Capturing a picture and than displaying within an ImageView - Android - android

Hey guys I am using my webcam to simulate a camera in the emulator and when I go to take the picture and select the check mark button to use the picture I run across an error while trying to display the image back into my ImageView on the app.
Here is my code:
Initiator:
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
function....
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
if (resultCode == RESULT_OK) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
Bitmap bm = BitmapFactory.decodeFile(imagePath);
Log.w("Here","error");
Bitmap bm = BitmapFactory.decodeFile(imagePath);
ImageView image = (ImageView) findViewById(R.id.gimg1);
image.setImageBitmap(bm);
} else if (resultCode == RESULT_CANCELED){
}
}
}
I run across a runtime error
Suggestions and thoughts are needed!

You can use the following codes. It's fully functional and allows you set image from both your camera and gallery as well. I am almost sure that your runtime error is "OutOfMemoryError: bitmap size exceeds VM budget" as I am seeing that you have loaded the captured image directly to your imageView. You should scale it , please take a look at the method called GetScaledBitmap in my following code. Hope your codes will work ok if you use that method only when you load the image to your imageview. Full example is done for you , Hope it helps.

You were calling data.getData() whereas it should have been data.getExtra("data") as data is an intent which you will have put the bitmap

Very Simple way to Click button and set store image in imageview.
`public class MainActivity extends Activity {

Toast.makeText(this, "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
break;
default:

}
Here is a example how to get/create a thumbnail from a video:
public static String getThumbnailPathForLocalFile(Context context, Uri fileUri) {
long fileId = getFileId(context, fileUri);
MediaStore.Video.Thumbnails.getThumbnail(context.getContentResolver(), fileId, 3, null);
Cursor thumbCursor = context.getContentResolver().query(MediaStore.Video.Thumbnails.EXTERNAL_CONTENT_URI, thumbColumns, "video_id = " + fileId, null, null);
if (thumbCursor.moveToFirst()) {
return thumbCursor.getString(thumbCursor.getColumnIndex("_data"));
}
return null;
}
public static long getFileId(Context context, Uri fileUri) {
Cursor cursor = context.getContentResolver().query(fileUri, mediaColumns, null, null, null);
if (cursor.moveToFirst()) {
return (long) cursor.getInt(cursor.getColumnIndexOrThrow(SQLiteHelper._ID));
}
return 0;
}
then in onActivityResult:
String thumbPathString = getThumbnailPathForLocalFile(this, data.getData());
imageView.setImageURI(Uri.parse(thumbPathString));
I hope this helps you.
I haven't tested this because thumbnail path is stored in SQLite..

open camera using intent

I want to use intent to open camera in Android .
I used the following code but when i press the button (whose action is onclick() function the app closes on itself .

