Qt 5.4 declarative-camera example crashes on a Nexus 5 with Android 5.0 Lollipop



  • Hello,

    I've built the declarative-camera example bundled with Qt 5.4 for the kit "Android for armeabi-v7a (GCC 4.9, Qt 5.4.0)" selecting android-21 as Android Build SDK. Then I've deployed the example to my Nexus 5 running Android 5.0 Lollipop and it runs ok but when I try to select the "Front-Facing camera" using the pop-up button provided by the example application it crashes. I've included the Application Output from QtCreator below. Did anyone get the example running without this issue?
