I am developing an android app where user is selecting the image either from gallery or capture from camera. When user get the image from gallery i get the image uri then i pass this uri to other activity in string form. then in next activity i convert that string into uri and then uri into bitmap and set the image bitmap in imageview. Now when i capture the image from camera i get the image bitmap.
Now i want to convert this bitmap into valid uri and pass to next activity
if(requestCode==GET_FROM_GALLERY && resultCode == Activity.RESULT_OK) {
Uri selectedImage = data.getData();
System.out.println("URLLL "+selectedImage);
Log.v("PhotoActivity", "Captured image");
//Create intent
Intent intent = new Intent(MainActivity.this, FlagDisplayActivity.class);
intent.putExtra("URI", selectedImage.toString());
//Start Flag Display activity
startActivity(intent);
Log.v("PHOTO ACTIVITY", " uri: " + selectedImage);
}
if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
Intent intent = new Intent(MainActivity.this, FlagDisplayActivity.class);
intent.putExtra("URI", photo);
//Start Flag Display activity
startActivity(intent);
}
This is how i get the uri in next activity
String imageUriString=getIntent().getStringExtra("URI");
final Uri selectedImage=Uri.parse(imageUriString);
and then convert the uri into bitmap like this
Bitmap bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),
selectedImage);
} catch (IOException e) {
e.printStackTrace();
bitmap=StringToBitMap(imageUriString);
}
My main goal is to convert the bitmap into uri
You write your Bitmap into the local Cache of the Application and retrieve it from there.
Bitmap photo = (Bitmap) data.getExtras().get("data");// Get the Bitmap
val file = File(context.cacheDir,"CUSTOM NAME") //Get Access to a local file.
file.delete() // Delete the File, just in Case, that there was still another File
file.createNewFile()
val fileOutputStream = file.outputStream()
val byteArrayOutputStream = ByteArrayOutputStream()
photo.compress(Bitmap.CompressFormat.PNG,100,byteArrayOutputStream)
val bytearray = byteArrayOutputStream.toByteArray()
fileOutputStream.write(bytearray)
fileOutputStream.flush()
fileOutputStream.close()
byteArrayOutputStream.close()
val URI = file.toURI()
Now you can send the URI to another Activity as a String and retrieve the URI from the String and get the Bitmap from the URI.
Intent intent = new Intent(MainActivity.this, FlagDisplayActivity.class);
intent.putExtra("URI", URI.toString());
//Start Flag Display activity
startActivity(intent);
Provide the path of image it will provide you image uri
Uri selectedImageURI = data.getData();
File imageFile = new File(getRealPathFromURI(selectedImageURI));
Uri yourUri = Uri.fromFile(f);
Use the following function so you will get image
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
Try this:
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
imageView.setImageBitmap(bitmap);

I am trying to develop app which save image to gallery.
I want to call the camera through intent, capture images, and save it locally in the gallery
but the issue is image quality is very poor. can anyone help me figure out why?
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
someActivityResultLauncher.launch(cameraIntent);}
#Override
public void onActivityResult(ActivityResult result) {
if (result.getResultCode() == RESULT_OK) {
bitmap = (Bitmap) Objects.requireNonNull(result.getData()).getExtras().get("data");
}
imageView.setImageBitmap(bitmap);
saveimage(bitmap);
}
private void saveimage(Bitmap bitmap){
Uri images;
ContentResolver contentResolver = getContentResolver();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q){
images = MediaStore.Images.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);
}else {
images = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
}
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.Images.Media.DISPLAY_NAME, System.currentTimeMillis() +".jpg");
contentValues.put(MediaStore.Images.Media.MIME_TYPE, "images/*");
Uri uri = contentResolver.insert(images, contentValues);
try {
OutputStream outputStream = contentResolver.openOutputStream(Objects.requireNonNull(uri));
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream);
Objects.requireNonNull(outputStream);
//
}catch (Exception e){
//
e.printStackTrace();
}
}
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
if you get image from data directly, it's in bad quality
Your code is the legacy equivalent of using ActivityResultContracts.TakePicturePreview. It is specifically set up to return a low-resolution bitmap, suitable for a preview.
Instead, use ActivityResultContracts.TakePicture, and supply your destination Uri as part of the contract.
See this and this for more.
I am currently working on an activity that will let the user select an image from the gallery, and then put that image's URI into an SQLite database.
I have another activity where I take that URI and display it on an ImageView. I have this working perfectly on Lollipop and older. But anything newer it crashes when I pull up the activity that displays the image.
