Android Question App not installing on Android 5.0 Lollipop

[aaronk]

Hi,

Anyone else finding that there app does not install on Android 5.0 Lollipop (The latest release) ?

I am finding that when I try and install the app on Android 5.0 Lollipop (using the B4A IDE) it comes up saying if I want to install the app, so I tap on Install then a few seconds later it says 'App not installed'.

I then try and install the same app on my Android 4.4.4 device and it works fine (using the B4A IDE).

Anyone else had the same issue and does anyone have any ideas on where I should start looking ?

Which device are you using for this test?
Are you able to install with USB debug mode?

I am using a Nexus 5, with Android 5.0 Lollipop and it for some reason fails.
I then have a Sony Xperia Z running Android 4.4.4 KitKat and it installs fine.

I did have the developer preview (Android L) on my Nexus 5 and it installed fine.

I wonder if this has something with the new SDK I downloaded. However I did replace the AAPT file which allowed me to now compile the app, just won't install now.

When I try and compile it using the USB I get the following error:

Restarting ADB Server may solve this problem.
Tools - Restart ADB Server. Device serial: 074ae88d0074fe59

I have gone to 'Tools' > 'Restart ADB Server' then tried to compile the app again, then a popup messages comes up on my device saying if I allow USB debugging. I tapped on OK, and then got the same error as above.

Try to uninstall the current installed app (assuming there is one) and then install again.

then got the same error as above
Failure [INSTALL_FAILED_VERSION_DOWNGRADE]

It seems that the version already installed on device has an NEWER versioncode than the app you want to install. The new installation needs the same or a newer versioncode to be installed.

Try uninstall the app from device manually. then install ist again. It should now work.
Probably the handling of versions of an app has changed in Lollipops releaseversion and B4A need an update. It´s just a thought...

I thought I didn't have it installed but looks like I did have it installed.

Just uninstalled the app and now its working. All but the SSL socket since Google hasn't fixed the bug

 

[Erel]

Now try to install it again and see whether it works or not (maybe there is a problem with installation of an app with the same version).

 

[aaronk]

Yeah its working now. Except the SSL Socket won't connect.
Normal sockets work fine though.

I posted this 'wish' a while back but it will be really, really good if someone can get the wolf SSL lib working with B4A.

Happy to pay someone (around $500-$600) to get it working with B4A. (that's how despite I am for SSL sockets to work with B4A)
