[Android] How to get image file from assets & set bitmap to canvas.

 

 

 

 

 

Bitmap assetsRead(String file) {
        InputStream is;
        Bitmap bitmap = Bitmap.createBitmap(previewWidth, previewHeight, Config.ARGB_8888);

        try {
            is = getAssets().open(file);
            int size = is.available();
            byte[] buffer = new byte[size];
            is.read(buffer);
            is.close();
            bitmap = BitmapFactory.decodeByteArray( buffer, 0, buffer.length ) ;
            bitmap = Bitmap.createScaledBitmap(bitmap, 720, 720, false);
        } catch (IOException e) {
            e.printStackTrace();
        }

        return bitmap ;
    }

int width = canvas.getWidth();
int height = canvas.getHeight() / 2;
Bitmap resize_bitmap = Bitmap.createScaledBitmap(assetsRead("image.png"), width, height, false);

canvas.drawBitmap(resize_bitmap, 0, 0, null);
