Taking a picture and saving it into gallery in a separate folder - java

I have made an application where the user can take a photo and save it into their gallery in a separate folder named "SOC". This works on one of my Android devices however on the other device the user can take the picture but the image doesn't save for some reason. The device the image saves on is Android 4.2 the device it does not save the image on is Android 5.0 not sure if this has anything to do with it.
My Code is as fallows
static final int REQUEST_IMAGE_CAPTURE = 1;
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
public void onClickbtnCamera(View v)
{
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
Uri uriSavedImage = Uri.fromFile(new File("/storage/emulated/0/DCIM/SOC","QR_"+timeStamp+ ".png"));
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent, 1);
}
#Override
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
if (requestCode == 1) {
//Check for succesful result code
if (resultCode == -1) {
//Show your Toast when the result is a success.
Toast toast = Toast.makeText(getApplicationContext(),
"Picture is saved in your SOC gallery", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 100, 0);
toast.show();
}
}
}

Image captured from camera is not displaying

I am trying to capture an image and then display it on the screen using another activity. I am able to successfully capture the images and save them in my desired directory. However, even after hours of struggle, I am still unable to solve this problem. The touch listener is added to the screen though there's no image.
Here's the code:
private void takeImage(){ Intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "MyImages");
imagesFolder.mkdirs();
File image = new File(imagesFolder, "QR_" + timeStamp + ".png");
Uri uriSavedImage = Uri.fromFile(image);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent, PHOTO_TAKEN); }
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PHOTO_TAKEN){
data.putExtra(SET_CAPTURED_IMAGE, true);
} else{
Log.d(MainActivity.DEBUGTAG, "Photo = null");
}
}
Now in another activity (ImageActivity):
addTouchListener() is called in onCreate() method of this activity.
Till here, the image is successfully captured and saved in the directory.
private void addTouchListener(){
ImageView imageView = (ImageView)findViewById(R.id.unlocker_image);
Bundle extras = getIntent().getExtras();
//The following if block is not executed
if (extras != null && extras.getBoolean(MainActivity.SET_CAPTURED_IMAGE)){
Uri imageUri= Uri.parse(extras.getString(MediaStore.EXTRA_OUTPUT));
imageView.setImageURI(imageUri);
} else {
imageView.setImageResource(R.drawable.unlocker_image);
//this is the default image added
}
imageView.setOnTouchListener(collector);
}
At this point, the touch listener is added but there's no image.

Saving an image into my Gallery

I'm making an Android application in Android studio where the user can take a photo and save it into a new folder in their gallery. Currently the application takes the pictures fine but doesn't save the image into the new "SOC" folder in my gallery. I'm not getting any errors and I have no idea why it's not saving the image. Any help would be appreciated.
My code is as fallows
static final int REQUEST_IMAGE_CAPTURE = 1;
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
public void onClickbtnCamera(View v)
{
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
Uri uriSavedImage=Uri.fromFile(new File("/storage/emulated/0/DCIM/SOC","QR_"+timeStamp+ ".png"));
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent, 1);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
//Check for succesful result code
if (resultCode == -1) {
//Show your Toast when the result is a success.
Toast toast = Toast.makeText(getApplicationContext(),
"Picture is saved in your SOC gallery", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 100, 0);
toast.show();
}
}
}
I think you must manually add your new photo Uri to Media Content Provider.
take a look here
Call this method in your Activity for result
protected void addPhotoToGallery() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(getCurrentPhotoPath());
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.getActivity().sendBroadcast(mediaScanIntent);
}
you should save the photo path before launching the intent and then getCurrentPhotoPath() must get that path

How can I save an image to my app?

