Situation.

Once I downloaded the  native_template_example and native_platform_example  projects from the github link and run pub get, in order to make the application run, in both cases the emulator shows the screen, but when I press the refresh ad button I get the errors described at the end of the post.

It should be noted that my application (it is not the same as the downloaded ones) I was able to implement correctly in tests, the Ads banner but when trying to do the nativeADs it gave me the same error. Thinking it was a problem in my code, I did the above and it also returns a very similar error.

native template error:

I've been looking for a solution on the internet for weeks and I can't find it, please help me to solve the issue.

It should be noted that if I followed the manual into:

Hi Josue,

Thank you for reaching out to us.

Upon checking our sample app (https://github.com/googleads/googleads-mobile-flutter/tree/main/packages/google_mobile_ads/example), we're able to load ads on it, and wasn't able to encounter the error you're encountering. Can you confirm if you're able to replicate it in our sample app or only in your sample app project? In addition to that, can you also provide us the following information below?

• Sample app project if not reproducible in our sample app
• Steps to replicate
• App ID
• Ad unit ID
• Device name and version you're using

If the file(s) you are looking to share are less than 25mb in total you can attach them to this case on your next reply. If you are having trouble attaching your file to this case or if your file(s) are larger than 25mb, you can share your files with me by performing the following steps:

Thank you so much for help me.

In fact I am using your project without making any changes.

<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-3940256099942544~3347511713"/>

final String _adUnitId = Platform.isAndroid
? 'ca-app-pub-3940256099942544/2247696110'
: 'ca-app-pub-3940256099942544/3986624511';

Device name and version: ADV emulator, the exact characteristics will be located at the end of this post.

I still have problems, there must be something wrong with my configuration of the Intellij Idea programming IDE or in the use of an Android emulador. Please help.

I downloaded the link you sent me from github, opened the full path and performed the following steps:

1. Run "Pub get" on each of the projects to install the references
2. I configured Run/Debug of 4 projects:

• Example:             packages\google_mobile_ads\example\lib\main.dart
• NativeTemplate:  samples\admob\native_template_example\lib\main.dart
• NativePlataform:  samples\admob\native_platform_example\lib\main.dart  
• Banner:                 samples\admob\banner_example\lib\main.dart

In the case of Example, when executing I get the Multidex error, so I changed build.grandle to minSdkVersion 21 and compiled the project correctly

Example console message:

Hello Josue,

We will have to share this to the wider team to provide assistance on this. Rest assured that one of our team will reach out to you.

Hi Josue,

Thank you for providing that information. I see you are using an emulator that is a Pixel 6 Pro. Does that emulator have the Google Play Store? If not, can you try creating an emulator that does and see if you can reproduce the issue? If possible, can you also try replicating your issue on a real Android device.

Thanks,
Justin

[Josue Tomala]

Thank you so much.

I just changed the emulator to Pixel 4, (it has a play store), with the same Tiramisu API 33 System and it actually worked perfectly.

Both the demo projects and my project.

Thank you so much
