Answer 1

I have put

mPreview.getHolder().removeCallback(mPreview);  

between.

mCamera.setPreviewCallback(null);

and

mCamera.release();

and it worked for me.

 @Override
            protected void onPause() {
                super.onPause();

                this.saveTextEdits();
                try {
                    mCamera.stopPreview();
                    mCamera.setPreviewCallback(null);
                    **mPreview.getHolder().removeCallback(mPreview);**
                    mCamera.release();
                    mCamera = null;
                }catch (Exception e){

                }
            }
