Please ignore those errors. If you switch into java mode, you will see those errors are go away. I guess it is a bug of Android mode :-?? . Have you run any application in Android mode before? I ask because you need to enable debug mode in your phone. What instructions did you follow to enable your phone?

There are some instructions here: http://android.processing.org/install.html

I will suggest to install the ketai library through the Processing library manager. Beside the NFC, all the examples should work out of the box if your phone and Android mode is configure properly.

Yeah i follow the above instructions, and debug mode is enable on my phone(Setting>>Developer options>>USB debugging) now when i try to run the above example i have some warnings and the following error..

Khan47 · November 2016

And thanks a bundle for your precious time and for helping me...

Khan47 · November 2016

Another when i try to run the following example it is ok working new

but the above problem is still not solve

kfrajer · November 2016

The failed happens in the last shot. All other screenshots are warnings. Please post your code. I will suggest using ketai library instead or at least, for this testing part. Run any of the provided examples.

When posting errors, do not post screenshots. Instead, you can select the text in the console and then press ctrl+c to copy the selection. In the forum, press ctrl+v to paste those errors. Doing this will ensure your errors are 100% readable and other forum goers can find them using the search engine.

You get the same error with the ketai example?

Please format your code. Edit your post, select your code and hit ctrl+o.

@Khan47===

-- you cannot get "the same error" using ketai lib as your code does not use anything from ketai

-- you get "the same error" because you are importing and using android ProcessingCapture class about which the error is "unsupported class version"

-- what does it means i dont know and not have anytime to see in the jar

-- in conclusion dont use this lib, use ketai or the native android camera class (ketai camera is only a wrapper for that)

kfrajer · November 2016

Please use the ketai examples provided. Do not modify them. If you want to modify them or add to them, create a copy. Provided examples are a way to debug software, specially with Processing as we need to figure out if the problem is the phone, processing, Android SDK or external libraries. If you have more errors running ketai examples, copy and paste the errors below.

Khan47 · December 2016

Hi Thanks @akenaton now check the code and error i change above..

Khan47 · December 2016

And Thanks @Kfrajer the provided example work but the camera is too small on center i will try to copy the code and modify it according to my requirements if i found any problem i'll search if not found any answer i'll post it here again..Thanks a bundle for your kindness help.....

Khan47 · December 2016

I m new here and a little bit know about coding, i want to learn here from all of you.... i think i have many mistakes please forgive me.......

kfrajer · December 2016

If you have into any other problems or questions, just come and ask questions here. Doing an online search is a good option too. You will find some libraries in processing are not maintained and I am afraid com.onlylemi.processing.android is one of them.

Hi when i try to run the ketai provided examples it work, but when i copy the example to new skitch it not working, i have this message "Failed to open camera for camera ID: 0:Fail to connect to camera service"

Also the following example when i run sketch, lunch on the device. but not working..the same message

===========================

import ketai.camera.*;

KetaiCamera cam;

    void setup() {
        orientation(LANDSCAPE);
        imageMode(CENTER);
        cam = new KetaiCamera(this, 950, 540, 24);
    }

    void draw() {
        if(cam.isStarted())
            image(cam, width/2, height/2);
        else
            cam.start();
    }

    void onCameraPreviewEvent(){
        cam.read();
    }

=============================

This messages is on the console

Failed to open camera for camera ID: 0:Fail to connect to camera service

When you create a new sketch, you need to enable the permission to use the camera.

Khan47 · December 2016

How i enable the permission to use the camera.

Khan47 · December 2016

How i enable the permission to use the camera.

kfrajer · December 2016

On the Processing IDE go to the menu Android >> Sketch Permissions and then select the camera check box.

Kf

kfrajer · December 2016

An alternative:
You can also manually type it in the manifest.xml file of the android sketch. Press ctrl+k to open the sketch directory, open the manifest.xml file in your favorite text editor and add the lines. You should be able to find the line for camera permission easily on internet.
