Now I copy mp4 file from external storage folder and save copy file in gallery with folder. But My gallery app doesn't have folder I code. Surely, File too. But In File Browser, There are exists correctly in DCIM folder.
So, How can I save file in gallery with folder that I code. Please let me know If you can solve this issue.
private void saveToGallery(String recVideoPath) {
progressdialog = new CNetProgressdialog(this);
progressdialog.show();
String folderName = "DuetStar";
String fromPath = recVideoPath;
String toPath = Environment.getExternalStorageDirectory() + "/" + Environment.DIRECTORY_DCIM;
File toPathDir = new File(toPath + "/" + folderName);
final File fromPathFile = new File(fromPath);
File toPathFile = new File(toPath + "/" + folderName, recVideoPath.substring(recVideoPath.lastIndexOf("/") + 1, recVideoPath.length()));
Log.d(TAG, "saveToGallery: " + RecordActivity.currentCreateFileName);
Log.d(TAG, "saveToGallery: " + toPathDir.toString());
Log.d(TAG, "saveToGallery: " + fromPath.toString());
Log.d(TAG, "saveToGallery: " + toPath.toString());
if (!toPathDir.exists()) {
toPathDir.mkdir();
} else {
}
FileInputStream fis = null;
FileOutputStream fos = null;
try {
if (toPathDir.exists()) {
fis = new FileInputStream(fromPathFile);
fos = new FileOutputStream(toPathFile);
byte[] byteArray = new byte[1024];
int readInt = 0;
while ((readInt = fis.read(byteArray)) > 0) {
fos.write(byteArray, 0, readInt);
}
Log.d(TAG, "saveToGallery: " + readInt);
fis.close();
fos.close();
Log.d(TAG, "saveToGallery: " + "Seucceful");
} else {
Toast.makeText(this, "There is no directory", Toast.LENGTH_SHORT).show();
}
} catch (IOException e) {
e.getMessage();
}
progressdialog.dismiss();
}
You can save in specific folder as you wish see this code snippet for idea
String extStorageDirectory;
extStorageDirectory = Environment.getExternalStorageDirectory().toString() + "/Video Folder name/";
//making the folder
new File(extStorageDirectory).mkdirs();
the photo parameter is the bitmap and i checked it and it shows the cuptured image
how can i convert the bitmap to path so i will able to send as an attachment to mail
this is the code :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.opencvhc);
ImgPhoto = (ImageView) findViewById(R.id.ImgPhoto);
Bundle extras = getIntent().getExtras();
if (extras != null) {
bm = (BitmapDataObject) getIntent().getSerializableExtra("photo"); //Obtaining data
bitmap = bm.getBip();
ImgPhoto.setImageBitmap(bitmap);
}
Checkmood = (Button) findViewById(R.id.Checkmood);
Check = (Button) findViewById(R.id.Check);
txtView = (TextView) findViewById(R.id.txt);
}
public void CheckClick(View view) throws IOException {
String file = MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "file", null);
//Uri screenshotUri = Uri.parse(file);
Toast.makeText(OpenCVhc.this, file, Toast.LENGTH_SHORT).show();
final Intent emailIntent1 = new Intent(android.content.Intent.ACTION_SEND);
emailIntent1.putExtra(Intent.EXTRA_EMAIL, new String[]{"comfplatform#gmail.com"});
emailIntent1.putExtra(Intent.EXTRA_SUBJECT, "Image processing picture");
emailIntent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// emailIntent1.putExtra(Intent.EXTRA_STREAM, screenshotUri);
emailIntent1.putExtra(Intent.EXTRA_TEXT, "" +
"We checked your photo with the Ecg-Leads \n 1) : " +
"\n the image proccessing ___ ");
emailIntent1.setType("image/png");
try {
startActivity(Intent.createChooser(emailIntent1, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(OpenCVhc.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
}
See this solution and don't forget to check for "WRITE_EXTERNAL_STORAGE" permission before writing to file.

How to save image in android gallery
(9 answers)
Closed 8 years ago.
