APK via Web Server download - SD Card corruption?

DEVELOPMENT TESTING

I’m distributing my .apk file via a web server download. My only Android tester made the following observations:

+++++++++++++++++

The app downloaded fine.

I opened it to install.

It said I had to disable a setting that says I should only download apps from Google Play.

Then I got to the page that said “Do you want to install this application?”

It said it could " Modify or delete the contents of your SD card" so I did not install it. 

If you can get rid of that I will try installing it.

+++++++++++++++++

I do not have an Android phone so cannot confirm the above - and am concerned about the red-highlighted warning above. Is this a generic warning thrown out at everything when an app is NOT from Google Play - or does it indicate something untoward that I’ve created within the app?

Thanks in advance for any suggestions/advice/comments.

That is a warning when apps are to be installed on devices, and are requesting the (I believe) " android.permission.WRITE_EXTERNAL_STORAGE" permission. It’s relatively normal for apps to request this so that, for instance, assets can be saved to other storage if necessary. 

While it sounds scary, it’s not really that big of a deal. I have a feeling your lone Android tester don’t download/play Android games that often, so perhaps they are wary of any warning that comes up. Alternatively, you could remove the above permission from your build.settings and see if it removes that warning.

Alex@Panc -

thank bunches for the advice (I commented out android.permission.WRITE_EXTERNAL_STORAGE). the install went forward and now I, too, can download to my Android Nexus10 device. Big step forward for my first business app!

My Android tester is not a “games” user.

Another change I effected simultaneously was to enter NONE for Target App Store when doing the build from Corona Simulator on Windows.

Now if the build/install process was as easy for Apple…
