Solution to android.database.sqlite.sqliteexception code 5 database is locked

Class MyActivity extends Activity{
CommunicationWithDBCls communic=new CommunicationWithDBCls();

call(){

imgAsynTask = new ImageShowAsyncTask(this, imgUrlAryLi, count,
                    this, progress);
            imgAsynTask.execute();
}
}

And

// some stuff
}

@Override
    protected Bitmap doInBackground(Void… paramArrayOfParams) {

try{
//some stuff related to getting image from server n saving it to DB
}catch(Exception e){

}finally{
communic.close();
}

}

}

the correct Code is like this:

imgAsynTask = new ImageShowAsyncTask(this, imgUrlAryLi, count,
                    this, progress,communic);
            imgAsynTask.execute();
}
}

And

public class ImageShowAsyncTask extends AsyncTask<Void, String, Bitmap> {

CommunicationWithDBCls communic;
public ImageShowAsyncTask(CallBackInterFace callBackInterface,
            ArrayList<String> arryLisUrl, int count, Context cont,
            ProgressBar progress, CommunicationWithDBCls communic2) {

//some stuff
}

@Override
    protected Bitmap doInBackground(Void… paramArrayOfParams) {

try{
//some stuff related to getting image from server n saving it to DB
}catch(Exception e){

}

}

}
