I just got started with Juce development for Android and wanted to build the example app “AudioLatencyDemo” for an Android 9 phone. For this i downloaded the 5.4.4 library. After compiling with the Jucer I get in AndroidStudio the error that none of the referred standard library classes can be resolved with the library itself (see attached the library class AudioChannelSet, which cannot find any data type or other library classes). Building the same C++ example code for Visual Studio on the other side leads to a running programm. Do you have any idea what might have been wrong at the build process? Interesting is that when the JuceHeader.h file is additionaly included in a library class e.g. the AudioChannelSet class for test reasons, all definitions and types are succesfully loaded. The newest Android Studio 3.5 and Gradle plugin version 3.5.0, and Gradle version 5.6.1 has been used.
