# Banner & MREC Ads

> Integrate CloudX banner and MREC ads in Android apps

## Banner Ads (320x50)

<CodeGroup>
  ```kotlin Kotlin theme={null}
  class MainActivity : AppCompatActivity(), CloudXAdViewListener, CloudXAdRevenueListener {
      private lateinit var bannerAd: CloudXAdView

      private fun createBannerAd() {
          bannerAd = CloudX.createBanner(this, "your-banner-ad-unit-id")
          bannerAd.listener = this
          bannerAd.revenueListener = this

          val layoutParams = LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.WRAP_CONTENT,
              LinearLayout.LayoutParams.WRAP_CONTENT
          )
          layoutParams.gravity = Gravity.CENTER_HORIZONTAL
          findViewById<LinearLayout>(R.id.banner_container).addView(bannerAd, layoutParams)
      }

      override fun onDestroy() {
          super.onDestroy()
          bannerAd.destroy()
      }

      // CloudXAdViewListener callbacks
      override fun onAdLoaded(cloudXAd: CloudXAd) {
          Log.d("CloudX", "Banner ad loaded from ${cloudXAd.networkName}")
      }

      override fun onAdLoadFailed(adUnitId: String, cloudXError: CloudXError) {
          Log.e("CloudX", "Banner ad failed to load: ${cloudXError.message}")
      }

      override fun onAdClicked(cloudXAd: CloudXAd) {
          Log.d("CloudX", "Banner ad clicked")
      }

      override fun onAdExpanded(cloudXAd: CloudXAd) {
          Log.d("CloudX", "Banner ad expanded")
      }

      override fun onAdCollapsed(cloudXAd: CloudXAd) {
          Log.d("CloudX", "Banner ad collapsed")
      }

      // CloudXAdRevenueListener callback
      override fun onAdRevenuePaid(cloudXAd: CloudXAd) {
          Log.d("CloudX", "Banner bid-time revenue: ${cloudXAd.revenue} from ${cloudXAd.networkName}")
      }
  }
  ```

  ```java Java theme={null}
  public class MainActivity extends AppCompatActivity implements CloudXAdViewListener, CloudXAdRevenueListener {
      private CloudXAdView bannerAd;

      private void createBannerAd() {
          bannerAd = CloudX.createBanner(this, "your-banner-ad-unit-id");
          bannerAd.setListener(this);
          bannerAd.setRevenueListener(this);

          LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.WRAP_CONTENT,
              LinearLayout.LayoutParams.WRAP_CONTENT
          );
          layoutParams.gravity = Gravity.CENTER_HORIZONTAL;
          ((LinearLayout) findViewById(R.id.banner_container)).addView(bannerAd, layoutParams);
      }

      @Override
      protected void onDestroy() {
          super.onDestroy();
          if (bannerAd != null) {
              bannerAd.destroy();
          }
      }

      // CloudXAdViewListener callbacks
      @Override
      public void onAdLoaded(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "Banner ad loaded from " + cloudXAd.getNetworkName());
      }

      @Override
      public void onAdLoadFailed(@NonNull String adUnitId, @NonNull CloudXError cloudXError) {
          Log.e("CloudX", "Banner ad failed to load: " + cloudXError.getMessage());
      }

      @Override
      public void onAdClicked(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "Banner ad clicked");
      }

      @Override
      public void onAdExpanded(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "Banner ad expanded");
      }

      @Override
      public void onAdCollapsed(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "Banner ad collapsed");
      }

      // CloudXAdRevenueListener callback
      @Override
      public void onAdRevenuePaid(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "Banner bid-time revenue: " + cloudXAd.getRevenue() + " from " + cloudXAd.getNetworkName());
      }
  }
  ```
</CodeGroup>

Banner ads auto-refresh by default. To control refresh manually:

<CodeGroup>
  ```kotlin Kotlin theme={null}
  bannerAd.stopAutoRefresh()  // Stop auto-refresh
  bannerAd.load()             // Manually load a new ad
  bannerAd.startAutoRefresh() // Re-enable auto-refresh
  ```

  ```java Java theme={null}
  bannerAd.stopAutoRefresh();  // Stop auto-refresh
  bannerAd.load();             // Manually load a new ad
  bannerAd.startAutoRefresh(); // Re-enable auto-refresh
  ```
</CodeGroup>

