Tutorial: Howto implement AdMob/MoPub/any kind of ad in Android App

[Jo nas]

Hey Codenameone community,

since I implemented MoPub I'm earning ~20-50 times the money that I earned with vserv.mobi, although I'm only doing this in Android. You can see an example on how these banners/interstatials looks like in my app: Scientific Calculator cFunction.

Because the only 'built-in' ad network in cn1 is the very bad paying vserv.mobi network, here is a small bullet-point tutorial on how to implement advertising (banners/interstatials) for Android with MoPub mediating to AdMob/Millennial Media. In general all ad networks can be implemented somehow like this, but I think MoPub is the best solutions for its mediation options. So here is how it goes:

• Get the Android sources of your codenameone project ('include source') (can only be done when you're a paying cn1 user)
  
• Register with MoPub/AdMob/Millennial Media
  
• Import the Android sources of your app in eclipse
  
• Download the MoPub full SDK
  
• Add the MoPub SDK to your project and add the manifest entries like described here
  
• Add mopub/lib/*.jars to your libs directory in eclipse
  
• Add in proguard.cfg:

  -libraryjars libs/GoogleAdMobAdsSdk-6.4.1.jar
  -libraryjars libs/MMSDK.jar
  -libraryjars libs/android-support-v4.jar
  -keep class com.nuance.** { *; }
  -keep class com.millennialmedia.** { *; }
  -keep class com.google.** { *; }
  -keepclassmembers class com.millennialmedia.android.* { 
  public *; 
  } 
  -keep class com.millennialmedia.android.**
  -dontwarn com.millennialmedia.android.NVASpeechKit*

Then for banner ads:

• Go to /src/codename1/impl/android/AndroidImplementation.java and replace initSurface() by this:
  

    public static MoPubView moPubView;

/**

* init view. a lot of back and forth between this thread and the UI thread.

*/

private void initSurface() {

//layout for whole screen

RelativeLayout rl = new RelativeLayout(activity);

rl.setLayoutParams(new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT));

//add banner

moPubView = new MoPubView(getContext());

moPubView.setAdUnitId(<your mopub id>); // Enter your

// Ad Unit

// ID from

moPubView.loadAd();

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); // You might want to tweak these to WRAP_CONTENT

lp.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

lp.addRule(RelativeLayout.CENTER_HORIZONTAL);

final int dps = 50;

final float scale = getContext().getResources().getDisplayMetrics().density;

final int pixels = (int) (dps * scale + 0.5f);

//add implementation 

relativeLayout = new RelativeLayout(activity);

RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);

        lp2.setMargins(0, 0, 0, pixels);

        relativeLayout.setLayoutParams(lp2);

relativeLayout.setFocusable(false);

myView = new AndroidView(activity, AndroidImplementation.this);

myView.setVisibility(View.VISIBLE);

relativeLayout.addView(myView);

myView.setVisibility(View.VISIBLE);

int id = activity.getResources().getIdentifier("main", "layout", activity.getApplicationInfo().packageName);

RelativeLayout root = (RelativeLayout) LayoutInflater.from(activity).inflate(id, null);

rl.addView(relativeLayout);

root.addView(rl);

root.addView(moPubView, lp);

activity.setContentView(root);

myView.requestFocus();

}

• Go to /res/layout/main.xml in your project and replace it with this:
  

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="#ff000000" >

</RelativeLayout>

For interstatials: 

• Go to /src/com/codename1/impl/android/CodenameOneActivity.java and follow the points in chapter 4: http://help.mopub.com/customer/portal/articles/285186

Hope this helps someone!

Hi Jonas

Is MoPub still working for you?
