MediaProjection gives error while getting screenshot for android Api<25

Question

I want to get screenshot of screen in android, I got screen shot as a Bitmap with using PixelCopy api for Api>=26 but I can not take screenshot for Api<25, When I try get screen shot of video I got black Screen, so I am trying to use MediaProjection get screen shot of device for Api<25. When I running below code I am getting this errror.

W/System.err: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.content.Intent.clone()' on a null object reference