}
}
try this code
public static final int CAMERA_PIC_REQUEST = 1;//firstly define this
Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(photo, CAMERA_PIC_REQUEST);
The parameter passed to an "on-click" method is of type View not int as you show.
According to this tutorial your onClick method should be as follows:
public void onclick( View v ){
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
}
Where CAMERA_PIC_REQUEST is defined as (although I'm not quite sure why you would need to statically hard-code this value in your application):
private static final int CAMERA_PIC_REQUEST = 1337;
Update
CAMERA_PIC_REQUEST is used to uniquely identify the result being returned to onActivityResult. Multiple startActivityForResultrequests could be outstanding at one time.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
if (resultCode == RESULT_OK) {
tv.setText("Got picture!");
imageData = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.imageView1);
image.setImageBitmap(imageData);
} else if (resultCode == RESULT_CANCELED){
tv.setText("Cancelled");
}
}
}
please have a look at this code, this is working fine with me
//define the file-name to save photo taken by Camera activity
fileName = "new-photo-name.jpg";
//create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
also apply this method to read image when you taken the image from camera.
//handling intent responses
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK)
try {
if (bitmap != null) {bitmap.recycle();}
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(imageUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
imageUriString = cursor.getString(column_index);
getContentResolver().notifyChange(imageUri, null);
ContentResolver cr = getContentResolver();
try {
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
imageButtonPictureShop.setImageBitmap(bitmap);
// this.uploadImage();
this.executeMultipartPost();
// this.uploadFile(imageUriString);
}
catch (Exception e)
{
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
if(e.getMessage() != null)Log.e("Exception" , e.getMessage());
else Log.e("Exception" , "Exception");
e.printStackTrace();
}
}
catch (Exception e)
{
if(e.getMessage() != null)Log.e("Exception" , e.getMessage());
else Log.e("Exception" , "Exception");
e.printStackTrace();
}
super.onActivityResult(requestCode, resultCode, data);
}
I know this question old and answered, but for those who are asking how to get the image file ?
heres the solution.
String ExternalStorageDirectoryPath = Environment.getExternalStorageDirectory().getAbsolutePath();
String targetPath = ExternalStorageDirectoryPath + "/DCIM/Camera";
File targetDirector = new File(targetPath);
File[] files = targetDirector.listFiles()
String ImagePath = files[ file.files-1 ].getAbsolutePath();
Bitmap bmp = BitmapFactory.decodeFile(pathName);
ivImage.setImageBitmap( bmp );
Also you don't need to add Camera permissions on your Manifest file.
-Cheers and vote up if this help you
-Happy Codings..
It's very easy to start camera from your Android app:
just write two lines code in onClick method
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_PIC_REQUEST );
Add one constant field in your class (you can use any random number instead of 7)
private int CAMERA_PIC_REQUEST = 7;
After a lot of research I found this solution. Just to make things clear I created an entire app for this question which serves the purpose of opening the camera clicking a photo and setting the image as the ImageBitmap of an ImageView. The code asked in this question starts at the second block i.e. the setView() method which is below the onCreate() method following which we have the onActivityResult() method
Here is a demo of the app.
Below I have Attached the MainActivity.java file
package com.cr7.opencamera;
import android.Manifest;
import android.app.Activity;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.util.Log;
import android.widget.Button;
import android.widget.ImageView;
import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
private Button buttonCaptureImageFromCamera;
private Uri imageUri;
private ImageView imageViewCameraImage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Button that will open the camera
buttonCaptureImageFromCamera = findViewById(R.id.buttonCaptureImageFromCamera);
// ImageView that will store the image
imageViewCameraImage = findViewById(R.id.imageViewCameraImage);
askPermission();
}
Here imageUri is a global variable so that it can be used in the onActivityResult() method
// Sets OnClickListener for the button if storage permission is given
private void setView() {
buttonCaptureImageFromCamera.setOnClickListener(v -> {
String fileName = "new-photo-name.jpg";
// Create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION, "Image capture by camera");
imageUri =
getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, 1231);
});
}
This is the onActivityResult method. Here I've used imageUri i.e. the global variable of type Uri which was initialized in the OnClickListener of the button in the setView() method above.
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1231 && resultCode == Activity.RESULT_OK) {
try {
ContentResolver cr = getContentResolver();
try {
// Creating a Bitmap with the image Captured
Bitmap bitmap = MediaStore.Images.Media.getBitmap(cr, imageUri);
// Setting the bitmap as the image of the
imageViewCameraImage.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
} catch (IllegalArgumentException e) {
if (e.getMessage() != null)
Log.e("Exception", e.getMessage());
else
Log.e("Exception", "Exception");
e.printStackTrace();
}
}
}
Remaining code...
// Asking user for storage permission
public void askPermission() {
// Checking if the permissions are not granted.
if (
ContextCompat.checkSelfPermission(
this,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE
) != PackageManager.PERMISSION_GRANTED ||
ContextCompat.checkSelfPermission(
this,
android.Manifest.permission.READ_EXTERNAL_STORAGE
) != PackageManager.PERMISSION_GRANTED
) {
// If not granted requesting Read and Write storage
ActivityCompat.requestPermissions(this, /*You can ask for multiple request by adding
more permissions to the string*/new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE}, 60);
} else {
// If permissions are granted we proceed by setting an OnClickListener for the button
// which helps the user pick the image
setView();
}
}
// This method is called after the permissions have been asked i.e. the dialog that says
// allow or deny
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
// Now by default we assume that the permission has not been granted
boolean allPermissionsGranted = false;
// Now we check if the permission was granted
if ( requestCode == 60 && grantResults.length > 0) {
// If all the permissions are granted allPermissionsGranted is set to true else false
allPermissionsGranted = grantResults[0] == PackageManager.PERMISSION_GRANTED
&&
grantResults[1] == PackageManager.PERMISSION_GRANTED;
}
// If permissions are granted we call the setView Method which prompts the user to pick
// an Image either by the clicking it now or picking from the gallery
if ( allPermissionsGranted ) {
setView();
}
}
}
These blocks of code are in sequence i.e. if you merge all these blocks you get the complete MainActivity.java class.
If you wan to Implement this app you need yo create a layout file with an ImageView with an id "imageViewCameraImage"and a button with an id "buttonCaptureImageFromCamera".
Hope this helps. I know this is long and I'm making it longer by writing this.
Regards,
Joel

