Switching from Qt 5.1 to Qt 5.2 is causing app to crash



  • I recently downloaded Qt 5.2 and I loaded my working app from Qt 5.1 into it and it keeps crashing because it says that it is calling “startRecording()” on an uninitiated AudioRecord. Here is the error when the initialization fails
    @E/AudioRecord(14313): AudioFlinger could not create record track, status: -1
    E/AudioRecord-JNI(14313): Error creating AudioRecord instance: initialization check failed.
    E/AudioRecord-Java(14313): [ android.media.AudioRecord ] Error code -20 when initializing native AudioRecord object.@

    Here is the error where an exception is thrown causing the program to crash
    @E/AndroidRuntime(14313): FATAL EXCEPTION: Thread-855
    E/AndroidRuntime(14313): java.lang.IllegalStateException: startRecording() called on an uninitialized AudioRecord.
    E/AndroidRuntime(14313): at android.media.AudioRecord.startRecording(AudioRecord.java:515)
    E/AndroidRuntime(14313): at dalvik.system.NativeStart.run(Native Method)@

    Has anybody else had troubles with getting their code to run on Qt 5.2?
    Also, I don’t this it is a permissions error.

    Make sure you have updated your libraries and make a full rebuild of your project (clean, rebuild, run).
