When I run ionic cordova build android --prod --release command, it corrupts my release.apk file.
debug.apk file is 15MB, whereas release.apk file is 4.5MB
When I say corrupt, during time of installation it show App Not Installed however debug.apk file gets installed successfully.
Also, when I sign the debug.apk file with certificate using jarsigner and later do zipalign, it also corrupts debug.apk file bringing down file size to 4.5MB.
Not sure what is happening with --release flag
Above all is happening with manual signing. But when I tried the build process with Android Studio, I get the same result.
