Why Android APK much larger when installed? -

-

i installing apk weighs 2mb. once application installed weighs 9mb. there logical explanation this?

the apk file-format compressed format.

as install app android decompresses app because performs optimizations. reason unfavourable decompress before every start performance , battery-life reasons.

some apks bring native libraries them (for example many games or apps build delphi) stored uncompressed. escpecially kind of apps suffer being enormous large when installed compared java-only apps.
