Hi,

Could you provide more info about this issue, i.e. SDK and version you used, Android API, etc.

It'd be the best if you can provide the the steps to consistently repro this error. Thanks!

[m-anshuman2166]

I used all required jars and used same code as present in examples, but still Null pointer exception comes

[SilverDestiny]

Which example? Do you have the link to the example you used?

ML Kit has examples at https://github.com/googlesamples/mlkit

For Vision features, https://github.com/googlesamples/mlkit/tree/master/android/vision-quickstart is the vision quickstart app.
