I am trying to create an onClick event to save an imageview into the phone Gallery by the click of a Button, below is my code. it does not save into the Gallery, can anyone help me figure out why?
sharebtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View b) {
// TODO Auto-generated method stub
//attempt to save the image
b = findViewById(R.id.imageView);
b.setDrawingCacheEnabled(true);
Bitmap bitmap = b.getDrawingCache();
//File file = new File("/DCIM/Camera/image.jpg");
File root = Environment.getExternalStorageDirectory();
File cachePath = new File(root.getAbsolutePath() + "/DCIM/Camera/image.jpg");
try
{
cachePath.createNewFile();
FileOutputStream ostream = new FileOutputStream(cachePath);
bitmap.compress(CompressFormat.JPEG, 100, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}
});
I do this to save Image in gallery.
private void saveImageToGallery(){
imageview.setDrawingCacheEnabled(true);
Bitmap b = imageview.getDrawingCache();
Images.Media.insertImage(getActivity().getContentResolver(), b,title, description);
}
insertImage() will return a String != null if image has been really saved.
Also: Needs permission in the manifest as "android.permission.WRITE_EXTERNAL_STORAGE"
And note that this puts the image at the bottom of the list of images already in the gallery.
Hope this helps.
Suppose the ImageView already keeps the image that you want to save, first, get the Bitmap
imageView.buildDrawingCache();
Bitmap bm=imageView.getDrawingCache();
Then save it with below code:-
MediaStore.Images.Media.insertImage(getContentResolver(), yourBitmap, yourTitle , yourDescription);
And do not forget to set this permission in your manifest:-
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
You have to save the image to media provider. Here is a simple example:
Uri saveMediaEntry(String imagePath,String title,String description,long dateTaken,int orientation,Location loc) {
ContentValues v = new ContentValues();
v.put(Images.Media.TITLE, title);
v.put(Images.Media.DISPLAY_NAME, displayName);
v.put(Images.Media.DESCRIPTION, description);
v.put(Images.Media.DATE_ADDED, dateTaken);
v.put(Images.Media.DATE_TAKEN, dateTaken);
v.put(Images.Media.DATE_MODIFIED, dateTaken) ;
v.put(Images.Media.MIME_TYPE, “image/jpeg”);
v.put(Images.Media.ORIENTATION, orientation);
File f = new File(imagePath) ;
File parent = f.getParentFile() ;
String path = parent.toString().toLowerCase() ;
String name = parent.getName().toLowerCase() ;
v.put(Images.ImageColumns.BUCKET_ID, path.hashCode());
v.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, name);
v.put(Images.Media.SIZE,f.length()) ;
f = null ;
if( targ_loc != null ) {
v.put(Images.Media.LATITUDE, loc.getLatitude());
v.put(Images.Media.LONGITUDE, loc.getLongitude());
}
v.put(“_data”,imagePath) ;
ContentResolver c = getContentResolver() ;
return c.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, v);
}
public static void addImageToGallery(final String filePath, final Context context) {
ContentValues values = new ContentValues();
values.put(Images.Media.DATE_TAKEN, System.currentTimeMillis());
values.put(Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.MediaColumns.DATA, filePath);
context.getContentResolver().insert(Images.Media.EXTERNAL_CONTENT_URI, values);
}
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}

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 use the following code to create image file and save them in to sd card
private File createImageFile(Bitmap bitmap) throws IOException {
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
PICNAME,
".png",
storageDir);
FileOutputStream out = null;
try {
out = new FileOutputStream(image);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (IOException e) {
e.printStackTrace();
}
return image;
}
The issue is that, though I take picture in full screen mode but the above code always saves the image in very less amount of dimension which is 320x240. why so.. is there by any means that I can save the image without resizing?
you can do it like this :
public static Uri takePhotoByCamera(Activity activity) {
File publicDirectory = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES + "/myFolder");
double d = new Random().nextDouble();
File file = new File(publicDirectory, d + ".jpg");
String path = file.getAbsolutePath();
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, path);
values.put(MediaStore.MediaColumns.TITLE, "New Picture");
values.put(MediaStore.Images.ImageColumns.DESCRIPTION, "From your Camera");
activity.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Uri photoUri = Uri.parse("file://" + path);
if (!publicDirectory.exists())
publicDirectory.mkdirs();
else if (!publicDirectory.isDirectory() && publicDirectory.canWrite()) {
publicDirectory.delete();
publicDirectory.mkdirs();
} else {
Log.d("tag550", "can't access");
}
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
activity.startActivityForResult(intent, requestCamera);
return photoUri;
}
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.
