Is it possible to remotely run queries to a database on a device through a web interface?

So far I think it's a security thing that you're not allowed reading/writing to an Android SQLite database outside of the containing app's process.

But are there advanced techniques or tools that can be used to achieve this?

For instance, I want to make a web interface with a textbox where the Android app would connect to and then I can run SQL queries via said interface to read the database or to insert records into it.

I'm writing this question because I'm really stumped. Usually my search gives opposite results which is accessing a remote database with an Android app.

Apps can read and write to their SQLite databases. Otherwise, the database would not exist.

You are certainly welcome to embed a Web server into your app. For example, Stetho does this to integrate with Chrome Dev Tools, offering your SQL interface among other things.

However:

  • Doing this for anything other than a debug build of your app is very risky, as securing a Web server is difficult enough when it is on a traditional server environment, let alone an Android device

  • The Web server is only accessible by whatever can reach the device via an IP address, which means it's usually only useful on WiFi (where it could be reached by other devices on the same WiFi LAN segment)

You will have to develop an API backend. The mobile app ( client ) will communicate with the API and do the desired operation based on the response.

It's not possible to directly connect to the app sqlite database. You can send web request and get the info you want, handle it in your app to store it in the sqlite database

You will have to add security measures, so everyone can't access your API.