Here is the LOGCAT line of the crash:
Caused by: java.lang.SecurityException: Permission Denial: opening provider com.google.android.apps.photos.contentprovider.MediaContentProvider from ProcessRecord{8193e94 13574:jeremy.com.wineofmine/u0a97} (pid=13574, uid=10097) that is not exported from uid 10044
This makes it seem like a permissions thing, but I am requesting the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL STORAGE in the manifest, as well as requesting those permissions on run-time on the activity where it displays the image.
And here is the exact line where it's crashing (this is in the activity where it displays the image:)
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageURI);
And this is imageURI:
imageURI = Uri.parse(cursor.getString(cursor.getColumnIndexOrThrow(WineContract.WineEntry.COLUMN_WINE_IMAGE)));
//This code returns this: content://com.google.android.apps.photos.contentprovider/-1/1/content%3A%2F%2Fmedia%2Fexternal%2Fimages%2Fmedia%2F62/ACTUAL/860591124
Here is the code to the relevant bits.
This is the intent to open up the gallery:
Intent intentGallery = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intentGallery, SELECT_IMAGE);
And this is the onActivityResult method. The main goal of this method is to set the imageThumbail ImageView as the thumbnail, and also to set "photoURI" as the selected image's URI.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
//This is if they choose an image from the gallery
if (requestCode == SELECT_IMAGE && resultCode == RESULT_OK) {
if (requestCode == SELECT_IMAGE) {
// Get the url from data
Uri selectedImageUri = data.getData();
if (null != selectedImageUri) {
// Get the path from the Uri
String path = getPathFromURI(selectedImageUri);
Log.i("ADDACTIVITY", "Image Path : " + path);
bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImageUri);
} catch (IOException e) {
e.printStackTrace();
}
bitmapThumbnail = ThumbnailUtils.extractThumbnail(bitmap,175,175);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmapThumbnail.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byteArray = stream.toByteArray();
// Set the image in ImageView
imageThumbnail.setImageBitmap(bitmapThumbnail);
//Setting photoURI (which gets put into the database) as the gallery's image URI
photoURI = data.getData();
}
}
}
}
Any pointers to what I could be doing wrong, would be great.
Hi when I do something like this
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
In onActivityResult I get thumbnail of the image from the data intent from the camera app
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
And I use that bitmap something like this.
But What if I want the imageuri so that I can get the full size image from it. I tried getting the image uri from the intent something like above
Uri uri = data.getData();
if (uri != null) {
Log.d(TAG, uri.toString());
}else{
Log.d(TAG,"uri is null");
}
Doing like this I get uri is null in my logcat.So can anyone let me know how to get the image uri.I dont want to use EXTRA_OUTPUT and specify my own path.Thanks in advance
There is a well documented bug, which occurs in low resolution devices. Check this thread for the workaround.
There's a bug with that intent in some devices. Take a look at this to know how to workaround it.
In some devices, the Uri is null in onActivityForResult(). So you need
to set Uri to placing the captured image.
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// If there any applications that can handle this intent then call the intent.
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
Uri fileUri = Uri.fromFile(getOutputMediaFile());
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(takePictureIntent, CAMERA_PICKER);
}
public File getOutputMediaFile() {
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir;
// If the external directory is writable then then return the External pictures directory.
if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "MyApp");
} else {
mediaStorageDir = Environment.getDownloadCacheDirectory();
}
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
File mediaFile;
mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg");
return mediaFile;
}
I am developing an application in which i want to capture the image from the camera and display it in another activity in an image view, my problem is that able to capture the image but after capturing i am redirected to first activity instead to second one.
Here is my Code..
PictureOptions.java
public void buttonCameraOpen(View view)
{
// create Intent to take a picture and return control to the calling application
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
// start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
private static Uri getOutputMediaFileUri(int type){
return Uri.fromFile(getOutputMediaFile(type));
}
/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type){
// To be safe, you should check that the SDCard is mounted
// using Environment.getExternalStorageState() before doing this.
File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES), "Easy Heal");
// This location works best if you want the created images to be shared
// between applications and persist after your app has been uninstalled.
