Android app doesn't run

[ekkescorner]

@JKSH said in Android app doesn't run:

Be warned, that manifest editor is badly broken: https://bugreports.qt.io/browse/QTCREATORBUG-27119 I recommend that you don't touch it -- even the act of opening that editor is enough to corrupt the manifest file in some cases.

also have noticed that opening with Manifest Editor sometimes changes the content. But in my cases it was only a reformatting / reordering and nothing destroyed. (QtC 12.0.1)

BTW: I'm getting best experiences this way:

• Update Templates
• check changes (using git)
• add / replace with my settings
  this way I'm always getting the newest recommended values

Could you elaborate on this? Changes to what, exactly?

[ekkescorner]

@mzimmers see here what I did while updating from 5.15 to 6.6:

this will give you the idea how I'm doing this

[mzimmers]

@JKSH thanks for the warning about the manifest editor -- it looks like TQC has painted itself into a corner on this one.

I was going to try your suggestion, but now I have a different problem: my Android device shows as "disconnected" and I can't figure out what to do about this.

[mzimmers]

@ekkescorner that's a great page. I'm using 6.5.3; do you think your suggestions will work with this version?

[ekkescorner]

@mzimmers will be similar, but not the same. per ex. the Qt FileProvider only exists in 6.6+

@mzimmers said in Android app doesn't run:

connected via wifi or via usb cable ?

[JoeCFD]

@mzimmers Click Manage Kits->Devices
select your device in Device combobox since your device may not be the default one.
Then click Debug above Run button and select your connected device.

[mzimmers]

@ekkescorner USB cable. I deleted that device, and am trying to create a new one, but it keeps trying to make an emulator, not a "real" Android device.

[ekkescorner]

@mzimmers creating devices is for emulators. to connect via USB see https://t1p.de/ekkeManageDevices

[mzimmers]

@JoeCFD interesting -- I thought I had deleted that device, but it still shows up (and appears to be selected):

I'm not sure what you are referring to with "Debug above Run button." I'm only trying to build a release version.

[mzimmers]

@ekkescorner oh, OK. I didn't realize that.

So...any idea why my device is showing as disconnected?

[JoeCFD]

@mzimmers click Devices and show the tabs. I am debugging my app for Android now and have debug build. If you are building release, then it is Release above Run button on the lower left corner of Qt Creator.

@JoeCFD

[JoeCFD]

@mzimmers is this device correct? Click the down arrow and you can see more.
If yes, check if the cable is on. I had this issue this morning. The cable was off.

[mzimmers]

@JoeCFD it's the same device that worked for me last year. And it's indeed connected (I think it would have to be if it's auto-detected).

[JoeCFD]

@mzimmers Go to your computer and click this device to see if you are able to browse inside this device. For example, copy a file from this device to your computer. If yes, this means the device is connected to your computer. Otherwise, it is not connected.

[mzimmers]

@JoeCFD tried that, and it sure appears to be connected:

I'm starting to wonder if there's something wrong with the SDK that Creator downloaded for me.

[JoeCFD]

@mzimmers yes, it is connected. Click the Android tab to see if anything is not set properly. I am now working with a Galaxy Tab A as well and do not have issues. Do you need to enable debugging in your Tablet? I remember you set it.

[mzimmers]

@JoeCFD bingo. Now my device shows as ready to use.

Unfortunately, I'm now back to my original error:

Activity Manager threw the error: Error type 3
Error: Activity class {org.qtproject.example.weatherinfo/org.qtproject.qt.android.bindings.QtActivity} does not exist.

And, to @JKSH's suggestion, this is without modifying any of the files in my android directory.

How do these settings compare with yours?
