What about.abb

Hello! I've been reading Zenbit Tech blog for a couple of weeks now and thought I'd finally comment on one of their articles. I like the idea of creating an app to help protect data on AWS Architecture Areas using the encryption method—I think it would be a good fit for me because I'm a web developer and have experience working with Amazon Web Services (AWS). It would also be something that I could do with my current skills, so I don't have to take time away from my day job to learn new things.

Getting error with this "apt install default-jdk-headless openjdk-8-jdk-headless unzip aapt2"

Apt2 don't exist something

Same problem.

When I tried to follow with the instructions regardless, gradlew silently failed, claiming that the build completed successfully.

I get error: "/android-sdk/bin/java not found" when I run "gradlew", but the file is in /android-sdk/bin. I try chmod a+rwx, but it still doesn't work.

It's not an advertisement, I just want to help people, who doesn't have 64 bit system. Because i see, that some people couldn't create app with method in the top of the thread(of the page)

No such file or directory

Oh good but it requires a phone with substantial ram

In that case you can use CodeAssist, either the official one or the unofficial Deenu's CodeAssist. (This one recommended)
