How can i use onUpgrade Method?

Question

In my Android project, I put the table I created using DB Browser for SQlite into the assets folder. I can connect to the database and retrieve the necessary information. I would like to ask you to update the database on the computer and put it in the assets folder and update it with the onUpgrade metadata. How can I do that?

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
Log.d(LOG_TAG, " --- onUpgrade database from " + oldVersion
+ " to " + newVersion + " version --- ");
if (oldVersion == 1 && newVersion == 2)
{
this.getReadableDatabase();
try {
copyDataBase();
} catch (IOException e) {

throw new Error("Veritabany kopyalanamady");

}
}

The code didn't work for me.

Answer 1

if (oldVersion<newVersion){
    this.getReadableDatabase();
    try {
    copyDataBase();
    } catch (IOException e) {
        throw new Error("Veritabany kopyalanamady");
}
