I want to write an application that only has this functionality:
- take image using phone camera
- send it as a mail attachment to a given address
I have written the following code, and i don't understand why i cant exit camera mode (pressing the accept button has no effect)
public class MainActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
private ImageView imageView;
private File f;
public File getAlbumDir()
{
File storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
"BAC/"
);
return storageDir;
}
private File createImageFile() throws IOException {
// Create an image file name
String imageFileName =getAlbumDir().toString() +"/image.jpg";
File image = new File(imageFileName);
return image;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
photoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
f = createImageFile();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(cameraIntent, CAMERA_REQUEST);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"first.last#gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "first picture");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
Uri uri = Uri.fromFile(f);
i.putExtra(Intent.EXTRA_STREAM, uri);
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
}
}
I would appreciate any suggestions!
Thanks!
The camera does not return because your album directory does not exists. Try with
public File getAlbumDir() {
File storageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
"BAC/"
);
// Create directories if needed
if (!storageDir.exists()) {
storageDir.mkdirs();
}
return storageDir;
}
Also, since you provide an EXTRA_OUTPUT extra, the parameter data might be null in onActivityResult(). You can build the bitmap from your File object instead
Bitmap photo = BitmapFactory.decodeFile(f.getAbsolutePath());
For anyone that has the same problem, the corrected and functional code is the following:
public class MainActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
private ImageView imageView;
private File f;
public File getAlbumDir()
{
File storageDir = new File(
Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES
),
"BAC/"
);
// Create directories if needed
if (!storageDir.exists()) {
storageDir.mkdirs();
}
return storageDir;
}
private File createImageFile() throws IOException {
// Create an image file name
String imageFileName =getAlbumDir().toString() +"/image.jpg";
File image = new File(imageFileName);
return image;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
photoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
f = createImageFile();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(cameraIntent, CAMERA_REQUEST);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = BitmapFactory.decodeFile(f.getAbsolutePath());
imageView.setImageBitmap(photo);
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"raul.pop90#gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "Prima poza");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
Uri uri = Uri.fromFile(f);
i.putExtra(Intent.EXTRA_STREAM, uri);
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
}

I'm new in Android and I would create app that uses camera, store image taken from camera in device and show it in gallery? Anyone have any advice on how to do it? For now I have created the activity that allows you to take pictures but I don't know how to proceed to save and show the photos taken from the camera in the gallery.

as described in the title I would like to save the image from camera in a specific folder and then view it in the gallery of my device. So far I can access the camera, take the photo and show it in an ImageView in the same layout. How could I do? I read on the net to use the provider but using it, the images taken with the camera are not displayed in the gallery of my device. Thanks in advance to those who will answer.

This is the code i used to record video from an android device in MP4 format. The file is being created but is of 0 bytes size.
Here is my code :-
Button buttonStart;
File newFile;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUI();
buttonStart.setOnClickListener(new View.OnClickListener() {
#Override

try {
newFile = File.createTempFile("vid", ".mp4", Environment.getExternalStorageDirectory());
} catch (IOException e) {
e.printStackTrace();
}
Uri outputFileUri = Uri.fromFile(newFile);
Intent record = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
record.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(record, 5);
}
});
}
protected void initUI(){
buttonStart = (Button) findViewById(R.id.buttonRecord);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 5){
if(resultCode == RESULT_OK){
try {
newFile = File.createTempFile("vid", ".mp4", Environment.getExternalStorageDirectory());
} catch (IOException e) {
e.printStackTrace();
}
Toast.makeText(this, "Video Captured Successfully...!!", Toast.LENGTH_LONG).show();
}
}
}
I don't understand what has gone wrong.
Can anybody help me ...

I need to push an intent to default camera application to make it take a photo, save it and return an URI. Is there any way to do this?
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());
}
}
}
}
Try the following I found here
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, 0);
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == 0) {
String result = data.toURI();
// ...
}
}
It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.
Request this permission on the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
On your Activity, start by defining this:
static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;
Then fire this Intent in an onClick:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.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
Log.i(TAG, "IOException");
}
// Continue only if the File was successfully created
if (photoFile != null) {
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
}
}
Add the following support method:
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;
}
Then receive the result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
mImageView.setImageBitmap(mImageBitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.
I found a pretty simple way to do this. Use a button to open it using an on click listener to start the function openc(), like this:
String fileloc;
private void openc()
{
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = null;
try
{
f = File.createTempFile("temppic",".jpg",getApplicationContext().getCacheDir());
if (takePictureIntent.resolveActivity(getPackageManager()) != null)
{
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,FileProvider.getUriForFile(profile.this, BuildConfig.APPLICATION_ID+".provider",f));
fileloc = Uri.fromFile(f)+"";
Log.d("texts", "openc: "+fileloc);
startActivityForResult(takePictureIntent, 3);
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 3 && resultCode == RESULT_OK) {
Log.d("texts", "onActivityResult: "+fileloc);
// fileloc is the uri of the file so do whatever with it
}
}
You can do whatever you want with the uri location string. For instance, I send it to an image cropper to crop the image.
Try the following I found Here's a link
If your app targets M and above and declares as using the CAMERA permission which is not granted, then attempting to use this action will result in a SecurityException.
EasyImage.openCamera(Activity activity, int type);
#Override

}
#Override

}
Call the camera through intent, capture images, and save it locally in the gallery.

//

}
}
try this code
Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(photo, CAMERA_PIC_REQUEST);
I want to give a custom name to the image captured through the camera programmatically. I have used the snippets of codes given here how to control/save images took with android camera programmatically? but it still doesn't work and the image is stored with the default name. Why?
public class MainActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button cameraButton = (Button) findViewById(R.id.takepicture);
cameraButton.setOnClickListener( new OnClickListener(){
public void onClick(View v ){
//Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
//startActivityForResult(intent,0);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri mUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
"pic_"+ String.valueOf(System.currentTimeMillis()) + ".jpg"));
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);
startActivityForResult(intent,0);
}
});
}
}
You can try as follows...
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String fullPath = "";
File imageFile = null;
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String pictureName = "IMG_" + timeStamp + ".jpg";
fullPath = Environment.getExternalStorageDirectory() + "/ImageFolder/" + pictureName;
File dir = new File(Environment.getExternalStorageDirectory() + "/ImageFolder/");
dir.mkdirs();
imageFile = new File(fullPath);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
startActivityForResult(takePictureIntent, 1);
Try this: Here I saved image with current date and time as name:
public class CameraActivity extends Activity {
private static final int CAMERA_REQUEST = 0;
static Uri capturedImageUri=null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_junit_test);
Button cameraButton = (Button) findViewById(R.id.cameraButton);
cameraButton.setOnClickListener( new OnClickListener(){
private int CAMERA_RESULT;
public void onClick(View v ){
Calendar cal = Calendar.getInstance();
File file = new File(Environment.getExternalStorageDirectory(), (cal.getTimeInMillis()+".jpg"));
if(!file.exists()){
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}else{
file.delete();
try {
file.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
capturedImageUri = Uri.fromFile(file);
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, capturedImageUri);
startActivityForResult(i, CAMERA_RESULT);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST) {
//Bitmap photo = (Bitmap) data.getExtras().get("data");
//imageView.setImageBitmap(photo);
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap( getApplicationContext().getContentResolver(), capturedImageUri);
//imageView.setImageBitmap(bitmap);
Toast.makeText(this, "Image Saved As"+bitmap, Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block

}
}
}
}
Try This
public void CapturePhoto()
{
try

myFilesDir = new File( getFilesDir()+"/MyDir");
if(! mfilesDir.exists() )
myFilesDir.mkdirs();
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
