID for each one  The answers here to programmatically get the DeviceIDs were not working for me  Missing zeros  which caused real ads to be shown instead of test ads   I put this in my Application class onCreate  and then exposed deviceId using a getter method so that it can be accessed throughout    Override public void onCreate                 super onCreate         String androidId    Settings Secure getString this getContentResolver    Settings Secure ANDROID ID       deviceId   MD5 androidId  toUpperCase                 public static String getDeviceId         return deviceId     private static String deviceId    And the MD5 method   public String MD5 String md5       try           java security MessageDigest md   java security MessageDigest getInstance  MD5            byte   array   md digest md5 getBytes             StringBuffer sb   new StringBuffer            for  int i   0  i  lt  array length    i                sb append Integer toHexString  array i   amp  0xFF    0x100  substring 1 3                      return sb toString          catch  java security NoSuchAlgorithmException e              return null      Then using this whenever I create an AdRequest object   if BuildConfig DEBUG         AdRequest adRequest   new AdRequest Builder              addTestDevice AdRequest DEVICE ID EMULATOR             addTestDevice Application getDeviceId               build         adView loadAd adRequest     else        AdRequest adRequest   new AdRequest Builder              addTestDevice AdRequest DEVICE ID EMULATOR             build         adView loadAd adRequest

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

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     Connect your device in USB debug mode to Android Studio      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  Filter the logcat with  device  as shown below to get test device     Read Admob ad testing on device - device IDs can change for more

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  lt  messageDigest length  i                  String h   Integer toHexString 0xFF  amp  messageDigest i                while  h length    lt  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
