android - How to move image captured with the phone camera from one activity to an image view in another activity?

Question

The first activity has a button which when clicked, opens the inbuilt camera. Now when the picture is taken, a new activity opens with the image captured in an imageView and a share button in the next activity. I have set up the activity to open after the image is taken, however I am unable to transfer image captured across activities. Please i need help or a nudge in the right direction.

The first activity which takes the picture is Takepicture.java:

import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
import android.os.Environment;
import java.io.File;
import java.util.Date;

public class TakePicture extends Activity {
Button camerabutton;
Intent intent;
int requestCode;
int resultCode;
static int REQUEST_IMAGE_CAPTURE = 1;
SharedPreferences imagepreferences;
SharedPreferences.Editor imageeditor;
private String imgPath;
Uri setImageUri;
File file;
Uri imgUri;
public String getImagePath;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.takepicture);
    camerabutton = (Button) findViewById(R.id.button6);
    imagepreferences=getSharedPreferences("image", MODE_PRIVATE);
    imageeditor=imagepreferences.edit();
    camerabutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            if (intent.resolveActivity(getPackageManager()) != null)
                startActivityForResult(intent, REQUEST_IMAGE_CAPTURE);
    }
    });
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        startActivity(new Intent(TakePicture.this, Aftertakepicture.class));
    }
}
}

the second activity, Aftertakepicture.java:

package com.example.kesandunwokolo.febclasstest;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageView;

public class Aftertakepicture extends Activity {
Button camerabutton;
ImageView saveimage;
Button sharebutton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.aftertakepicture);
    camerabutton=(Button)findViewById(R.id.button6);
    saveimage=(ImageView)findViewById(R.id.imageView2);
    sharebutton=(Button)findViewById(R.id.button7);
}
}

The takepicture.xml for the first activity:

<?xml version="1.0" encoding="utf-8"?>

<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Take Picture"
    android:id="@+id/button6" />

The aftertakepicture.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="center_vertical">

    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Take Picture"
        android:id="@+id/button6" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageView2"
        android:minHeight="100dp"
        android:minWidth="100dp" />

    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Share"
        android:id="@+id/button7" />
</LinearLayout>

please any help would be appreciated!

Here are my solution, I have tested in my environment. Hope this helps!

If using emulator to test, make sure camera supported like this