Optional placement and custom data for tracking:

<CodeGroup>
  ```kotlin Kotlin theme={null}
  bannerAd.setPlacement("home_screen")
  bannerAd.setCustomData("level:5,coins:100")
  ```

  ```java Java theme={null}
  bannerAd.setPlacement("home_screen");
  bannerAd.setCustomData("level:5,coins:100");
  ```
</CodeGroup>

## MREC Ads (300x250)

<CodeGroup>
  ```kotlin Kotlin theme={null}
  class MainActivity : AppCompatActivity(), CloudXAdViewListener, CloudXAdRevenueListener {
      private lateinit var mrecAd: CloudXAdView

      private fun createMrecAd() {
          mrecAd = CloudX.createMREC(this, "your-mrec-ad-unit-id")
          mrecAd.listener = this
          mrecAd.revenueListener = this

          val layoutParams = LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.WRAP_CONTENT,
              LinearLayout.LayoutParams.WRAP_CONTENT
          )
          layoutParams.gravity = Gravity.CENTER_HORIZONTAL
          findViewById<LinearLayout>(R.id.mrec_container).addView(mrecAd, layoutParams)
      }

      override fun onDestroy() {
          super.onDestroy()
          mrecAd.destroy()
      }

      // CloudXAdViewListener callbacks (same as Banner)
      override fun onAdLoaded(cloudXAd: CloudXAd) {
          Log.d("CloudX", "MREC ad loaded from ${cloudXAd.networkName}")
      }

      override fun onAdLoadFailed(adUnitId: String, cloudXError: CloudXError) {
          Log.e("CloudX", "MREC ad failed to load: ${cloudXError.message}")
      }

      override fun onAdClicked(cloudXAd: CloudXAd) {
          Log.d("CloudX", "MREC ad clicked")
      }

      override fun onAdExpanded(cloudXAd: CloudXAd) {
          Log.d("CloudX", "MREC ad expanded")
      }

      override fun onAdCollapsed(cloudXAd: CloudXAd) {
          Log.d("CloudX", "MREC ad collapsed")
      }

      // CloudXAdRevenueListener callback
      override fun onAdRevenuePaid(cloudXAd: CloudXAd) {
          Log.d("CloudX", "MREC bid-time revenue: ${cloudXAd.revenue} from ${cloudXAd.networkName}")
      }
  }
  ```

  ```java Java theme={null}
  public class MainActivity extends AppCompatActivity implements CloudXAdViewListener, CloudXAdRevenueListener {
      private CloudXAdView mrecAd;

      private void createMrecAd() {
          mrecAd = CloudX.createMREC(this, "your-mrec-ad-unit-id");
          mrecAd.setListener(this);
          mrecAd.setRevenueListener(this);

          LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
              LinearLayout.LayoutParams.WRAP_CONTENT,
              LinearLayout.LayoutParams.WRAP_CONTENT
          );
          layoutParams.gravity = Gravity.CENTER_HORIZONTAL;
          ((LinearLayout) findViewById(R.id.mrec_container)).addView(mrecAd, layoutParams);
      }

      @Override
      protected void onDestroy() {
          super.onDestroy();
          if (mrecAd != null) {
              mrecAd.destroy();
          }
      }

      // CloudXAdViewListener callbacks (same as Banner)
      @Override
      public void onAdLoaded(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "MREC ad loaded from " + cloudXAd.getNetworkName());
      }

      @Override
      public void onAdLoadFailed(@NonNull String adUnitId, @NonNull CloudXError cloudXError) {
          Log.e("CloudX", "MREC ad failed to load: " + cloudXError.getMessage());
      }

      @Override
      public void onAdClicked(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "MREC ad clicked");
      }

      @Override
      public void onAdExpanded(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "MREC ad expanded");
      }

      @Override
      public void onAdCollapsed(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "MREC ad collapsed");
      }

      // CloudXAdRevenueListener callback
      @Override
      public void onAdRevenuePaid(@NonNull CloudXAd cloudXAd) {
          Log.d("CloudX", "MREC bid-time revenue: " + cloudXAd.getRevenue() + " from " + cloudXAd.getNetworkName());
      }
  }
  ```
</CodeGroup>

MREC ads also auto-refresh by default. Use the same refresh control methods as Banner ads.
