Hi stackoverflow friends,
I need to take a picture using camera and after takin the picture go to next activity without showing the first activity. And display it in an imageview.
Below is the flow of my application
first activity-> there is button for camera intent->go to the next activity(without showing the fist activity) second activity->there i need to show the image in imageview.
I saw a lot of examples of camera intent nobody explains how to go to the next activity without showing the first and display it in imageview of second.
Any outofmemeory problem occurs while displaying images in imageview repeatedly?
Thanks in advance
In First activity :
Button b=(Button)findViewByid(R.id.button);
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
doTakePhotoAction();
}
});
private void doTakePhotoAction() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"pic_" + String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, CAMERA_RESULT);
// finish();
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
}
protected void onActivityResult(int requestCode,
int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}
if (requestCode == CAMERA_RESULT) {
Intent intent = new Intent(this, nextimage.class);
// here you have to pass absolute path to your file
intent.putExtra("image-path", mUri.getPath());
intent.putExtra("scale", true);
startActivity(intent);
finish();
}
}
In nextimage.class you can set one image view and get the imagepath from putExtra and place it in imageview.
String mImagePath = extras.getString("image-path");
Bitmap mBitmap = getBitmap(mImagePath);
private Uri getImageUri(String path) {
return Uri.fromFile(new File(path));
}
private Bitmap getBitmap(String path) {
Uri uri = getImageUri(path);
InputStream in = null;
try {
in = mContentResolver.openInputStream(uri);
return BitmapFactory.decodeStream(in);
} catch (FileNotFoundException e) {
Log.e(TAG, "file " + path + " not found");
}
return null;
}
place the bitmap in the imageview.you have to create imageview in secondActivity.
use a camera intent....here's a simple code
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.widget.ImageView;
public class CameraIntent extends Activity {
final static int CAMERA_RESULT = 0;
ImageView imv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CAMERA_RESULT);
}
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_OK)
{
Get Bundle extras = intent.getExtras();
Bitmap bmp = (Bitmap) extras.get("data");
imv = (ImageView) findViewById(R.id.ReturnedImageView);
imv.setImageBitmap(bmp);
}
}
}
Use Following Code for that, it will solve your problem.
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
onActivityResult() Method:-
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_PIC_REQUEST) {
bmpImage = (Bitmap) data.getExtras().get("data");
drawable = new BitmapDrawable(bmpImage);
mImageview.setImageDrawable(drawable);
}
}
}

How can I take picture from LinearLayout and save it to gallery? For example my LinearLayout name is ll I want to take picture from ll and save it to the gallery.
I think you mean to take photo from your mobile desktop programmatically ?if so use intent to take photo.you can search the net for intent to take photo.
you can use this block of code.
private static final int TAKE_PICTURE = 1;
private Uri imageUri;
public void takePhoto(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
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 selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
Log.e("Camera", e.toString());
}
}
}
}
I want to launch the camera once a user opens up my application.
Right now I have this, and it works fine. When the user launches my application, it automatically opens up the camera. However, then the user hits the "back" button after taking an image, it opens up a blank activity.
How do I get it to go back to the camera?
public class MainActivity extends AppCompatActivity {
private static final int REQUEST_TAKE_PHOTO = 0;
// The URI of photo taken with camera
private Uri mUriPhotoTaken;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
takePhoto();
}
// Deal with the result of selection of the photos and faces.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Uri imageUri;
if (data == null || data.getData() == null) {
imageUri = mUriPhotoTaken;
} else {
imageUri = data.getData();
}
Intent intent = new Intent(MainActivity.this, Result.class);
intent.setData(imageUri);
startActivity(intent);
}
}
// Launch the camera to allow the user to take a photo
public void takePhoto(){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if(intent.resolveActivity(getPackageManager()) != null) {
// Save the photo taken to a temporary file.
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
try {
File file = File.createTempFile("IMG_", ".jpg", storageDir);
mUriPhotoTaken = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mUriPhotoTaken);
startActivityForResult(intent, REQUEST_TAKE_PHOTO);
} catch (IOException e) {
Log.d("ERROR", e.getMessage());
}
}
}
}
Try to call takePhoto() method in the onStart() instead of onCreate() and then call the finish() method into the onStop().
Try it.
#Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent(this, ActivityYouWantToOpen.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
finish();
}
I'm Currently trying to take a photo from the default camera intent from the MainActivity and then put that image in an ImageView in the same activity.
I'm saving the images such that the image taken overwrites the previously taken image (In this case, I call the image test.jpg and I store it in sdcard)
The problem I have with my code right now is the ImageView displays the photo taken the previous time the application ran.
Here is my code.
public class MainActivity extends Activity
{
ImageView imv;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imv = (ImageView)findViewById(R.id.imv);
Uri uri = null;
String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/test.jpg";
try
{
uri = takePhoto(path);
}
catch(Exception e)
{
e.printStackTrace();
}
imv.setImageURI(uri);
}
private Uri takePhoto(String path) throws IOException
{
File photo = new File(path);
photo.createNewFile();
Uri fileUri = Uri.fromFile(photo);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(cameraIntent, 0);
fileUri = Uri.fromFile(new File(path));
return fileUri;
}
}
Try to set image in onActivityResult as below:
protected void onActivityResult(int requestCode, int resultCode, Intent ata)
{
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
imv = (ImageView)findViewById(R.id.imv);
Bitmap photo = (Bitmap) data.getExtras().get("data");
imv.setImageBitmap(photo);
}}}
private static final int PICK_CONTACT_REQUEST = 0 ;
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == PICK_CONTACT_REQUEST) {
if (resultCode == RESULT_OK) {
imv.setImageURI(uri);
}
}
}
Set the image in onactivity result it will show new Image taken from the camera .
