 # ComPactMultiDex
-针对MultiDex的补充优化、支持多线程加载多dex包、支持多进程dexopt、支持解压抽取dex时可以不进行zip压缩
+针对MultiDex的补充优化、支持多线程加载多dex包、支持多进程dexopt、支持解压抽取dex时可以不进行zip压缩等优化选项，针对4.4及以下在首次启动的时候要进行除主dex的dex提取、dex提取压缩，crc以及dexopt等一系列耗时操作的优化补充库。
+
+### 接入步骤
+
+1. build.gradle配置
+```
+
+```
+
+2. 查看路径下buid/intermediates/legacy_multidex_main_dex_list/release/mainDexList.txt, 若没有ComPactMultiDex相关的类，则加入下面的类，主要是为了确保主dex有包含到
+```

+com/gibbon/compactmultidex/ConcurrentMultiDexExtractor$ZipEntryGroup.class
+com/gibbon/compactmultidex/ConcurrentMultiDexExtractor$ZipEntryWrapper.class
+com/gibbon/compactmultidex/ConcurrentMultiDexExtractor.class

+```
+
+3. 添加application，或者直接使用MultiDexApplication
+
+```
+public class DemoApplication extends Application {
+    @Override
+    protected void attachBaseContext(Context base) {
+        super.attachBaseContext(base);
+        // install方法可以加入需要的优化选项
+        MultiDex.install(this，？);
+    }
+}
+```
+或AndroidManifest.xml文件中修改application如下
+```
+<application
+        android:name=".MultiDexApplication"
+        android:allowBackup="true"
+        android:icon="@mipmap/ic_launcher"
+        android:label="@string/app_name"
+        android:roundIcon="@mipmap/ic_launcher_round"
+        android:supportsRtl="true"
+        android:theme="@style/AppTheme">
+        
+    </application>
+```
