我的问题是我将版本号附加到APK。更改版本号和重新同步Gradle为我解决了这个问题。

def appendVersionNameVersionCode(variant, defaultConfig) {
    variant.outputs.each { output ->
        if (output.zipAlign) {
            def file = output.outputFile
            def removeApp = file.name.replace("app-", "")
            def removeType = removeApp.replace("-release", "")
            def fileName = removeType.replace(".apk", "." + defaultConfig.versionName + ".apk")
            output.outputFile = new File(file.parent, fileName)
        }

        def file = output.packageApplication.outputFile
        def removeApp = file.name.replace("app-", "")
        def removeType = removeApp.replace("-release", "")
        def fileName = removeType.replace(".apk", "." + defaultConfig.versionName + ".apk")
        output.packageApplication.outputFile = new File(file.parent, fileName)
    }
}

当我切换git分支时，我经常看到类似的问题。对我来说，关闭AndroidStudio rm -rfv ~/Library/Caches/AndroidStudio*并重新启动AndroidStudio是门票。

构建APK(s)，并确保它工作

确保在路径中没有撇号或&

    1) This problem occure due to apk file .if your apk file
        (output/apk/debug.apk) not generated in this format . 

    2) you should use always in gradle file .

    buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }

对于Unix类用户(Linux/MacOs X)，而不是删除~/。Gradle /caches/，在命令行执行:

$ cd path_to_you_project
$ touch build.gradle

然后要求Android Studio构建APK，它将重置gradle缓存本身。
