Include torified android calendar app.

Either

• make the Calendar app directly connect to Nextcloud on tor.
• make Caldav app connect to tor, and make calendar app read caldav app
• Make Nextcloud app connect to tor server.

This is exactly what the orbot app does.

To download the app from f-droid one:

1. First installs the f-droid apk from f-droid.org.
2. Next, in that f-droid app on the phone, one can go to: settings> (My Apps)> Repositories> (Enable) Guardian Project Official Releases.
3. (Update the repositories with: `back> Updates> pull the window down to do an update of the repositories).
4. Next, search in the market place search for: orbot and select the one that literally says: Orbot: Tor for Android. If that is not in there, verify you enabled the Guardian Project Official Releases and that you updated the fdroid market place/repositories.
5. Install the Orbot app.
6. Open the Orbot app.
7. Enable "VPN Mode"
8. Select "tor enabled apps" and choose which app you want to go over tor.
9. Back in the main Orbot screen/window, press/hold "start" until you see a green onion.
10. Now you can go to your app, e.g. Nextcloud and enter your https://some_onion.onion domain, to make the Nextcloud connect to your self-hosted Nextcloud server.

This is marvellous work by the Guardian Project I think. I am amazed by how well it works, and have not automated this yet through adb.

For orbot, adding the nextcloud app resulted in adding the line:

    <string name="PrefTord">com.nextcloud.client|</string>

Alternative to adb to automate some stuff on phone (monkeyrunner): https://developer.android.com/studio/test/monkeyrunner

Example:

# Imports the monkeyrunner modules used by this program.
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice

# Connects to the current device, returning a MonkeyDevice object.
device = MonkeyRunner.waitForConnection()

# Installs the Android package. Notice that this method returns a boolean, so you can test
# whether the installation worked.
device.installPackage('myproject/bin/MyApplication.apk')

# Sets a variable with the package's internal name.
package = 'com.example.android.myapplication'

# Sets a variable with the name of an Activity in the package.
activity = 'com.example.android.myapplication.MainActivity'

# Sets the name of the component to start.
runComponent = package + '/' + activity

# Runs the component.
device.startActivity(component=runComponent)

# Presses the Menu button.
device.press('KEYCODE_MENU', MonkeyDevice.DOWN_AND_UP)

# Takes a screenshot.
result = device.takeSnapshot()

# Writes the screenshot to a file.
result.writeToFile('myproject/shot1.png','png')

Done, Orbot torifies DAVx5. Both are installed and configured automatically.
