When the user takes a picture with the camera, I want the image displayed in an ImageView and I want to save the Uri to an online database. I heard saving the Uri of a picture is better than saving the path.
So this is how I start the camera:
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(getFile(getActivity())));
String a = String.valueOf(Uri.fromFile(getFile(getActivity())));
intent.putExtra("photo_uri", a);
startActivityForResult(intent, PICK_FROM_CAMERA);
where
private File getFile(Context context){
File sdCard = Environment.getExternalStorageDirectory();
File directory = new File (sdCard.getAbsolutePath() + "/Myapp");
if (!directory.exists()) {
directory.mkdirs();
}
String filename = "bl" + System.currentTimeMillis() + ".jpg";
File newFile = new File(directory, filename);
return newFile;
}
In onActivityResult:
Bundle extras = data.getExtras();
String photo_uri = extras.getString("photo_uri"); //null
This is always null. Btw before sending the intent the Uri looks like file://... instead of content:// which is the uri when I open an image from the gallery. I don't know if that's a problem.
Also, should I save the path instead of the Uri to the database? I read that the Uri can be complicated in certain phones or Android versions. When I let the user select an image from the gallery, I save the Uri to the database, so I think the best way is saving the Uri in this case as well.
I tried out many variations, but I get null every time I try to pass a variable with the intent...
After starting the intent:
Intent intentPicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intentPicture,PICK_FROM_CAMERA);
In onActivityResult:
case PICK_FROM_CAMERA:
Uri selectedImageUri = data.getData();
InputStream imageStream = null;
try {
imageStream = getContentResolver().openInputStream(selectedImageUri);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
break;
That's all.
