[Android] NullPointerException - Attempt to invoke virtual method 'void com.swmansion.reanimated.nodes.ValueNode.setValue(java.lang.Object)' on a null object reference

[alimek]

Hello,

after switching to react-native-reanimated 1.5.0 i started to seen crashes on Android. Updating to 1.6.0 is not solving problem.

Stack trace:

E/unknown:ReactNative: Exception in native call

Changing code from

public void setValue(int nodeID, Double newValue) {
    Node node = mAnimatedNodes.get(nodeID); 
    ((ValueNode) node).setValue(newValue);
  }

to

public void setValue(int nodeID, Double newValue) {
    Node node = mAnimatedNodes.get(nodeID);
    if (node != null) {
     ((ValueNode) node).setValue(newValue);
    }
  }

is fixing problem, but not sure if this is right fix :)

Should be fixed with #560
