Fix android package name

example/android/app/src/main/AndroidManifest.xml

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
-    package="com.example">
+    package="cn.qiuxiang.react.amap3d.example">
 
     <uses-permission android:name="android.permission.INTERNET" />
     <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

example/android/app/src/main/java/com/example/MainActivity.java → example/android/app/src/main/java/cn/qiuxiang/react/amap3d/example/MainActivity.java

-package com.example;
+package cn.qiuxiang.react.amap3d.example;
 
 import com.facebook.react.ReactActivity;
 

example/android/app/src/main/java/com/example/MainApplication.java → example/android/app/src/main/java/cn/qiuxiang/react/amap3d/example/MainApplication.java

-package com.example;
+package cn.qiuxiang.react.amap3d.example;
 
 import android.app.Application;