Capture Image from Camera and Display in Activity

I want to write a module where on a click of a button the camera opens and I can click and capture an image. If I don't like the image I can delete it and click one more image and then select the image and it should return back and display that image in the activity.
Here's an example activity that will launch the camera app and then retrieve the image and display it.
package edu.gvsu.cis.masl.camerademo;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MyCameraActivity extends Activity {
private static final int CAMERA_REQUEST = 1888;
private ImageView imageView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.imageView = (ImageView)this.findViewById(R.id.imageView1);
Button photoButton = (Button) this.findViewById(R.id.button1);
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) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
}
Note that the camera app itself gives you the ability to review/retake the image, and once an image is accepted, the activity displays it.
Here is the layout that the above activity uses. It is simply a LinearLayout containing a Button with id button1 and an ImageView with id imageview1:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button android:id="#+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="#string/photo"></Button>
<ImageView android:id="#+id/imageView1" android:layout_height="wrap_content" android:src="#drawable/icon" android:layout_width="wrap_content"></ImageView>
</LinearLayout>
And one final detail, be sure to add:
<uses-feature android:name="android.hardware.camera"></uses-feature>
and if camera is optional to your app functionality. make sure to set require to false in the permission. like this
<uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature>
to your manifest.xml.
Update (2020)
Google has added a new ActivityResultRegistry API that "lets you handle the startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows" - source.
The API was added in androidx.activity 1.2.0-alpha02 and androidx.fragment 1.3.0-alpha02.
So you are now able to do something like:
val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { success: Boolean ->
if (success) {
// The image was saved into the given Uri -> do something with it
}
}
val imageUri: Uri = ...
button.setOnClickListener {
takePicture.launch(imageUri)
}
Take a look at the documentation to learn how to use the new Activity result API: https://developer.android.com/training/basics/intents/result#kotlin
There are many built-in ActivityResultContracts that allow you to do different things like pick contacts, request permissions, take pictures or take videos. You are probably interested in the ActivityResultContracts.TakePicture shown above.
Note that androidx.fragment 1.3.0-alpha04 deprecates the startActivityForResult() + onActivityResult() and requestPermissions() + onRequestPermissionsResult() APIs on Fragment. Hence it seems that ActivityResultContracts is the new way to do things from now on.
Original answer (2015)
It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.
Request this permission on the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
On your Activity, start by defining this:
static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;
Then fire this Intent in an onClick:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
Log.i(TAG, "IOException");
}
// Continue only if the File was successfully created
if (photoFile != null) {
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
}
}
Add the following support method:
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, // prefix
".jpg", // suffix
storageDir // directory
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
Then receive the result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
try {
mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
mImageView.setImageBitmap(mImageBitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.

