android將sqlite數據庫與程序一起發布

 把數據庫文件放在res/raw下 貌似android 的raw下視不會被編譯成二進制的。然后一運行程序就判斷是否存在數據庫表不存在則通過輸入輸出流復制raw下的數據庫文件到手機中.代碼如下

try {


Log.e(DATABASE_PATH, DATABASE_PATH);
String databaseFilename = DATABASE_PATH + "/" + DATABASE_FILENAME;
File dir = new File(DATABASE_PATH);

if (!dir.exists())
    dir.mkdir();

if (!(new File(databaseFilename)).exists()) {

    InputStream is = getResources().openRawResource(
            R.raw.healthmanage);
    FileOutputStream fos = new FileOutputStream(databaseFilename);
    byte[] buffer = new byte[8192];
    int count = 0;

    while ((count = is.read(buffer)) > 0) {
        fos.write(buffer, 0, count);
    }

    fos.close();
    is.close();
}


} catch (Exception e) {
    Log.e("出錯了", "出錯了");
}</pre>