Try this,
private Uri takePhoto(String path) throws IOException
{
File photo = new File(path);
photo.createNewFile();
if(photo.exists())
photo.delete();
photo = new File(path);
Uri fileUri = Uri.fromFile(photo);
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(cameraIntent, 0);
fileUri = Uri.fromFile(new File(path));
return fileUri;
}
Google offers this versatile code for taking photos via an intent:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
The problem is that if you're like me and you want to pass the photos as extras, using EXTRA_OUTPUT seemingly runs off with the photo data and makes subsequent actions think the intent data is null.
It appears this is a big bug with Android.
I'm trying to take a photo then display it as a thumbnail in a new view. I'd like to have it saved as a full sized image in the user's gallery. Does anyone know a way to specify the image location without using EXTRA_OUTPUT?
Here's what I have currently:
public void takePhoto(View view) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
// takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePictureIntent, CAMERA_REQUEST_CODE);
}
/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(int type){
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
#SuppressLint("SimpleDateFormat")
private static File getOutputMediaFile(int type){
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "JoshuaTree");
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
Log.d("JoshuaTree", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else {
return null;
}
return mediaFile;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
handleSmallCameraPhoto(data);
}
}
}
private void handleSmallCameraPhoto(Intent intent) {
Bundle extras = intent.getExtras();
mImageBitmap = (Bitmap) extras.get("data");
Intent displayIntent = new Intent(this, DisplayPhotoActivity.class);
displayIntent.putExtra("BitmapImage", mImageBitmap);
startActivity(displayIntent);
}
}
If you specified MediaStore.EXTRA_OUTPUT, the image taken will be written to that path, and no data will given to onActivityResult. You can read the image from what you specified.
See another solved same question here: Android Camera : data intent returns null
Basically, there are two ways to retrieve the image from Camera, if you use to send a captured image through intent extras you cannot retrieve it on ActivityResult on intent.getData() ' because it saves the image data through extras.
So the idea is:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
And retrieving it on ActivityResults checking the retrieved intent:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (resultCode == RESULT_OK) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (intent.getData() != null) {
ParcelFileDescriptor parcelFileDescriptor = context.getContentResolver().openFileDescriptor(intent.getData(), "r"); 
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
} else {
Bitmap imageRetrieved = (Bitmap) intent.getExtras().get("data");
}
}
}
}
Here is how you can achieve what you want:
public void onClick(View v)
{
switch(v.getId())
{
case R.id.iBCamera:
File image = new File(appFolderCheckandCreate(), "img" + getTimeStamp() + ".jpg");
Uri uriSavedImage = Uri.fromFile(image);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
i.putExtra("return-data", true);
startActivityForResult(i, CAMERA_RESULT);
break;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch(requestCode)
{
case CAMERA_RESULT:
if(resultCode==RESULT_OK)
{
handleSmallCameraPhoto(uriSavedImage);
}
break;
}
}
private void handleSmallCameraPhoto(Uri uri)
{
Bitmap bmp=null;
try {
bmp = BitmapFactory.decodeStream(getContentResolver().openInputStream(uri));
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
Intent displayIntent = new Intent(this, DisplayPhotoActivity.class);
displayIntent.putExtra("BitmapImage", bmp);
startActivity(displayIntent);
}
private String appFolderCheckandCreate(){
String appFolderPath="";
File externalStorage = Environment.getExternalStorageDirectory();
if (externalStorage.canWrite())
{
appFolderPath = externalStorage.getAbsolutePath() + "/MyApp";
File dir = new File(appFolderPath);
if (!dir.exists())
{
dir.mkdirs();
}
}
else
{
showToast(" Storage media not found or is full ! ");
}
return appFolderPath;
}
private String getTimeStamp() {
final long timestamp = new Date().getTime();
final Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(timestamp);
final String timeString = new SimpleDateFormat("HH_mm_ss_SSS").format(cal.getTime());
return timeString;
}
Edit:
Add these to Manifest:
Starting Api 19 and above READ_EXTERNAL_STORAGE should be declared explicitly
*<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />*
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
to you manifest.
Try this one android.provider.MediaStore.EXTRA_OUTPUT hope will solve your bug. The following code works for me:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
I was facing same problem, every time getting null while retrieving data on other activity with getIntent().getData() then solved by writting complete android.provider.MediaStore.EXTRA_OUTPUT this solved my bug.
I'm having trouble using the camera when there's no sdcard present.
When there is an sdcard, using the camera is trivial, e.g.
http://www.vogella.com/articles/AndroidCamera/article.html + a plethora of other examples.
However, I need to make my app available to devices which don't have SD cards, (e.g. the Sony Xperia series.) I've tried modifying the code such that I'm using the internal storage (I think):
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(getDir("myDirec", Context.MODE_WORLD_WRITEABLE), "tmp_photo_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
file.createNewFile();
mImageCaptureUri = Uri.fromFile(file);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
intent.putExtra("return-data", true);
However, upon result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intentReturn) {
if (resultCode != RESULT_OK)
return;
String path = mImageCaptureUri.getPath();
Bitmap bitmap = BitmapFactory.decodeFile(path);
...
bitmap is null.
Which leads me to believe that there's some permissions issue....maybe?
I've tried some of the other internal storage options, http://developer.android.com/guide/topics/data/data-storage.html#filesInternal e.g. getFilesDir() but the same result: null bitmap.
Has anyone had any success in using the camera without an sdcard?
Try this. It works..
private Uri imageUri;
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.btnImageCapture:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File dir = context.getDir("directory", Context.MODE_PRIVATE);
File photo = new File(dir, "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, OPEN_CAMERA);
break;
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case OPEN_CAMERA:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
}
}
}
}
