I use this code to copy my sqlite database from "Assets" directory to Android-phone "/data/data/my_packname/databases/" directory.
public class DataBaseHelper extends SQLiteOpenHelper{
private SQLiteDatabase myDataBase;
private final Context myContext;
public DataBaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
this.myContext = context;
}
...
private void copyDataBase() throws IOException{
//Open your local db as the input stream
AssetManager am = this.myContext.getAssets();
InputStream myInput = am.open(DATABASE_NAME);
// Path to the just created empty db
String outFileName = DATABASE_PATH + DATABASE_NAME;
//Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);
//transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer)) > 0){
myOutput.write(buffer, 0, length);
}
//Close the streams
myOutput.flush();
myOutput.close();
myInput.close();
}
...
}
But in line
while ((length = myInput.read(buffer)) > 0){
i have IOException!
Can anyone tell me what i'm doing wrong?