I know it's a quite old thread, but all these solutions are not completed and don't work on some devices when user rotates camera because data in onActivityResult is null. So here is solution which I have tested on lots of devices and haven't faced any problem so far.
First declare your Uri variable in your activity:
private Uri uriFilePath;
Then create your temporary folder for storing captured image and make intent for capturing image by camera:
PackageManager packageManager = getActivity().getPackageManager();
if (packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
File mainDirectory = new File(Environment.getExternalStorageDirectory(), "MyFolder/tmp");
if (!mainDirectory.exists())
mainDirectory.mkdirs();
Calendar calendar = Calendar.getInstance();
uriFilePath = Uri.fromFile(new File(mainDirectory, "IMG_" + calendar.getTimeInMillis()));
intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uriFilePath);
startActivityForResult(intent, 1);
}
And now here comes one of the most important things, you have to save your uriFilePath in onSaveInstanceState, because if you didn't do that and user rotated his device while using camera, your uri would be null.
#Override
protected void onSaveInstanceState(Bundle outState) {
if (uriFilePath != null)
outState.putString("uri_file_path", uriFilePath.toString());
super.onSaveInstanceState(outState);
}
After that you should always recover your uri in your onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
if (uriFilePath == null && savedInstanceState.getString("uri_file_path") != null) {
uriFilePath = Uri.parse(savedInstanceState.getString("uri_file_path"));
}
}
}
And here comes last part to get your Uri in onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
String filePath = uriFilePath.getPath(); // Here is path of your captured image, so you can create bitmap from it, etc.
}
}
}
P.S. Don't forget to add permissions for Camera and Ext. storage writing to your Manifest.
Here you can open camera or gallery and set the selected image into imageview
private static final String IMAGE_DIRECTORY = "/YourDirectName";
private Context mContext;
private CircleImageView circleImageView; // imageview
private int GALLERY = 1, CAMERA = 2;
Add permissions in manifest
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="ANDROID.PERMISSION.READ_EXTERNAL_STORAGE" />
In onCreate()
requestMultiplePermissions(); // check permission
circleImageView = findViewById(R.id.profile_image);
circleImageView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showPictureDialog();
}
});
Show options dialog box (to select image from camera or gallery)
private void showPictureDialog() {
AlertDialog.Builder pictureDialog = new AlertDialog.Builder(this);
pictureDialog.setTitle("Select Action");
String[] pictureDialogItems = {"Select photo from gallery", "Capture photo from camera"};
pictureDialog.setItems(pictureDialogItems,
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case 0:
choosePhotoFromGallary();
break;
case 1:
takePhotoFromCamera();
break;
}
}
});
pictureDialog.show();
}
Get photo from Gallery
public void choosePhotoFromGallary() {
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, GALLERY);
}
Get photo from Camera
private void takePhotoFromCamera() {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA);
}
Once the image is get selected or captured then ,
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == this.RESULT_CANCELED) {
return;
}
if (requestCode == GALLERY) {
if (data != null) {
Uri contentURI = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), contentURI);
String path = saveImage(bitmap);
Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
circleImageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(), "Failed!", Toast.LENGTH_SHORT).show();
}
}
} else if (requestCode == CAMERA) {
Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
circleImageView.setImageBitmap(thumbnail);
saveImage(thumbnail);
Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show();
}
}
Now its time to store the picture
public String saveImage(Bitmap myBitmap) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File wallpaperDirectory = new File(Environment.getExternalStorageDirectory() + IMAGE_DIRECTORY);
if (!wallpaperDirectory.exists()) { // have the object build the directory structure, if needed.
wallpaperDirectory.mkdirs();
}
try {
File f = new File(wallpaperDirectory, Calendar.getInstance().getTimeInMillis() + ".jpg");
f.createNewFile();
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());
MediaScannerConnection.scanFile(this,
new String[]{f.getPath()},
new String[]{"image/jpeg"}, null);
fo.close();
Log.d("TAG", "File Saved::--->" + f.getAbsolutePath());
return f.getAbsolutePath();
} catch (IOException e1) {
e1.printStackTrace();
}
return "";
}
Request permission
private void requestMultiplePermissions() {
Dexter.withActivity(this)
.withPermissions(
Manifest.permission.CAMERA,
Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE)
.withListener(new MultiplePermissionsListener() {
#Override
public void onPermissionsChecked(MultiplePermissionsReport report) {
if (report.areAllPermissionsGranted()) { // check if all permissions are granted
Toast.makeText(getApplicationContext(), "All permissions are granted by user!", Toast.LENGTH_SHORT).show();
}
if (report.isAnyPermissionPermanentlyDenied()) { // check for permanent denial of any permission
// show alert dialog navigating to Settings
//openSettingsDialog();
}
}
#Override
public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
token.continuePermissionRequest();
}
}).
withErrorListener(new PermissionRequestErrorListener() {
#Override
public void onError(DexterError error) {
Toast.makeText(getApplicationContext(), "Some Error! ", Toast.LENGTH_SHORT).show();
}
})
.onSameThread()
.check();
}
You need to read up about the Camera. (I think to do what you want, you'd have to save the current image to your app, do the select/delete there, and then recall the camera to try again, rather than doing the retry directly inside the camera.)
Here is code I have used for Capturing and Saving Camera Image then display it to imageview. You can use according to your need.
You have to save Camera image to specific location then fetch from that location then convert it to byte-array.
Here is method for opening capturing camera image activity.
private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;
private void captureCameraImage() {
Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(Environment.getExternalStorageDirectory(), "POST_IMAGE.jpg");
chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
imageToUploadUri = Uri.fromFile(f);
startActivityForResult(chooserIntent, CAMERA_PHOTO);
}
then your onActivityResult() method should be like this.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_PHOTO && resultCode == Activity.RESULT_OK) {
if(imageToUploadUri != null){
Uri selectedImage = imageToUploadUri;
getContentResolver().notifyChange(selectedImage, null);
Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
if(reducedSizeBitmap != null){
ImgPhoto.setImageBitmap(reducedSizeBitmap);
Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
uploadImageButton.setVisibility(View.VISIBLE);
}else{
Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}else{
Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
}
}
}
Here is getBitmap() method used in onActivityResult(). I have done all performance improvement that can be possible while getting camera capture image bitmap.
private Bitmap getBitmap(String path) {
Uri uri = Uri.fromFile(new File(path));
InputStream in = null;
try {
final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
in = getContentResolver().openInputStream(uri);
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(in, null, o);
in.close();
int scale = 1;
while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
IMAGE_MAX_SIZE) {
scale++;
}
Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);
Bitmap b = null;
in = getContentResolver().openInputStream(uri);
if (scale > 1) {
scale--;
// scale to max possible inSampleSize that still yields an image
// larger than target
o = new BitmapFactory.Options();
o.inSampleSize = scale;
b = BitmapFactory.decodeStream(in, null, o);
// resize to desired dimensions
int height = b.getHeight();
int width = b.getWidth();
Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);
double y = Math.sqrt(IMAGE_MAX_SIZE
/ (((double) width) / height));
double x = (y / height) * width;
Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
(int) y, true);
b.recycle();
b = scaledBitmap;
System.gc();
} else {
b = BitmapFactory.decodeStream(in);
}
in.close();
Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
b.getHeight());
return b;
} catch (IOException e) {
Log.e("", e.getMessage(), e);
return null;
}
}
Hope it helps!

