Question

I am trying to run PhotoStream sample from following link

http://android-developers.blogspot.com/2008/09/android-photostream.html

But when i try to set the wallpaper of an image ( reference class ViewPhotoActivity.java) i am getting following error

android.content.ActivityNotFoundException:

Unable to find explicit activity class
{com.android.camera/com.android.camera.CropImage};
have you declared this activity in
your AndroidManifest.xml?

and i think the following code is causing the problem

final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
intent.setData(Uri.fromFile(mFile));
intent.putExtra("outputX", width);
intent.putExtra("outputY", height);
intent.putExtra("aspectX", width);
intent.putExtra("aspectY", height);
intent.putExtra("scale", true);
intent.putExtra("noFaceDetection", true);
intent.putExtra("output", Uri.parse("file:/" + mFile.getAbsolutePath()));
startActivityForResult(intent, REQUEST_CROP_IMAGE);

As i tried to find the solution of this problem but didn’t get any.

Answer 1

I found a way by following the LogCat while i was cropping a contact Image. It called the Intent with following parameters:

cmp=com.android.gallery/com.android.camera.CropImage

So try to replace the com.android.camera with com.android.gallery. This worked for me:

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

On some Android version, including the newest, com.android.gallery doesn’t exist anymore.
You need to use this then:

Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.google.android.gallery3d", "com.android.gallery3d.app.CropImage");
