Making an app with AI

In 2026 one sentence can start an Android app. You write what you want, and the tool returns a project. That is not an app ready for the store. It is a start.

There is still code inside. The code may be Kotlin. It may also be a page packed into an APK. Those are not the same thing. Packing a page is not learning a language. When you write your own screen and button, Java or Kotlin comes in.

A model can leave a button half done, a permission too wide, or text that is not in your language. Do not say it is ready before you open it on a real phone. An empty screen, a broken button, and a missing permission show up there.

Putting it in the store is a separate job. The name, the icon, the package name, and the signature stay with you. The package name does not change later. If the signature is lost, the update is lost too. AI does not cancel these rules.

• Ask for one screen first. "An app that has everything" brings an empty, mixed project.
• Open the project, press the button, go back. Do this on a phone, not only in a picture.
• Read the permission list. Remove the camera and the contacts if you do not need them.
• Let the package name look like com.ad.soz. Each part should start with a letter.
• Keep the signature. The same file is needed for an update on another computer.
• When installation stops, the cause is often the same: parse error, signature, or package name.
• The store can reject the app. A half screen and someone else's name are enough for that.

The APK errors are the same on this road: it will not install, parse error, signature, and package name.
