I followed the istruction to export an APK from four different video and the official Godot Dokumentation but when i open the APK on my phone, i have to accept the security warning, then it's loading with the text ,,Istalling..." and then there is the text ,,App not installed", and i only can klick on Okay.
Its very fustrading because i am trying to fix it since 4 Days and no one can help me, i reinstalled Godot, Android Studio and Java foure time and tryed everything again, but again ,,App not installed"
Pleas can someone help me.
Here is the Exported APK which can not be installed if anyone can do something with it:

Can't download without permission.

    I could install it, but I get this error:

    The Godot docs say:
    If you get an error saying "Could not install to device.", make sure you do not have an application with the same Android package name already installed on the device (but signed with a different _key).

    If you have an application with the same Android package name but a different signing key already installed on the device, you must remove the application in question from the Android device before exporting to Android again._

      trizZzle I don't think i have a other application with the same Android package name installed on my Phone, because thats my first project i (tryed) to export

        Strange, sorry, I have no idea what the issue is. 😐

          trizZzle Yea thats my issue, i asked in Discord, i asked in GitHub and now here. I searched thrue the internet for a few hours, no one knows why i have this error

            I don't know if this will help you but I had a similar issue the other day. Have you set up your Unique Name and Name in Export settings for Android?

            If you have the default values for those properties it's possible you already have an app with that unique name in your phone (from previous tests, maybe?) and that is conflicting with your new test. Also. check that you don't have any apps in your phone that were generated by Godot (whenever you do a test in your phone, an app is installed).

              Anthuulos Yea i have a unique name, and i change it every time i export it, exactly because of that. I also tryed it right now on my dads phone, it also showed the error ,,App not installed"

                I'd create a new blank project and try to export and install it, just to check if it's specific to this one project or if it happens with all of them...

                  housatic i am doing this the whole time, i am exporting an empty project. And right now i tryed installing Godot, Java and Android Studio on a other PC but also the error ,,App not installed". I'm starting to think about going back to Unity if it doesn't work for Godot because there you just have to click one fucking button, i tryed EVERYTHYNG now.
                  I Reinstalled everything several times, i followed different tutorials (inc. the Official Documantation from Godot), i tryed installing it on another phone, i tryed exporting it on another PC. This shit is driving me crazy!!!!!!!

                      Stonie Weird :-( I'm guessing you reported this on Github already? Did you try installing some older versions of Godot, see if it happens there too?

                          Stonie Have you tried it on a different phone? On my phone it was working. Maybe your phone is the issue?

                              trizZzle I thought you couldn't install it either, because you also got an error

                                  housatic yea i reported it, but they closed the report, because it is not Bug Report for the Godot Engine

                                    Stonie I could install it, but there was no main scene defined in the project. So the game shut down again. See screenshot I posted 2 days ago.

                                        trizZzle Which APK did you install, the one in my Google Drive? Because i tryed installing it on my phone and my dad's phone, both with the same error ,,App not installed"

                                            trizZzle I really don't know what to do now, some say they can't install the APK, some say they can. I have tried it on several phones with the same error.
