How to store 2mb above file size of image to database via Volley?

I have a code for uploading images from mobile to my phpmyadmin database via Volley. I can successfully upload images when it is in small ".jpg" format and also, the sizes don't exceed 2mb. Now when I choose a picture (specifically from camera pictures) that's more than that, it doesn't prompt any error and doesn't also add the picture to the database. How can I solve this and how can I store?
This is my settingsprofilefragment.java

Sharing one image uploading multiple times

I am working on a Image sharing app. I can upload image to the sever but it uploading same image multiple times(3-4 times).
I have Images Fragment where i gave floating buttons to select camera or gallery.
Images Fragment
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_images, container, false);
floatcamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
File imageFolder = new File(Environment.getExternalStorageDirectory(), "/My Children");
imageFolder.mkdir();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyymmdd_hhmmss");
String timestamp = simpleDateFormat.format(new Date());
File image = new File(imageFolder, timestamp+ ".jpg");
// Uri uriImage = Uri.fromFile(image);
camerauri = FileProvider.getUriForFile(getContext(), BuildConfig.APPLICATION_ID + ".provider", image);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.putExtra(MediaStore.EXTRA_OUTPUT, camerauri);
startActivityForResult(intent, TAKE_PICTURE);
}
});
floatgallery.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, SELECT_PICTURE);
}
});
return v;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {

startActivity(i);

Intent i = new Intent(getContext() , Upload.class);
i.putExtra("image", data.getData().toString());
startActivity(i);
}
}catch (Exception e){

}
}
After Clicking or selecting image the resulting single image display on next Activity. And there is a button to upload it. I am using Custom Volley Request as Volley does not support Multipart.

image taken from gallery is unable to set in image view

I am taking image from camera as well as from gallery,after getting the image, I want to show the image in imageview.
Image that is captured by camera successfully is shown in imageview but when I want to select it from gallery it does not show the image and it also does not show any error. It was working properly but later I add camera feature in activity, it's not working well.

selectedImage = BitmapFactory.decodeStream(imageStream);
You should check if selectedImage -the bitmap- is null.
I bet selectedImage==null.
This happens if the bitmap would become too big for available memory.
You should scale it down while loading from stream.
Remember: from the camera you only obtain a thumbnail. Thats the difference.

Here's my code to set a rounding photo from gallery or camera into ImageButton and it works perfectly :

Class variable not changing in IF or Switch statements

Seems simple, but I can't get it to work. I have a public class string variable that should change within a if or switch statement. I haven't declared the variable inside the statement so it should change given the scope, no? But it only reads "FROM" and when I do go to change it in the if statement that applies, it does change to "TO" but only in that instance and reverts back to "FROM". I would pass it along the methods, but the full code is more cluttered and I don't think it's possible to do so.

}

The reason the code keeps reverting is because the call to readImage() is in onActivityResult() which recreates the activity when called. So basically, you are getting a fresh object, and the onTypeText() is reinitialized. onActivityResult() is basically a callback from your previous activity.

Your onClick() is not being called due you don't assign clicklistener to R.id.faboptions_favorite and the other View
in onCreate add :
findViewById(R.id.faboptions_favorite).setOnClickListener(this);
and same for the other view.

This is what i have implemnted till now. But it doesn't give me the image back in the activity if it is stored in SD Card. Also the image is getting saved. Is is possible not to save the image in the storage media?
Thanks

A simple demo:
maim.xml
<button android:id="#+id/button1" android:layout_height="wrap_content" android:layout_width="match_parent" android:text="TakePhoto" button="">
<imageview android:id="#+id/imageView1" android:layout_gravity="center_horizontal" android:layout_height="wrap_content" android:layout_width="wrap_content"></imageview></button>

you need add permission
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE">
<uses-permission android:name="android.permission.CAMERA"> </uses-permission></uses-permission>