I am saving Image from res/drawable to Gallery using InputStream and OutputStream. It works fine and save image. But issue is that It does not update Image in Gallery. If I check folder using ES File Explorer then I can see image there. I also checked ddms, It also update image there as soon as write code executes.It works fine if I save Server Image. How to prevent this issue ? I want to update Gallery as soon as Image save.I also tried MediaScanner to scan folder but no effect.
My Code:
Toast.makeText(context, "Downloading Image...\nPlease Wait.",
Toast.LENGTH_LONG).show();
File direct = new File(Environment.getExternalStorageDirectory()
+ "/Images");
if (!direct.exists()) {
direct.mkdirs();
}
DateFormat dateFormat = new SimpleDateFormat("ddMMyyyy-HHmmss");
Date date = new Date();
String CurrentDateTime = dateFormat.format(date);
InputStream input = null;
OutputStream output = null;
try {
input = context.getResources().openRawResource(
context.getResources().getIdentifier(
"#drawable/" + picName, "drawable",
context.getPackageName()));
output = new FileOutputStream(direct + "/" + "IMG-"
+ CurrentDateTime + ".jpg");
byte[] buf = new byte[1024];
int len;
while ((len = input.read(buf)) > 0) {
output.write(buf, 0, len);
}
MediaScannerConnection.scanFile(context,
new String[] { direct.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
Toast.makeText(context, "Image Saved.", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Log.e("Internal Image Save Error->", e.toString());
Toast.makeText(context,
"Couldn't Save Image.\nError:" + e.toString() + "",
Toast.LENGTH_LONG).show();
} finally {
try {
if (input != null) {
input.close();
}
if (output != null) {
output.close();
}
} catch (IOException ignored) {
Log.e("Internal Image Save Error->", ignored.toString());
Toast.makeText(
context,
"Couldn't Save Image.\nError:" + ignored.toString()
+ "", Toast.LENGTH_LONG).show();
}
}
you must broadcast external directory...
sendBroadcast(new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
if you create external folder in sdcard and then its not display in gallary then use below code.
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
Runtime.getRuntime().exec(
"am broadcast -a android.intent.action.MEDIA_MOUNTED -d file://"
+ CommonVariable.abc_FOLDER);
} else {
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://" + CommonVariable.abc_FOLDER)));
}
other method for scanning.
Uri contentUri = Uri.fromFile(destFile);
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
i hope its useful to you.
Should I be using something other than the MediaScannerConnection.scanFile method to refresh the gallery?
After saving a new jpg I run media scanner to refresh the gallery app like so
MediaScannerConnection.scanFile(this,
new String[] { fullname }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.d("ExternalStorage", "#### Scanned " + path + ":");
Log.d("ExternalStorage", "#### -> uri=" + uri);
}
});
The output of the log shows the following correct output
#### Scanned /data/data/com.mypackage/files/skit_106_01.jpg:
#### -> uri=content://media/external/images/media/95
The gallery app shows no media available
This code has been working perfectly for some time now. It was only when I created an Android avd against version 4.4.2 for further testing that the problem has surfaced.
The code I have seems to be the recommended way of refreshing the gallery app according to Androids documentation so maybe this issue is related to the way I am saving the file, the code for which is as follows.
UPDATE
The code checks for external storage availability and will write to external storage and if external storage is not available it will write the file to internal storage.
