Share GlifPatternDrawable bitmap cache
Reduce memory usage of GlifPatternDrawable by
- Setting max bitmap cache scale to 1.5x (similar to
VectorDrawableCompat, which caps at 2048px)
- Use ALPHA_8 mask instead of ARGB8888
- Share the cache across all pattern drawables, using a SoftReference
The memory allocation of a single bitmap cache, measured on Pixel C,
dropped from 17MB to 2.3MB.
Memory consumption was measured in Android studio.
1. Open SetupLibrarySample app in Android Studio
2. Run app
3. Open "Android Monitor" tab, and go to Monitors tab
4. Press "Trigger GC" in Studio
5. Press "Start Allocation Tracking"
6. Start a new activity in the test app
7. press "Stop Allocation Tracking"
Test: ./gradlew connectedAndroidTest

[SuwLib] Implement pattern drawable background
- Implement the pattern background for GLIF using a custom drawable.
The drawable draws the paths manually as specified in the SVG, for
backwards compatibility.
- Use a FrameLayout subclass to draw the custom status bar background
in the case of phone layouts, and set draw the background directly
for tablet / clamshell layouts.
