从资产Android复制SQLite数据库不适用于KitKat 4.4

Question

I red different question here on StackOverflow but mine is a little bit newer.

All of these don't work: Question1 Question2 Question3

I updated my devices to Android KitKat 4.4 and when I try to copy database with this code:

private void copyDataBase() throws IOException {
    InputStream myInput = context.getAssets().open(DB_NAME);
    String outFileName = DB_PATH + DB_NAME;
    OutputStream myOutput = new FileOutputStream(outFileName);
    byte[] buffer = new byte[1024];
    int length;
    while ((length = myInput.read(buffer)) > 0) {
        myOutput.write(buffer, 0, length);
    }
    myOutput.flush();
    myOutput.close();
    myInput.close();
}

I obtain a FileNotFoundException at line:

OutputStream myOutput = new FileOutputStream(outFileName);

Someone fix this issue on Android KitKat??? (other platforms works great)

Thanks for help.

Answer 1

Full hardcoded

NEVER HARDCODE PATHS . Use getDatabasePath() to find the proper place for a database.

other platforms works great

It certainly will crash on Android 4.2+ tablets for secondary accounts. It may crash in other environments as well. NEVER HARDCODE PATHS .

Note that SQLiteAssetHelper uses getDatabasePath() .
