注意要给Activity加入以下权限：<uses-permission android:name="android.permission.PERMISSION_NAME" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
