To simulate migration database or trigger onUpgrade() on DevHelper in GreenDao,
the step will be:
1. Use simulate update app like in Google Play Store
Follow this : http://www.yodiaditya.com/android-simulate-update-application-google-play-store/
2. ALWAYS UPDATE SCHEMA VERSION GREENDAO
yes, i put this capitalized because it’s very important!
For instance:
1 2 3 4 5 | greendao { schemaVersion 5 daoPackage "YOUR_PACKAGE_NAME_AND_PATH.dao" } |
3. Always use SQLiteDatabase db to Trigger onUpgrade()
For instance:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 | /** * Created by Growth on 2016/3/3. */ public class DevOpenHelper extends DaoMaster.OpenHelper { Context mContext; public DevOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory) { super(context, name, factory); mContext = context; } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Timber.tag("HELO").d("DATABASE UPGREDE…………."); Timber.tag("HELO").d("GREENDAO upgrading schema from version " + oldVersion + " to " + newVersion + " by dropping all tables"); StandardDatabase dba = new StandardDatabase(db); if (newVersion > oldVersion) { switch (oldVersion) { case 1: DaoMaster.dropAllTables(dba, true); DaoMaster.createAllTables(dba, false); break; default: DaoMaster.dropAllTables(dba, true); DaoMaster.createAllTables(dba, false); } } } } |
Try to debug with logcat to see if onUpgrade executed