private void doSave(String fname, boolean doShare) {
fname = "skit_"+mCurrentSkitId +
"_"+mSkitManager.getCurrentFrameCount(
mCurrentSkitId)+1;
Log.d(TAG, "#### doSave fName = " + fname + " Current skit id = " + mCurrentSkitId);
CharSequence text = getResources().getString(R.string.saved_as)
+ " " + fname;
try {
Bitmap b = mMainView.getSaveBitmap();
if (b == null) {
text = getResources().getString(R.string.save_fail_1);
;
Toast.makeText(this, text, Toast.LENGTH_LONG).show();
return;
}
fname = FileUtils.replaceInvalidFileNameChars(fname);
String value = fname;
File folder = FileUtils.getWritableFolder(this);
/*
* String folder =
* Environment.getExternalStorageDirectory().toString() +
* "/Pictures"; try { folder =
* Environment.getExternalStoragePublicDirectory
* (Environment.DIRECTORY_PICTURES).toString(); } catch
* (NoSuchFieldError e) {
*
* }
*/
String ext = ".jpg";
if (mPrefs.getString("format", "JPG").equals("PNG"))
ext = ".png";
String fullname = folder.getAbsolutePath() + File.separator + value
+ ext;
Map<String, String> hm = new HashMap<String, String>();
hm.put("filename", fullname);
FileOutputStream fos;
if (folder == getFilesDir())
fos = openFileOutput(value + ext, Context.MODE_WORLD_WRITEABLE);
else {
File f2 = new File(fullname);
fos = new FileOutputStream(f2);
}
b.compress(CompressFormat.JPEG, 95, fos);
fos.close();
String[] str = new String[1];
str[0] = fullname;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.FROYO) {
MediaScannerConnection.scanFile(this,
new String[] { fullname }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.d("ExternalStorage", "#### Scanned " + path + ":");
Log.d("ExternalStorage", "#### -> uri=" + uri);
}
});
}
text = text + value + ext + " "
+ getResources().getString(R.string.saved_end);
;
mLastSaveName = value;
setDetailTitle();
mSkitManager.createFrame(mCurrentSkitId, fullname);
} catch (Exception e) {
Map<String, String> hm = new HashMap<String, String>();
hm.put("text", e.toString());
e.printStackTrace();
text = getResources().getString(R.string.save_fail_2)
+ e.toString();
} catch (Error e) {
Map<String, String> hm = new HashMap<String, String>();
hm.put("text", e.toString());
e.printStackTrace();
text = getResources().getString(R.string.save_fail_2)
+ e.toString();
}
Toast.makeText(this, text, Toast.LENGTH_SHORT).show();
}
The code that does the check for external storage availability looks like this
public static File getWritableFolder(Context context) {
File folder = context.getFilesDir();
if (externalStorageAvailable()) {
try {
folder = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
if (!folder.exists() || !folder.canWrite()) {
folder = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
}
if (!folder.exists() || !folder.canWrite()) {
folder = Environment.getExternalStorageDirectory();
}
} catch (Exception e) {
folder = Environment.getExternalStorageDirectory();
} catch (Error e) {
folder = Environment.getExternalStorageDirectory();
}
if (!folder.exists() || !folder.canWrite()) {
folder = context.getFilesDir();
}
}
return folder;
}
private static boolean externalStorageAvailable() {
boolean mExternalStorageAvailable;
boolean mExternalStorageWriteable;
String state = Environment.getExternalStorageState();
if (state.equals(Environment.MEDIA_MOUNTED)) {
// We can read and write the media
mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (state.equals(Environment.MEDIA_MOUNTED_READ_ONLY)) {
// We can only read the media
mExternalStorageAvailable = true;
mExternalStorageWriteable = false;
} else {
// Something else is wrong. It may be one of many other states, but
// all we need
// to know is we can neither read nor write
mExternalStorageAvailable = mExternalStorageWriteable = false;
}
return mExternalStorageAvailable && mExternalStorageWriteable;
}
If anyone is able to pick holes in any of the above that might help to solve this issue then that would be great.
i was having mixed results with MediaScannerConnection so i used the sendBroadcast method instead. I do not know if the sendBroadcast method is not standard/should not be used but it works for me.
public void galleryAddPic(File currentPhotoPath) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(currentPhotoPath);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
Also regarding the MediaScannerConnection : https://stackoverflow.com/a/4825615/1497188
I have a little issue with creating a directory and saving a file to it on my android application. I'm using this piece of code to do this :
String filename = "MyApp/MediaTag/MediaTag-"+objectId+".png";
File file = new File(Environment.getExternalStorageDirectory(), filename);
FileOutputStream fos;
fos = new FileOutputStream(file);
fos.write(mediaTagBuffer);
fos.flush();
fos.close();
But it's throwing an exception :
java.io.FileNotFoundException: /mnt/sdcard/MyApp/MediaCard/MediaCard-0.png (No such file or directory)
on that line : fos = new FileOutputStream(file);
If I set the filename to : "MyApp/MediaTag-"+objectId+" it's working, but If I try to create and save the file to an another directory it's throwing the exception. So any ideas what I'm doing wrong?
