How to add Adsmob

Finally got ads on my apps, I thought it's going to be hard but the documentation is so easy to understand, just go to documentation first if stuck go to my notes. I think I had a trouble, it says that my campaign is still running on adsword so I had to fix that by removing the campaign then it would let me register for admob. After registering it takes 2 days to be verified.

Dashboard - https://apps.admob.com/

update :

Little bit of tutorial just the main point, tried banner ads, rewarded ads but didn't get to try interstitial ads (on my future task)

#build.gradle
implementation 'com.google.android.gms:play-services-ads:19.1.0'

#manifest
<!-- Sample AdMob App ID: ca-app-pub-3940256099942544~3347511713 -->
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>

# value string
<string name="ad_unit_id">ca-app-pub-3940256/6300</string>

Initialize after on create

MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });

create the view in here I use the responsive ads

<FrameLayout
        android:id="@+id/ad_view_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_alignParentBottom="true" />

In on create after initialize

	adContainerView = findViewById(R.id.ad_view_container);
        // Step 1 - Create an AdView and set the ad unit ID on it.
        adView = new AdView(this);
        adView.setAdUnitId(getString(R.string.ad_unit_id));
        adContainerView.addView(adView);
        loadBanner();

then make private function in the activity

private void loadBanner() {
        // Create an ad request. Check your logcat output for the hashed device ID
        // to get test ads on a physical device, e.g.,
        // "Use AdRequest.Builder.addTestDevice("ABCDE0123") to get test ads on this
        // device."
        AdRequest adRequest =
                new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                        .build();

        AdSize adSize = getAdSize();
        // Step 4 - Set the adaptive ad size on the ad view.
        adView.setAdSize(adSize);

        // Step 5 - Start loading the ad in the background.
        adView.loadAd(adRequest);
    }

    private AdSize getAdSize() {
        // Step 2 - Determine the screen width (less decorations) to use for the ad width.
        Display display = getWindowManager().getDefaultDisplay();
        DisplayMetrics outMetrics = new DisplayMetrics();
        display.getMetrics(outMetrics);

        float widthPixels = outMetrics.widthPixels;
        float density = outMetrics.density;

        int adWidth = (int) (widthPixels / density);

        // Step 3 - Get adaptive ad size and return for setting on the ad view.
        return AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(this, adWidth);
    }

REWARDED ADS

Also I tried the rewarded ads, this is when you want the user willingly open your ads in exchange of maybe reward.

Activity

rewardedAd = new RewardedAd(this,
                "ca-app-pub-3940256099942544/5224354917");

        RewardedAdLoadCallback adLoadCallback = new RewardedAdLoadCallback() {
            @Override
            public void onRewardedAdLoaded() {
                // Ad successfully loaded.
            }

            @Override
            public void onRewardedAdFailedToLoad(int errorCode) {
                // Ad failed to load.
            }
        };
        rewardedAd.loadAd(new AdRequest.Builder().build(), adLoadCallback);

        button_support.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (rewardedAd.isLoaded()) {
                    Activity activityContext = DetailActivity.this;
                    RewardedAdCallback adCallback = new RewardedAdCallback() {
                        @Override
                        public void onRewardedAdOpened() {
                            // Ad opened.
                        }

                        @Override
                        public void onRewardedAdClosed() {
                            // Ad closed.
                        }

                        @Override
                        public void onUserEarnedReward(@NonNull RewardItem reward) {
                            // User earned reward.
                        }

                        @Override
                        public void onRewardedAdFailedToShow(int errorCode) {
                            // Ad failed to display.
                        }
                    };
                    rewardedAd.show(activityContext, adCallback);
                } else {
                    Log.d("TAG", "The rewarded ad wasn't loaded yet.");
                }
            }
        });

View

<Button
        android:id="@+id/supportUs"
        android:layout_width="wrap_content"
        android:layout_gravity="center"
        android:text="Support Us"
        android:layout_height="wrap_content" />
