Android : Picture manipulation after capture

I need your help, if you are kind enough, into an issue that I'm having with my Android app:

I've managed to capture a picture in my MainActivity and display it into an separate activity - PictureActivity. My code is as follows:

In my MainActivity i have

private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;

/**
 * This is called in tap on a graphic element in my MainActivity layout
 */
public void launchCamera(View v) {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
            Bitmap imageData = null;

            if (resultCode == RESULT_OK) {
                imageData = (Bitmap) data.getExtras().get("data");

                Intent i = new Intent(this, PictureActivity.class);
                i.putExtra("captured_picture", imageData);
                startActivity(i);
            } else if (resultCode == RESULT_CANCELED) {
                // User cancelled the image capture
            } else {
                Toast.makeText(getApplicationContext(), R.string.picture_capture_error, Toast.LENGTH_SHORT).show();
            }
        }
    }

My PictureActivity looks like this:

public class PictureActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_picture);

        Bitmap bitmap  = getIntent().getExtras().getParcelable("captured_picture");

        ImageView view = (ImageView) findViewById(R.id.preview_photo);
        view.setImageBitmap(bitmap);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.image_menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();


        return super.onOptionsItemSelected(item);
    }
}

My PictureActivity layout looks like this

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/preview_photo"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

This is how the final result looks so far:

Long story short, these are the things I want to do next:

• rotate the picture if the user taps on the middle button from the main action bar


• crop the picture if the user taps on the first button from the left

Next, save the image somewhere (in shared preferences or session maybe?) and, aftewords, upload it to a remote server. I say "save the image somewhere" because the user can chose to take a second picture (from a maximum of two) and perform the same action, as above, on it (by taping on the first button from the right, in the main action bar).

What I can't figure out so far is:

• how do I know what is the current image (that I see on my screen)


• how can I set it's name and it's location where it should be saved to until I upload it to the remote server


• how can I manipulate it when I tap on one of the two buttons (crop or rotate)

Sorry for the long post and thank you in advance for your help!