And another question: Is there any way to make my files private in external storage so user can't see them in gallery, only if he connect his device as Disk Drive?
Use this function to save your bitmap in SD card
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
if (!myDir.exists()) {
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())));
look at this link also http://rajareddypolam.wordpress.com/?p=3&preview=true
The code presented by RajaReddy no longer works for KitKat
This one does (2 changes):
private void saveImageToExternalStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).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();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, 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);
}
});
}
Update 2018, SDK >= 23.
Now you should also check if the user has granted permission to external storage by using:
public boolean isStoragePermissionGranted() {
String TAG = "Storage Permission";
if (Build.VERSION.SDK_INT >= 23) {
if (this.checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
Log.v(TAG, "Permission is granted");
return true;
} else {
Log.v(TAG, "Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG,"Permission is granted");
return true;
}
}
public void saveImageBitmap(Bitmap image_bitmap, String image_name) {
String root = Environment.getExternalStorageDirectory().toString();
if (isStoragePermissionGranted()) { // check or ask permission
File myDir = new File(root, "/saved_images");
if (!myDir.exists()) {
myDir.mkdirs();
}
String fname = "Image-" + image_name + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) {
file.delete();
}
try {
file.createNewFile(); // if file already exists will do nothing
FileOutputStream out = new FileOutputStream(file);
image_bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(this, new String[]{file.toString()}, new String[]{file.getName()}, null);
}
}
and of course, add in the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
You need a permission for this
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and method:
public boolean saveImageOnExternalData(String filePath, byte[] fileData) {
boolean isFileSaved = false;
try {
File f = new File(filePath);
if (f.exists())
f.delete();
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
fos.write(fileData);
fos.flush();
fos.close();
isFileSaved = true;
// File Saved
} catch (FileNotFoundException e) {
System.out.println("FileNotFoundException");
e.printStackTrace();
} catch (IOException e) {
System.out.println("IOException");
e.printStackTrace();
}
return isFileSaved;
// File Not Saved
}
Make sure your app has the proper permissions to be allowed to write to external storage: http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE

Probably exception is thrown because there is no MediaCard subdir. You should check if all dirs in the path exist.
About visibility of your files: if you put file named .nomedia in your dir you are telling Android that you don't want it to scan it for media files and they will not appear in the gallery.
For API level 23 (Marshmallow) and later, additional to uses-permission in manifest, pop up permission should also be implemented, and user needs to grant it while using the app in run-time.
Below, there is an example to save hello world! as content of myFile.txt file in Test directory inside picture directory.
In the manifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Where you want to create the file:
int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
String[] PERMISSIONS_STORAGE = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (permission != PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(MainActivity.this,PERMISSIONS_STORAGE, 1);
}
File myDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Test");
myDir.mkdirs();
try
{
String FILENAME = "myFile.txt";
File file = new File (myDir, FILENAME);
String string = "hello world!";
FileOutputStream fos = new FileOutputStream(file);
fos.write(string.getBytes());
fos.close();
}
catch (IOException e) {
e.printStackTrace();
}
Old way of saving files might not work with new versions of android, starting with android10.
fun saveMediaToStorage(bitmap: Bitmap) {
//Generating a dummy file name
val filename = "${System.currentTimeMillis()}.jpg"
//Output stream
var fos: OutputStream? = null
//For devices running android >= Q
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {

Reference- https://www.simplifiedcoding.net/android-save-bitmap-to-gallery/
since android 4.4 file saving has been changed. there is
ContextCompat.getExternalFilesDirs(context, name);
it retuns an array.
