I just got started in Android Programming and I am creating an android application in which the user is allowed to key in information, take a picture with ImageView implemented and SAVE the information. I've gotten up to the point where I am able to display the image taken into ImageView. However, I am unable to save the image taken into my phone's internal storage. Which means, whenever I try to save the information, including the ImageView (image from camera), only the image disappears. I've followed this guide on http://www.androidhive.info/2013/09/android-working-with-camera-api/ but it does not work as my phone has no SD card storage.
I've read a bunch of questions on here but they do not fix the problem.
So if anyone could give me a detailed procedure on how to edit this code in such a way that I can save/read the image into/from my INTERNAL storage that would be great! Thank you.
/**
* returning image / video

private static File getOutputMediaFile(int type) {
// External sdcard location
File mediaStorageDir = new File(
Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
IMAGE_DIRECTORY_NAME);
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d(IMAGE_DIRECTORY_NAME, "Oops! Failed create "

return null;
}
}

camera.setOnClickListener(new View.OnClickListener() {
@Override

// capture picture

// Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
// startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
ItemPic = (ImageView) findViewById(R.id.itempic);
entryId = getIntent().getStringExtra("ID");
if (entryId != null) {
load();
}
}

startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);
}
