Question

I am building an application for Android 2.2 which is based on a photo library. There is an option to take picture from camera and use it in the application. I am expecting:

1. To enable the camera from the application.

2. To take the picture.

3. To automatically close the camera and show the captured picture inside the application

Unfortunately, I am not able to get the captured image to the application. Once photo is taken, camera is not closing automatically or returning to the app. Now I have to click the back button to go to the app and select the picture manually select from SD card. Camera is opening through intent and I am using the following class.

You need to do two things. Start the Camera app and tell it where to store the picture that it takes:

File photo = new File(Environment.getExternalStorageDirectory(),  "myFile.jpg");
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
startActivityForResult(intent, myRequestCode);

When the user closes the Camera app, you app and Activity will be resumed. So you must override onActivityResult to get the result:

if (resultCode == myRequestCode){
  File photo = new File(Environment.getExternalStorageDirectory(), "myFile.jpg");
  // open it, show it, insert into MediaStore whatever
}

If you don’t provide the place to save, you can alternatively retrieve it using either intent.getData or intent.getParcelableExtra using Intent.EXTRA_STREAM.
