Increase the Min API Level to Android 7.0. Then Resolve Android Dependencies, and then Build.

SOLVED

[Mikhael_stardust]

I was able to solve the export problem, but now that I installed the APK on my cell phone, the game stops as soon as it starts.
Does anyone know what could be happening?

@Mikhael_stardust use debugging on mac for android build. see here

@pinaeong

me :
unity 2021.3.16.f1
Google Mobile Ads Unity Plugin v7.3.1

Google admob brought me to this problem , but you saved me.

• Delete folder: <PROJECT_FOLDER>\Library\Bee\Android

I just did this. And build is succussed. Also I can see video ads now. THANK YOU!

Anyway, what is that folder??

Its work

[JunmoChoi]

Set it to at min API level 24 or higher.

If it still happens, inside gradleTemplate.properties
android.useAndroidX=true
android.enableDexingArtifactTransform=false
Check if it is set.

If you do useAndroidX=true , the ASM7 library is included, and here android.enableDexingArtifactTransform=false seems to conflict with that option.

If you delete android.enableDexingArtifactTransform=false, it will build normally.
android.enableDexingArtifactTransform=false is sometimes included in the ads sdk.

I increased the min API Level to Android 7.0 and worked for me. And make sure Android dependencies are resolved.

Deleting the <PROJECT_FOLDER>\Library\Bee\Android did the trick for me
Thank you !

And then try building the game, if the issue still persists, try following the below steps:

• Delete folder: <PROJECT_FOLDER>\Library\Bee\Android
• Android Resolver > Force Resolve
• Build again

Even if the above steps do not work then do the following:

• Delete “Android” folder present in the location : <PROJECT_FOLDER>\Library\Bee\Android

• Increase the min API Level to Android 7.0

• Android Resolver > Force Resolve

• Build

This worked for me. Thank a ton

Well, if someone is stuck with the same issue, you can try doing the following :

Add the below content in Custom Progaurd :

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

-injars       bin/admob-unity-plugin.jar
-outjars      bin/proguard-admob-unity-plugin.jar
#-libraryjars  <java.home>/lib/rt.jar
#-libraryjars  /libs/android-support-v4.jar
-libraryjars  <android.sdk>/platforms/android-16/android.jar
-libraryjars  /libs/GoogleAdMobAdsSdk-6.4.1.jar
-libraryjars  /libs/Unity-4.1-androidplayer.jar
-printusage   bin/proguard.txt
-printmapping bin/proguard-out.map

-renamesourcefileattribute SourceFile
-dontusemixedcaseclassnames
-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                SourceFile,LineNumberTable,*Annotation*,EnclosingMethod

-keep,includedescriptorclasses public class com.google.** { *; }

# Keep - Library. Keep all public and protected classes, fields, and methods.
-keep public class * {
    public protected <fields>;
    public protected <methods>;
}

# Keep names - _class method names. Keep all .class method names. This may be
# useful for libraries that will be obfuscated again with different obfuscators.
-keepclassmembers, allowshrinking class * {
    java.lang.Class class$(java.lang.String);
    java.lang.Class class$(java.lang.String, boolean);
}

# Keep names - Native method names. Keep all native class/method names.
-keepclasseswithmembers, allowshrinking class * {
    native <methods>;
}

# Also keep - Enumerations. Keep the special static methods that are required in
# enumeration classes.
-keepclassmembers enum  * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keepclassmembers class * extends java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

And then try building the game, if the issue still persists, try following the below steps:

• Delete folder: <PROJECT_FOLDER>\Library\Bee\Android
• Android Resolver > Force Resolve
• Build again

Even if the above steps do not work then do the following:

• Delete “Android” folder present in the location : <PROJECT_FOLDER>\Library\Bee\Android

• Increase the min API Level to Android 7.0

• Android Resolver > Force Resolve

• Build

Just these two steps solved my problem <PROJECT_FOLDER>\Library\Bee\Android and next: Android > Force Resolve, the unity team should have people like you on the team, thanks!.

Delete folder: <PROJECT_FOLDER>\Library\Bee\Android

I have just increase the minimum API level to 8.0 and it works for me and then APK exported successfully.

I have not deleted any other folder.
