<p>resConfigs “en”, “de”, “fr”, “it”<br>resConfigs “nodpi”, “hdpi”, “xhdpi”, “xxhdpi”, “xxxhdpi”<br>}</p>
<p>保留指定资源目录，去除库项目可能存在的冗余资源</p>
<p>shrinkResources 使用注意项目是否存在反射获取资源</p>
<h3 id="6-_Java_SDK_版本建议用_7_支持_Android_API_Level_8_及以上">6. Java SDK 版本建议用 7 支持 Android API Level 8 及以上</h3>
<p>compileOptions {<br>sourceCompatibility JavaVersion.VERSION_1_7<br>targetCompatibility JavaVersion.VERSION_1_7<br>}</p>
<p>Added support for Java 7 language features like multi-catch, try-with-resources, and the diamond operator.</p>
<p>Try-with-resources requires minSdkVersion 19; the rest of the new language features require minSdkVersion 8 or higher.</p>
<p>项目规模较小可以考虑采用 JDK 8，lambda 有助于代码简洁，配合 Rxjava 是极好的</p>
<p>使用见 <a href="https://github.com/evant/gradle-retrolambda" target="_blank" rel="external">https://github.com/evant/gradle-retrolambda</a></p>
<p>Android Studio 对 lambda 的支持也是极好的</p>

<p><code>Android Studio</code>的项目中自带了<code>gradle</code> 编译环境，如下图：<br><img src="http://ww4.sinaimg.cn/mw690/72589a09gw1emysp5vs01j20fp0d0dgq.jpg" alt=""></p>
<p><code>gradle wrapper</code> 避免了<code>gradle</code> 因版本不同引发的种种问题，使你不用在本地安装<code>gradle</code> 就可以执行编译命令。</p>
<ol>
<li><p><code>server:CardViewSample samzhao$ ./gradlew clean assemble</code></p>
<p>先清理以前编译过的文件再编译，耗时最长。我这次编译用了</p>
<p><code>BUILD SUCCESSFUL</code></p>
<p><code>Total time: 32.394 secs</code></p>
</li>
<li><p><code>server:CardViewSample samzhao$ ./gradlew assemble</code></p>
<p>不清理，采用以前编译好的，不需要重新编译的文件进行编译。许多编译项目后面都跟有<code>UP-TO-DATE</code>，如：<br><code>:app:compileDebugAidl UP-TO-DATE</code><br>这主要是更新了文件的时间戳，没有进行重新编译。这次时间明显减少了：</p>
<p><code>BUILD SUCCESSFUL</code></p>
<p><code>Total time: 8.394 secs</code></p>
</li>
<li><p><code>server:CardViewSample samzhao$ ./gradlew assemble --daemon</code></p>
<p>加上<code>--daemon</code>后缀就不用每次编译时都把<code>gradle</code>重新加载到内存了，第一次用<code>--daemon</code>，编译时间还是8秒多，但第二次运行就快很多了，如下：</p>
<p><code>BUILD SUCCESSFUL</code></p>
<p><code>Total time: 4.021 secs</code></p>
</li>
</ol>
<p>编译好的apk在如下位置：</p>
<p><img src="http://ww3.sinaimg.cn/mw690/72589a09gw1emytzr9qjmj20yy0d5q5m.jpg" alt=""></p>
<p><strong>其实<code>clean</code>和<code>assemble</code>都是<code>gradle</code>的<code>task</code></strong></p>