Add these permission in Androidmenifest.xml file
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CAMERA"/>
I created a dialog with the option to choose Image from gallery or camera.
with a callback as
Uri if the image is from the gallery
String as a file path if the image is captured from the camera.
Image as File the image chosen from camera needs to be uploaded on the internet as Multipart file data
At first we to define permission in AndroidManifest as we need to write external store while creating a file and reading images from gallery
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Create a file_paths xml in
app/src/main/res/xml/file_paths.xml
with path
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Then we need to define file provier to generate Content uri to access file stored in external storage
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">

Call in Activity or fragment like this
Define ImagePicker in Fragment/Activity

As others have discussed, using data.getExtras().get("data") will just get the low-quality thumbnail.
The solution is to pass a location with your ACTION_IMAGE_CAPTURE intent telling the camera where to store the full quality image.
The code is Kotlin and does not need any permissions.
val f = File("${getExternalFilesDir(null)}/imgShot")
val photoURI = FileProvider.getUriForFile(this, "${packageName}.fileprovider", f)
val intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
.apply { putExtra(MediaStore.EXTRA_OUTPUT, photoURI) }
startActivityForResult(intent, 1234)
Then handle the result after the picture was taken:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == 1234 && resultCode == Activity.RESULT_OK) {
val bitmap = BitmapFactory.decodeFile(
File("${getExternalFilesDir(null)}/imgShot").toString()
)
// use imageView.setImageBitmap(bitmap) or whatever
}
}
You will also need to add an external FileProvider as described here. AndroidManifest.xml:
<manifest>
<application>
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provide_paths" />
</provider>
</application>
</manifest>
Add a new file app/src/main/res/xml/provide_paths.xml:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="." />
</paths>
Lastly you should replace 1234 with your own logic for keeping track of request code (usually an enum with a member such as RequestCode.CAPTURE_IMAGE)
You can use this code to onClick listener (you can use ImageView or button)
image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, 1);
}
}
});
To display in your imageView
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
bitmap = (Bitmap) extras.get("data");
image.setImageBitmap(bitmap);
}
}
Note: Insert this to the manifest
<uses-feature android:name="android.hardware.camera" android:required="true" />
You can use custom camera with thumbnail image.
You can look my project.
Here is the complete code:
package com.example.cameraa;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
Button btnTackPic;
Uri photoPath;
ImageView ivThumbnailPhoto;
static int TAKE_PICTURE = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Get reference to views
btnTackPic = (Button) findViewById(R.id.bt1);
ivThumbnailPhoto = (ImageView) findViewById(R.id.imageView1);
btnTackPic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, TAKE_PICTURE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap)intent.getExtras().get("data");
ivThumbnailPhoto.setImageBitmap(photo);
ivThumbnailPhoto.setVisibility(View.VISIBLE);
}
}
}
Remember to add permissions for the camera too.
2021 May, JAVA
after handling necessary Permissions described next to this post,
in manifest add:
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
android:name="android.hardware.camera"
android:required="true" />
....
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths" />
</provider>
....
where ${applicationId} is app's package name , e.g. my.app.com.
In res->xml->provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path name="my_images" path="Pictures" />
<external-path name="external_files" path="."/>
<files-path
name="files" path="." />
<external-cache-path
name="images" path="." />
</paths>
in Activity:
private void onClickCaptureButton(View view) {
Intent takePictureIntent_ = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent_.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile_ = null;
try {
photoFile_ = createImageFile();
} catch (IOException ex) {
}
if(photoFile_!=null){
picturePath=photoFile_.getAbsolutePath();
}
