2013-03-05 06:58:39 -0600	asked a question	converting bitmap to Mat ( java, android) Hi, i face problem in converting bitmap to Mat ( thru highgui) i got the image by using built-in android camera API. What i need to do is capture image from camera, change that bitmap to Mat, then apply rgb2gray. Can i know what is the correct and recommended way to perform the async initialization if i were to use the highgui only? edit ( error message): ------------------------------------------------ 03-05 21:47:44.918: E/AndroidRuntime(29461): FATAL EXCEPTION: main 03-05 21:47:44.918: E/AndroidRuntime(29461): java.lang.UnsatisfiedLinkError: Native method not found: org.opencv.highgui.Highgui.imread_1:(Ljava/lang/String;)J 03-05 21:47:44.918: E/AndroidRuntime(29461): at org.opencv.highgui.Highgui.imread_1(Native Method) 03-05 21:47:44.918: E/AndroidRuntime(29461): at org.opencv.highgui.Highgui.imread(Highgui.java:349) 03-05 21:47:44.918: E/AndroidRuntime(29461): at com.example.finalcameraapi.Main.onActivityResult(Main.java:110) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.Activity.dispatchActivityResult(Activity.java:5293) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.ActivityThread.deliverResults(ActivityThread.java:3315) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.ActivityThread.handleSendResult(ActivityThread.java:3362) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.ActivityThread.access$1100(ActivityThread.java:141) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1282) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.os.Handler.dispatchMessage(Handler.java:99) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.os.Looper.loop(Looper.java:137) 03-05 21:47:44.918: E/AndroidRuntime(29461): at android.app.ActivityThread.main(ActivityThread.java:5041) 03-05 21:47:44.918: E/AndroidRuntime(29461): at java.lang.reflect.Method.invokeNative(Native Method) 03-05 21:47:44.918: E/AndroidRuntime(29461): at java.lang.reflect.Method.invoke(Method.java:511) 03-05 21:47:44.918: E/AndroidRuntime(29461): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) 03-05 21:47:44.918: E/AndroidRuntime(29461): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) 03-05 21:47:44.918: E/AndroidRuntime(29461): at dalvik.system.NativeStart.main(Native Method)
