Questions reagarding bitmap image and image storage - android

I have the bitmap image that I got from my camera activity. Can someone please guide me as to how can I store this image in the gallery?
code:
In my button OnClickListener
Intent campic=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(campic,cameradata );
In my onActivityResult
if(resultCode==RESULT_OK)
{
Bundle bun=data.getExtras();
bmp=(Bitmap)bun.get("data");
SaveIamge(bmp);
iveventpic.setImageBitmap(bmp);
}

call this function to save bitmap in sdcard:
private void SaveIamge(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
By calling this line u have to store that image in the gallery:
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
and Add permission in the manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

MediaStore.Images.Media.insertImage(getContentResolver(), bmp, title, desc);
As seen in this post.

Please try this:-

String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
String fname = "filename.jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {

}
You have to give runtime permissions for nougat for saving your file.

How to save image in external storage from bitmap in android

I am using ACTION_IMAGE_CAPTURE to capture image using camera. It works fine, But the problem is that image is showing in imageview after clicking but can not saved in external or internal storage. Here is my code for saving image in external storage.
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile() + "/DashBoard/");
file.mkdirs();
ticket = Environment.getExternalStorageDirectory().getAbsolutePath() + "/DashBoard/Ticket.jpg";
file4 = new File(file, ticket);
try {
FileOutputStream out = new FileOutputStream(file4);
bitmap.compress(Bitmap.CompressFormat.JPEG , 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
ivTicket.setImageBitmap(bitmap);
Any solution ?
Use ImageWorker Library for easily saving bitmaps/drawables/base64.
How to Save
ImageWorker.to(context).
directory("ImageWorker").
subDirectory("SubDirectory").
setFileName("Image").
withExtension(Extension.PNG).
save(sourceBitmap,85)
Easy as that. Contributions are welcomed.
Follow it -
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ())
file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
and add this in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
EDIT: By using this line you will be able to see saved images in the gallery view.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
Reference
Try This:
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
and add this in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

UPDATE
instead of Environment.getExternalStorageDirectory() you can use your storage location as API level 30 and above Storage-policy is changed.

Image Saved In Phone Storage Instead of SD Card and Also not Showing in Phone Gallery Why?

I am having an application containing different images using ImageView and ViewPager. I want to save the current image shown through ImageView in SD Storage. But it always saved in Phone Storage successfully.
I want to save the image in SD Card and also saved image not showing in Gallery Why? Kindly help me out in this issue:
public void SaveIamge() {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/Cute_Baby_Images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
int currentImagePos = viewPager.getCurrentItem();
Drawable drawable = viewPager.getResources().getDrawable(images[currentImagePos]);
Bitmap finalBitmap = ((BitmapDrawable) drawable).getBitmap();
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Toast.makeText(this, "Sucessfully Save Image", Toast.LENGTH_LONG).show();
}
Environment.getExternalDirectory() returns phone storage. To get location of SD card, check Find an external SD card location
To make the images appear in gallery, you should let the media scanner scan the file using MediaScannerConnection.scanFile()
Check Image, saved to sdcard, doesn't appear in Android's Gallery app
Create a function called getDirectory()
private static File getDirectory(String variableName, String... paths) {
String path = System.getenv(variableName);
if (!TextUtils.isEmpty(path)) {
if (path.contains(":")) {
for (String _path : path.split(":")) {
File file = new File(_path);
if (file.exists()) {
return file;
}
}
} else {
File file = new File(path);
if (file.exists()) {
return file;
}
}
}
if (paths != null && paths.length > 0) {
for (String _path : paths) {
File file = new File(_path);
if (file.exists()) {
return file;
}
}
}
//If any there is no SECONDARY STORAGE are detected return INTERENAL STORAGE
return Environment.getExternalStorageDirectory();
}
Change your code to
public void SaveIamge() {
String root = getDirectory("SECONDARY_STORAGE").getAbsolutePath();
File myDir = new File(root + "/Cute_Baby_Images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
int currentImagePos = viewPager.getCurrentItem();
Drawable drawable = viewPager.getResources().getDrawable(images[currentImagePos]);
Bitmap finalBitmap = ((BitmapDrawable) drawable).getBitmap();
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Toast.makeText(this, "Sucessfully Save Image", Toast.LENGTH_LONG).show();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + root)));
}
I have added a broadcast to notify the MediaScanner to re-scan the filesystem for new files. This will fix the problem of images are not showing in the gallery.

how to save an image file in android?

I want save an image file in android, and the system gallery can view it or delete it. I use the following code, but found gallery could not find it,let alone view it or delete it. Any suggestion?
private void saveImage(Bitmap finalBitmap){
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + getString(R.string.folderName));
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".png";
File file = new File (myDir, fname);
if (file.exists ()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
} catch (Exception e) {
e.printStackTrace();
}
}
Just change this line :
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
To:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
if you want gallery to scan and add your app image folder then try this code after you save the image.
MediaScannerConnection.scanFile(this,new String[] { imagePath }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
if(Config.LOG_DEBUG_ENABLED) {
// if required do something after the scan complet
Log.d(TAG, "scanned : " + path);
}
}

Unable to save Bitmap Image

Hi I Am Trying to save my new bitmap image after applying filter into the SD-card or gallery. I am using this Code to save my bitmap that I have found on Stack overflow as well, but this code is not working for me
public void saveImage(View view) {
/*MediaStore.Images.Media.insertImage(getContentResolver(),newBitmap,"Image-Name","description");*/
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
newBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Toast.makeText(this,"Image Saved In SD Card",Toast.LENGTH_LONG).show();
}
Please let me know If I am doing any thing wrong?
Thanks in advance.
Make sure that you have added permission to write to sdcard
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
