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"/>

ImageView not showing captured photo android

I am new in android development. I have been trying to access the camera, capture a photo, and then return to my activity and show it on an ImageView.
Here is the code of my activity (very simple, it just do that)
public class Profile extends Activity {
private static final int CAMERA_REQUEST = 1337;
private ImageView imagePhoto;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
imagePhoto = (ImageView) findViewById(R.id.imagePhoto);
ImageView photoButton = (ImageView) this.findViewById(R.id.camera);
photoButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if( requestCode == CAMERA_REQUEST)
{
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image =(ImageView) findViewById(R.id.imagePhoto);
image.setImageBitmap(thumbnail);
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
What I am doing wrong? I search and try so many codes. When I click in the button, the camera shows up, I take a photo, and then I return to the activity but the thumbnail of the photo is not showing in the ImageView "imagePhoto".
Here is the layout for the imagePhoto:
<ImageView
android:id="#+id/imagePhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/welcome"
android:layout_marginRight="50dp"
android:layout_marginTop="82dp"
android:layout_toLeftOf="#+id/camera"
android:src="#drawable/add_photo" /> `/* It has another photo, because I was trying to see if it changes */
And this is in my manifest also:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
I tried so many codes! Thanks in advance. I'm using a Samsung device.

Your Code Looks Fine but i want to share mine as it is working for me
This code will also create a folder in your memory and save the image there
here is the code
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Random;
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.Bitmap.CompressFormat;
import android.os.Bundle;
import android.os.Environment;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;
public class MainActivity extends ActionBarActivity {
ImageView image;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image =(ImageView) findViewById(R.id.imagePhoto);
// create external folder
createFolder();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1888);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1888 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
image.setImageBitmap(photo );
// to create a random image file name
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
String filePath = "/sdcard/PictureFolder/"+fname;
FileOutputStream fileOutputStream = null;
try {
fileOutputStream = new FileOutputStream(filePath);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
//choose another format if PNG doesn't suit you
photo.compress(CompressFormat.PNG, 100, bos);
try {
bos.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
bos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public void createFolder()
{
String RootDir = Environment.getExternalStorageDirectory()
+ File.separator + "PictureFolder";
File RootFile = new File(RootDir);
RootFile.mkdir();
}
}
and only i add this permission
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Taking a picture via camera intent in Android

I am using the following code for clicking a photo on Button click.
package com.example.clickpic;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
int TAKE_PHOTO_CODE = 0;
public static int count=0;
private ImageView imageView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//here,we are making a folder named picFolder to store pics taken by the camera using this application
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolder/";
File newdir = new File(dir);
newdir.mkdirs();
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button capture = (Button) findViewById(R.id.btnCapture);
capture.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// here,counter will be incremented each time,and the picture taken by camera will be stored as 1.jpg,2.jpg and likewise.
count++;
String file = dir+count+".jpg";
File newfile = new File(file);
try {
newfile.createNewFile();
} catch (IOException e) {}
Uri outputFileUri = Uri.fromFile(newfile);
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 1888);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1888 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
}
The code works perfectly well but it just opens up the camera activity. What must I do so that on button click, it clicks a picture and saves it as well?
Right now, this just opens the camera app of the phone, and expects me to click the picture and click on OK. I don't want these things.
All I want is, when I click on the button from my app it should click a picture without expecting any additional input from me.
Edit
I have already tried to create a camera app of my own, but I ran into some issues.
That's why I am trying this approach. Camera API not working on KITKAT

All I want is, when I click on the button from my app it should click a picture without expecting any additional input from me. -
Its not achieved by Camera Intent like android.provider.MediaStore.ACTION_IMAGE_CAPTURE. You have to implement camera interface portion in your code without using native camera application of Device.
Look at portion of Building Camera App

I have written a camera class which takes picture, arranges the orientation (some devices takes photo horizontal as default) and saves the photo taken. You can check it from the link below:
Camera capture orientation on samsung devices in android
Edit: Sorry, savePhoto functions are not written in my example. Adding them now.
savePhoto function:
public void savePhoto(Bitmap bmp) {
imageFileFolder = new File(Environment.getExternalStorageDirectory(),
cc.getDirectoryName());
imageFileFolder.mkdir();
FileOutputStream out = null;
Calendar c = Calendar.getInstance();
String date = fromInt(c.get(Calendar.MONTH))
+ fromInt(c.get(Calendar.DAY_OF_MONTH))
+ fromInt(c.get(Calendar.YEAR))
+ fromInt(c.get(Calendar.HOUR_OF_DAY))
+ fromInt(c.get(Calendar.MINUTE))
+ fromInt(c.get(Calendar.SECOND));
imageFileName = new File(imageFileFolder, date.toString() + ".jpg");
try {
out = new FileOutputStream(imageFileName);
bmp.compress(Bitmap.CompressFormat.JPEG, 70, out);
out.flush();
out.close();
scanPhoto(imageFileName.toString());
out = null;
} catch (Exception e) {
e.printStackTrace();
}
}
scanPhoto function:
public void scanPhoto(final String imageFileName) {
geniusPath = imageFileName;
msConn = new MediaScannerConnection(MyClass.this,
new MediaScannerConnectionClient() {
public void onMediaScannerConnected() {
msConn.scanFile(imageFileName, null);
}
#Override
public void onScanCompleted(String path, Uri uri) {
msConn.disconnect();
}
});
msConn.connect();
}
SavePhotoTask class:
class SavePhotoTask extends AsyncTask<byte[], String, String> {
#Override
protected String doInBackground(byte[]... jpeg) {
File photo = new File(Environment.getExternalStorageDirectory(),
"photo.jpg");
if (photo.exists()) {
photo.delete();
}
try {
FileOutputStream fos = new FileOutputStream(photo.getPath());
fos.write(jpeg[0]);
fos.close();
} catch (java.io.IOException e) {
}
return (null);
}
}

Problems when loading cameraimages in imageView

When I take a picture, the picture will saved on the SD.(This works very well)
But the picture won´t shows in the imageView. Do you have any idea?

In the manifest I have are the following:
uses-feature android:name="android.hardware.camera" android:required="false"
uses-permission android:name="android.permission.CAMERA"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

Here I have this peace of code that works fine the first function open the camera and take the picture and the second one place the image you took into an image view...
public void takePictu(View view) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == CAMERA_REQUEST && resultCode == RESULT_OK){
photo3 = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo3);
imageView.buildDrawingCache();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
photo3.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object
byte[] b = baos.toByteArray();
encodedImage = android.util.Base64.encodeToString(b, android.util.Base64.DEFAULT);
}
}
