I've decided that I'll be using Room. My issue is that what if every time each activity accesses the database it creates a separate database and all the information are found in different databases. The user's profile activity can use the first 4 tables and that 1 table that shows something the user can be, a second activity that shows the other 5 tables, and the last 3 tables can be accessed from the conversation activity. (Let me know if this is incorrect as I am new to. or the: update (String table, ContentValues values, String whereClause, String whereArgs) method. From what Ive read and tried, you can just use the: execSQL (String sql) method. After searching for ways to do that, I found that it is best to use WorkManager to do the necessary threading (I have never done threading so any help or tutorial is appreciated).Ĥ of them are directly related to the user (the user's personal information), 5 are linked to some activity the user performed, 1 can be related to something else the user can be (it's not mandatory), and the last 3 are linked to the conversation that the user has. Ive been trying to update a specific row for a while now, and it seems that there are two ways to do this. The android studio tutorial on SQLite recommends that I set up a background thread to call getWritableDatabase()) or getReadableDatabase()). In my app all the tables (13 in total) are in the same database. Now you have the SQLite database file and you can open it in a SQLite browser of your choice, e.g. Material Design Icons Weekly Threads Calendar Device File Explorer in Android Studio 3.0. ![]() For news and questions about these topics try using other subs likeĪndroid Job Interview Questions and Answers This sub-reddit isn't about phones' and apps' general functionality, support, or system software development (ROMs). Check the latest benchmark results out yourself and draw your own conclusions.News for Android app developers with the who, what, where, when, and how of the Android community. All our benchmarks are open source for maximum transparency while trying to meet high standards. While there are things that make us proud, we’re no particular fans of marketing speech. We want to provide the fastest Android ORM. We’re regularly doing benchmarks to optimize performance, because we believe performance matters. Is greenDAO really that fast? Is it the fastest Android ORM? Have a look at current statistics for yourself at AppBrain. We think, this shows industry proven reliability. Several of those apps have over 10 million installs. How to get started with greenDAO, Documentationįor first steps with greenDAO, please check the documentation, especially the getting started guide and the introduction tutorial. You want to learn more about greenDAO features like active entities, protocol buffers support, or eager loading? Then have a look at our full feature list. Strong community: More than 5.000 GitHub stars show there is a strong and active community.Database encryption: greenDAO supports SQLCipher to keep your user’s data safe.Small library size (Easy to use powerful APIs covering relations and joins.Maximum performance (probably the fastest ORM for Android) our benchmarks are open sourced too.This way you can store, update, delete, and query for Java objects using a simple object oriented API. ![]() greenDAO frees you from these by mapping Java objects to database tables (called ORM, “object/relational mapping”). Still, writing SQL and parsing query results are quite tedious and time-consuming tasks. SQLite is an awesome embedded relational database. It relieves developers from dealing with low-level database requirements while saving development time. GreenDAO is an open source Android ORM making development for SQLite databases fun again. For existing apps based on greenDAO we offer DaoCompat for an easy switch (see also the announcement). Note: for new apps we recommend ObjectBox, a new object-oriented database that is much faster than SQLite and easier to use. ![]()
