Convert Image format in android java

Question

How do i convert Image format from within my android application activity.

I have the code to convert image format using Java, but it doesn't output the image with good quality and also similar code is not working in Android's Java.

Solution

You didn't post any of your code, so i have no idea what is wrong with your code. but you can convert a image to PNG or JPEG like this:

try {
   FileOutputStream out = new FileOutputStream(filename);
   bmp.compress(Bitmap.CompressFormat.PNG, 100, out); //100-best quality
   out.close();
} catch (Exception e) {
   e.printStackTrace();
}

here is my code in android, but where do i put my original image url 'public class Main extends Activity { Bitmap bmp; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); try{ FileOutputStream out = new FileOutputStream("jjj.jpg"); bmp.compress(Bitmap.CompressFormat.PNG,100,out); out.close(); } catch(Exception e) { e.printStackTrace(); } } }'

It depends on which image are you pretending to convert? do you have it in your phone, do you receive it through internet... ?

[Guillermo Merino]

You can use Bitmap bm = BitmapFactory.decodeFile(yourPath);

[Shubham Naik]

so BitmapFactory.decode() will initialize my Bitmap object to the image, is it correct?
