本文介绍了一个Android应用程序示例，展示了如何通过编程方式添加新的APN设置并将其设为默认APN。涉及的操作包括向系统数据库插入新记录及更新默认APN。

public class APNActivity extends Activity {

/***
* 是手机中获取所有APN的uri
* 列出全部的APN
*/
    public static final Uri APN_URI = Uri.parse("content://telephony/carriers");
    /***
     * 是手机默认调用的APN的URI
     * 获取当前使用的APN
    */
    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 _3gWapId = addAPN();
            SetAPN(_3gWapId);
    }

    //新增一个3GWap接入点
    public int addAPN() {
            int id = -1;
            ContentResolver resolver = this.getContentResolver();
            ContentValues values = new ContentValues();
            values.put("name", "3gwap");
            values.put("apn", "3gwap");
            values.put("mcc", "460");
            values.put("mnc", "01");
            values.put("numeric", "46001");

            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);
    }
