Android external database in assets folder

Question

I have an android application that is supposed to read and expand a database that is already created on sqlite...it works fine on emulator by putting database in \"data/data

Answer 1

you cant access the database from asset folder directly you need to copy it first to the path data/data/(packagename)/database then using it :

 private String DB_PATH = "/data/data/" + "yourpackaename" + "/databases/" + "db.db";

in your onCreate()

 is = getAssets().open("db.db");
 write(is);

Then the method to call:

public void write(InputStream is) {
    try {
        OutputStream out = new FileOutputStream(new File(DB_PATH));
        int read = 0;
        byte[] bytes = new byte[1024];

        while ((read = is.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        is.close();
        out.flush();
        out.close();
        System.err.println(out + "\n");
    } catch (IOException e) {
        e.printStackTrace();
    }
}
