Out of the box hello world example does not run on Android



  • This out of the box example "hello world" works for native osx and ios simulator, but not in an Android x86 emulator. For Android, I'm using the lastest SDK with: android-ndk-r13b-darwin-x86_64.zip, and tools_r25.2.3-macosx.zip

    import QtQuick 2.7
    import QtQuick.Window 2.2
    
    Window {
        visible: true
        width: 640
        height: 480
        title: qsTr("Hello World")
    
        MainForm {
            anchors.fill: parent
            mouseArea.onClicked: {
                console.log(qsTr('Clicked on background. Text: "' + textEdit.text + '"'))
            }
        }
    }

    @gkraft4 said in Out of the box hello world example does not run on Android:

    D gralloc_ranchu: Emulator without host-side GPU emulation detected.

    That's your issue. Your host system doesn't have opengl set up or installed properly. Even on an on board intel gpu you should still be able to run this.

    Oh and just a side note, r14 is latest stable with r15 in beta right now. That doesn't matter just letting you know r13 isn't the latest any more. :)

    With HW graphics turned on in the emulator, I'm still getting similar "Shader compilation failed" errors.

  • One thing that troubles me is I have x86_64 libraries and emulator, but Qt Creator is targeting x86. It runs fine on my samsung s4 arm device.

    That beings up a good point. The ARM device is going to be 32-bit. So creator is targeting the right platform.

    My question here though is do you have the appropriately built ARM 32 Qt libs on your target device? If you just tried to load your desktop 64 bit Qt libs that will definitely not work.

    It's not just bit depth though, you will need cross compiler ARM 32-bit libs. Intel x86 or x86-64 libs (or AMD64) will not work.
