I can't save my bitmap to the Gallery in Andro

Question

I'm trying to save my edited image into Gallery from where user can access it. I have used "Add the photo to the Gallery" from reference: https://developer.android.com/training/camera/photobasics.html

Here is my Code:

String mCurrentPhotoPath;
public void startSave() {

    FileOutputStream fileOutputStream = null;
    File new_file = null;

    try {
        new_file = createImageFile();
        fileOutputStream = new FileOutputStream(new_file);
        imageView.setDrawingCacheEnabled(true);
        Bitmap bitmap = Bitmap.createBitmap(imageView.getDrawingCache());
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream);
        Toast.makeText(this, "save Image Success", Toast.LENGTH_SHORT).show();
        fileOutputStream.flush();
        fileOutputStream.close();
    }
    catch (FileNotFoundException e){
        e.printStackTrace();
    }
    catch (IOException e){
        e.printStackTrace();
    }

    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);
}

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */
            ".jpg",         /* suffix */
            storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}

I have also changed AndroidManifest.xml like this and given permission to write in external storage and granted Uri permission.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mypackage">
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.mypackage.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
    </provider>
</application>

I have added xml file paths according to this:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" 
path="Android/data/com.sparkexel.blurd1/files/Pictures" />
</paths>

I can't get my head around what is the problem here. First, there was an error message about external permission or URI permission not granted. I have set URI permission after that. Finally, There is no error message in console. But I can't save my image into the gallery. I have logged path of my saved file. and it is:

/storage/emulated/0/Android/data/com.mypackage/files/Pictures/JPEG_20171216_171109_2682421804312420480.jpg

From that, I assumed that file is saving successfully. But it does not show up in Gallery. I have tried many solutions but nothing works. Please help me.

Answer 1

The File Will be Displayed only if after a Successful Completion of media Scanner.

Note

1. Save the File To the External Storage . Now the Path is Android Data Folder. Most of the time the Files inside the data Folder wont be Scanned By Media Scanner. For that use Environment.getExternalStorageDirectory().getAbsolutePath()+"/Pictures/Foldername/" as Folder Path

   Environment.getExternalStorageDirectory().getAbsolutePath() will Return the ExternalStorge as the Path

2. Run Media Scanner
