Automating a native app using Appium/Selendroid

[Vincent Airiau]

Hi,
I'm currently trying to automate a simple youtube navigation using Appium. I got it working for 4.2+ android devices, but can't get it to for a Samsung Galaxy S2 under 4.0.4.
Selendroid is properly launched but I have this error when tryin to open the session: "[Selendroid] Error: Could not find app apk at 'undefined'"

Here are the capabilities passed to the session:
automationName: 'Selendroid'
platformName: 'Android'
deviceName: 'Samsung Galaxy S2'
appActivity: '.HomeActivity'
appPackage: 'com.google.android.youtube'

From what I would understand, it seems that Selendroid doesn't work by default with native apps. Is there a way to switch to a native context using Robotframework-appium?

Thank you

Hi,

 

Youtube is pre-installed on the device, correct? 

I guess the problem is that selendroid tries to install the apk before the tests (check the appium server logs, you should be able to see what appium/selendroid is trying to do before it fails)

 

a couple of ideas to try with:

1) browse through the appium documentation and look for "*reset*" caps (e.g. noReset, fullReset etc.)

The Appium documentation is pretty confusing about. As far as I can remember the documentation does not differentiate between pre-installed (i.e. no apk available) and self-developed (i.e. apk available) = it's pretty difficult to figure out what happens in which scenario --> try different combinations of the relevant caps 

 

2)

download the apk from your device and let seledroid (re)install before automating it.

 

cheerio,

Jari

Hi Jari and thank you for your answer.

I played around a bit with the reset caps but it didn't seem to have an effect on selendroid, it's still looks like it's searching for an apk to install in each case.
You are right in saying that the Appium doc isn't very talkative on this subject, apart from saying to check out Selendroid doc.

When passing the 'app' cap, Selendroid retrieves the value (as the 'aut' cap I guess). My guess is that appium might not have included native context in its way to use selendroid (or that it's waiting for a value that is not described in the doc).

I might just end up working with an apk and save me the trouble...

Alright so, after some search it seems to me that Selendroid does not support already installed apps like Appium does. I tried to pull the youtube app and let selendroid reinstall it but it does not have the proper permission to do it.
