Problems with APK React-Native

Question

When I compile the project it generates the APK in the briefcase C:\Users<usuario>\Desktop\projetos\appTeste\android\app\build\outputs\apk.
If I catch the APK and put in a cell phone it installs right, but if I change something in the code, recompile and generate the new APK, as much as I delete the previous one and get the new one generated, when installing on the phone it installs the old version of the code.

For example:
I have a text written "Olá".
If I take the APK and install it on the phone, it installs and shows the text "Olá".
If I change the text to "Olá nova versão" recompile and pick up the new APK generated, it installs on mobile but still shows only the text "Olá", that would be the previous version of the project.

If I use one APK Signed, made the direct build by Android Studio also gives the same problem.

Answer 1

Try to "reset" the previous build and generate again, and change the code version as well, just as the above brother said
