Question

I am trying to load the camera to take a photo from my android app,

my Photos.java is

private Uri imageUri;

public void takePhoto(View view) {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo = new File(Environment.getExternalStorageDirectory(),  "Pic.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);
    startActivityForResult(intent, TAKE_PICTURE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
    case TAKE_PICTURE:
        if (resultCode == Activity.RESULT_OK) {
            Uri selectedImage = imageUri;
            getContentResolver().notifyChange(selectedImage, null);
            ImageView imageView = (ImageView) findViewById(R.id.ImageView);
            ContentResolver cr = getContentResolver();
            Bitmap bitmap;
            try {
                 bitmap = android.provider.MediaStore.Images.Media
                 .getBitmap(cr, selectedImage);

                imageView.setImageBitmap(bitmap);
                Toast.makeText(this, selectedImage.toString(),
                        Toast.LENGTH_LONG).show();
            } catch (Exception e) {
                Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
                        .show();
                Log.e("Camera", e.toString());
            }
        }
    }

and this works great. But its the layout section to call this intent which I am struggling with.

I created a button to load the camera

<Button
    android:id="@+id/takePhoto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="41dp"
    android:onClick="takePhoto"
    android:text="@string/Photos_Button1" />

but now I need to have a section to show the image I have taken. How do I do that?

ALso Modify the Android Manifest file as per your use with following:-

<manifest....
  <uses-sdk
        android:minSdkVersion="3"
        android:targetSdkVersion="21" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_VIDEO" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-feature
        android:name="android.hardware.camera"
        android:required="false" />
<application....
..........
</application>
</manifest>
