Question

 if (action.equals("saveToGallery")) {

                        JSONObject obj = args.getJSONObject(0);
                        String imageSource = obj.has("imageSrc") ? obj.getString("imageSrc") : null;
                        String imageName = obj.has("imageName") ? obj.getString("imageName") : null;
                        String savedImgSrc = saveImageToGallery(imageSource, imageName);
                        Log.v("SAve To Gallery ", "saved file url:  " + savedImgSrc);

                        return new PluginResult(PluginResult.Status.OK);
                    }
                    return new PluginResult(PluginResult.Status.INVALID_ACTION);
                } catch (JSONException e) {
                    e.printStackTrace();
                    return new PluginResult(PluginResult.Status.JSON_EXCEPTION);
                }

public String saveImageToGallery(String imgSrc, String imgName) {
        Log.v("Save To Gallery ", "image SRc:  " + imgSrc + " , image Name:"
                + imgName);

        Context ctx = this.ctx;
        AssetManager assmgr = ctx.getAssets();
        File tempDir = new File("/sdcard/HarmonyDayApp/wallpapers/");
        tempDir.mkdirs();
        File file = new File(tempDir, imgName);
        try {
            InputStream is = null;
            is = assmgr.open("www/" + imgSrc);
            OutputStream os = new FileOutputStream(file);
            byte[] data = new byte[is.available()];
            is.read(data);
            os.write(data);
            sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
            is.close();
            os.close();
        } catch (IOException ex) {
            Log.w("ExternalStorage", "Error writing " + file, ex);
        }
        return file.getAbsolutePath();

    }

This is the code I am using to save the image to the device gallery. However, after the image is saved, if i check the gallery imeediately, the image is not there. It comes when i reload the application, or the gallery after sometime. Any suggestion to this problem will be helpful.

Answer 1

Try this:

After adding your image in gallery you need to broadcast

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(“file://”+
 Environment.getExternalStorageDirectory())));

Hopefully it will work for you. 🙂
