buildDrawingCache(boolean autoScale)
This method was deprecated
in API level 28.
The view drawing cache was largely made obsolete with the introduction of
hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache
layers are largely unnecessary and can easily result in a net loss in performance due to the
cost of creating and updating the layer. In the rare cases where caching layers are useful,
such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware
rendering. For software-rendered snapshots of a small part of the View hierarchy or
individual Views it is recommended to create a Canvas from either a Bitmap or
Picture and call draw(android.graphics.Canvas) on the View. However these
software-rendered usages are discouraged and have compatibility issues with hardware-only
rendering features such as Config.HARDWARE
bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback
reports or unit testing the PixelCopy API is recommended.

isDrawingCacheEnabled()
This method was deprecated
in API level 28.
The view drawing cache was largely made obsolete with the introduction of
hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache
layers are largely unnecessary and can easily result in a net loss in performance due to the
cost of creating and updating the layer. In the rare cases where caching layers are useful,
such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware
rendering. For software-rendered snapshots of a small part of the View hierarchy or
individual Views it is recommended to create a Canvas from either a Bitmap or
Picture and call draw(android.graphics.Canvas) on the View. However these
software-rendered usages are discouraged and have compatibility issues with hardware-only
rendering features such as Config.HARDWARE
bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback
reports or unit testing the PixelCopy API is recommended.

setDrawingCacheBackgroundColor(int color)
This method was deprecated
in API level 28.
The view drawing cache was largely made obsolete with the introduction of
hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache
layers are largely unnecessary and can easily result in a net loss in performance due to the
cost of creating and updating the layer. In the rare cases where caching layers are useful,
such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware
rendering. For software-rendered snapshots of a small part of the View hierarchy or
individual Views it is recommended to create a Canvas from either a Bitmap or
Picture and call draw(android.graphics.Canvas) on the View. However these
software-rendered usages are discouraged and have compatibility issues with hardware-only
rendering features such as Config.HARDWARE
bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback
reports or unit testing the PixelCopy API is recommended.

setWillNotCacheDrawing(boolean willNotCacheDrawing)
This method was deprecated
in API level 28.
The view drawing cache was largely made obsolete with the introduction of
hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache
layers are largely unnecessary and can easily result in a net loss in performance due to the
cost of creating and updating the layer. In the rare cases where caching layers are useful,
such as for alpha animations, setLayerType(int, android.graphics.Paint) handles this with hardware
rendering. For software-rendered snapshots of a small part of the View hierarchy or
individual Views it is recommended to create a Canvas from either a Bitmap or
Picture and call draw(android.graphics.Canvas) on the View. However these
software-rendered usages are discouraged and have compatibility issues with hardware-only
rendering features such as Config.HARDWARE
bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback
reports or unit testing the PixelCopy API is recommended.
