Unity2019.2.x 导出apk 安装到安卓Android12+及以上的系统版本 安装出现-108 安装包似乎无效的解决办法

导出AndroidStudio工程后 需要设置

build.gradle文件

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0' //最低这个
}
}

allprojects {
    repositories {
        google()
        jcenter()
        flatDir {
            dirs 'libs'
        }
    }
}

apply plugin: 'com.android.application'


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
}

android {
    compileSdkVersion 34   //必须这个
    buildToolsVersion '30.0.2' //可选这个

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 34 //必须这个
        applicationId 'com.hemiao.mycabin'
        ndk {
            abiFilters 'armeabi-v7a', 'arm64-v8a'
        }
        versionCode 1
        versionName '1.0'
    }

    lintOptions {
        abortOnError false
    }

    aaptOptions {
        noCompress = ['.unity3d', '.ress', '.resource', '.obb']
        ignoreAssetsPattern = "!.svn:!.git:!.ds_store:!*.scc:.*:!CVS:!thumbs.db:!picasa.ini:!*~"
    }

    signingConfigs {
        release {
            storeFile file('D:/svn-MyCabin/接GooglePay/myCabin.keystore')
            storePassword '123456'
            keyAlias 'mycabin'
            keyPassword '123456'
        }
    }

    buildTypes {
        debug {
            minifyEnabled false
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
            signingConfig signingConfigs.release
            jniDebuggable true
        }
        release {
            minifyEnabled false
            useProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-unity.txt'
            signingConfig signingConfigs.release
        }
    }

    packagingOptions {
        doNotStrip '*/armeabi-v7a/*.so'
        doNotStrip '*/arm64-v8a/*.so'
    }


    bundle {
        language {
            enableSplit = false
        }
        density {
            enableSplit = false
        }
        abi {
            enableSplit = true
        }
    }
}

如果要上gp的话 还要 设置AndroidManifest.xml  增加字段android:exported="true"

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.hemiao.mycabin" xmlns:tools="http://schemas.android.com/tools" android:installLocation="preferExternal">

配上Proejct Setting., 注target Api 要34
