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
e.printStackTrace();
}
}
}
}
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);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,Uri.fromFile(new File(myFilesDir.toString()+"/temp.jpeg")));
startActivityForResult(intent, CAPTURE_IMAGE_CALLBACK);
}
catch ( ActivityNotFoundException e )
{
Log.e( TAG, "No camera: " + e );
}
catch ( Exception e )
{
Log.e( TAG, "Cannot make photo: " + e );
}
}`

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

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUI();
buttonStart.setOnClickListener(new View.OnClickListener() {

} 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);
}

}
}
}
I don't understand what has gone wrong.
Can anybody help me ...

first u need to create a directory

imagesFolder.mkdirs();
newFile = new File(newFileLocation , "vid" + ".mp4");
} catch (Exception e) {

How do i pass an uri from the onActivity result to another method in the same jave file.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) return;
if (requestCode == PICK_FROM_GALLERY) {
Uri mVideoURI = data.getData();
videoView.setVideoURI(mVideoURI);
videoView.start();
}
}
method savevideo:
public void savevideo() {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/SavedVideo/";
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();;
// create unique identifier
Random generator = new Random();
int n = 100;
n = generator.nextInt(n);
// create file name
String videoName = "Video_" + n + ".mp4";
File fileVideo = new File(dir.getAbsolutePath(), videoName);
try {
fileVideo.createNewFile();
success = true;
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Video saved!",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during video saving", Toast.LENGTH_LONG).show();
}
return true;
}
}
I would like like pass the mVideoURI to savevideo method and then save the video uri into gallery. Can someone help me with this. Any guidance/suggestion would be really helpful. Thank you.

As per my understanding from your question, you have to call a method after getting a result from another activity. so you might be called startActivitForResult(activityB) for getting the video Uri. so you will get a callback from the activityB, thus you can directly pass the video to the method saveVideo() since it is in the same Activity.
Example
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK)
return;
if (requestCode == PICK_FROM_GALLERY) {
Uri mVideoURI = data.getData();
saveVideo(videoUri);
}
}
public void saveVideo(Uri videoUri){
// do operations with uri
}
or if you can't accept any arguments in saveVideo() method you can make uri as a member variable and use inside() method
use this code-
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) return;
if (requestCode == PICK_FROM_GALLERY) {
Uri mVideoURI = data.getData();
saveVideo(mVideoURI); // methode to save uri gets called here
videoView.setVideoURI(mVideoURI);
videoView.start();
}
}
method savevideo:
public void savevideo(Uri mVideoURI) {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/SavedVideo/";
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();;
// create unique identifier
Random generator = new Random();
int n = 100;
n = generator.nextInt(n);
// create file name
String videoName = "Video_" + n + ".mp4";
File fileVideo = new File(dir.getAbsolutePath(), videoName);
try {
fileVideo.createNewFile();
success = true;
} catch (IOException e) {
e.printStackTrace();
}
if (success) {
Toast.makeText(getApplicationContext(), "Video saved!",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"Error during video saving", Toast.LENGTH_LONG).show();
}
return true;
}
}
In your code, you are only creating new file on your destination path but not write the data of source file to destination file.
So you are getting 0KB file. Use the below code code for writing a file.
void savefile(URI sourceuri)
{
String sourceFilename= sourceuri.getPath();
String destinationFilename = android.os.Environment.getExternalStorageDirectory().getPath()+File.separatorChar+"abc.mp3";
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try {
bis = new BufferedInputStream(new FileInputStream(sourceFilename));
bos = new BufferedOutputStream(new FileOutputStream(destinationFilename, false));
byte[] buf = new byte[1024];
bis.read(buf);
do {
bos.write(buf);
} while(bis.read(buf) != -1);
} catch (IOException e) {
} finally {
try {
if (bis != null) bis.close();
if (bos != null) bos.close();
} catch (IOException e) {
}
}
}
I've managed to programmatically take a photo from the camera, then display it on an imageview, and then after pressing a button, saving it on the Gallery.
It works, but the problem is that the saved photo are low resolution.. WHY?!
I took the photo with this code:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
Then I save the photo on a var using :
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
}
}
and then after displaying it on an imageview, I save it on the gallery with this function:
public void SavePicToGallery(Bitmap picToSave, File savePath){
String JPEG_FILE_PREFIX= "PIC";
String JPEG_FILE_SUFFIX= ".JPG";
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = JPEG_FILE_PREFIX + timeStamp + "_";
File filePath = null;
try {
filePath = File.createTempFile(imageFileName, JPEG_FILE_SUFFIX, savePath);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
FileOutputStream out = null;
try {
out = new FileOutputStream(filePath);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
picToSave.compress(CompressFormat.JPEG, 100, out);
try {
out.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Add the pic to Android Gallery
String mCurrentPhotoPath = filePath.getAbsolutePath();
MediaScannerConnection.scanFile(this,
new String[] { mCurrentPhotoPath }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
}
});
}
I really can't figure out why it lose so much quality while saved..
Any help please ? Thanks..
The photo you are displaying in the ImageView is a thumbnail :
data.getExtras().get("data");
Are you calling the method :
public void SavePicToGallery(Bitmap picToSave, File savePath)
with the thumbnail ?
Here you have all the steps describe to do what you want :
http://developer.android.com/training/camera/photobasics.html
data.getExtras().get("data") only get thumbnail.
To do it properly, you have to declare global uri variable
Uri imageCapturedUri ;
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
imageCaptureUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageCaptureUri);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
// mImageCaptureUri is your Uri
}
}
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();
}
}
}
}
in my camera intent:
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
this part gives me a null pointer exception.
can anyone explain why and what need to be changed??
button_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("android.media.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
startActivityForResult(intent, TAKE_PICTURE);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
}
Try the following,
public class Camera extends Activity
{
private static final int CAMERA_REQUEST = 1888;
private String selectedImagePath;
WebView webview;
String fileName = "capturedImage.jpg";
private static Uri mCapturedImageURI;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
Intent cameraIntent = new Intent(ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
#Override

{
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_REQUEST)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
Random randomGenerator = new Random();randomGenerator.nextInt();
String newimagename=randomGenerator.toString()+".jpg";
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + newimagename);
try {
f.createNewFile();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//write the bytes in file
try {
fo = new FileOutputStream(f.getAbsoluteFile());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
fo.write(bytes.toByteArray());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
uri=f.getAbsolutePath();
//this is the url that where you are saved the image
}
}
