How to get image uri from camera intent?

i am trying to get the uri of the picture that have been taken from device camera. I just tried some of the advices from online but i could not manage to solve this problem here is the my code parts.
ImageView petImage;
Uri imageData;
petImage = view.findViewById(R.id.imgPetPic);
petImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try {
startActivityForResult(takePictureIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
} catch (ActivityNotFoundException e) {
// display error state to the user
Toast.makeText(getActivity(), "Camera is Not Available", Toast.LENGTH_SHORT).show();
}
}
});
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
imageData = data.getData();
Bitmap bp = (Bitmap) data.getExtras().get("data");
petImage.setImageBitmap(bp);
} else if (resultCode == RESULT_CANCELED)
Toast.makeText(getActivity(), "Cancelled", Toast.LENGTH_LONG).show();
}
}
After that code parts worked. ımageData variable is still null. How do i fix this.

How to add an image captured on camera to imageviewer in Android using java? I have tried the following code

I have added Camera permissions as well which is working perfectly but the image view is not holding the image that is captured. The manifest file is also proper still. The app isn't crashing even it is not showing any errors as well. And I even want to add the image to the database.
public class RiderProfile extends AppCompatActivity {
ImageView imgDp,imgDlFront,imgDlback;
TextView txtDp,txtDl;
Button btnSave;
public static final int CAMERA_REQUEST = 1888;
private static final String TAG = "1111";
private static final int MY_CAMERA_PERMISSION_CODE = 100;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rider_profile);
imgDp = (ImageView)findViewById(R.id.imgDp);
imgDlFront = (ImageView)findViewById(R.id.imgDlFront);
imgDlback = (ImageView)findViewById(R.id.imgDlback);
txtDp = (TextView) findViewById(R.id.txtDp);
txtDl = (TextView)findViewById(R.id.txtDl);
btnSave = (Button) findViewById(R.id.btnSave);
imgDp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo1 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDp.setImageBitmap(photo1);
}
}
});
imgDlFront.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo2 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDlFront.setImageBitmap(photo2);
}
}
});
imgDlback.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo3 = (Bitmap) data.getExtras().get("data");
Log.d(TAG, "onActivityResult: click ");
imgDlback.setImageBitmap(photo3);
}
}
});
}
}

1. #Override
public void onCameraOpen() {
Intent pictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (pictureIntent.resolveActivity(getPackageManager()) != null) {
try {
imageFile = CameraUtils.createImageFile(this);
} catch (IOException e) {
e.printStackTrace();
return;
}
imageUri = FileProvider.getUriForFile(this, getPackageName() + ".provider", imageFile);
pictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(pictureIntent, IntentRequestCode.RESULT_CODE_IMAGE_CAPTURE);
}
}
2. #Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_CODE_IMAGE_CAPTURE:
if (resultCode == RESULT_OK) {
onCaptureImage(imageFile, imageUri);
} else {
Toast.makeText(this, "Camera canceled", Toast.LENGTH_SHORT).show();
}
break;
}
}
3. void onCaptureImage(File imageFile, Uri imageUri) {
Uri uri = Uri.fromFile(imageFile);
String selectedImagePath = CameraUtils.getPath(application, uri);
File file1 = new File(selectedImagePath);
if (file1.length() != 0) {
FileAttachments b_data = new FileAttachments();
b_data.setFileName(file1.getName());
CameraUtils.writeScaledDownImage(file1, getApplication());
b_data.setFile(file1);
}
}

How to pass default image to previous activity if no image is selected

In my app, I have a camera function. User can capture image or pick from gallery.
Activity B
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_LOAD_IMAGE:
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK & null != data) {
selectedImage = data.getData();
imageView.setImageURI(selectedImage);
}
break;
case REQUEST_IMAGE_CAPTURE:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
imageView.setImageURI(null);
imageView.setImageURI(imageUri);
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
}
}
}
}
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent returnIntent = new Intent();
if(selectedImage!=null) {
returnIntent.putExtra("img_uri", selectedImage.toString());
}
setResult(Activity.RESULT_OK, returnIntent);
finish();
}
});
When submit button is clicked, it will return to previous activity.
Activity A
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == PROJECT_REQUEST_CODE) {
imgURI = Uri.parse(data.getStringExtra("img_uri"));
if (mClickedPosition == -1) {
if (obj != null)
obj.addNewItem(imgURI);
} else {
if (obj != null)
obj.changeItem(mClickedPosition, imgURI);
}
}
}
}
My question now is how to pass a default image to Activity A If
user didn't select any image ?
This is the xml imageView in Activity B
<ImageView
android:paddingTop="30dp"
android:layout_gravity="center"
android:layout_width="330dp"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#mipmap/no_image"
android:scaleType="fitXY"
android:id="#+id/imageView"
android:layout_weight="0.50" />
If no image selected, I want #mipmap/no_image return to Activity B. Is it possible ? Thanks.

