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? alt text

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.

This is probably better than calling `com.google.android.gms.internal.cm.l(Context ctx)` which is the internal obfuscated method (in version 4.0.30) that returns returns the ID in question – Amr Mostafa Dec 07 '13 at 15:05
Thank you for this! Just to put it into Python, `import hashlib; hashlib.md5(android_id.lower()).hexdigest().upper()`. This way you can just download an app to show your Android ID and take the MD5 of that. – douggard Jan 27 '14 at 00:34

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.

After filtering using the above mentioned terms "adRequest", you'll find a line - " 12-19 17:48:25.615: I/Ads(2132): To get test ads on this device, call adRequest.addTestDevice("D9XXXXXXXXXXXXXXXXXXXXXXXXXXXXX");". Just copy paste the code and have fun. – Ashok Goli Dec 19 '12 at 12:28

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

I was looking while running Unity Dev Build and this one worked. Thanks. — Avisek Chakraborty, Jul 25 '20 at 19:09

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();

To get the Hash Device ID

inside the oncreate

String android_id = Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID);
        String deviceId = md5(android_id).toUpperCase();
Log.i("device id=",deviceId);

then add this class for md5 ()

public String md5(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++)
                hexString.append(Integer.toHexString(0xFF & messageDigest[i]));
            return hexString.toString();

        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
        return "";
    }

Thanks, but there is actually a subtle bug in your md5() function. The line where you append to hexString should be this: `hexString.append(String.format("%02X", 0xFF & messageDigest[i]));` Your implemention will give incorrect output on byte values of 15 or less since the leading zero will not be output. — Ant, Aug 09 '17 at 00:07
your md5() generate wrong ID, expected 561600E037F6E9EEBE405B487459D786 but 56160E037F6E9EEBE405B487459D786 — Foobnix, Jan 19 '18 at 14:21

To get the device id, connect your phone to USB and open logcat in android studio Use the code below (make sure you have USB debugging enabled in your device). Then open any app (download any random app from play store) which has google Ad. In the Logcat type "set" as shown in the image. Your device id is shown highlighted in the image as

setTestDeviceIds(Arrays.asList("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")).

Use the Test Device in your code as shown

val adRequest = AdRequest
        .Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice("CC9DW7W7R4H0NM3LT9OLOF7455F8800D")

If you are displaying ads using XML layout and if you already have "ads:testDevices=" in your layout XML file, AdMob will NOT print the "To get test ads on this device..." message in the LogCat output. Take that out and then you will see the LogCat message.

Here is a nice tutorial on how to find device id in LogCat: http://webhole.net/2011/12/02/android-sdk-tutorial-get-admob-test-device-id/

If you are testing your app on actual device then you can try this small android app which gives you the device id:

https://play.google.com/store/apps/details?id=pe.go_com.admobdeviceidfinder&hl=en

You will get the hashed device id directly. Hope this helps.

I am not sure this is what the question was about. As I remember from the emulator you cannot install from the Play store. Probably a more programmatical solution (or the relevant parts of the source of this app) would be better. – Gábor Bakos Mar 06 '15 at 06:48

Another easiest way to show test ads is to use test device id for banner to show admob test ads for all devices. "ca-app-pub-3940256099942544/6300978111" . This admob test ads id was noted in the admob tutorial of google: link. This is the quote from the above link:

This is the test device id for interstitial "ca-app-pub-3940256099942544/1033173712" . This also was used in interstitial tutorial

If you don't get it in the logcat just put any device id and load you Ads and run your app then go to the log you will get it like that I/Ads: Use AdRequest.Builder.addTestDevice("XXXXXXXXXXXXXXXXXXXXXXXXX") to get test ads on this device. after that put it and run your application again.

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 < array.length; ++i) {
            sb.append(Integer.toHexString((array[i] & 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);
}

Works to this way:

    mInterstitial.setAdUnitId("your id");
    AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice("some words")
    .build();
    mInterstitial.loadAd(adRequest);

After run the app... Go in Logcat put in Verbose put in the search field AdRequest, so the id device shows donw.

.addTestDevice("put the id here");

    return adRequest.build();
}



    private static String MD5(String md5) {

        try {
            java.security.MessageDigest md = java.security.MessageDigest.getInstance("MD5");
            byte[] array = md.digest(md5.getBytes("UTF-8"));
            StringBuilder sb = new StringBuilder();
            for (byte anArray : array) {
                sb.append(Integer.toHexString((anArray & 0xFF) | 0x100).substring(1, 3));
            }
            return sb.toString();
        } catch (java.security.NoSuchAlgorithmException ignored) {
        } catch(UnsupportedEncodingException ignored){
        }
        return null;
    }

    private static String getDeviceId(Context context) {
        try {

        } catch (Exception e) {
            return "";
        }

Usage:

Kotlin solution:

To get the current device ID:

private fun getDeviceIdForAdMobTestAds(context: Context): String? {
    val md5 = Settings.Secure.getString(context.contentResolver, Settings.Secure.ANDROID_ID)
    try {

            sb.append(Integer.toHexString(array[i].toInt() and 0xFF or 0x100).substring(1, 3))
        return sb.toString()
    } catch (e: NoSuchAlgorithmException) {
    }
    return null
}

Usage:

val deviceIds = arrayListOf(AdRequest.DEVICE_ID_EMULATOR)
getDeviceIdForAdMobTestAds(context)?.let { deviceIds.add(it.uppercase(Locale.ROOT)) }
