My app uses the phone camera to take pictures and save them in a specific folder. I can't see them with Android Gallery or plugging into my pc, but I can using a file manager app.
I found a solution to this: I rename pictures with a file manager app and the I can see them in the gallery.
The code I'm using is:
Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String dirName = Environment.getExternalStorageDirectory()+"/MyAPP/APP"+ n +".jpg";
Uri uriSavedImage = Uri.fromFile(new File(dirName));
camera.putExtra(MediaStore.EXTRA_OUTPUT,uriSavedImage);
startActivityForResult(camera, 1);
n++;
AndroidManifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
for save image to specific folder,
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/DirName");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/DirName/");
wallpaperDirectory.mkdirs();
}
File file = new File(new File("/sdcard/DirName/"), fileName);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
try this for accessing that image
private void showImage(String imageName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/SlamImages");
if (direct.exists()) {
File f = new File(Environment.getExternalStorageDirectory() + "/SlamImages/" + imageName);
if (f.exists() && !imageName.equals("")) {
Bitmap bmp = BitmapFactory.decodeFile(f.getAbsolutePath());
imgUserLogo.setImageBitmap(bmp);
} else {
imgUserLogo.setImageResource(R.drawable.friend_image);
Toast.makeText(FriendsDetailsActivity.this, "Image Does not exist", Toast.LENGTH_SHORT).show();
}
}
}
I just needed to add some code to scan the picture and add it to the gallery
private void addGallery() {
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
String currentPath = Environment.getExternalStorageDirectory()
+ "/MyAPP/APP" + n + ".jpg";
File f = new File(currentPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
I added it in onActivityResult and it works

I am trying to convert entire CardView into an Image and then I want to share it using different apps.
PROBLEM
cardView.setDrawingCacheEnabled(true);
cardView.measure(View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED));
cardView.layout(0,0, cardView.getMeasuredWidth(), cardView.getMeasuredHeight());
cardView.buildDrawingCache(true);
bitmap = Bitmap.createBitmap(cardView.getDrawingCache());
cardView.setDrawingCacheEnabled(false);
String path = MediaStore.Images.Media.insertImage(DetailedActivity.this.getContentResolver(),bitmap,"quote",null);
uri = Uri.parse(path);
Thing is I am getting cardview converted into bitmap but while getting uri from bitmap it is returning null path. so while converting Uri it is giving NULL POINTER EXCEPTION.
Below is the list of permissions I provided.
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL"
tools:ignore="ProtectedPermissions" />
CardView XML
If I give the CardView a defined hardcoded values for Height and Width of a CardView it is working but when I use
android:layout_width="match_parent"
android:layout_height="match_parent"
With the code shown above it is giving NULL_POINTER_EXCEPTION.
QUERIES
1. How can I make it work?
2. Is there any other way to do this?
So if I get it right, the URI path is stored in uri variable. The null error happens because you didn't initialise that uri string. You can do this:
String uri = new String() // -> if there is still an error here, replace String() with String(this) or String(activity_your_name.this)
Intent intent = new Intent(this, activity_output.class); // -> here you add the activity where you send the URI to
intent.putExtra("URI", uri);
and on the other activities you extract the URI through:
//Getting the URI from previous activity:
path = getIntent().getExtra("URI");
//Initialising the File form your URI
File StringToBitmap = new File;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
StringToBitmap = new File(path, String.valueOf(options));
//Your bitmap will be stored in mBitmaps
mBitmaps = BitmapFactory.decodeFile(path);
//The next part is extra, if you want to display your bitmap into an ImageView
ImageView iv = new ImageView();
iv = findViewById(R.id.your_id);
iv.setImageBitmap(mBitmaps);
This code worked to me for something very similar. And about that NULL EXCEPTION, every time you get it, try to see if you initialised all your objects correctly. Hope this helps.
Try This:
public Bitmap getScreenShot(View view) {
view.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
view.setDrawingCacheEnabled(false);
return bitmap;
}
public void onShareImage(Bitmap bitmap) {
#SuppressLint("SimpleDateFormat") String fileName = "IMG_" + new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()) + ".PNG";
storeScreenShot(bitmap, fileName);
Uri imgUri = Uri.fromFile(new File(VarName.SCREENSHOT_DIRECTORY + "/" + fileName));
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, imgUri);
shareIntent.putExtra(Intent.EXTRA_TEXT, VarName.DRESS_ME_SHARE_MASSAGE_HEADER + "\n" + VarName.DRESS_ME_SHARE_APP_LINK);
startActivity(Intent.createChooser(shareIntent, "Share Image"));
}
public void storeScreenShot(Bitmap bm, String fileName) {
File dir = new File(VarName.SCREENSHOT_DIRECTORY);
if (!dir.exists()) {
dir.mkdirs();
File file = new File(dir.getAbsolutePath(), ".nomedia");
try {
file.createNewFile();
final Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
final Uri contentUri = Uri.fromFile(file);
scanIntent.setData(contentUri);
sendBroadcast(scanIntent);
} catch (IOException e) {
e.printStackTrace();
}
}
File file = new File(VarName.SCREENSHOT_DIRECTORY, fileName);
try {
FileOutputStream fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
file.createNewFile();
final Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
final Uri contentUri = Uri.fromFile(file);
scanIntent.setData(contentUri);
sendBroadcast(scanIntent);
} catch (Exception e) {
e.printStackTrace();
}
}
Now you Just need to call function.
Bitmap bitmap = getScreenShot(cardView);
onShareImage(bitmap);
I need to save the pictures taken with my app in an specific folder. I've read many solutions to this problem but I couldn't make any of them work so I ask for help.

