Is it possible to install Android's .apk file?
The only way to run Android apps in Ubuntu (as far as I'm aware) is to install Android SDK, create a virtual Android device, use the SDK's tools to install the .apk file on that device and run the app inside the device.
Android developer portal has a lot of info on the subject.
Android packages, .apk files, are a completely different packaging format than Ubuntu's packaging format, .deb files.
Besides the packaging differences, Android packages are compiled and customized for the Android operating system, toolchain, and architecture (ARM), which is different from most Ubuntu systems which are 32-bit or 64-bit Intel architecture.
You can use the ARChon to run apk in ubuntu:
- Install the ARChon Runtime. http::github.com/vladikoff/chromeos-apk/blob/master/archon.md
- Open and enable the flag: chrome://flags/#enable-nacl,then restart Google-Chrome. (Important!)
- Install existing android apps in the website or convert your favourite android apps by "Online APK-CRX Converter.
- Drag and drop the Google-Chrome extensions into the chrome://extensions/ page in the browser and it will be installed in your browser. Enjor it!
