1、com.baidu.mapapi.map.MapView (Open Class, Show Exception, Clear Cache)
The following classes could not be instantiated:
- com.baidu.mapapi.map.MapView (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE
java.lang.IllegalStateException: you have not supplyed the global app context info from SDKInitializer.initialize(Context) function.

官方Demo中也有此问题，没有影响使用，可忽略。
2、调用SDKInitializer.initialize(this)运行异常，程序闪退
经过多次折腾发现是权限问题造成。要确保权限信息是直接放在
<manifest></manifest>中的，不要放到其它元素中，在调试时没有错误提示，不容易发现，在发布时会提示错误。
<manifest ……> 省略……
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" /> <uses-permission android:name="android.permission.WAKE_LOCK"/> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.GET_TASKS" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_SETTINGS" />
</manifest>
３、发布后的百度地图应用中只显示网格，不显示地图图层
出现此问题一般是key认证错误造成的。
还记得最开始申请的百度地图key吗？当时是通过“keytool -list -v -keystore debug.keystore”申请的，是debug.keystore对应的SHA1申请的key；
而发布生成签名的apk时是不是用的另外的密钥文件？这个密钥文件跟debug.keystore的SHA1值是不同的，所以我们要通过“keytool -list -v -keystore key.store.jks”获取签名的密钥文件的SHA1值，重新申请百度地图key。