Uri relativePath = Uri.fromFile(newFile);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, relativePath);

}
Use Like this. It will work for you.

Hope this will help you. for reference to use camera intent.
Here You Go. I tried the above solution they save the image to gallery but the image is not visible , a 404 error is visible on the image , and i figured it out .

I have found an easier code to do it.
This is the code for creating the image folder:
private File createImageFile(){
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/App Folder/";
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "AppName_" + timeStamp;
String file = dir +imageFileName+ ".jpg" ;
File imageFile = new File(file);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = imageFile.getAbsolutePath();
return imageFile;
}
,And this is the code for launching the camera app and take the photo:
public void lunchCamera() {
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 = createImageFile();
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.ziad.sayit",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}

When using Android KitKat and above, it is impossible for an app to save a file onto the SDCard.
Check this Thread
UPDATE
Save an image to internal storage:
public static Uri saveImage(Bitmap bmp) {
Uri uri = null;
try {
String name = System.currentTimeMillis() + ".jpg";
//you can create a new file name "test.jpg" in sdcard folder.
File f = new File(getImagesDir() + File.separator + name);
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bitmapToByteArray(bmp));
// remember close de FileOutput
fo.close();
uri = Uri.parse("file://" + f.getPath());
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return uri;
}
public static String getImagesDir() {
String rootDir = Environment.getExternalStorageDirectory().toString();
rootDir = rootDir + "/MyApp/Media/Images";
// Create directory if not existed
File dir = new File(rootDir);
if (!dir.exists()) {
dir.mkdir();
}
return dir.getPath();
}
public static byte[] bitmapToByteArray(Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
return byteArray;
}
UPDATE 2: missing code added
Add the following permissions to your AndroidManifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
I have an app where the user creates an image and then I want to save it so it's visible form the default gallery application.
Now I don't want the pictures to be saved in the same folder as the pictures taken from the camera, I want them to be saved in a folder dedicated to the app, just like images from apps like whatsapp or facebook.
I've tried saving them in this two locations:
File imagePath = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)+ File.separator + appDirectoryName + File.separator);
and here
File imagePath = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+ File.separator + appDirectoryName + File.separator);
If I browse through the phone I see that I successfully save the images but they don't show in the gallery app. It is obvious that I'm missing something but I don't know what it is. Maybe adding some kind of metadata to the files or folders so the gallery recognizes them?
Well I found the answer in the end.
It turned out to be what I suspected. The saved image needs to have some metadata added in order to be seen in the gallery (at least in my device).
This is what I did:
OutputStream fOut = null;
File file = new File(imagePath,"GE_"+ System.currentTimeMillis() +".jpg");
try {
fOut = new FileOutputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
try {
fOut.flush();
fOut.close();
} catch (IOException e) {
e.printStackTrace();
}
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, this.getString(R.string.picture_title));
values.put(Images.Media.DESCRIPTION, this.getString(R.string.picture_description));
values.put(Images.Media.DATE_TAKEN, System.currentTimeMillis ());
values.put(Images.ImageColumns.BUCKET_ID, file.toString().toLowerCase(Locale.US).hashCode());
values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, file.getName().toLowerCase(Locale.US));
values.put("_data", file.getAbsolutePath());
ContentResolver cr = getContentResolver();
cr.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
I have had the same problem.
The second way is the correct way, but you don't see the images in the Gallery because the gallery needs to be refreshed.
So, you can wait a while until it refreshes itself, or you can use the MediaScanner -
look here
Hope this helped!
I did the following to get it to work:
public void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_MOUNTED);
String mCurrentPhotoPath = "file:" + image.getAbsolutePath(); // image is the created file image
File file = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
}
Try this
private void createDirectoryAndSaveFile(Bitmap imageToSave, String fileName) {
File direct = new File(Environment.getExternalStorageDirectory() + "/DirName");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/DirName/");
wallpaperDirectory.mkdirs();
}
File file = new File(new File("/sdcard/DirName/"), fileName);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
I tried this it works perfectly.
private Uri imageUri;
String getimgname, getimgpath;
intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File photo = new File(Environment.getExternalStorageDirectory(), "IMG"+System.currentTimeMillis()+".jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
getimgname = photo.getName();
getimgpath = photo.getAbsolutePath();
Try this
MediaScannerConnection.scanFile(context,
new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}

I have found an easier code to do it.
This is the code for creating the image folder:
private File createImageFile(){
final String dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/App Folder/";
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "AppName_" + timeStamp;
String file = dir +imageFileName+ ".jpg" ;
File imageFile = new File(file);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = imageFile.getAbsolutePath();
return imageFile;
}
,And this is the code for launching the camera app and take the photo:
public void lunchCamera() {
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 = createImageFile();
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.ziad.sayit",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
