How to Get Device Id for Admob

How can I get device ID for Admob

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.

addTestDevice is used for showing Admob test ads for development.so in deployment remove addTestDevice from your adRequest,i.e. make your adRequest as

Get AdMob test device ids for both iOS and Android in Flutter project

After a while of looking through logs, I realized there are some missing steps in Flutter's package explanation.

First, Firebase needs to be linked to you AdMob app, AND you need to re-download the GoogleService-Info.plist file for iOS and the google-services.json for Android.

After that, in iOS you need to go into Settings -> Privacy -> Advertising and disable Limit Ad Tracking. This will allow for the ID to be printed.

How to get a hashed device id for testing admob on ios

I figured out how to generate the AdMob device ID:
Just compute the MD5 of the advertisingIdentifier.

#import <AdSupport/ASIdentifierManager.h>
#include <CommonCrypto/CommonDigest.h>

- (NSString *) admobDeviceID
{
    NSUUID* adid = [[ASIdentifierManager sharedManager] advertisingIdentifier];
    const char *cStr = [adid.UUIDString UTF8String];
    unsigned char digest[16];
    CC_MD5( cStr, strlen(cStr), digest );

    NSMutableString *output = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];

    for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)
        [output appendFormat:@"%02x", digest[i]];

    return  output;

}

Getting device ID to show Admob Interstitial Ads

Here is what I usually use on my apps :

public static String getMD5(String inputText){
     String md5 = "";
     try{
        MessageDigest digester = MessageDigest.getInstance("MD5");
        digester.update(inputText.getBytes());
        md5 = new BigInteger(1, digester.digest()).toString(16);
     }
     catch(Exception e){}
     return md5;
}



public String getDeviceId(){
     String androidID = Settings.Secure.getString(getContentResolver(),Settings.Secure.ANDROID_ID);
     String deviceID = getMD5(androidID).toUpperCase();
     return deviceID;
}

Where to put test device IDs in google_mobile_ads package?

Use updateRequestConfiguration callback on the MobileAds instance, and provide test device IDs.

MobileAds.instance
  ..initialize()
  ..updateRequestConfiguration(RequestConfiguration(
    testDeviceIds: <String>[],
  ));
