“我试图安装我的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。

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'
        }
    }

    implementation 'com.wdullaer:materialdatetimepicker:4.2.0'

    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

    implementation 'com.google.android.gms:play-services-maps:16.1.0'
    implementation 'com.google.android.gms:play-services-location:16.0.0'
}

最佳答案

要完全测试您的应用程序与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compileSdkVersion and targetSdkVersion,如下所示

android {
    compileSdkVersion 29

    defaultConfig {
        targetSdkVersion 29
    }

}


费耶

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