I am making an app that will let users take photos and save them to the app, which will be password protected. So far, the app can take a picture, retrieve it, and set it to an image view. However, when I restart the app the image goes away. How can I save it?
int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
Uri imageUri;
public void takePic(View view){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "filename_" +
String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra("data", imageUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
Bundle extras = data.getExtras();
Log.e("URI", imageUri.toString());
Bitmap bmp = (Bitmap) extras.get("data");
ImageView imageView = (ImageView) findViewById(R.id.imageView);
imageView.setImageBitmap(bmp);
}
else if (resultCode == RESULT_CANCELED) {
Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT);
}
}
}
That imageUri you pass to the Intent- the image file is saved there. Just save the URI in SharedPreferences or other persistant storage and check that storage next time you launch your app.
This code is working on me :
private void takePicture() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
try {
mImageCaptureUri = null;
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
mImageCaptureUri = Uri.fromFile(mFileTemp);
}
else {
mImageCaptureUri = InternalStorageContentProvider.CONTENT_URI;
}
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
intent.putExtra("return-data", true);
startActivityForResult(intent, REQUEST_CODE_TAKE_PICTURE);
} catch (Exception e) {
Log.d("error", "cannot take picture", e);
}
}
This is how to define mFileTemp
String state = Environment.getExternalStorageState();
File mFileTemp;
if (Environment.MEDIA_MOUNTED.equals(state)) {
//this is like that
//any folder name/you can add inner folders like that/your photo name122412414124.jpg
mFileTemp = new File(Environment.getExternalStorageDirectory()+File.separator+"any folder name"+File.separator+"you can add inner folders like that"
, "your photo name"+System.currentTimeMillis()+".jpg");
mFileTemp.getParentFile().mkdirs();
}
else {
mFileTemp = new File(getFilesDir()+"any folder name"+
File.separator+"myphotos")+File.separator+"profilephotos", "your photo name"+System.currentTimeMillis()+".jpg");
mFileTemp.getParentFile().mkdirs();
}
Your global variables
private Uri mImageCaptureUri;
private File mFileTemp;
1) Define your global variables
2) Then define mFileTemp
3)Then trigger takePicture() method

There is no requirement that the camera send back the Uri in the Intent delivered to onActivityResult(). You already know what the Uri is, as you put it in EXTRA_OUTPUT. You just need to use that value. Be sure to include it in your saved instance state, as your process may be terminated while the camera app is in the foreground.

onActivityResult from camera gives null intent

so this was working lovely till yesterday when I upgraded my phone to 5.0.0 and tested the application out in a 5.0.0 emulator. Basically the purpose is to allow the user to take a photo, return it, open it to allow cropping then return it and set it as an imageview.
Everything worked fine before but now the intent in onActivityResult is null.
Here's code:
public void takeDisplayPicture(View view) {
final String TAKE_DISPLAY_PICTURE = "Take Display Picture";
Log.d(TAKE_DISPLAY_PICTURE, "Clicked");
try {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_CAPTURE);
} catch (ActivityNotFoundException e) {
String msg = "Your device doesn't support a camera!";
Toast toast = Toast.makeText(this, msg, Toast.LENGTH_SHORT);
toast.show();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
final String RETURN_DISPLAY_PICTURE = "Return Display Picture";
Log.d(RETURN_DISPLAY_PICTURE, "Returned");
if (resultCode == RESULT_OK && requestCode == CAMERA_CAPTURE) {
picUri = data.getData();
performCrop(picUri);
} else if (requestCode == PIC_CROP) {
Bundle extras = data.getExtras();
bitmap = extras.getParcelable("data");
displayPicture.setImageBitmap(bitmap);
}
}
private void performCrop(Uri picUri) {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(picUri, "image/*");
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
cropIntent.putExtra("return-data", true);
startActivityForResult(cropIntent, PIC_CROP);
} catch (ActivityNotFoundException e) {
String msg = "Your device doesn't support the crop action!";
Toast toast = Toast.makeText(this, msg, Toast.LENGTH_SHORT);
toast.show();
}
}
First, Android does not have a CROP Intent.
With respect to the null Uri, it is supposed to be null. Quoting the ACTION_IMAGE_CAPTURE documentation:
The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field.
You do not have EXTRA_OUTPUT, and so you are supposed to get your image via the poorly-documented (Bitmap)data.getExtras().get("data");.
