ContentProvider not called onCreate after deleting database

Question

I have created ContentProvider which creates one Database on application launching.

Now In that application, I am doing process of deleting database when user logout from app.

After that when I come again to login, the ContentProvider cant call onCreate() of overrided class.

Is there any way to recreate database using ContentProvider?

You do something strange... database should not work in such way. Who delete whole database on user logout? If there are some specific data related only to the login - then delete the data only. Just clear the temporary tables... its way better then delete whole database on every user logout and recreate it on every user login :) – Alfi

I found solution as,

First of all I referred Refresh/Reload database reference in custom ContentProvider after restore but not satisfied with answer because its just for closing database.

So I have created my answer as below:

DBHelper.java

/**
 * Delete database
 */
public static void reCreateDatabase(Context mContext) {
    ContentResolver resolver = mContext.getContentResolver();
    ContentProviderClient client = resolver.acquireContentProviderClient(KOOPSContentProvider.AUTHORITY);

    assert client != null;
    KOOPSContentProvider provider = (KOOPSContentProvider) client.getLocalContentProvider();

    assert provider != null;
    provider.resetDatabase();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)
        client.close();
    else
        client.release();

    LOGD("Database Deleted...");
}

public void removeDatabase(Context mContext) {
    mContext.deleteDatabase(DATABASE_NAME);
    LOGD("Database Deleted...");
}

KOOPSContentProvider.java

public void resetDatabase() {
    if(dbHelper != null) {
        dbHelper.removeDatabase(getContext());
        dbHelper = new DbHelper(getContext());
    } else {
        LOGD("Database NULL");
    }
}

USE As:

DbHelper.reCreateDatabase(mContext);

Thank you :) :)
