### 34.2. Install Android apps

I don’t know how to download files from the web on Vanilla android, the default browser does not download anything, and there is no `wget`:

Installing with `adb install` does however work: https://stackoverflow.com/questions/7076240/install-an-apk-file-from-command-prompt

F-Droid installed fine like that, however it does not have permission to install apps: https://www.maketecheasier.com/install-apps-from-unknown-sources-android/

And the `Settings` app crashes so I can’t change it, logcat contains:

    No service published for: wifip2p

which is mentioned at: https://stackoverflow.com/questions/47839955/android-8-settings-app-crashes-on-emulator-with-clean-aosp-build

We also tried to enable it from the command line with:

    settings put secure install_non_market_apps 1

as mentioned at: https://android.stackexchange.com/questions/77280/allow-unknown-sources-from-terminal-without-going-to-settings-app but it didn’t work either.

No person alive seems to know how to pre-install apps on AOSP: https://stackoverflow.com/questions/6249458/pre-installing-android-application

Tested on: `8.1.0_r60`.
