Passing Image from ios/c++ code to JNI Android

I want to provide a feature for the user to save a screenshot of the current screen. I am using cocos2d-x v3.0 and c++, and am implementing this feature for the first time. I did some googling and found this piece of code

This Code Work Perfectly for store image in ios photos

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
                                                     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* path = [documentsDirectory stringByAppendingPathComponent: 
                  [NSString stringWithUTF8String: filename] ];
UIImage* image = [UIImage imageWithContentsOfFile:path];

UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

I think byte array may resolve my problem but i don't know how to transfer this image to android via jni method/byte array

Some more code snippet

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

std::string str =  CCFileUtils::sharedFileUtils()->getWritablePath();
str.append("/imageNameToSave.png");
const char * c = str.c_str();
tex->saveToFile(c);

this->scheduleOnce(schedule_selector(Dressup_screen_BG_button_view::Photo_Save_Gallery_Android),1.0);

#else

tex->saveToFile("imageNameToSave.png", kCCImageFormatPNG);
 this->scheduleOnce(schedule_selector(Dressup_screen_BG_button_view::Photo_Save_Gallery),1.0);
#endif


// This is native method which will save photo 
-( void )ThisPhotoClick{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *yourArtPath = [documentsDirectory stringByAppendingPathComponent:@"/imageNameToSave.png"];

UIImage *image = [UIImage imageWithContentsOfFile:yourArtPath];

UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert !" message:@"Photo Saved To Photos." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];}

Android Method

public  static void SaveImageAndroidJNI(final boolean visible)
{

    ContextWrapper c = new ContextWrapper(me);
    String path = c.getFilesDir().getPath() + "/imageNameToSave.png";
    System.out.println("Paht to check --"+path);
    File imgFile = new File(path);

    Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
    ArrayList<Uri> uris = new ArrayList<Uri>();
    uris.add(Uri.parse(path));

    OutputStream output;
    // Find the SD Card path



    File filepath = Environment.getExternalStorageDirectory();

    // Create a new folder in SD Card
    File dir = new File(filepath.getAbsolutePath()
            + "/Your Folder Name/");
    dir.mkdirs();

    // Create a name for the saved image
    File file = new File(dir, "imageNameToSave.png");

    try {

        output = new FileOutputStream(file);

        // Compress into png format image from 0% - 100%
        myBitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
        output.flush();
        output.close();
    }

    catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    Intent intent = new Intent();
    Uri pngUri = Uri.fromFile(file);


    intent.setAction(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_STREAM, pngUri);
    intent.setType("image/jpeg");

    me.startActivity(Intent.createChooser(intent, "Share Image"));
}

Note

getWritablePath(); Now not working due to runtime permission issue, I already try to ask for permission at start of android app but still not working so don't suggest me to do this

I Want to save captured image in my android device but i can't find way

My implementation is reference from this question but it's not working

Any help much appreciable
