What language does android use?

Question

I want to be able to modify the android source code. Will the app teach me to do that?

Answer 1

Android Studio is aiming to be a Kotlin first. Otherwise, it's Java.

As to "modify the Android source code", do you mean from another app?
That's against the terms and conditions of almost (if not all) every app.
Sololearn doesn't teach such things.

Answer 2

If you want to unlock your phone, there are various options available. You can check with your carrier if they can unlock your phone, especially if you have been a customer for a year or more. Alternatively, you could purchase an unlocked phone from your provider. Another option is to use a third-party unlocking service or buy an already unlocked phone from a retailer. There are also jailbreaking apps, but since the legality of jailbreaking a phone can vary depending on the country or region where you are located, I am unable to provide further information.

Answer 3

Well I have a galaxy a14 5g but it is through metro. They have a superuser program in place that doesn't allow OEM unlock. So I am unable to root my phone. I have tried everything and I am not able to root this phone. I read androids terms and conditions and it stipulates that the coding is allowed to be changed to modify system files. Other than that I am researching the electronics and iot side of things and want to be able to code my own devices.
