Hi,
Targeting DOTNET 7.0 on Android
project1 having plugin.firebase runs fine, project2 with Plugin.MauiMTAdmob runs fine, but when I just install Plugin.MauiMTAdmob in project1 which has plugin.firebase, it is throwing me this error:

i'm entering in 3rd day and have not yet find any solution nor any one helped me. thats why i posted new question. i will delete previous question please help me what should i do to fix it. i did every thing from rebuilding to cleaning again and again.

Richard MacCutchan 12-Aug-23 11:34am

The key messages are:

Error JAVA0000 Error in obj\Debug\net7.0-android\lp\278\jl\classes.jar:com/google/android/gms/measurement/internal/zzfj.class:
Type com.google.android.gms.measurement.internal.zzfj is defined multiple times: 
obj\Debug\net7.0-android\lp\278\jl\classes.jar:com/google/android/gms/measurement/internal/zzfj.class,
obj\Debug\net7.0-android\lp\279\jl\classes.jar:com/google/android/gms/measurement/internal/zzfj.class

which suggests that the two plugins are linking to different versions of the named class. You need to check the documentation for the two packages to see if this is a known issue, or report it to the package owners.

suhail malik 2023 13-Aug-23 2:48am

i told owner about this behavior last night by commenting on his site, but next morning when I checked it again I could not find my comment, can u guide me to alternate solution regarding admob in maui, how can I achieve this, i will deeply appreciate Now i am entering 5th day

Richard MacCutchan 13-Aug-23 3:15am

Sorry, I have not used either of these plugins, so i cannot offer any useful suggestions.

Richard MacCutchan 13-Aug-23 3:17am

I just tried admob in maui - Google Search[^] and there appear to be plenty of resources available on the subject. Indeed the first find is one by Microsoft.
