android - returns - How to set a bitmap from resource

bitmapfactory.decoderesource returns null (4)

Assuming you are calling this in an Activity class

Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.image);

The first parameter, Resources, is required. It is normally obtainable in any Context (and subclasses like Activity).

This seems simple, I am trying to set a bitmap image but from the resources, I have within the application in the drawable folder.

bm = BitmapFactory.decodeResource(null,;

Is this correct?

I found this question when I wanted to set a bitmap to my View. For that reason, I found this code more helpful:


From here

If you have declare a bitmap object and you want to display it or store this bitmap object. but first you have to assign any image , and you may use the button click event, this code will only demonstrate that how to store the drawable image in bitmap Object.

Bitmap contact_pic = BitmapFactory.decodeResource(v.getContext().getResources(), R.drawable.android_logo);

Now you can use this bitmap object, whether you want to store it, or to use it in google maps while drawing a pic on fixed latitude and longitude, or to use some where else

Try this

This is from sdcard

ImageView image = (ImageView) findViewById(;
Bitmap bMap = BitmapFactory.decodeFile("/sdcard/test2.png");

This is from resources

Bitmap bMap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
