Android Studio 打JAR包

在eclipse中我们知道如何将一个项目导出为jar包，供其它项目使用。
在AS中可以通过修改gradle才处理。
我们新建一个项目MakeJar，在项目中新建一个modle-类型为library
如图：

app为我们的主工程，librarydemo是我们要将其生成jar包的model.
在librarydemo中加入如下代码：

这里写图片描述

<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/mysdk.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;">'mysdk.jar'</span>)
}

makeJar.dependsOn(build)<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">
//在终端执行生成JAR包</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">
// gradlew makeJar</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><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><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li></ul>

在Terminal中键入 gradlew makeJar 回车看到如下所示就OK了：

输入命令 gadle makeJar

当然在主工程App的build中要加入librarydemo 这个依赖model：

<code class="hljs rust 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;">dependencies {
    compile fileTree(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">dir</span>: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'libs'</span>, include: [<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'*.jar'</span>])
    compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.android.support:appcompat-v7:22.2.0'</span>
    compile project(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">':librarydemo'</span>)
}</code>
