I was working on implementing ads into my sketch, then I started getting this error.

I have reverted the sketch back to its original state, but it’s still getting the new error.

Paste your code so i might be able to run it and get it to work.

That might be the problem. Sometimes if you copy over 10 mbs of code it has errors NOT caused by you. Probably a misspelled word. that happened to me

I cant bring myself to share my entire sketch, as I am planning on releasing it on the play store.

When I implement this code into any of my pre-existing android sketches, it causes the errors mentioned above.  
But when I put it into a new sketch, it causes no errors, running fine.

```auto
import android.os.Bundle;
import android.view.Window;
import android.widget.RelativeLayout;
import android.app.Activity;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.AdSize;
import com.google.android.gms.ads.MobileAds;

public void setup() {
  fullScreen();
}

public void draw() {
  background(0);
}

@ Override
  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  //here you get the window
  Window window = getActivity().getWindow();
  RelativeLayout adsLayout = new RelativeLayout(this.getActivity());
  RelativeLayout.LayoutParams lp2 = new RelativeLayout.LayoutParams(
    RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.MATCH_PARENT);
  AdView adView = new AdView(this.getActivity());
  adView.setAdSize(AdSize.SMART_BANNER);
  adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
  adsLayout.addView(adView);
  AdRequest newAdReq = new AdRequest.Builder()
    .build();
  adView.loadAd(newAdReq);
  window.addContentView(adsLayout, lp2);
};

```

It needs a few additional things to work:

- [this file](https://drive.google.com/file/d/1tcx5j_2gjurrGa44WDraunafkTZP0d-H/view?usp=sharing) to be placed in the `/sketch/code` folder to work
- `<meta-data android:name="com.google.android.gms.version" android:value="8298000"/>`  
in the `<application>` bit of the android manifest
- Permissions for:
  - network state
  - wifi state
  - internet
  - read phone state

I may have figured something out.  
After exporting the project to android studio and doing the usual fixes required following that, I got this error:  
`Cannot fit requested classes in a single dex file (# methods: 68587 > 65536)`  
and somewhere else in the errors this:  
`The number of method references in a .dex file cannot exceed 64K.`

the solution to this normally according to [this stackoverflow](https://stackoverflow.com/questions/36785014/the-number-of-method-references-in-a-dex-file-cannot-exceed-64k-api-17) is to add ` multiDexEnabled true` in `build.gradle`

This worked but I want to continue working in processing for now.  
I will mark this as a solution and start a new topic for that.
