Как отменить камеру в приложении Android ⇐ Android

[Anonymous]

Как отменить камеру, когда пользователь будет нажимать на значок левой стороны на камере в эмуляторе Android. Когда я открываю камеру и захватываю изображение растровое изображение, отправляется на image_cropping для обрезки изображения. При отмене камеры она не возвращается к предыдущей деятельности, она переходит к Image_cropping Activity. Может ли кто-нибудь помочь мне решить.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

if(requestCode == CAMERA_REQUEST)
{
if (requestCode == 0 && resultCode == 0){
Toast.makeText(getApplicationContext(),"Cancel Image Capture ", Toast.LENGTH_SHORT).show();
}else {
onCaptureImageResult(data);
}
}

if (requestCode == PROFILE_GALLERY && resultCode == RESULT_OK)
{
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();

int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String imgDecodableString = cursor.getString(columnIndex);
cursor.close();

editor.putString("profile_picformat", imgDecodableString);
editor.commit();

Intent selfiSrc = new Intent(this, Image_Cropping.class);
finish();
startActivity(selfiSrc);
}
}

btnCamera.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String picformat = "IMG_" + 0 + "_" + s.format(new Date()) + ".png";
Log.e(" picformat ", " = " + picformat);

заранее спасибо.