// Continue only if the File was successfully created
if (photoFile_ != null) {
Uri photoURI_ = FileProvider.getUriForFile(this,
"my.app.com.fileprovider", photoFile_);
takePictureIntent_.putExtra(MediaStore.EXTRA_OUTPUT, photoURI_);
startActivityForResult(takePictureIntent_, REQUEST_IMAGE_CAPTURE);
}
}
}
And three more moves:
...
private static String picturePath;
private static final int REQUEST_IMAGE_CAPTURE = 2;
...
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp_ = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new
Date());
String imageFileName_ = "JPEG_" + timeStamp_ + "_";
File storageDir_ = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image_ = File.createTempFile(
imageFileName_, /* prefix */
".jpg", /* suffix */
storageDir_ /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
picturePath= image_.getAbsolutePath();
return image_;
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == REQUEST_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK
){
try {
File file_ = new File(picturePath);
Uri uri_ = FileProvider.getUriForFile(this,
"my.app.com.fileprovider", file_);
rasm.setImageURI(uri_);
} catch (/*IO*/Exception e) {
e.printStackTrace();
}
}
}
and
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putString("safar", picturePath);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}
and:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
picturePath = savedInstanceState.getString("safar");
}
....
}
Bitmap photo = (Bitmap) data.getExtras().get("data"); gets a thumbnail from camera. There is an article about how to store a picture in external storage from camera.
useful link
Please, follow this example with this implementation by using Kotlin and Andoirdx support:
button1.setOnClickListener{
file = getPhotoFile()
val uri: Uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
captureImage.putExtra(MediaStore.EXTRA_OUTPUT, uri)
val camaraActivities: List<ResolveInfo> = applicationContext.getPackageManager().queryIntentActivities(captureImage, PackageManager.MATCH_DEFAULT_ONLY)
for (activity in camaraActivities) {
applicationContext.grantUriPermission(activity.activityInfo.packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
}
startActivityForResult(captureImage, REQUEST_PHOTO)
}
And the activity result:
if (requestCode == REQUEST_PHOTO) {
val uri = FileProvider.getUriForFile(applicationContext, "com.example.foto_2.filrprovider", file!!)
applicationContext.revokeUriPermission(uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
imageView1.viewTreeObserver.addOnGlobalLayoutListener {
width = imageView1.width
height = imageView1.height
imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
}
if(width!=0&&height!=0){
imageView1.setImageBitmap(getScaleBitmap(file!!.path , width , height))
}else{
val size = Point()
this.windowManager.defaultDisplay.getSize(size)
imageView1.setImageBitmap(getScaleBitmap(file!!.path , size.x , size.y))
}
}
You can get more detail in https://github.com/joelmmx/take_photo_kotlin.git
I hope it helps you!
Use the following code to capture picture using your mobile camera.
If you are using android having version higher than Lolipop, You should add the permission request also.
private void cameraIntent()
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);
}
#override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
}
}
Bad quality
From my experience if we use
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, RESULT_ADD_PHOTO);
And handle in onActivityResult() with
Bitmap thumbnail= (Bitmap) data.getExtras().get("data");
It will give you thumbnail only and of course have a bad quality.
Nice quality
You can show camera and save your image file in public directory, example in Document directory
Use this in your onClick()
String imagePath = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS) +
File.separator + "your_image_name.jpeg";
Intent i =new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageFile = new File(imagePath );
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile));
startActivityForResult(i, RESULT_ADD_PHOTO);
And in onActivityResult()
Bitmap imageBitmap1 = BitmapFactory.decodeFile(imageFile.getAbsolutePath());
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap imageBitmap = Bitmap.createBitmap(imageBitmap1, 0, 0, imageBitmap1.getWidth(), imageBitmap1.getHeight(), matrix, true);
binding.imageView.setImageBitmap(imageBitmap);
I use postRotate() because in my code, image result rotate to left so I need to rotate it 90

