Android:设置APN为cmnet源码

public class APNActivity extends Activity {

        public static final Uri APN_URI = Uri.parse("content://telephony/carriers");
        public static final Uri CURRENT_APN_URI = Uri.parse("content://telephony/carriers/preferapn");

        @Override
        public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);
                int _cmnetId = addAPN();
                SetAPN(_cmnetId);
        }
       public void checkAPN(){
      // 检查当前连接的APN
              Cursor cr = getContentResolver().query(CURRENT_APN_URI, null, null,
              null, null);
              while (cr != null && cr.moveToNext()) {
                  // APN id
                  String id = cr.getString(cr.getColumnIndex("_id"));
                  // APN name
                  String apn = StringUtils.null2String(cr
                  .getString(cr.getColumnIndex("apn")));
                  // Toast.makeText(getApplicationContext(),
                  // "当前 id:" + id + " apn:" + apn, Toast.LENGTH_LONG).show();

       }

        //新增一个cmnet接入点
        public int addAPN() {
                int id = -1;
                ContentResolver resolver = this.getContentResolver();
                ContentValues values = new ContentValues();
                values.put("name", "cmnet");
                values.put("apn", "cmnet");
                Cursor c = null;
                Uri newRow = resolver.insert(APN_URI, values);
                if (newRow != null) {
                        c = resolver.query(newRow, null, null, null, null);
                        int idIndex = c.getColumnIndex("_id");
                        c.moveToFirst();
                        id = c.getShort(idIndex);
                }
                if (c != null)
                        c.close();
                return id;
        }
        //设置接入点
        public void SetAPN(int id) {
                ContentResolver resolver = this.getContentResolver();
                ContentValues values = new ContentValues();
                values.put("apn_id", id);
                resolver.update(CURRENT_APN_URI, values, null, null);
