Build a QML program to create the APK file and warnings

tomy · wrote on 24 Dec 2018, 16:44

Hi,

After finishing the preliminary version of a QML app, I went for building its APK file. Hence, on Qt Creator 4.8.0, I tapped the Build bottom for the Arm7, Debug mode, kit.

Below is the outcome of the Compile Output window. As it's shown, there are five lines in red as warnings.
My questions are:

1- Is it a normal way of creating the APK file for Android devices to test the program?
2- Have I done the work correctly?
3- I see no difference in size of either Release or Debug mode for the above app, is it ordinary?
4- I think the APK file for testing on Android devices must be in the Release mode of the Arm7 kit. It it right?

Looks like you are system was not setup. Hence it will download all the necessary things. This will not happen every time. After all this did creator deploy the application on android mobile ?

Hi, thanks for the reply.
No, it's not working well on Android devices. What is the problem please?

Did you do the setup for Android with instruction at WIKI. When you connect the Android device to your laptop, is it recognised in Qt Creator ?

@dheerendra
I don't have an Android device. So I just Build the program on the Android Arm7 kit in the Debug mode and then copy the created .apk file and send that to friends who have Android phones to test it.

Here's my the details for the files on my PC:

Bye the way, the result of testing the application (a simple ping pong game) was as below. Shown half! :(

While it's shown well when run by the Desktop kit on Windows:

What could be the problem please?

This indicates that you are able to build the APK & install on the Android device. It could be size of issue of top level object. Can you check what is the size(width, height) of top level item in your example.

@dheerendra

The top level item on the program is the window and it starts this way:

Window {
    id: window
    visible: true
    visibility: Window.Maximized
    title: qsTr("The PingPong Game - A QML Game")
    color: "gray"
 ...

Is there something incorrect with this please?
