How to access photos and camera in android using one intent

Question

If you use whatsapp and you click the attach button, a menu/popup will be inflated showing you a list of appications you can use to select images and even take pictures from your camera using the photo app

I making an app that have almost the same functionality as whatapp of accessing and taking pictures. the problem is, I can't take pictures using the photo app listed as one of apps in my popup dialog but i can take pictures when using whatsapp. When I click photo app from the dialog shown in my application, it shows me all my pictures. but when I click the photo app from whatsapp popup, it goes directly to the camera

public class ImagePickerActivity extends Activity {

private final int SELECT_PHOTO = 1;
private ImageView imageView;

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

    imageView = (ImageView)findViewById(R.id.imageView);

    Button pickImage = (Button) findViewById(R.id.btn_pick);
    pickImage.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View view) {                
            Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
            photoPickerIntent.setType("image/*");
            startActivityForResult(photoPickerIntent, SELECT_PHOTO);
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

    switch(requestCode) { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK){
            try {
                final Uri imageUri = imageReturnedIntent.getData();
                final InputStream imageStream = getContentResolver().openInputStream(imageUri);
                final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
                imageView.setImageBitmap(selectedImage);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }

        }
    }
}

In my android manifest

<uses-feature android:name="android.hardware.camera"
              android:required="true" />

What do I need to change in my code to be able to take pictures from photo app?

To access camera and photos using one intent

populate a custom dialog's listview with intents from apps that can either take pictures using camera or access photos in the storage like this

private void acquirePicture(){
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");

Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
WindowManager.LayoutParams WMLP = dialog.getWindow().getAttributes();
WMLP.gravity = Gravity.CENTER;
dialog.getWindow().setAttributes(WMLP);
dialog.getWindow().setBackgroundDrawable(
        new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.setCanceledOnTouchOutside(true);
dialog.setContentView(R.layout.about_dialog);
dialog.setCancelable(true);
lv=(ListView)dialog.findViewById(R.id.listView1);

populateDialogsListView();

dialog.show();
}

Poputate dialog's listview (lv) with apps that can perform the two actions

public void populateDialogListView(){

  PackageManager pm=getPackageManager();

 List<ResolveInfo> photoIntents = new ArrayList<>();

final List<ResolveInfo> listCam = packageManager.queryIntentActivities(
        captureIntent, PackageManager.GET_RESOLVED_FILTER);

final List<ResolveInfo> listGalley = packageManager.queryIntentActivities(photoPickerIntent, PackageManager.GET_RESOLVED_FILTER);

for (ResolveInfo activity : listCam) {
  photoIntents.add(activity);
}

for (ResolveInfo activity : listGalley) {
  photoIntents.add(activity);
}



Collections.sort(photoIntents,
        new ResolveInfo.DisplayNameComparator(pm));

AppAdapter appAdapter = new AppAdapter(pm, photoIntents);

lv.setAdapter(appAdapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position,
                            long arg3) {
        // TODO Auto-generated method stub
        ResolveInfo launchable=appAdapter.getItem(position);
        ActivityInfo activity=launchable.activityInfo;
        ComponentName name=new ComponentName(activity.applicationInfo.packageName,
                activity.name);

       IntentFilter filter = launchable.filter;

        int actioncode;
        Intent  intent = new Intent();
        Uri uri;
        if(filter.hasAction(Intent.ACTION_PICK)){
            actioncode = 1;
            uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
            intent.setData(uri);
        }else{
            actioncode = 0;
        }
        intent.setComponent(name);
        startActivityForResult(intent,actioncode);
    }
});

}

Since you are creating a custom dialog with a listview, you have to create adapter for that listview(lv) which will fill the listview with app's name and app's icon

class AppAdapter extends ArrayAdapter<ResolveInfo> {
     private PackageManager pm=null;

  AppAdapter(PackageManager pm, List<ResolveInfo> apps) {
    super(Custom_chooser.this, R.layout.row, apps);
    this.pm=pm;
  }

@Override
public View getView(int position, View convertView,
                    ViewGroup parent) {
    if (convertView==null) {
        convertView=newView(parent);
    }

    bindView(position, convertView);

    return(convertView);
}

private View newView(ViewGroup parent) {
    return(getLayoutInflater().inflate(R.layout.row, parent, false));
}

private void bindView(int position, View row) {
    TextView label=(TextView)row.findViewById(R.id.label);

    label.setText(getItem(position).loadLabel(pm));

    ImageView icon=(ImageView)row.findViewById(R.id.icon);

    icon.setImageDrawable(getItem(position).loadIcon(pm));
}

Any problem, let me know
