Crashed when pressing 'Picture' for second time

[thiyagab]

The sample worked flawlessly except for one small bug,

When I am trying to multiple pictures, and while pressing 'picture' it crashed in the second attempt,

The error was,

java.lang.IllegalStateException: maxImages (2) has already been acquired, call #close before acquiring more.
at android.media.ImageReader.acquireNextImage(ImageReader.java:501)
at com.example.ezequiel.camera2.others.Camera2Source$PictureDoneCallback.onImageAvailable(Camera2Source.java:1446)

First I tried to close the imagereader didnt work, then closing the acquired image solved the problem
