无法导入android.hardware.camera2.params.StreamConfiguration

Question

1. In Android API 21 they added android.hardware.camera2.params.StreamConfiguration but for some reason Android Studio can't find it.

2. Also this class ( android.hardware.camera2.params.StreamConfigurationMap ) has a public constructor and yet it says I can't create an instance of it outside its package. Why?!

Tried this:

StreamConfigurationMap map = new StreamConfigurationMap();  //Says can only be instantiated in its package
StreamConfiguration map = new StreamConfiguration();   //can't find StreamConfiguration

Answer 1

StreamConfigurationMap does not have a public constructor.

The android.hardware.camera2.params package does not expose the StreamConfiguration class. StreamConfigurationMap does allow you to use a StreamConfiguration to obtain a configuration- the configurations available are documented here .

The StreamConfiguration class and the StreamConfigurationMap constructor are hidden from the public Android API using the @hide annotation, so you cannot use them.
