Convert Base64 String to Bitmap

Introduction

     In android, Normally we send and receive data or image in the form of string.if we have receive image as base64 string you cant set into imageview.So here i made a simple function that you need pass base64 string and it will return a bitmap.later you have set into imageviews.

demo

Using this code

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent" >

<ImageView

android:id="@+id/imageView1"

android:layout_width="90dp"

android:layout_height="90dp"

android:layout_centerInParent="true"

android:src="@drawable/ic_launcher" />

</RelativeLayout>

Here is the procedure for converting string to bitmap but string should Base64 encoding

MainActivity.java

package com.example.base64tobitmap;

import android.app.Activity;

import android.graphics.BitmapFactory;

import android.os.Bundle;

import android.util.Base64;

import android.util.Log;

import android.widget.ImageView;

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

String base="****Base64 string values of some image******”;

byte[] imageAsBytes = Base64.decode(base.getBytes(), Base64.DEFAULT);

ImageView image = (ImageView)this.findViewById(R.id.imageView1);

image.setImageBitmap(

BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length)

);

}
