Ich habe meine apps mit dem folgenden Bash-Skript optimiert, welches die Bild- & Sound-Dateien komprimiert, so dass die Apps kleiner werden und weniger Speicher verbrauchen… :-)
Habe die optimierten Apps zu meinem Update-Pack für Spica hinzugefügt -> cyanogenmod + x
1.) Bash-Skript in einer Textdatei unter Linux speichern (Tweak_app.sh) & Ausführrechte setzen (chmod +x Tweak_app.sh)
2.) “optipng”, “pngcrush”, “sox” installieren (z.B. für Debian: apt-get install optipng pngcrush sox)
3.) android-sdk herunterladen & sudo cp …..android-sdk/android-sdk/zipalign /usr/bin/
4.) Folgendes Verzeichnis anlegen und zu optimierende Apps darin speichern (./place-apk-here-to-batch-optimize/)
5.) Tweak-Skript ausführen (./Tweak_app.sh) -> Fertig
