javaCV IMREAD problem in android studio

[mmmahdiii]

Hi, stock at the first step off coding with javaCV.

my android app get closed suddenly when I use Imread.

class Smoother { public static void smooth(String filename) { Mat image = imread(filename); if (image != null) { GaussianBlur(image, image, new Size(3, 3), 0); imwrite(filename, image); } } }

public void doSomthing(View view){ try { String path=getPathImage(imageUri); Smoother.smooth(path); txtV1.setText("GOOOOOOOOOOOOD"); } catch (Exception e) { e.printStackTrace(); txtV1.setText(e.getMessage()); } }

It never fall in catch. and this closing happen after the function below in Loder.java

public static String load() { return load(getCallerClass(2), loadProperties(), Loader.pathsFirst); }

thanks' for any help

[mmmahdiii]

in AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

in build.gradle defaultConfig { multiDexEnabled true } dependencies {

implementation 'androidx.multidex:multidex:2.0.1'
implementation 'org.bytedeco:javacv:1.5.5'

}

What's the error message that you get in the log?

[mmmahdiii]

no error. I try to get error in try/catch, but noting happened in catch, just close the app.

I've face some problem, maybe I solved in wrong way. 1- I use implementation group: 'org.bytedeco', name: 'javacv', version: '1.5.5' instit of implementation group: 'org.bytedeco', name: 'javacv-platform', version: '1.5.5' 2- I use implementation 'androidx.multidex:multidex:2.0.1' to solve some errores

[saudet]

Ok, but please show me all the messages that you get in the log, including anything at the debug level.

You'll need that file to be there for OpenCV to load.

thanks.

I've updated my build.gradle defaultConfig { multiDexEnabled true } dependencies { implementation 'androidx.multidex:multidex:2.0.1' implementation group: 'org.bytedeco', name: 'javacv', version: '1.5.5' implementation group: 'org.bytedeco', name: 'openblas', version: '0.3.13' }

and my debugger turns to:

Add a dependency on javacv-platform. It will get everything that you need.

[mmmahdiii]

I Change dependency to:

I try every think I know, but I know a bit!!!

[saudet]

Make sure that Loader.load(opencv_java.class) has been called: https://github.com/bytedeco/javacpp-presets/tree/master/opencv#documentation

[mmmahdiii]

No error

[mmmahdiii]

Thanks a lot. Finally, my imread worked. my GaussianBlurr worked. my imwrite worked.

but drawing circle, faced with error, Cannot resolve method 'circle(org.bytedeco.opencv.opencv_core.Mat, org.bytedeco.opencv.opencv_core.Point, int, org.bytedeco.opencv.opencv_core.CvScalar)'

I Checkd This

don't waist your time on this issue, I ask you to update the Samples, for the beginners like me.

[saudet]

CvScalar is for the deprected C API. Use Scalar instead.

[mmmahdiii]

Thanks a million. Can you refer me to any references for deal with this thing?

[saudet]

What thing?
