implementation of both camera APIs to support older and higher android API levels

how to implement the flow of both 2 camera APIs(camera and camera2) through interface creation to support older and higher API levels.I implemented android.hardware.Camera in my app and works well for 22 and older APIs but i need to support higher API levels either.I saw this
Android camera android.hardware.Camera deprecated but i do not exactly understand how to implement in my codes an interface which will contain all the 2 cameras' methods like in the link above. my codes are:
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//Standard Intent action that can be sent to have the camera application capture an image and return it.
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);//Creating file URI to store image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);//The caller may pass an extra EXTRA_OUTPUT to control where this image will be written.
// start the image capture Intent
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
/**
* Here we store the file URL as it will be null after returning from camera
* application
*/
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
// save file URL in bundle as it will be null on screen orientation
// changes
outState.putParcelable("file_uri", fileUri);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
super.onRestoreInstanceState(savedInstanceState);
// get the file URL
fileUri = savedInstanceState.getParcelable("file_uri");
}
/**
* Receiving activity result method will be called after closing the camera
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_CAPTURE_IMAGE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// successfully captured the image
// display it in image view
previewCapturedImage();
} else if (resultCode == RESULT_CANCELED) {
// user cancelled Image capture
Toast.makeText(getApplicationContext(),

.show();
} else {
// failed to capture image
Toast.makeText(getApplicationContext(),
"Sorry! Failed to capture image", Toast.LENGTH_SHORT)

}
}}

Closed 6 years ago.
My problem after taking a photo and then createImageFile .. onActivityResult, photo does not appear on img_photo. how to make appear in img_photo ?
img_photo = (ImageView) findViewById(R.id.imgPhoto);
// take a photo from camera
imgBtnCamera = (ImageButton) findViewById(R.id.imgBtnCamera);
imgBtnCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(PhotoSubmitActivity.this,
"com.example.android.fileprovider", photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
});
Create image file
// Create image file
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
Log.v("This is totally working", "Yeah!");
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
img_photo.setScaleType(ImageView.ScaleType.CENTER_CROP);
img_photo.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}

I attended training on this link Taking Photos Simply

i had same problem too.but i solved it.
#Driyanto Saputro see in my code where i placed a comment for save Captured image in ImageView.
also Note : i am working on Custom Camera not Using Existing Camera.
i paste my code below to Save Captured image in imageView.

Trying to take a picture and then store it + have access to it

So, I have an app where I want to take a picture, store it to internal storage, and then be able to retrieve it later (presumably via its Uri). Here is what I have thus far:
This code is triggered when my custom camera button is pressed.
cameraButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Intent takePic = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = herp(MEDIA_TYPE_IMAGE);
if (file != null) {
fileUri = getOutputMediaFileUri(file);
Log.d("AddRecipeActivity", fileUri.toString());
takePic.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePic, CAMERA_REQUEST);
}
}
});
Next, I've defined two methods later on in the code(mostly taken from the android developer site):
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(File file){
return Uri.fromFile(file);
}
/** Create a File for saving an image or video */
public File herp(int type){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
Boolean a = false;
String externalDirectory= getFilesDir().getAbsolutePath();
File folder= new File(externalDirectory + "/NewFolder");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (!folder.exists()){
a = folder.mkdirs();
Log.d("AddRecipeActivity", String.valueOf(a));
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(folder.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else {
return null;
}
if(mediaFile == null){
Log.d("AddRecipeActivity", "Media file is null");
}
return mediaFile;
}
When I print my Uri (right before triggering the intent) I get the following output.
04-04 04:22:40.757 22402-22402/scissorkick.com.project2 D/AddRecipeActivity: file:///data/user/0/scissorkick.com.project2/files/NewFolder/IMG_20160404_042240.jpg
Also, when I check if the directory is made, the boolean is true.
When my camera intent's onActivityResult is run, however, the result code is 0.
Why might it fail at this point? I've defined the appropriate permissions in the manifest, and also request external storage write permissions during run time.
Edit: Added the onActivityResult:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == CAMERA_REQUEST){
Log.d("AddRecipe", String.valueOf(resultCode));
if(resultCode == RESULT_OK){
photo = (Bitmap) data.getExtras().get("data");
thumb = ThumbnailUtils.extractThumbnail(photo, 240, 240);
photoView.setImageBitmap(thumb);
//Toast.makeText(getApplicationContext(), "image saved to:\n" + data.getData(), Toast.LENGTH_SHORT).show();
}
else{
Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_SHORT).show();
}
}
}
There's some nonsense code in the onActivityResult, but the point is that the resultCode = 0 and I don't know why.

In your final activity, put the below code
data.putExtra("uri", uri);//uri = your image uri
getActivity().setResult(""result_code", data);
getActivity().finish();
Then in your onActivityResult code you can get the uri like
Uri uri = data.getExtras().getParcelable("uri");
Then you can use this Uri value to retrieve your image.

There is how i take picture in my app!
When i press my own Image Button
static final int REQUEST_IMAGE_CAPTURE = 1;
static final int REQUEST_TAKE_PHOTO = 1
static final String STATE_PHOTO_PATH = "photoPath";
ImageButton photoButton = (ImageButton) this.findViewById(R.id.take_picture_button);
photoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dispatchTakePictureIntent();
}
});
And here how manage and create/store the file with image
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
//Create a new empty file for the photo, and with intent call the camera
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException e) {
// Error occurred while creating the File
Log.e("Error creating File", String.valueOf(e.getMessage()));
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
//I have the file so now call the Camera
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
private void openImageReader(String imagePath) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri imgUri = Uri.parse(imagePath);
intent.setDataAndType(imgUri, "image/*");
startActivity(intent);
}
In the ActivityResult i only save a record in DB, with the Path of the image so i can retrieve it back and read the photo stored like file.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
//Save the path of image in the DB
db.addCompito(new Compiti(activity_name, null, mCurrentPhotoPath));
refreshListView();
}
}
If you have some screen rotation don't forget to add something like
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Save the user's current game state
savedInstanceState.putString(STATE_PHOTO_PATH, mCurrentPhotoPath);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}
public void onRestoreInstanceState(Bundle savedInstanceState) {
// Always call the superclass so it can restore the view hierarchy
super.onRestoreInstanceState(savedInstanceState);
// Restore state members from saved instance
mCurrentPhotoPath = savedInstanceState.getString(STATE_PHOTO_PATH);
}
WHY?
Because when the rotation change you can lose the file that you have created for the "new photo" and when you accept it and save it, your photopath is null and no image is created.

Camera Intent doesn't return to previous activity in some versions of android

I have implemented many imageviews with a camera icon so that when the user touches on the icon it starts the camera and when the picture is taken it returns to the original activity where the camera intent was called and display the captured image in the imageviews.
The problem is this works ok with in my Jellybean 4.2.2. But in some phones having kitkat and Jellybean 4.2.1, when the camera is loaded and the picture is taken it gives an option to save or discard the captured image (in my phone no option is given to save) and when i click save the app crashes. Sometimes even in my phone it returns to previous activity but doesn't show the captured images.

You can use android Timer Timer doc
Start timer when button is clicked
TimerTask timerTask = new TimerTask () {
#Override
public void run () {
// your code here... check if 5 image taken and cancel the timer
}
};
new Timer().schedule(timerTask, 2*60*1000);

I didn't test it, you can try it... every Url that you get in your activityResult , you put it in the ArrayList.
