Prendre une photo avec l'appareil photo

Bonsoir
Voici une méthode pour prendre une photo en utilisant l'action Android :

private void doTakePhotoAction() {


Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);


File fTmp = new File(Environment.getExternalStorageDirectory(),"tmp_contact_" + String.valueOf(System.currentTimeMillis()) + ".jpg")
mImageCaptureUri = Uri.fromFile(fTmp);

intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);

try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
Log.e("doTakePhotoAction", e);
}
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK) {
return;
}

switch (requestCode) {

case CROP_FROM_CAMERA: {


final Bundle extras = data.getExtras();

if (extras != null) {
Bitmap photo = extras.getParcelable("data");

mPhoto = photo;
mPhotoChanged = true;
mPhotoImageView.setImageBitmap(photo);
setPhotoPresent(true);
}


File f = new File(mImageCaptureUri.getPath());
if (f.exists()) {
f.delete();
}

InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(mPhotoImageView, InputMethodManager.SHOW_IMPLICIT);

break;
}

case PICK_FROM_CAMERA: {

Intent intent = new Intent ("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");

intent.setData(mImageCaptureUri);
intent.putExtra("outputX", 96);
intent.putExtra("outputY", 96);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
startActivityForResult(intent, CROP_FROM_CAMERA);

break;
}
}
}
