”“我尝试安装我的apk，但它给出了此消息。程序包似乎已损坏。这是我的build.gradle文件。”但是，当我将compilesdkversion更改为28时，它正在运行。直接从android studio运行该应用程序时，它正在运行，但是生成apk后没有安装？

apply plugin: 'com.android.application'

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    compileSdkVersion 'android-Q'
    defaultConfig {
        applicationId "com.example.deskneedui"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

要完全测试您的应用与Android Q的兼容性并开始使用新的API，请打开您的 模块级 build.gradle文件，并更新< strong> compileSdkVersion and targetSdkVersion ，如下所示

android {
    compileSdkVersion 29

    defaultConfig {
        targetSdkVersion 29
    }

}

仅供参考

您的 classpath 将是

 classpath 'com.android.tools.build:gradle:3.4.1'

distributionUrl 将是

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

无法通过CompileSDKVersion'android-Q'安装APK
