android - Preview mode must have started before you can take a picture -


we getting such stacktraces in our application using cwac-camera:

java.lang.illegalstateexception: preview mode must have started before can take picture @ com.commonsware.cwac.camera.cameraview.takepicture(cameraview.java:329) @ com.commonsware.cwac.camera.cameraview.takepicture(cameraview.java:277) @ com.github.randoapp.camera.randocamerahost.onautofocus(randocamerahost.java:119) @ com.commonsware.cwac.camera.cameraview.onautofocus(cameraview.java:411) @ android.hardware.camera$eventhandler.handlemessage(camera.java:824) @ android.os.handler.dispatchmessage(handler.java:99) @ android.os.looper.loop(looper.java:137) @ android.app.activitythread.main(activitythread.java:4898) @ java.lang.reflect.method.invokenative(native method) @ java.lang.reflect.method.invoke(method.java:511) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:1008) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:775) @ dalvik.system.nativestart.main(native method)

we believe can happenning because of users pressing take picture early. solution disable button while preview initializing , enable when it's done. question is: event use button enabling? there event or callback sayong preview initialized?

we believe can happenning because of users pressing take picture early

that distinct possibility.

autofocusavailable() in camerahost best option @ moment. called before preview begins , inpreview set true.

i have filed an issue better job this.
