How to easily batch convert many .svg files to Android Vector Drawables

Note that Android Studio claims to also be able to batch-import files starting version 3.4. Depending on how well that works and what you like, this solution might still be preferrable (it is for me)

We will need two tools:

1. Prior to conversion we want to optimize our .svg files using SVGO. SVG Optimizer is a Node.js-based tool for optimizing SVG vector graphics files. Find it here: https://www.npmjs.com/package/svgo

2. For conversion we will use vd-tool, a command line tool built from the actual converter inside Android Studio, so we know it will just do the same conversions. Here is a link: https://www.androiddesignpatterns.com/2018/11/android-studio-svg-to-vector-cli.html

How to find information from an installed Android app's SharedPreferences (if you have access to the keystore)

Prerequisite: Yes, you can gain some nice insights following this How-To, but you can only get to the end of it if you're legitimized to do so (you need to have the app's keyStore and the passwords to it!)

You should also have the Android Debug Bridge (adb) installed as well as Android Studio.

1. Install the app on your phone

You might want to use it a bit and play around with it so all the data you might be looking for in sharedPreferences gets generated.

2. Find the app's package name

Go to the Play Store website, search for your app, and open the app's page. Now you can just copy the package name from the address bar

Just check what sizing the fontScale is set to and change it to whatever we want. Then We have to reapply the configuration. This is an example method to put into an activity:

override fun attachBaseContext(newBase: Context?) {
        super.attachBaseContext(newBase)
        val conf = newBase!!.resources.configuration
        if (conf.fontScale > 1) {
            conf.fontScale = 1F
        applyOverrideConfiguration(conf)
