Android : How to show and encodeToString(base64) large image file on ImageView in android?

I try to sending and showing image file.But I can showing and encoding/decoding image about 50kb(lower than 50kb).But when I tried send/encode image(bigger than 100kb),I get an error."java.lang.OutOfMemoryError"

Uri selectedImage = intent.getData();

            String filePath=MediaOperations.getPath(getApplicationContext(), selectedImage);

            if (bmp != null && !bmp.isRecycled()) {
                bmp = null;
            }

            bmp = BitmapFactory.decodeFile(filePath);

I use this codes for getting file path.

I convert bitmap to byte array and byte array to base64string.And I'm sending basese64string to server with socketio.And I am show bitmap in ImageView.But base64 encoding doesnt work when file larger then 50kb.How can I solve this problem.?

I tried:

• android:largeHeap="true" but did not solve my problem
