Apk editor

Question

Hello to all , I have a question about apk editor software... Why when I want install modified apk file , the apk file can't be installed

Answer 1

Have you tried to sign the modified apk?
Maybe this comes also from the .dex files as they should interact with specific files so the modified files doesn't match the requirements.
I recommend to sign the apk with a default mode or with a custom sign

Answer 2

probably because of said modifications. there's not usually a one click solution to things like that, but if you can find one you'd be a LUCKY person

Answer 3

If you’re looking to tweak an Android APK, the safe, legit way is: decompile → edit → rebuild → re-sign. For basic resource/strings/icon changes, try an on-device tool like APK File Editor / APK Editor (such as: mt-manager.net ) for deeper work, use APKTool (smali/resources) plus Jadx (to read Java/Kotlin) on desktop, then rebuild, run zipalign, and re-sign with apksigner (you’ll need a new key, and Play updates won’t apply after resigning). Keep edits minimal, bump versionCode, and test on a spare device/VM. Avoid editing apps you don’t own or bypassing licensing—stick to personal/testing use or apps you have rights to modify.
