Android 监听彩信

测试机为 华为 8C，Android 版本 8.1.0。

<!-- 读短信权限 -->
<uses-permission android:name="android.permission.READ_SMS" />

动态申请权限代码此处略过。

注册监听：

MmsDatabaseChangeObserver mmsObserver = 
    new MmsDatabaseChangeObserver(getContentResolver(), new Handler(Looper.getMainLooper()));
getContentResolver().registerContentObserver(MMS_MESSAGE_URI, true, mmsObserver);

废话不多说，直接上代码：