Image sd card path from intent gallery

I am starting gallery through intent otherwise its giving problem to display gallery in grid view.
But i want the actual sd card path of the image i am selection from the gallery, opened by intent.
here is the code..
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/jpg");
photoPickerIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Pictures/image.jpg"));
startActivityForResult(photoPickerIntent, 1);
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == RESULT_CANCELED) {
showToast(this,"Activity cancelled");
return;
}
else if(resultCode == RESULT_OK) {
System.out.println("requestCode--"+requestCode);
System.out.println("resultCode--"+resultCode);
System.out.println("data--"+intent.getData());
Uri uri = intent.getData();
String data = uri.getPath();
System.out.println("uri.getPath()--"+uri.getPath());
System.out.println("type--"+intent.getType());
System.out.println("path--"+Environment.getExternalStorageState());
return;
}
switch (requestCode) {
case CAMERA_ACTIVITY:
Bundle b = intent.getExtras();
Bitmap bm = (Bitmap) b.get("data");
// mImageView.setImageBitmap(bm); // Display image in the View
// large image?
if (b.containsKey(MediaStore.EXTRA_OUTPUT)) { // large image?
Log.i(TAG, "This is a large image");
showToast(this,"Large image");
// Should have to do nothing for big images -- should already saved in MediaStore ... but
MediaStore.Images.Media.insertImage(getContentResolver(), bm, null, null);
}
else {
Log.i(TAG, "This is a small image");
showToast(this,"Small image");
MediaStore.Images.Media.insertImage(getContentResolver(), bm, null, null);
}
break;
}
}
}
I am getting all data from intent object. But i want the sd card path for the image what i am selecting to upload that image in server..
how do i get that?
You may want something like this:
Uri uri = (Uri) intent.getExtras().get("android.intent.extra.STREAM");
if ( intent.getAction().equals( Intent.ACTION_SEND ) )
{
if ( uri.getScheme().equals("content"))
{
Cursor cursor = getContentResolver().query( uri, null, null, null, null );
cursor.moveToFirst();
filePath = cursor.getString(cursor.getColumnIndexOrThrow(Images.Media.DATA));
}
}

This code will pop up one Dialog Box with Camera and gallery and devices SD card to get the images path.

How to receive multiple gallery results in onActivityResult

I want to start the gallery via intent and want to get the results in my onActivityResult method.
All works fine if i click on one pic.
The question ive got now is, how do i get the results, if i choose more than one picture in the gallery?
If found hcpl´s code, which does it for one picture:
public class BrowsePicture extends Activity {
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
You need to store that image path into array string then retrieve it according to your requirement.
Here is a sample code which will Pop up one Dialog box with 3 selection criteria like camera, Gallery, Device.
This may help you.
