4.4 OTA Release

[jonathan-k4]

I see that 4.4 was released about 3 weeks ago on this repo. However, I can't install it on my Herelink via ADB because the original 4.0.8 on there is part of the system apps. When will a system update be released for Herelink that includes the 4.4 version?

Thanks.

You should be able to sideload it using adb.

[jagould2012]

You can’t sideload it. You receive a [INSTALL_FAILED_VERSION_DOWNGRADE] error. You also can’t delete the factory loaded app, which I tried to maybe get past the adb error. Presumably this is because it was signed as a system app during the herelink image build?

[julianoes]

Ok, thanks for the info. I will have to look into this next week. Are you sure you don't have some release candidate version of it installed?

[jagould2012]

Current installed version is herelink-4.0.8 that came with the device. This is the first time I’ve tried to update.

[julianoes]

Ok, that's not ok then. I will look into this next week. I am confused because I have it side-loaded on my stock image with stock QGC 4.0.8.

[jonathan-k4]

Is it possible you built it when you side loaded and built it with a different bundleId? That would get around the issue, would just be two separate apps. I was using the prebuilt apk from the 4.4 release page, which matches the one on the device.

Let me know if there is any adb output I can provide that will help you track it down when you get to looking at it. Thanks.

I'm pretty sure I tested the artifact from here: https://github.com/CubePilot/qgroundcontrol-herelink/releases/tag/v4.4.0-herelink
I'll try it again and double check.

[julianoes]

Ok, for me v4.0.8 looks like this:

I then install v4.4.0 from releases using adb:

adb install QGroundControl-Herelink.apk

And I now have both versions installed:

Can you try to uninstall Herelink-QGroundControl first, and then try again?

And also paste a screenshot of the applications list?

Steps to reproduce:

• Downloaded apk from https://github.com/CubePilot/qgroundcontrol-herelink/releases/download/v4.4.0-herelink/QGroundControl-Herelink.apk

• adb install QGroundControl-Herelink.apk

Error:

adb: failed to install QGroundControl-Herelink.apk: Failure [INSTALL_FAILED_VERSION_DOWNGRADE]

• also attempted adb install -r QGroundControl-Herelink.apk

• pm list packages -f | grep mavlink lists

package:/system/app/QGroundControl/QGroundControl.apk=org.mavlink.qgroundcontrol

which as I understand it, because its installed as a system app, I cant delete it or overwrite without root?

Screenshot of app and trying to delete it:

Logcat output from when I try to delete:

07-12 09:22:29.678   744   772 W PackageManager: Attempt to delete unknown system package org.mavlink.qgroundcontrol

Some articles suggest disabling "verify apps over USB" to potentially force a way around this, but this option appears to have been disabled during the system image build:

[jonathan-k4]

Ok... success. I was able to force the uninstall the app as the root user (0) using this command:

pm uninstall -k --user 0 org.mavlink.qgroundcontrol

Then the install would work:

adb install QGroundControl-Herelink.apk

That said, would recommend in future versions of the system image build that you maybe not load and sign the app as a system app?

[julianoes]

Hang on, on your screenshot above I see two icons of QGC, so presumably you have two versions installed already? As far as my testing goes, the stock one does not need uninstalling.

[jonathan-k4]

The second want ones a stock QGroundControl image from Android store. FYI - I ended up having to remove both to get adb install to work.

[julianoes]

That said, would recommend in future versions of the system image build that you maybe not load and sign the app as a system app?

Yes, that was not the goal. I'm still struggling to find out why it works for me. Let me check the IDs:

pm list packages -f | grep qgr                                                                                                       
package:/data/app/org.mavlink.qgroundcontrolbeta-2/base.apk=org.mavlink.qgroundcontrolbeta
package:/system/app/QGroundControl/QGroundControl.apk=org.mavlink.qgroundcontrol

Now I uninstall v4.4.0.1 and check again:

pm list packages -f | grep qgr                                                                                                       
package:/system/app/QGroundControl/QGroundControl.apk=org.mavlink.qgroundcontrol

[julianoes]

Now I install it again.

pm list packages -f | grep qgr                                                                                                       
package:/data/app/org.mavlink.qgroundcontrolbeta-1/base.apk=org.mavlink.qgroundcontrolbeta
package:/system/app/QGroundControl/QGroundControl.apk=org.mavlink.qgroundcontrol

[julianoes]

The beta name is set here, presumably. I'm not 100% sure how this all works.

The second app on mine also had the org.mavlink.qgroundcontrolbeta package name, so it wasn't part of any of the commands I listed above. It was also installed in the data directory like yours (user space) so was easily removed. The preloaded one was installed in the system directory, and I had to do the pm uninstall -k --user 0 org.mavlink.qgroundcontrol to remove it.

Hope that helps.