// Create the storage directory if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
Log.d("MyCameraApp", "failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile;
if (type == MEDIA_TYPE_IMAGE){
mediaFile = new File(mediaStorageDir.getPath() + File.separator +
"IMG_"+ timeStamp + ".jpg");
} else {
return null;
}
return mediaFile;
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Bitmap selectedphoto = null;
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE && resultCode == RESULT_OK && null!=data) {
// Image captured and saved to fileUri specified in the Intent
//selectedphoto = (Bitmap) data.getExtras().get("data");
Uri selectedImage = data.getData();
String [] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
File f =new File(filePath);
String filename = f.getName();
cursor.close();
selectedphoto = BitmapFactory.decodeFile(filePath);
Intent intent = new Intent(PictureOptions.this,ShowImage.class);
//intent.putExtra("data", selectedphoto);
intent.setData( selectedImage );
startActivity(intent);
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
PictureOptions.xml
<Button

ShowImage.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_image);
ImageView imageview = (ImageView)findViewById(R.id.ImageShow);
Uri imageUri = getIntent().getData();
//Bitmap selectedphoto =(Bitmap)this.getIntent().getParcelableExtra("data");
imageview.setImageURI(imageUri);
}
ShowImage.xml
<ImageView

android:layout_width="fill_parent"
android:layout_height="fill_parent" />
I finally found an awesome solution
This library is used to capture image from camera or select from gallery and return back image in File format in onActivityResult method, which can be used further in the application.
Use
EasyImage Library
Uri uriSavedImage=Uri.fromFile(new File("/sdcard/flashCropped.png"));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);
After clicking the image, check whether it exists or not. Then send the path to the image file to the next activity and display it via Bitmap.
Call the camera intent
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
then on activity for result use this
'case REQUEST_IMAGE_CAPTURE:
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
saveBitmap(imageBitmap);
mimageView1.setImageBitmap(imageBitmap);
mIntent.putExtra("ACTIVITY_CODE", 1);
startActivity(mIntent);
break;
the add this method in ur same class
public void saveBitmap(Bitmap bmp)
{
String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() +"/DCIM";
try
{
File dir = new File(file_path);
if(!dir.exists())
dir.mkdirs();
File file = new File(dir, "time");
cameraUrl=file.getAbsolutePath();
FileOutputStream fOut = new FileOutputStream(file);
bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
}
catch (Exception e) {
Log.e("errr in ","inserting the image at parictular location");
}
}
then call this in ur another activity where u want the image
String valueC = getIntent().getExtras().getString("CAMERA");
Log.v("imageBitmap", ""+valueC);
Bitmap yourSelectedImageC = BitmapFactory.decodeFile(valueC);
mImgV_image.setImageBitmap(yourSelectedImageC);
I have same problem after spending 2 days finally i got the anwer
First activity
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK && data != null) {
Uri uri = data.getData();
Intent intent= new Intent(this,SecondActivity.class);
selfiSrc.putExtra("imgurl", uri );
startActivity(intent);
}
SecondActivity
Imageview iv_photo=(ImageView)findViewById(R.id.iv_photo);
Bundle extras= getIntent().getExtras();
if(extras!=null)
{
path = (Uri) extras.get("imgurl");
iv_photo.setImageURI(path);
}
Another way see my answer
Android - how can i transfer ImageView from one activity to another activity?
I followed the Android developers example of get an image form the camera intent and place it on your view. The problem starts when I try to save that image uri on my SqliteDatabase ( just the link to that image not the full image so I save space) and then I try to restore it on my customadapter.
Link to google dev - > http://developer.android.com/training/camera/index.html
I tried this without success
created a global string logo, and inside handleSmallCameraPhoto put this
private void handleSmallCameraPhoto(Intent intent) {
Bundle extras = intent.getExtras();
mImageBitmap = (Bitmap) extras.get("data");
ImagenViaje.setImageBitmap(mImageBitmap);
ImagenViaje.setVisibility(View.VISIBLE);
--> logo = extras.get("data").toString();
Then I stored logo on SQLite, and tried to restore it on my adapter this way
String imagePath = c.getString(c.getColumnIndexOrThrow(MySQLiteHelper.COLUMN_LOGO_PATH));
Then
ImageView item_image = (ImageView) v.findViewById(R.id.logo);
item_image.setVisibility(ImageView.INVISIBLE);
Bitmap bitmap = BitmapFactory.decodeFile(imagePath);
item_image.setImageBitmap(bitmap);
item_image.setVisibility(ImageView.VISIBLE);
get path of image using
Uri selectedImageUri = intent.getData();
String s1 = intent.getDataString();
String selectedImagePath = getPath(selectedImageUri);
if(selectedImagePath==null && s1 != null)
{
selectedImagePath = s1.replaceAll("file://","");
}
in your handleSmallCameraPhoto method
add this method in your activity
public String getPath(Uri uri) {
try{
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if(cursor==null)
{
return null;
}
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
catch(Exception e)
{
return null;
}
}
save selectedImagePath in your database and use when you need selectedImagePath is path of your selected image
hope help you..
