I am exploring the source code of an App. There is SQLiteDatabase used in the source code.
import android.database.Cursor;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.database.sqlite.SQLiteDatabase;
public class MainActivity extends AppCompatActivity {
private SQLiteDatabase db;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
I put the source code in my IntelliJ and Android Studio IDEs, but both of them cannot recognize this class. The import android.database.sqlite.SQLiteDatabase
is also shown in grey color. I am totally new for writing Apps, is there anything to set up to use this class?
