利用安卓系统Provider存储数据

1、需要添加权限

<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

2、设置数据

ContentResolver resolver = null;
resolver=getActivity().getContentResolver();
Settings.System.putString(resolver,Settings.System.GPS_PATH,pag);//键值对的形式存储

3、获取数据

Settings.System.getString(resolver, Settings.System.GPS_PATH);
