Android: how to do automatic image center-crop to a specific size after photo taking

i'm having issue doing image center crop to a specific size after taking a still photo by calling MediaStore.ACTION_IMAGE_CAPTURE.
Action Image Capture currently stores the image to image directory, how do i crop image automatically according to my pre-set size and save it to the same path and filename?
appreciate if can give some guidance. im new to android
i do have the URI of the image, just wondering if there's any way to center crop, resize to a specific size eg: 456x456 and save the image to the same URI by overwriting.
below is my code under MainActivity:

File.createTempFile() adding random strings to file name

I am facing an issue which I do not understand. I am taking a picture then creating a PNG image file as per code that follows but somewhere down the line a random string is being added to the filename which causes me all sorts of issues. For example (as per tutorials I have found): I create an image called dimage_(generated timestamp) and save the string to shared preferences and the image in getExternalFilesDir(Environment.DIRECTORY_PICTURES). In shared preferences the string is correct but the file has the above mentioned string appended.
Eg:
The generated filename string saved in shared prefs:
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
<string name="driver_picture">dimage_20190610_065509</string>
</map>
Whereas the file checked with adb results as:
127|generic_x86:/storage/emulated/0/Android/data/africa.mykagovehicledrivers/files/Pictures $ ls
dimage_20190610_0655091215099619.png
generic_x86:/storage/emulated/0/Android/data/africa.mykagovehicledrivers/files /Pictures $
I have no clue where the 1215099619 extra part comes from!
This is the code of the activity:

As per code I am using String imageFileName; to save the path and then use it in the button click action to save it into shared preferences.
Thanks!

Found out the reasin. createTempFile does this. Switched to new File() and this solved the issue.

Camera is giving very big size image on device

In my project, I am capturing image from the camera. I am taking the full-size image from the app (instead of taking thumbnail). Captured image is of very big size which is 7 to 18 mb. When I have taken image from my default camera app, the size was roughly 2.5 mb only. As well as it's taking lot of time(6-10 seconds) to load and save to the folder. This happening only when I am using the android device, on emulator it's working good. This is my code:

Something you could do is download an available API online, or, if need be, dowload the source code of some online compressor. Then you could use it as a model. Never directly use the source code. One that is widely supported across languages is: https://optimus.keycdn.com/support/image-compression-api/

I am taking the image from the camera and getting the File. So, I am saving the image directly in file location which I generated using getOutputMediaFile() method. For that I am overloading saveImage() method like this:
private void saveImage(File mediaImage) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(mediaImage);
mediaScanIntent.setData(contentUri);
getContext().sendBroadcast(mediaScanIntent);
}
This method will put the image in the desired file location and also accessible to the Gallery for other apps. This method is same as galleryAddPic() method on this link Taking Photos Simply
But In the case of picking a photo from the Gallery, I will have to create the File in the desired location and write the bytes of the picked image into that file, so the old saveImage() method will not change.
In onActivityResult method, this is how I used overloaded saveImage() method:
else if (requestCode == CAMERA) {
saveImage(imageFile);
Bitmap bitmap = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
loadImage.setImageBitmap(bitmap);
Toast.makeText(getContext(), MESSAGE_IMAGE_SAVED, Toast.LENGTH_SHORT).show();
imageTextMessage.setVisibility(View.INVISIBLE);
}

How to save picture to gallery in Android [duplicate]

This question already has an answer here:
Android camera Intent not saving in gallery [duplicate]
(1 answer)
Closed 5 years ago.
I am new to programming and especially Android. I am making a simple application where I am invoking the camera and taking a picture, the picture is then displayed in an ImageView but I also want it to be stored in the gallery when I click the button to view the stored pictures.
My Code:
package com.example.picture.app;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageView;
import java.io.File;
public class MainActivity extends AppCompatActivity {
public static final int CAMERA_REQUEST = 10;
private ImageView imgView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//get access to the image view
imgView = findViewById(R.id.imgView);
}
//this method will be called when the take photo button is clicked
public void btnTakePhotoClicked(View v) {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
public void onImageGalleryClicked(View v) {
//invoke the image gallery using n implicit intent
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
//where do we want to find the data
File pictureDirectory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
String pictureDirectoryPath = pictureDirectory.getPath();
//get a uri representation
Uri data = Uri.parse(pictureDirectoryPath);
//set the data and the type. Get all image types
photoPickerIntent.setDataAndType(data, "image/*");
startActivityForResult(photoPickerIntent, 20);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//DID THE USER CHOOSE OK? If so code inside this code will execute
if (resultCode == RESULT_OK) {
if (requestCode == CAMERA_REQUEST) {
//WE ARE HEARING BACK FROM THE CAMERA
Bitmap cameraImage = (Bitmap) data.getExtras().get("data");
//at this point we have the image from the camera
imgView.setImageBitmap(cameraImage);
}
}
}

You can use the compress() method to save it in External storage.
You can try this
try
{
FileOutputStream out = new FileOutputStream(new File(Environment.getExternalStorageDirectory().toString() + "/bmp.png"));
cameraImage.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
catch (Exception e)
{
Toast.makeText(getBaseContext(),e.getMessage(), Toast.LENGTH_SHORT);
}
Also, you have to add uses permission <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

I am new to android.In my app ,i need to set picture from camera or gallery so i used this code(mentioned). gallery option is working fine but when i choose camera ,the app is unfortunately stopped,please help to fix it and i also save the picture in gallery which was taken in camera.

If you are having problem with the image from camera then you can use the following function.
public void fromCamera(){
String path= Environment.getExternalStorageDirectory().getPath() + "/DCIM/Camera/";
File file = new File(path,"IMG_"+System.currentTimeMillis()+".jpg");
file.getParentFile().mkdirs();
try {
file.createNewFile();
}catch (IOException e) {
e.printStackTrace();
}
mPicCaptureUri = Uri.fromFile(file);
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mPicCaptureUri);
startActivityForResult(intent, REQUEST_CAMERA);
}
And on your OnActivityResult you can get your image and do what you need to do:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
if(requestCode == REQUEST_CAMERA){
if(mPicCaptureUri!=null){
//do try to set image here ....
}
}
}
}
And yes do define at the top mPicCaptureUri as:
private Uri mPicCaptureUri = null;
It worked for me .. hope it helps..
