Qt Necessitas error - Can't find Ministro service

Question

I downloaded the Necessitas installer for Linux, but I can't make my "Hello World" Qt application run on the debugger's Android VM.

It gives this error:

Can't find Ministro service.
The application can't start.

And this is the Debug log from Qt Creator:

Starting remote process...D/dalvikvm( 2497): GC freed 699 objects / 55432 bytes in 152ms

So I can't run my program. It compiles otherwise. From what I've seen on the Internet, Ministro is a service for deploying the shared Qt libraries needed by Qt applications on Android.

So why am I getting this error (on a freshly installed Necessitas+empty Android project)? And what do I do to make my program run, do I need to manually install the Qt libs? From where?

Answer 1

If I remember correctly, you had to use the modified Qt creator that comes with Necessitas and the first time you wanted to deploy your application to Android device, you had to take the following steps:

1. On the left side of Qt Creator go to Projects
2. In the projects window in the run tab of Necessitas Qt for android you have to go to Deploy configurations and click to expand details
3. In details check Install Ministro system wide Qt shared libraries installer and select the APK you downloaded earlier (I think I got it from here http://necessitas.kde.org/necessitas/ministro.php)
4. Just build and run your program as normally

Let me know if the following steps worked for you. I think there is yet another way, which involves ADB and command line, but for that I would have to lookup my notes, which I currently do not have with me...
