Here seems to be 2 workarounds:
Either i dynamically set the surface view "camera_image_view" at the time user try to capture screen. But i tried that in onClick and it is not working. Please suggest me some changes if you found any bug in that.
Clicking a full screen image and then cropping it to whatever fits inside the length and width of "camera_image_view". I tried this also but i think there is some flaw in this line:
Bitmap resizedbitmap1=Bitmap.createBitmap(bitmap, 0,0,mCameraPreview.getWidth(), mCameraPreview.getHeight());
as it is generating some broken colors instead of the cropped image.
So please help me with any of the two ways as both will work for me.

How to add autofocus to surface view?

I am working on a QR decoder app in which i have created a SurfaceView to display camera output and a ImageButton to select an image from gallery.
I am using google play services to decode the QR code which requires to use surface view to scan the QR using camera. But it is not focusing on its own.
Below is the code for the same.
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.util.SparseArray;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;
import com.google.android.gms.vision.CameraSource;
import com.google.android.gms.vision.Detector;
import com.google.android.gms.vision.Frame;
import com.google.android.gms.vision.barcode.Barcode;
import com.google.android.gms.vision.barcode.BarcodeDetector;
public class Scanner extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scanner);
final SurfaceView cameraView = (SurfaceView) findViewById(R.id.camera_view);
BarcodeDetector barcodeDectector = new BarcodeDetector.Builder(this).setBarcodeFormats(Barcode.QR_CODE).build();
final CameraSource cameraSource = new CameraSource.Builder(this,barcodeDectector).setRequestedPreviewSize(1920,1080).build();
cameraView.getHolder().addCallback(new SurfaceHolder.Callback() {
#Override
public void surfaceCreated(SurfaceHolder surfaceHolder) {
try {
cameraSource.start(cameraView.getHolder());
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
}
#Override
public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
cameraSource.stop();
}
});
barcodeDectector.setProcessor(new Detector.Processor<Barcode>() {
#Override
public void release() {
}
#Override
public void receiveDetections(Detector.Detections<Barcode> detections) {
final SparseArray<Barcode> barcodes = detections.getDetectedItems();
//QRcode found hence move to intent action.
if( barcodes.size() != 0){
Intent i = new Intent(Scanner.this,Verify.class);
i.putExtra("xml",barcodes.valueAt(0).displayValue);
startActivity(i);
}
}
});
ImageButton scanImage = (ImageButton) findViewById(R.id.scanImage);
scanImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//button action to be added
}
});
}
}
The activity_scanner.xml is as follows.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"">
<SurfaceView
android:layout_width="match_parent"
android:layout_height="400dip"
android:layout_weight="70"
android:id="#+id/camera_view"
android:layout_alignParentLeft="true"
/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/scanImage"
android:layout_below="#+id/camera_view"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:src="#drawable/ic_image_black_48dp"
android:layout_alignRight="#+id/camera_view"
android:layout_alignEnd="#+id/camera_view" />
</RelativeLayout>

Try extending Surface view like this, and setFocusable(true).
public class CameraView extends SurfaceView implements SurfaceHolder.Callback {
public CameraView(Context context) {
super(context);
getHolder().addCallback(this);
setFocusable(true);
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
}
EDIT 1:
Then in layout you can use this class like this,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://s...content-available-to-author-only...d.com/apk/res/android"
xmlns:tools="http://s...content-available-to-author-only...d.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<com.abhayjatindoshi.encryptorcode.qrlogin.javaclass.CameraView
android:layout_width="match_parent"
android:layout_height="400dip"
android:layout_weight="70"
android:id="#+id/camera_view"
android:layout_alignParentLeft="true"
/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/scanImage"
android:layout_below="#+id/camera_view"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:src="#drawable/ic_image_black_48dp"
android:layout_alignRight="#+id/camera_view"
android:layout_alignEnd="#+id/camera_view" />
</RelativeLayout>
Use Layout like above.

try this:
cameraView.requestFocus();

cameraView.setFocusableInTouchMode(true);
cameraView.setFocusable(true);
cameraView.requestFocus();

Above did not solved mine "focus" problem but i come a cross other solution which helped me:
private void setCamFocusMode(){
if(null == mCamera) {
return;
}
/* Set Auto focus */
Parameters parameters = mCamera.getParameters();
List<String> focusModes = parameters.getSupportedFocusModes();
if(focusModes.contains(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE)){
parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE);
} else
if(focusModes.contains(Camera.Parameters.FOCUS_MODE_AUTO)){
parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO);
}
mCamera.setParameters(parameters);
}
oryginally posted here:
https://stackoverflow.com/a/27092999/6225516

If somebody still looking for this yet, I've solved it by adding .setAutoFocusEnabled(true) before .build, in the line:
BarcodeDetector barcodeDectector = new BarcodeDetector.Builder(this)
.setBarcodeFormats(Barcode.QR_CODE)
.build();*

Android Camera Bug

i want to make a very simple application and I want to open the camera in a Relative Layout, but I see only a black screen instead of the camera.
The code i very simple
public class MainActivity extends AppCompatActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void button(android.view.View v){
android.hardware.Camera camera = android.hardware.Camera.open();
RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.video);
SurfaceView surfaceView = new SurfaceView(getApplicationContext());
relativeLayout.addView(surfaceView);
SurfaceHolder surfaceHolder = surfaceView.getHolder();
try {
camera.setPreviewDisplay(surfaceHolder);
camera.startPreview();
} catch (IOException e) {};
}
}
How can I fix this?

With the code below you can open the camera when clicking on the button, take a picture and display it in your image view.
Don't forget to edit YOUR_PROJECT before testing/using it.
Your Java file:
package YOUR_PROJECT;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
ImageView iv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Initialize Image view and Buttons
iv = (ImageView) findViewById(R.id.imageView);
Button btnCapture = (Button) findViewById(R.id.button_camera);
//Set listener on Capture button
btnCapture.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent c = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //Implicit Intent
startActivityForResult(c, 0);
}
});
}
//Override method onActivityResult used to retreive the image
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Bitmap m = (Bitmap) data.getExtras().get("data");
iv.setImageBitmap(m);
iv.setScaleType(ImageView.ScaleType.FIT_XY);
}
}
Your XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

Flashlight app exception: "Fail to connect to camera service"

I know, I'm using outdated stuff in my code, but that's probably because I have not seen anyone building flashlight app for Marshmallow. If anyone can suggest new code it will be helpful or correct my code(given above) will be thankful.

Android custom camera app retake often crashes

I am developing my own custom camera app,while running the application if I click the capture button my camera will capture the current position.what I actually need is retaking a photo whenever I need.But if I click the retake(take photo) button the app will crash.Here I attached my code below.So any one please help me to resolve the error.

I think the reason is you called cameraObject.release(); in onPictureTaken. You can remove it. And, don't forget to call startPreview() again.
Because:
This method is only valid when preview is active (after
startPreview()). Preview will be stopped after the image is taken;
callers must call startPreview() again if they want to re-start
preview or take more pictures. This should not be called between
start() and stop().
After calling this method, you must not call startPreview() or take
another picture until the JPEG callback has returned.

cameraObject.release();
Remove this line from tour PictureCallback. Now you know reason your app crash is quite straight to me , you are not start camera and preview also after you capture image. Preview is something stop after you call PictureCallback ,you have resume it manually.
IF you dont want to manage this thing then i can advise you to use cwac-camera library which is simply awesome. All you need to do is extend your Fragment by CameraFragment and it will take your responsibility to manage this stuff .
Enjoy !
