Restore support for Qt 6.6.3 and Android 7.1 #12457
Conversation
Restored support for Qt 6.6.3 while preserving the existing build configuration for the primary supported Qt version (6.8.2). Changed the min. Android SDK version to 25 when the Qt version supports it. This allows targeting Android 7.1-based GCS such as the CubePilot Herelink or the SkyDroid H16. Key changes: - Lowered the QGC_QT_MINIMUM_VERSION CMake variable to 6.6.3, the latest Qt version compatible with Android 7.1. - Disabled the CMake features introduced in Qt versions 6.7 and 6.8 when configuring the project for Qt 6.6.3. - Updated build.gradle to utilize qtGradlePluginType only when available. - Reintroduced the "package" attribute in AndroidManifest.xml, which is necessary for Qt 6.6.3 but non-disruptive for the main supported version.

Not sure if you're interested in merging this, and my guess is that probably not, but it restores support for popular Android GCS like the Herelink and the SkyDroid H16. My hope is that 5.0 can be compatible with them out of the box, without messy patches. |

Yeah I think it's fine until we have to start checking Qt versions in the code all over the place. But we aren't using anything introduced in Qt6.8 yet, except for maybe QtMultimedia related stuff |
|
For my current version of Herelink I just downgraded the min sdk version and still use 6.8: https://github.com/DonLakeFlyer/Herelink-QGC/blob/master/custom/cmake/CustomOverrides.cmake Why not do that instead? |
|
But looking at the CMake and the GitHub workflows you're using Qt 6.6.3, no? Or am I missing something? AFAIK Qt 6.8 just doesn't support Android SDK 25. |
|
Sorry, I'm confused as to where we ended up. I can't remember the driver to move from 6.6.3 to 6.8. I think because 6.8 was LTS maybe? But LTS doesn't help us that much since open source doesn't get LTS updates anyway? In general I'd rather pick a Qt version and use that for everything. Is there good reason to move to 6.8 from 6.6? |
|
I recall one reason was supporting Arm based desktop builds |
|
Hmm, yeah. Useful. Maybe I'm overreacting to supporting multiple Qt. In reality the downgrade is just for things like Herelink/Skydroid. If it works it works. How about if we only allowed downgrade for android builds and messaged usage for Herelink/Skydroid situations? That limits exposure on desktop. |
