怎么修改android手机apn的值

首先先得到当前的apn..对当前的APN进行判断

String resultApn = getCurrentAPNFromSetting(getContentResolver());
?????if (!resultApn.equals("")) {
??????if (!resultApn.equals("cmwap")) {
???????int apnCode = updateCurrentAPN(
?????????getContentResolver(), "cmwap");
??????}

}

然后在修改APN为你想要的模式,apnCode的值为1则修改成功！本地测试通过...
/**
? * 得到当前的apn
? *
? * @param resolver
? * @return
? */
?public static String getCurrentAPNFromSetting(ContentResolver resolver) {
??Cursor cursor = null;
??try {
???cursor = resolver.query(CURRENT_APN_URI, null, null, null, null);
???String curApnId = null;
???if (cursor != null && cursor.moveToFirst()) {
????curApnId = cursor.getString(cursor.getColumnIndex("_id"));
????String apnName1 = cursor
??????.getString(cursor.getColumnIndex("apn"));
???}
???cursor.close();
???// find apn name from apn list
???if (curApnId != null) {
????cursor = resolver.query(APN_LIST_URI, null, " _id = ?",
??????new String[] { curApnId }, null);
????if (cursor != null && cursor.moveToFirst()) {
?????String apnName = cursor.getString(cursor
???????.getColumnIndex("apn"));
?????return apnName;
????}
???}

??} catch (SQLException e) {
??} finally {
???if (cursor != null) {
????cursor.close();
???}
??}

??return null;
?}