MainActivity.java
public void onClick(View v) {
Intent camera = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
//Folder is already created
String dirName = Environment.getExternalStorageDirectory().getPath()
+ "/MyAppFolder/MyApp" + n + ".png";
Uri uriSavedImage = Uri.fromFile(new File(dirName));
camera.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(camera, 1);
n++;
}
AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Go through the following code , its working fine for me.
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("/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 have used mdDroid's code like this:
public void startCamera() {
// Create photo
newPhoto = new Photo();
newPhoto.setName(App.getPhotoName());
//Create folder !exist
String folderPath = Environment.getExternalStorageDirectory() + "/PestControl";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
//create a new file
newFile = new File(folderPath, newPhoto.getName());
if (newFile != null) {
// save image here
Uri relativePath = Uri.fromFile(newFile);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, relativePath);
startActivityForResult(intent, CAMERA_REQUEST);
}
}
Use Like this. It will work for you.
public void onClick(View v) {
Intent camera = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera, 1);
}
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 1:
if(resultCode == RESULT_OK) {
Uri selectedImage = imageReturnedIntent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
//file path of captured image
filePath = cursor.getString(columnIndex);
//file path of captured image
File f = new File(filePath);
filename= f.getName();
Toast.makeText(getApplicationContext(), "Your Path:"+filePath, 2000).show();
Toast.makeText(getApplicationContext(), "Your Filename:"+filename, 2000).show();
cursor.close();
//Convert file path into bitmap image using below line.
// yourSelectedImage = BitmapFactory.decodeFile(filePath);
Toast.makeText(getApplicationContext(), "Your image"+yourSelectedImage, 2000).show();
//put bitmapimage in your imageview
//yourimgView.setImageBitmap(yourSelectedImage);
Savefile(filename,filePath);
}
}
}
public void Savefile(String name, String path) {
File direct = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/");
File file = new File(Environment.getExternalStorageDirectory() + "/MyAppFolder/MyApp/"+n+".png");
if(!direct.exists()) {
direct.mkdir();
}
if (!file.exists()) {
try {
file.createNewFile();
FileChannel src = new FileInputStream(path).getChannel();
FileChannel dst = new FileOutputStream(file).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
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);
}
}
}

I need help with my code that save image to device on android but images are not showing in gallery i tried a lot of different code but not working i need implement it to this code
public class SaveImage extends Activity {
public void saveImage(ImageView imageView) {
Drawable image = imageView.getDrawable();
if(image != null && image instanceof BitmapDrawable) {
BitmapDrawable drawable = (BitmapDrawable) image;
Bitmap bitmap = drawable.getBitmap();
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Picster");
dir.mkdirs();
Date now = new Date();
String timestamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(now);
String path = dir.getPath() + File.separator;
File file = new File(path + "IMG_" + timestamp + ".jpg");
try {
FileOutputStream stream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
stream.flush();
stream.close();
galleryAddPic(file.toString());
} catch (Exception e) {
// TODO: handle exception
}
}
}
public void galleryAddPic(String file) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(file);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
}
i call it in other activity like this
final ImageView image = (ImageView) findViewById(R.id.messageImageView);
Uri imageUri = getIntent().getData();
Picasso.with(this).load(imageUri.toString()).into(image);
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
SaveImage cls2= new SaveImage();
cls2.saveImage(image);
}
});
look on my updated code i add new void galleryAddpic and call it in TRY block it save pictures but still not show in gallery
You just have to add some lines of code to show that image in gallery with instant effect.
Add this code after your file has been created successfully.
Code :
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
Example :
private void galleryAddPic() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
Request the media scanner to scan a file and add it to the media database.
