The image is not getting saved on my phone :(. Also, I want only a small portion of the image which lies inside the rectangle (kind of crosshair one) that is present in the texture view, how can I do this?

[@LegoBuilderAJH]

love the very little explanation on what anything is or how it works or the fact that the link to the source code is so infested by ads you can't actually get to it. The fact that half of the variables he's typing in aren't initialized prior to making them for example textureView, view or .getId and the list goes on wich results in a few paragraphs of code that more holes in it than a peg board but hey on the bright side it's better than the legit android developer website that just provides a basic explanation that you can't fully understand because there's so many technical terms it makes your head spin and when you try to find out what they mean it sends you down a rabbit hole that takes hours to figure out. and if you try to get the online coding classes from google udacity it's so outdated it provides little to no help especially with something like this. it's not this dudes fault just as a new guy to the world of coding it's really frustrating

[@haykmkrtchyan7093]

Hi. Can you recommend me what to use. Relative layout or Constraint layout? You used here relative, but what you think, what's better?

[@eddydn71]

I want use Relative layout for simple layout design :)

[@haykmkrtchyan7093]

But if i'm creating a full application, may i use relative? Or i need constraint? Thanks.

[@haykmkrtchyan7093]

I'm using relative, but sometimes my application freezes. Example i have drawer layout with items. When i click on item, than opens fragment and closes the drawer. The drawer close part freezes a little.

This seems to be the one relatively least complicated example I can find. Though it's very code dense for the latest and greatest support for cameras. Has Google posted any official guides or examples on how to use camera2 API? Or any reason as to why so much code is involved to use it?

thank you very much! your videos are readlly helpfull. i want show grid lines on camera Can you tell me how to do it?

[@eddydn71]

12down voteaccepted If you want to draw the lines dynamically as per your screen size then you should use the following code in your camera preview class. @Override protected void onDraw(Canvas canvas) { if(grid){ // Find Screen size first DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics(); int screenWidth = metrics.widthPixels; int screenHeight = (int) (metrics.heightPixels*0.9); // Set paint options paint.setAntiAlias(true); paint.setStrokeWidth(3); paint.setStyle(Paint.Style.STROKE); paint.setColor(Color.argb(255, 255, 255, 255)); canvas.drawLine((screenWidth/3)*2,0,(screenWidth/3)*2,screenHeight,paint); canvas.drawLine((screenWidth/3),0,(screenWidth/3),screenHeight,paint); canvas.drawLine(0,(screenHeight/3)*2,screenWidth,(screenHeight/3)*2,paint); canvas.drawLine(0,(screenHeight/3),screenWidth,(screenHeight/3),paint); } } You also need to add the following line in the constructor of your camera preview class:this.setWillNotDraw(false);

Great video. It helped a lot. I had one question. How to open the image you clicked immediately after you captured it from the app. In a new activity i believe. But i tried using Intent on btnCapture. The app just hangs and quits. (Using Android Virtual Device API 27)

[@eddydn71]

You are right to use Intent and start new activity , you can show me your logcat when your app is close

[@pratzsss]

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_camera); textureView = (TextureView)findViewById(R.id.textureView); //From Java 1.4, you can use keyword 'assert' to check expression true or false assert textureView!=null; textureView.setSurfaceTextureListener(textureListener); btnCapture = (Button)findViewById(R.id.btnCapture); btnCapture.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { takePicture(); openPictureActivity(); finish(); } }); } private void openPictureActivity() { Intent i = new Intent(this, PictureActivity.class); startActivity(i); }

[@eddydn71]

Make sure if you run it on android emulator / phone with API over 6.0 (Marshallow and higher) , you should request run-time permission

"Session has been closed; further changes are illegal." At this part: cameraDevice.createCaptureSession(outputSurface, new CameraCaptureSession.StateCallback() { @Override public void onConfigured(@NonNull CameraCaptureSession session) { try { cameraCaptureSession.capture(captureBuilder.build(), captureCallback, mBackgroundHandler); } catch (CameraAccessException e) { e.printStackTrace(); } }... welp? :/

[@AgonizedCupid]

Hi, Thanks for your all great tutorials. I was trying to capture an image and set on ImageView using Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); if (takePictureIntent.resolveActivity(getPackageManager()) != null) { startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); } it's working on real device (Android-5) but when I am checking on latest android like Android-9 on emulator it's not working. please give me a solution. my main mative is to take a picture and set it on imageview that's is.

[@eddydn71]

Have you request Camera permission for Android above level 6 ???

[@AgonizedCupid]

EDMT Dev yes I have provided all the permission for runtime. Actually it works if I visualise a thumbnail image from the taken pictures but when I try to set the actual picture that has been taken by camera exactly on image view then it crash latest android and work perfectly on lower android like 5 . Example: I can use image uri directly from onActivityResult and it works for lower android but crash on latest android. If you please make a video on it or please if you have time to check my code that will be great help . It’s a very small code with one activity you know.
