Android Camera : data intent returns null

Question

I have an android application which contains multiple activities.

In one of them I\'m using a button which will call the device camera :

public void

The default Android camera application returns a non-null intent only when passing back a thumbnail in the returned Intent. If you pass EXTRA_OUTPUT with a URI to write to, it will return a null intent and the picture is in the URI that you passed in.

You can verify this by looking at the camera app's source code on GitHub:

• https://github.com/android/platform_packages_apps_camera/blob/gingerbread-release/src/com/android/camera/Camera.java#L1186

  Bundle newExtras = new Bundle();
  if (mCropValue.equals("circle")) {
      newExtras.putString("circleCrop", "true");
  }
  if (mSaveUri != null) {
      newExtras.putParcelable(MediaStore.EXTRA_OUTPUT, mSaveUri);
  } else {
      newExtras.putBoolean("return-data", true);
  }
  

I would guess that you're either passing in EXTRA_OUTPUT somehow, or the camera app on your phone works differently.
