Mobile and Embedded

Made a completely fresh install. The same error is still shown in the options, but my Android builds seem to be working now. Marking as solved for now.

@TripleF Awesome, this works! Thank you

I found that QtAndroid setting permissions on the external SD card did not work, so I used java, but the first time I put the file in the root directory, it also prompted the file to have no permissions until I saw this https://stackoverflow. com/questions/43349110/android-write-on-external-sd-card-java-io-ioexception-permission-denied found the new folder path, and then I tried it and it can be used

Did you install the plugin packages like suggested in the error message ?

@AlexKrammer said in How to put the object creation from the cpp into the h without getting an error.: So in this fault the float is exactly 1000; In that fault the float is exactly 999. so I don't see any reason not to compare. Otherwise I understand that you don't compare a float with something Then I'm afraid you have not understood how floating point numbers work on computers and what the potential problem in your code is. I suggested you use qFuzzyCompare() and gave the link, there is a reason it is provided. The catch() stuff has nothing to do with explaining how/whether it works. It is just very odd to mix exception types.

@Jose-LZ said in The mess of the Android tools: The documentation in https://doc.qt.io/qt-5/android-getting-started.html is only a list of thinks but does not explain what each element is. You are more than welcome to contribute additions/clarifications to such document so others users could benefit from your experience :-)

@glamis said in Qt5 with OpenGL (on Raspberry Pi 0) getting error QXcbConnection: Could not connect to display Could not connect to any X display: did indeed work great, please don't forget to mark your post as solved!

Hi, re. deployment of your mobile app thru WiFi (not cable) from Qt Creator: it's not working but I think it's an upcoming feature. But there are 3rd party apps out there that can help push your app bundle to your iphone across WiFi, I use one called ios-deploy You should be able to install it using homebrew inside your VM: brew install ios-deploy To deploy, first check that the iPhone is up and running on your network: ios-deploy -c [....] Waiting up to 5 seconds for iOS device to be connected [....] Found a02328a4bc16005421432a3071eb5bcacd25a6a23a (D211AP, iPhone 8 Plus, iphoneos, arm64) a.k.a. 'HenrysPhone' connected through WIFI. Then navigate to your build folder and deploy to the phone, example: cd /Users/henry/Projects/build-untitled-Qt_5_15_0_for_iOS-Release/Release-iphoneos ios-deploy --bundle untitled.app [....] Waiting for iOS device to be connected [....] Using a02328a4bc16005421432a3071eb5bcacd25a6a23a (D211AP, iPhone 8 Plus, iphoneos, arm64) a.k.a.
