Unity 与 Android (Android Studio)的交互

http://blog.csdn.net/kuerjinjin/article/details/50177633

1.大体思路：

在Android Studio 中编译导出Jar库，提供函数供 Unity 调用;安卓端提供三个测试函数：弹出对话框，弹出Toast，手机振动;Unity端提供界面，添加三个按钮分别调用这三个安卓提供的函数

2.编译环境

Unity 4.3.4 + Android Studio 1.5( buildToolVersion:23.0.2)

3.Android 部分

1）新建工程

新建一个 Android 工程例如叫 JarDemo ，然后依次点击：菜单栏中File -> New -> New Module -> 选择 Android Library -> 库的名称为 android2u3d，然后把layout下的activity_main.xml删掉，目前不需要这个布局文件。同时在MainActivity.java 的 onCreate 函数中将 setContentView(R.layout.activity_main); 删掉。

2）修改配置

在Unity4.x安装目录\Editor\Data\PlaybackEngines\androidplayer\bin 下找到classes.jar 文件拷贝到JarDemo\android2u3d\libs 目录下，然后依次点击菜单栏中File
-> Project Structures -> 在左侧栏的Modules下点击 android2u3d ，右侧选择 Dependencies 标签页，点击右侧的加号按钮，选择File Dependency，然后在弹出的对话框中选择libs下classes.jar；或者直接修改这个库对应的build.gradle文件，在dependencies节点下添加一行：

<code class="hljs livecodeserver has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">compile <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">files</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'libs/classes.jar'</span>)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

3）添加代码

现在开始需要修改 MainActivity.java 文件了，MainActivity需要继承自 UnityPlayerActivity

<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">MainActivity</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">UnityPlayerActivity</span> {</span>

关于手机的振动，需要修改AndroidManifest.xml文件添加权限的：

<code class="hljs xml has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"><<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">uses-permission</span> <span class="hljs-attribute" style="box-sizing: border-box; color: rgb(102, 0, 102);">android:name</span>=<span class="hljs-value" style="box-sizing: border-box; color: rgb(0, 136, 0);">"android.permission.VIBRATE"</span>></span><span class="hljs-tag" style="color: rgb(0, 102, 102); box-sizing: border-box;"></<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">uses-permission</span>></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

4）修改 build.gradle文件导出jar库

打开 build.gradle(Module:android2u3d) 在文件后面追加以下代码：

<code class="hljs livecodeserver has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">task makeJar(type: Copy) {

    <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">delete</span> <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'build/libs/android2u3d.jar'</span>

    <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">from</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'build/intermediates/bundles/release/'</span>)

    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">into</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'build/libs/'</span>)

    <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">include</span>(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'classes.jar'</span>)

    <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">rename</span> (<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'classes.jar'</span>, <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'android2u3d.jar'</span>)

}

makeJar.dependsOn(build)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li></ul>

然后在Terminal窗口中输入* gradlew makeJar* 来导出 android2u3d.jar;导出成功之后会有BUILD SUCCESSFUL 的提示！ jar导出成功之后的物理位置在 JarDemo\android2u3d\build\libs

TIPS:

A: 导出之前最好把不需要打包导出的东西统统干掉，比如 dependencies 下的

testCompile ‘junit:junit:4.12’

compile ‘com.android.support:appcompat-v7:23.1.0’

B: 以及Project -> Project -> JarDemo -> app -> src 下的 androidTest 和 test 这两个直接delect删掉。

C：第一次执行 gradlew makeJar 这个命令会下载一些东西不要关闭窗口，等他下载并配置完成之后再执行这个命令！

4.Uniy 部分

1)创建工程

新建一个Unity的工程如叫 JarDemo，在 Assets 下Create Folder 名称为 Plugins ，在这个文件夹下继续创建一个 Android，然后再次在Android 下创建一个文件夹 bin ;然后将上边生成的 android2u3d.jar 拷贝到这个Assets\Plugins\Android\bin 下，然后将安卓工程下JarDemo\android2u3d\src\main 中的AndroidManifest.xml 拷贝到 Assets\Plugins\Android目录下。

2）添加脚本

添加C#脚本名称如AndroidAPI，然后添加如下代码：

然后将这个 AndroidAPI.cs 拖动到 Main Camera 上进行绑定。

3）真机调试

需要先配置SDK，依次点击菜单栏Edit -> Preferences -> External Tools 在右侧下边的Android SDK Location 选择你的Android SDK所在目录。

4）构建设置

依次点击菜单栏 File -> Build Settings 在弹出的窗口中切换平台到 Android，右侧 Texture Compression选择 ETC1 or RGBA16(GLES 2.0)，同时勾选Development build和Autoconnect profiler这两个复选框。

点击Player Settings 在右侧的Inspector窗口下，常见的需要修改的 Bundle Identifier 等。

除此之外还需要修改下边那个Publishing Settings 中 keystore ，这里我们勾选 Create New KeyCode然后在keystore password 和 Confirm password 添加你设置的密码。

5）开始调试

OK,现在使用数据线连接安卓手机，允许调试后，点击Build And Run开始调试吧~
