如何在“Android Studio”中为Android应用程序创建APK文件

Question

（Mac OS X 10.9.5，Android Studio 1.1 Preview 1） 我下载了this app.

它（某种程度上）是一个gradle项目。 我改变了一些事情。现在，我想创建AKP。

手册说：

  

  

1. 在Android Studio中打开项目

  

2. 打开配置文件/app/src/main/java/com/robotemplates/webviewapp/WebViewAppConfig.java   并根据需要设置常量（更多信息见下文）

  

3. 打开主构建脚本/app/build.gradle并根据需要设置常量（有关详细信息，请参见下文）

  

4. 在控制台中运行gradlew assemble

  

5. APK应该在/ app / build / outputs / apk目录中可用

  

1）我做了。

2）我做到了。在那里，我有：

    package com.company.app_name;

    public class WebViewAppConfig {
        // true for enabling debug logs, should be false in production release
        public static final boolean LOGS = false;

        // true for enabling Google Analytics, should be true in production release
        public static final boolean ANALYTICS = true;

        // true for enabling Google AdMob, should be true in production release
        public static final boolean ADMOB = true;

        // true for opening webview links in external web browser rather than directly in the webview
        public static final boolean OPEN_LINKS_IN_EXTERNAL_BROWSER = false;

        // list of file extensions for download,
        // if webview URL ends with this extension, that file will be downloaded via download manager,
        // keep this array empty if you do not want to use download manager
        public static final String[] DOWNLOAD_FILE_TYPES = {
                ".zip", ".rar", ".pdf", ".doc", ".xls",
                ".mp3", ".wma", ".ogg", ".m4a", ".wav",
                ".avi", ".mov", ".mp4", ".mpg", ".3gp"
        };
    }

3）我有：

        // Main build script for WebView App
        // 
        // Usage: gradlew assembleDebug           Build debug APK
        //        gradlew assembleRelease         Build production APK
        //        gradle wrapper                  Create Gradle Wrapper


        final VERSION_MAJOR = 1 // max two digits
        final VERSION_MINOR = 2 // max two digits
        final VERSION_PATCH = 0 // max two digits
        final VERSION_BUILD = 0 // max three digits


        apply plugin: 'com.android.application'


        dependencies
        {
            compile 'com.android.support:support-v4:20.+'

        }

                    storeFile file("../${project.property('keystore.file')}")

                                {

4）当我跑步时，＃gradlew assemble＆＃34;在终端，它说：没有找到评论。 为什么？什么是错？请帮帮我！
