Configuring

Create AVD (Android Virtual Device)

C:\Users\<Username>\necessitas\android-sdk-windows\ SDK-Manager.exe
A popup dialog appears which refreshes the available devices. Ignore it or cancel.
NEVER DO Update and install : to get other virtual devices. Stick to the ones Necessitas provides.

On the left you have a selection list.
Installed packages
It shows you about 8 entries with different versions of Android SDK platforms.
Virtual devices
Here you create your AVD
Click the button new. Give it a name e.g. Android2.3.3. Choose a target e.g. Android 2.3.3 – API level 10. Size : 1024 mb. Snapshot enabled. Skin : HVGA
Press the button Create AVD and the name you choose appears in the list.

Android Qt Creator settings

You only have to set the path to ant.bat. The other fields are filled in automatically.
You can see your AVD target you made earlier.

Compiling

Debug version

In Qt Creator select the build …Arm v 5 Debug and start using the green arrow bug button “Start debugging” or F5. This will make the libYOURPROGRAMNAME.so which you will need later for the next step. It is possible that Qt Creator cannot get through, but that’s no problem. The most important is you have the .so file.

3

Build version

The next step is to choose for build …Arm v 5 Release.

4

On Tab Manifest

choose for Android 10

On Tab Permissions

android.permission.INTERNET
android.permission.WRITE_EXTERNAL_STORAGE

On Tab Libraries

Click the button “Read information from application (must be compiled)”
This will read the necessary libraries like libqtCore.so.
You don’t have to click the libraries, even if the checkboxes are not checked it will work…

Check the option : “Install Ministro system wide qt shared libraries installer” and click the button “Choose apk” to point to the Ministro-2.0.apk file you installed earlier.

Click Run or CTRL + R
Then you see your app icon, it launches and wants to download files (only the first time).
Your app will start automatically now.

Have fun!
