Accelbubble example

jan0385

Hello,

I'm trying the "accelbubble" example to get working. Before that I successfully ran the Hello World Example created with the QtCteator. I'm using my mobile not the emulator

But trying to run the accelbubble example I'm getting the following error message:

Do you know how to solve the problem? Please notice the "QtSensors" plugin "declarative_sensors" error.

Hi!

I had the same problem and I fixed it by making these changes in the QML file:

@import QtSensors 5.0 as Sensors
...
Sensors.Accelerometer {
....
}

Hi,

When I switch from Realease to Debug mode this "module 'QtSensors' plugin 'declarative_sensors' not found"-error is away and the app runs.

But untfortunatelly I dont understand why. Can you tell me?

In Debug mode I can see this in the Compiler output:

In Release mode I dont see that. The names of these libraries match exactly to those entries I added to the .pro file:

QT += quick sensors svg xml

tks for your post.But what's the real reason?
