Externally generated SQLite database considered read-only by Android's SQLiteOpenHelper

Question

I have an SQLite database that I have generated using the SQLite JDBC connector found here.

I have then copied this database to my Android phone\'s SD card, and atte

Answer 1

Sqlite will only open databases from your applications database directory.

DB_PATH = "/data/data/"+ context.getPackageName() + "/databases/"; 

In order to read and write your database, my understanding is that you will need to copy your database to this location:

InputStream myInput = myContext.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();

In order to do this copy, you will first have to open a database at the eventual destination of your database file:

checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);
