getRealMetrics

@Deprecated
@Implementation
protected void getRealMetrics(DisplayMetrics outMetrics)

Deprecated. This behavior is deprecated and will be removed in Robolectric 3.7.

If setScaledDensity(float) has been called, DisplayMetrics.scaledDensity will be modified to reflect the value specified. Note that this is not a realistic state.

getDisplayId

@Deprecated
@Implementation
protected int getDisplayId()

Deprecated. This behavior is deprecated and will be removed in Robolectric 3.7.

If setDisplayId(int) has been called, this method will return the specified value.

getRefreshRate

@Deprecated
@Implementation
