Using SQLite in android demo

1.in android,you can using SQLite save data,as flowing exampe:

package tuo.test;

import tuo.test.entity.UserProfile;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class GucSQLite extends SQLiteOpenHelper {

	private static final String DATABASE_NAME = "GucNightingale.db";
	private static final String TABLE_NAME = "nurse_app_setting";
	private static final int DATABASE_VERSION = 1;

	String TAG = "GucSQLite";

	public GucSQLite(Context context) {
		super(context, DATABASE_NAME, null, DATABASE_VERSION);
	}

	@Override
	public void onCreate(SQLiteDatabase database) {
		String creat_sql = "CREATE TABLE "
				+ TABLE_NAME
				+ " (id INTEGER PRIMARY KEY AUTOINCREMENT,mobile TEXT,appid TEXT,pwd TEXT,dept TEXT,his_account TEXT)";
		database.execSQL(creat_sql);
	}

	@Override
	public void onUpgrade(SQLiteDatabase database, int oldVersion,
			int newVersion) {
		database.execSQL("DROP TABLE IF EXISTS" + TABLE_NAME);
		onCreate(database);
	}

	public UserProfile getUserProfile() {
		UserProfile userProfile = null;
		SQLiteDatabase db = this.getReadableDatabase();
		Cursor cursor = db.query(TABLE_NAME, new String[] { "id", "appid","mobile", "pwd", "dept", "his_account" }, null, null, null,null, null);
		while (cursor.moveToNext()) {
			userProfile = new UserProfile();
			userProfile.setId(cursor.getString(0));
			userProfile.setAppid(cursor.getString(1));
			userProfile.setMobile(cursor.getString(2));
			userProfile.setPwd(cursor.getString(3));
			userProfile.setDept(cursor.getString(4));
			userProfile.setHis_account(cursor.getString(5));
		}
		return userProfile;
	}

	public boolean saveOrUpdateUserProfile(UserProfile user) {
		int result;
		ContentValues values = new ContentValues();
		values.put("appid", user.getAppid());
		values.put("mobile", user.getMobile());
		values.put("pwd", user.getPwd());
		values.put("dept", user.getDept());
		values.put("his_account", user.getHis_account());
		if (isExist(user)) {
			String whereClause = "mobile =?";
			String[] whereArgs = new String[] { user.getMobile() };
			result = (int) this.getWritableDatabase().update(TABLE_NAME,values, whereClause, whereArgs);
		} else {
			result = (int) this.getWritableDatabase().insertOrThrow(TABLE_NAME,null, values);
		}
		return result > 0;
	}

	private boolean isExist(UserProfile user) {
		return this.getReadableDatabase()
				   .rawQuery("SELECT id FROM " + TABLE_NAME + " WHERE mobile="+ user.getMobile(), null).getCount() > 0;
	}

}
