无法使用编译软件开发工具包'android-Q'安装apk

Question

>"我试图安装我的apk，但它给出了这条消息。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。在直接从安卓工作室运行该应用程序时，它正在运行，但在生成 apk 后它没有安装？

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'
        }
    }
}
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.wdullaer:materialdatetimepicker:4.2.0'

    implementation 'com.google.android.gms:play-services-location:16.0.0'
}

要全面测试您的应用与 Android Q 的兼容性并开始使用新的 API，请打开模块级build.gradle文件并更新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