when name is null
the first value is like /storage/emulated/0/Android/com.my.package/files
the second value is like
/storage/extSdCard/Android/com.my.package/files
android 4.3 and less it retuns a single item array
parts of little messy code but it demonstrates how it works:
/** Create a File for saving an image or video
* #throws Exception */
private File getOutputMediaFile(int type) throws Exception{
// Check that the SDCard is mounted
File mediaStorageDir;
if(internalstorage.isChecked())
{
mediaStorageDir = new File(getFilesDir().getAbsolutePath() );
}
else
{
File[] dirs=ContextCompat.getExternalFilesDirs(this, null);
mediaStorageDir = new File(dirs[dirs.length>1?1:0].getAbsolutePath() );
}
// Create the storage directory(MyCameraVideo) if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
output.setText("Failed to create directory.");
Toast.makeText(this, "Failed to create directory.", Toast.LENGTH_LONG).show();
Log.d("myapp", "Failed to create directory");
return null;
}
}
// Create a media file name
// For unique file name appending current timeStamp with file name
java.util.Date date= new java.util.Date();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",Locale.ENGLISH) .format(date.getTime());
File mediaFile;
if(type == MEDIA_TYPE_VIDEO) {
// For unique video file name appending current timeStamp with file name
mediaFile = new File(mediaStorageDir.getPath() + File.separator + slpid + "_" + pwsid + "_" + timeStamp + ".mp4");
}
else if(type == MEDIA_TYPE_AUDIO) {
// For unique video file name appending current timeStamp with file name
mediaFile = new File(mediaStorageDir.getPath() + File.separator + slpid + "_" + pwsid + "_" + timeStamp + ".3gp");
} else {
return null;
}
return mediaFile;
}
/** Create a file Uri for saving an image or video
* #throws Exception */
private Uri getOutputMediaFileUri(int type) throws Exception{
return Uri.fromFile(getOutputMediaFile(type));
}
//usage:
try {
file=getOutputMediaFileUri(MEDIA_TYPE_AUDIO).getPath();
} catch (Exception e1) {
e1.printStackTrace();
return;
}
This code is Working great & Worked on KitKat as well. Appreciate #RajaReddy PolamReddy
Added few more steps here and also Visible on Gallery as well.
public void SaveOnClick(View v){
File mainfile;
String fpath;
try {
//i.e v2:My view to save on own folder
v2.setDrawingCacheEnabled(true);
//Your final bitmap according to my code.
bitmap_tmp = v2.getDrawingCache();
File(getExternalFilesDir(Environment.DIRECTORY_PICTURES)+File.separator+"/MyFolder");
Random random=new Random();
int ii=100000;
ii=random.nextInt(ii);
String fname="MyPic_"+ ii + ".jpg";
File direct = new File(Environment.getExternalStorageDirectory() + "/MyFolder");
if (!direct.exists()) {
File wallpaperDirectory = new File("/sdcard/MyFolder/");
wallpaperDirectory.mkdirs();
}
mainfile = new File(new File("/sdcard/MyFolder/"), fname);
if (mainfile.exists()) {
mainfile.delete();
}
FileOutputStream fileOutputStream;
fileOutputStream = new FileOutputStream(mainfile);
bitmap_tmp.compress(CompressFormat.JPEG, 100, fileOutputStream);
Toast.makeText(MyActivity.this.getApplicationContext(), "Saved in Gallery..", Toast.LENGTH_LONG).show();
fileOutputStream.flush();
fileOutputStream.close();
fpath=mainfile.toString();
galleryAddPic(fpath);
} catch(FileNotFoundException e){
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
This is Media scanner to Visible in Gallery.
private void galleryAddPic(String fpath) {
Intent mediaScanIntent = new Intent("android.intent.action.MEDIA_SCANNER_SCAN_FILE");
File f = new File(fpath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
}
