Change Ad Unit ID of AdView

[Dat Nguyen]

Could I use many Ad Unit Ids for the same AdView? I want to change Ad Unit Id at each screen. On iOS, it doesn't have any problem, but on Android, it goes crashed.

Thank you in advance.

Hi Dat,

You should definitely be able to use different Ad Units for the same AdView on Android. Could you show me your code?

Yes. Here's the code:

public static void setAdUnitID(String id)
{
     INSTANCE.adUnitID = id;
}

public static void initializeAdMob(String id)
{
     INSTANCE.adUnitID = id;
     INSTANCE.bottomAdView = new AdView(INSTANCE.mCurrentActivity);
     INSTANCE.bottomAdView.setAdSize(AdSize.BANNER);
     INSTANCE.bottomAdView.setAdUnitId(INSTANCE.adUnitID);
     INSTANCE.bottomAdView.setAdListener(INSTANCE);
}

public static void loadAd()
{
     final LinearLayout.LayoutParams adParams = new LinearLayout.LayoutParams(
         LinearLayout.LayoutParams.WRAP_CONTENT,

         LinearLayout.LayoutParams.WRAP_CONTENT);

     final AdRequest adRequest = new AdRequest.Builder()
     .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)

    .addTestDevice("xxxxxxxxxxxxxxxxxxxxxxx")

    .build();

     INSTANCE.mCurrentActivity.runOnUiThread(new Runnable()
     {
          @Override

         public void run()

         {

              INSTANCE.bottomAdView.setAdUnitId(INSTANCE.adUnitID);

              INSTANCE.bottomAdView.loadAd(adRequest);

              INSTANCE.bottomAdView.setBackgroundColor(Color.BLACK);

              INSTANCE.bottomAdView.setBackgroundColor(0);

              INSTANCE.mCurrentActivity.addContentView(INSTANCE.bottomAdView, adParams);

         }

    });
}

public static void showAd()
{
     INSTANCE.mCurrentActivity.runOnUiThread(new Runnable()
     {
          @Override

         public void run()

         {

              if (!INSTANCE.bottomAdView.isEnabled())

                   INSTANCE.bottomAdView.setEnabled(true);

              if (INSTANCE.bottomAdView.getVisibility() == 4 )

                   INSTANCE.bottomAdView.setVisibility(View.VISIBLE);

         }

    });
}

And app crashed with error log:

07-17 09:21:04.321: E/AndroidRuntime(12381): FATAL EXCEPTION: main

Dat, you really want to change those static methods to non-static and remove that presumably static INSTANCE attribute. Statics will bite you badly, it is also very non object oriented.

              if (INSTANCE.bottomAdView.getVisibility() ==</span

Dat - Can I see logs? Where is it crashing?

[Dat Nguyen]

Thank you guys.

Because of using JNI so I often use static methods. It's no problem if I set Ad Unit Id once on Adview, but I want to change it frequently. It crashed right after I call setAdUnitId()
method in loadAd(). Here's the log:

Hi Dat,

Try creating destroying the old AdView and creating a new one (in the same place) when you want to reset the Ad Unit.

[Dat Nguyen]

Thank you Amy. It seems that I have to destroy and create a new one. :( really don't expect this.

[Erol TOKALACOGLU]

Hi Amy,

Could you please share a part of code to solve this problem?

What do you mean with destroying and creating an AdView? Without changing the ad unit ID, the ads are serving normally.  But I need to use different ad units in my application, and I can't change the ad unit id et al.

if I use 

AdView adView = new AdView(this);

        adView.setAdUnitId("ca-app-pub-xxxx");

        adView.setAdSize(AdSize.SMART_BANNER);

        AdRequest adRequest = new AdRequest.Builder().build();

        adView.loadAd(adRequest);

Than 

Ad is not visible, not refreshing ad

If I use;

        AdView adView = (AdView)this.findViewById(R.id.adView);

        adView.setAdUnitId("XXXXX");

        AdRequest adRequest = new AdRequest.Builder().build();

        adView.loadAd(adRequest);

I got the error above..

Thank you for your time and consideration..

Regards..

You will not be able to change the adUnit for an adView. You can initialize and reference a new adView. The old adView should be garbage collected once it loses all references.
