I have an app that runs fine on my Galaxy S6 when it is installed via “ionic cordova run android” but when I install it using ionic cordova run android --prod, it shows the splash screen, then switches to an all white screen and just hangs there. I launched the Android monitor to see if any of the logging might help but nothing jumps out at me as being a problem. I was using Crosswalk and then thought perhaps there was an issue with that so I removed Crosswalk and deployed it again but with the same result. I’m fairly new to Ionic as this is my first Ionic app. Has anyone experienced an issue like this? Does anyone have any suggestions regarding how to troubleshoot this? Maybe logging that I might be unaware of, things to check, etc.? Right now I’m looking for a good starting point. Thank you in advance!

Thanks. The very interesting thing is that it appears to never launch the Webview because when I run it by installing from my machine, I get the option to inspect it. However, when I run from the installed version from the play store, it never gives me this option so it appears that it never launches the webview. At least that gets me closer to the actual problem even though I still have no idea what’s going on.

Release versions (built with --release) are not debuggable. That is why they don’t appear in the Chrome Inspect menu (which also makes it hard to debug these problems…)

Thanks. I was pretty sure that was the case. Do you know if it is possible to upload a debug version to the play store? I’m in the fortunate position of not yet having anyone other than beta users so I can play with this a little bit without impacting my user base.

I don’t think so. Which command did you use to build your debug builds you tested? Which command did you use to build the broken release build?

The debug build was: ionic cordova run android The release build used: ionic cordova build android --release --prod

Well, the “good” news is that when I do ionic cordova run android --prod it also fails as well. This means I can test various things without going through the play store. I can’t believe I didn’t think to try this from the get go. So, now to see what I can find out.

Yeah, the difference between --prod and --release is not very well documented (and these are also not very good names for the functionality behind it…)

Thanks for chiming in on this issue. I’ve basically decided to create a new project and drop piece by piece from my project into the new one until I break the new one so I can find the culprit. I will definitely update this thread when I have found my solution.
