How to save Image in shared preference in Android | Shared preference issue in Android with Image

I solved your problem do something like that:

1. Write Method to encode your bitmap into string base64-

   // method for bitmap to base64
   public static String encodeTobase64(Bitmap image) {
       Bitmap immage = image;
       ByteArrayOutputStream baos = new ByteArrayOutputStream();
       immage.compress(Bitmap.CompressFormat.PNG, 100, baos);
       byte[] b = baos.toByteArray();
       String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT);
   
       Log.d("Image Log:", imageEncoded);
       return imageEncoded;
   }
   

2. Pass your bitmap inside this method like something in your preference:

   SharedPreferences.Editor editor = myPrefrence.edit();
   editor.putString("namePreferance", itemNAme);
   editor.putString("imagePreferance", encodeTobase64(yourbitmap));
   editor.commit();
   

3. And when you want to display your image just anywhere, convert it into a bitmap again using the decode method:

   // method for base64 to bitmap
   public static Bitmap decodeBase64(String input) {
       byte[] decodedByte = Base64.decode(input, 0);
       return BitmapFactory
               .decodeByteArray(decodedByte, 0, decodedByte.length);
   }
   

4. Please pass your string inside this method and do what you want.
