Unity

1.Throwing dex 64k reference error when packaging Android APK.

Take version 2019.4.8f1 as an example, modify file /Applications/Unity/Hub/Editor/2019.4.8f1/PaybackEngines/AndroidPlayer/Tools/GradleTemplate/launcherTemplate.gradle, add "multiDexEnabled true".

android {
        defaultConfig {
            ...
            multiDexEnabled true
            minSdkVersion **MINSDKVERSION**
            targetSdkVersion **TARGETSDKVERSION**
            ...
        }
    }

2.Prompt that the gradle version does not match.

Manually download the required gralde version compressed package and decompress it, and set the gradle directory in Untiy IDE.

3. Manifest attribute merge error.

After some SDKs are adapted to Android 11, the <queries> attribute will be added to the Manifest file. Android Gradle plugin 4.1 and higher are compatible with the new <queries> declaration; however, lower versions are not compatible. If you add the <queries> element or start to rely on libraries or SDKs that support Android 11 as the target platform, you may encounter manifest merge errors when building your app.

Solution: Upgrade the gradle plugin version, https://developer.android.com/studio/releases/gradle-plugin#4-0-0

Example : Modify file /Applications/Unity/Hub/Editor/2019.4.8f1/PaybackEngines/AndroidPlayer/Tools/GradleTemplate/baseProjectTemplate.gradle

 dependencies {
    classpath 'com.android.tools.build:gradle:3.4.3'
    **BUILD_SCRIPT_DEPS**
}
