View full v1.0.5 changelog (large release)

Core & Threading

• Fix: Modified BlurNative.java to use a static, shared ExecutorService
• Skip thread overhead for single-core devices in the Java layer
• Performance: Moved PixelCopy operations to a dedicated handler thread

API Additions

• Added setDownsampleFactor(float) method and corresponding app:downsampleFactor XML attribute

Blur View Rendering

• Updated blur view components to handle overlapping scenarios
• Fixed resource leakage in BlurNative; changed to a static shared instance to avoid repeated instantiation
• Replaced VLA with heap allocation in native code to prevent stack overflow
• Removed unnecessary alpha channel clamping in blur calculations

SurfaceView Support

• BaseBlurView now automatically detects SurfaceView and calls setZOrderMediaOverlay(true) to ensure proper Z-ordering for blurring
• Added informative logs when a SurfaceView is configured, with warnings for potential issues (e.g., API level < 24)
• Added check for SurfaceView surface validity before attempting PixelCopy to prevent crashes
• Enhanced error handling for PixelCopy failures, including retries for transient errors like ERROR_SOURCE_NO_DATA
• Added detailed logging for PixelCopy success and failure states to aid debugging

Glide Integration

• Added com.qmdeve.blurview.transform.glide.BlurTransformation implementing BitmapTransformation
• Supports BitmapPool for efficient memory management and correct disk cache keys
• Supports configurable blur radius and rounded corner radius

Picasso Integration

• Added com.qmdeve.blurview.transform.picasso.BlurTransformation implementing Picasso’s Transformation interface
• Properly handles Bitmap recycling
• Supports configurable blur radius and rounded corner radius

Error Handling & Robustness

• Added empty check to Glide’s BitmapPool.get() call for enhanced robustness
• Improved error handling and debugging logic throughout

Layout & Measurement

• Fully rewrote measurement logic to correctly handle margins and size measurements for subviews
• Added support for android:layout_gravity, allowing subviews to be precisely positioned within a parent container
• Fixed sub-view layout positioning limitations from the previous version
• Added LayoutParams type check when measuring subviews; automatically converts and sets back if the type is incorrect
• Ensured all subviews use the correct LayoutParams type
• Re-measures only when available space differs from the current measurement size (avoiding unnecessary work)
• More accurate handling of FILL_HORIZONTAL and FILL_VERTICAL gravity values
• Corrected sub-view position calculation logic
• Safer boundary inspection to ensure subviews do not exceed the bounds of the parent container
