Deploying android applications Qt 5.1

 

I have been trying to deploy a simple Qt application to android but with no luck. Details are as follows

  • Qt Version : Qt 5.1.0 for Android (Windows 32-bit) downloaded from here

  • Qt Creator version : Qt Creator 2.7.2

    • I have set the following options in Qt Creator

    Android configurations

  • Android SDK location : C:adt-bundle-windows-x86-20130717adt-bundle-windows-x86-20130717sdk

  • Android NDK location : C:android-ndk-r8e

  • Ant location : C:Program FilesJavajdk1.7.0_25

  • AVD name : AndroidAVD (API Level 17,armeabi-v7a)

    • Kit Configuration

  • Name of the kit : Android for arm(GCC 4.4.3,Qt 5.1.0)(default)

  • Device type : Android

  • Device : Run on Android

  • Sysroot : Its empty

  • Compiler : GCC (arm 4.4.3 )

  • Android GDB Server : C:android-ndk-r8eprebuiltandroid-armgdbserver

  • Debugger : C:android-ndk-r8etoolchainsarm-linux-androideabi-4.4.3prebuiltwindowsbinarm-linux-androideabi-gdb.exe

  • Qt Version : 5.1.0 (android_armv7)(C:QtQt5.1.05.1.0android_armv7binqmake.exe)

  • Deploy configuration of the Kit(for both Release and Debug) : Deploy local Qt libraries and Use Local Qt libraries option is checked

  • OS : Windows 7 64 bit

    • The Problem

    When I try to build,everything builds fine. I get libTheTestApp.so in my build directory. Also the project directory now contains a folder named "android" containing the manifest file and some other files.

    When I try to Run the app, the emulator starts but I can't find my app. If I close my emulator and return to Qt Creator I get the following error

    Please wait, searching for a suitable device for target:android-17.
    Error while building/deploying project TheTestApp (kit: Android for arm (GCC 4.4.3, Qt 5.1.0)) When executing step 'Deploy to Android device'

    If I do "adb devices" while the emulator is running, I get the id of the running emulator

    Also I tried searching the internet before posting this question here. I found this link.

    My question is how do I deploy a Qt5 application to an android device? Are there any links which say how to do it? I am asking this because I have followed the instructions provided in Qt5ForAndroidBuilding link while building the app.

    Thanks for your time.

    I was successfully able to deploy a simple QT application to my android device. From what I understand ,Qt creator first tries to deploy the app to a device if it finds one. If no device is found, it tries to launch an AVD and deploys the application to the emulator.

    "Please wait, searching for a suitable device for target:android-17." Try targeting a lower api level by changing it in Projects->Selected Toolkit -> Run -> Package Configuartion -> Manifest

    And also , make sure that the Ant location points to InstallLocationantbinant.bat

  • You did not mention that whether you specified jdk location in Qt Creator or not.
  • for ant location, please specify the path to bin/ant.bat file from ant directory.

    • For people who will see this post in the future:

    Do not launch avd from Qt Creator, first run the avd from android sdk manager

  • do not create your own avd, use the existing ones instead, as follows
  • go to android sdk folder, open android SDK Manager > tools > Manage AVDs...
  • there are two tabs at the top, go to "Device Definition" tab
  • select any one avd and click on "Create AVD"
  • from new window that comes up, select target api level, cpu/abi and check snapshot checkBox at the bottom of the window and press "ok" button.
  • new window comes up with the specifications of created avd, click ok now you have a valid avd. Select it and press "start" button. wait until the avd is lauched, unlock it and run you project.
