Converting base64 String to image in Android

Is there any way that I can convert a base64 String to image in Android? I am receiving this base64 String in a xml from the server connected through socket.

There are now Base64 utilities in Android, but they only became available with Android OS 2.2.

If you want to convert base64 string to the image file (for example .png etc.) and save it to some folder you can use this code:

byte[] btDataFile = Base64.decode(base64Image, Base64.DEFAULT);
String fileName = YOUR_FILE_NAME + ".png";
try {

  File folder = new File(context.getExternalFilesDir("") + /PathToFile);
  if(!folder.exists()){
    folder.mkdirs();
  }

  File myFile = new File(folder.getAbsolutePath(), fileName);
  myFile.createNewFile();

  FileOutputStream osf = new FileOutputStream(myFile);
  osf.write(btDataFile);
  osf.flush();
  osf.close();
} catch (FileNotFoundException e) {
  e.printStackTrace();
} catch (IOException e) {
  e.printStackTrace();
}

And make sure you have given the following required permission in your manifest file:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

After failing to get any solutions (even on Stackoverflow), I built a plugin that converts Base64 PNG Strings to files which I shared here. Hope that helps.

Have a look at http://www.source-code.biz/base64coder/java/ or any other example that converts base64 strings to byte-arrays, and then use the ImageIcon(byte[] imageData) constructor.