You can pass an Uri of your image stored in resources by the next way:
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent returnIntent = new Intent();
if(selectedImage!=null) {
returnIntent.putExtra("img_uri", selectedImage.toString());
} else {
returnIntent.putExtra("img_uri", Uri.parse("android.resource://your.package.name/mipmap/no_image").toString());
}
setResult(Activity.RESULT_OK, returnIntent);
finish();
}
});
Then you can use it as usual Uri to show the image in ImageView.

ByDefault set value of selectedImage to "default".
Now in your addNewItem() and changeItem() check value passed in imageUri
if(imageUri.equalsIgnoreCase("default"))
// set your default image that is #mipmap/no_image
else
// set image you are getting from imageUri

Code:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_LOAD_IMAGE:
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK & null != data) {
selectedImage = data.getData();
imageView.setImageURI(selectedImage);
}else{
//set default
}
break;
case REQUEST_IMAGE_CAPTURE:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
imageView.setImageURI(null);
imageView.setImageURI(imageUri);
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
}
}else{
//set default
}
default{
//set default
}
}

You don't need to return a default image to Activity A. Like others wrote, you just have to prepare for the condition when the user doesn't select any image.
Modify your onActivityResult for Activity A like this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(data!=null){
switch (requestCode) {
case RESULT_LOAD_IMAGE:
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK) {
selectedImage = data.getData();
imageView.setImageURI(selectedImage);
}
break;
case REQUEST_IMAGE_CAPTURE:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
imageView.setImageURI(imageUri);
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
}
}
break;
default:
//Your default image goes here, when the user doesn't select either of the two options
imageView.setImageResource(R.drawable.<default_image>);
break;
}
}

I cannot use the result from Zxing to do my activity

I am new to Android, i want to use the data from QR code to set my textview.
and i want to test the data's result as well.
the QR code format is just plain Text.
the problem is after I scanned my text wasn't change.
please help me check the code
btnSendJob.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.setPackage("com.google.zxing.client.android");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent, 0);
}
//result from Zxing
#SuppressWarnings("unused")
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
TextView text1 = (TextView) findViewById(R.id.resultQR);
TextView text2 = (TextView) findViewById(R.id.textToSelectGroup);
text1.setText(contents.toString());
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel
btnSendJob.setText("failed");
}
}
}
});

I think something like this works:
import zxing.IntentIntegrator;
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result != null) {
String barcode = result.getContents();
//yadda, yadda..
}
}

default camera to take a picture in android

How to use default camera to take a picture in android ?

Uri imageUri;
final int TAKE_PICTURE = 115;
public void capturePhoto(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photoFile = new File(Environment.getExternalStorageDirectory(), "Photo.png");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
imageUri = Uri.fromFile(photoFile);
startActivityForResult(intent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImageUri = imageUri;
//Do what ever you want
}
}
}

The intent which is used to open the camera is
buttonCapturePhoto.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE);
}
});
The code which gives you the image after capturing is
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Uri uriImage;
InputStream inputStream = null;
if ( (requestCode == SELECT_IMAGE || requestCode == CAPTURE_IMAGE) && resultCode == Activity.RESULT_OK) {
uriImage = data.getData();
try {
inputStream = getContentResolver().openInputStream(uriImage);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null, options);
imageView.setImageBitmap(bitmap);
} catch (NullPointerException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setAdjustViewBounds(true);
}
}

This is a simple example.Anyway this will return the image as a small bitmap.If you want to retrive the full-sized image ,is a bit more complicated.
ImageView takePhotoView = (ImageView) findViewById(R.id.iwTakePicture);
Bitmap imageBitmap = null;
takePhotoView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
dispatchTakePictureIntent(0);
}
});
private void dispatchTakePictureIntent(int actionCode) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, actionCode);
}
private void handleSmallCameraPhoto(Intent intent) {
Bundle extras = intent.getExtras();
this.imageBitmap = (Bitmap) extras.get("data");
takePhotoView.setImageBitmap(imageBitmap);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK)
handleSmallCameraPhoto(data);
}
