如何修改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;
 }
