I was trying so long for Camera2 api integration to my app.Its working fine for capturing image at first.But when i snap second time the preview was not coming.I tested it in genymotion nexus 5 emulator.Tried with all examples.Preview was not coming for snapping at second time.Getting this error also. java.lang.IllegalArgumentException: Surface had no valid native Surface...
and i followed this 2 codes http://inducesmile.com/android/android-camera2-api-example-tutorial/?cid=519 Github-Camera2Master.Please help anyone to resolve this error and give some links for more detailed explanation about camera 2 api
