Capturing and storing multiple images in android [duplicate]

Capturing and storing multiple images in android [duplicate] - android

I seem to be having trouble creating a Bitmap from fileUri.
I would like to be able to set this Bitmap to an Imageview for previewing the image, and later adding elements to the image.
Any ideas why the image does not get set properly?

#Override

Bundle savedInstanceState) {

// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.

It appears as if I have found a solution.

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() {

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.
Please help me if you can.I am posting the essential code below

The problem is with the parameter fileUri.getPath()
May be this is not properly initialized and as a result its value is null
Check the value of fileUri variable value before passing it to the function.
This will solve your problem

how to use a timer in android which causes a program to run for 2 minutes when a button is pressed and then stop automatically after two minutes

I am making an app in which i have a button which clicks pictures.Till here I have done.Now I want that the user can take pictures for only two minutes after clicking the button.And also he has to take 5 pictures.So if the timer expires and 5 pics are not taken then restart the camera or else save the picture.I don't understand how to automatically stop a timer after two minutes.

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.
/**
* flag to check if you have already lunched the handler
*/
private static boolean isHandlerLunched = false;
/**
* Delay max to take 5 pictures
*
* #value in milliseconds
*/
private static final int DELAY_MAX = 60*1000*2;
/**

private static ArrayList<String> pictureUrls = new ArrayList<String>();

private void captureImage()
{
// if it is the first click to take the first picture
if (!isHandlerLunched){
// initialize the list again
pictureUrls = new ArrayList<String>();
// lunch the handler to delay
Handler handler = new Handler();
handler.postDelayed(new Runnable(){
public void run() {
//TODO the delay is finished , you do your staff of checking
// I propose you to add the URLs of each picture in an ArrayList<String>,
// and here you check the size of this list
if (pictureUrls.size()<5) {
// do staff
} else {
// do staff
}
}
}, DELAY_MAX );
}
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
// start the image capture Intent
startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
