android - Qt Android输出APK在〜/android-build\build\outputs\apk\debug中生成

Question

问题:我想在Qt项目中使用Android构建系统(版本3)，但是此gradle版本(与旧版本2相比)会将生成的输出apk文件的位置更改为$buildDir/outputs/apk/debug之下，而不是$buildDir/outputs/apk(添加了debug)文件夹)，但是当Qt Android套件尝试将应用安装到Android设备时，它只会在旧位置显示，而无法找到apk文件。我检查了Android Studio及其它是否表明Gradle 3正常工作
旧位置:$build_folder/android-build\build\outputs\apk\my.apk新位置:$build_folder/android-build\build\outputs\apk\debug\my.apk
错误(编译):

adb: error: cannot stat 'D:/Qt/FireBase/build-client01-Android_for_armeabi_v7a_GCC_4_9_Qt_5_11_0_for_Android_armv73-Release/android-build//build/outputs/apk/android-build-debug.apk': No such file or directory

仅当我对Qt生成的默认 build.gradle进行更改以将gradle设置为版本3时，才会发生此问题，默认生成的文件将 classpath设置为旧版本 2.3.3，
旧: classpath 'com.android.tools.build:gradle:2.3.3'新增: classpath 'com.android.tools.build:gradle:3.1.0
我还有其他更改，也需要更改 gradle-wrapper.properties，这是更新的文件:

build.gradle

buildscript {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }

    dependencies {
        //classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'com.google.gms:google-services:4.0.1' // google-services plugin
        classpath 'com.android.tools.build:gradle:3.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
        //google() // Google's Maven repository
        maven {
            url "https://maven.google.com"
        }
    }
}

apply plugin: 'com.android.application'


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

}

android {
    /*******************************************************

    compileSdkVersion androidCompileSdkVersion.toInteger()

    buildToolsVersion androidBuildToolsVersion

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = [qt5AndroidDir + '/src', 'src', 'java']
            aidl.srcDirs = [qt5AndroidDir + '/src', 'src', 'aidl']

       }
    }

        abortOnError false
    }
}

Answer 1

我在build.gradle上使用它:

android {
...
    applicationVariants.all { variant ->
        variant.outputs.all {
            outputFileName = "../" + outputFileName
        }
    }
}
