Download apk editor software

Open the software, find the application APK file we want to modify in the editor, press and hold it on the APK file, and then select "Make * * * Save" in the pop-up menu.

After selecting "Make * * * Save", we need to find an output directory for the newly generated * * * Save application, give it a new name, and then click OK. After waiting for a few seconds, two softwares will be generated and successfully completed.
