| * Switch from FloatMath -> Math and Math.hypot where possibleNeil Fuller2014-10-011-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The motivation is an API change: FloatMath is going to be deprecated and/or removed. Performance is not the goal of this change. That said... Math is faster than FloatMath with AOT compilation. While making the change, occurances of: {Float}Math.sqrt(x * x + y * y) and {Float}Math.sqrt({Float}Math.pow(x, 2) + {Float}Math.pow(y, 2)) have been replaced with: {(float)} Math.hypot(x, y) Right now there is no runtime intrinsic for hypot so is not faster in all cases for AOT compilation: Math.sqrt(x * x + y * y) is faster than Math.hypot(x, y) with AOT, but all other combinations of FloatMath, use of pow() etc. are slower than hypot(). hypot() has the advantage of being self documenting and could be optimized in future. None of the behavior differences around NaN and rounding appear to be important for the cases looked at: they all assume results and arguments are in range and usually the results are cast to float.

* | Camera2: Final API revisionsEino-Ville Talvala2014-09-052-11/+11
| | | | | | | | | | | | | | | | | | - Rename listeners to callbacks. Listeners are single-method and are interfaces, while callbacks are abstract may get more methods in the future. - Use register/unregister for registering callbacks, not add/remove.

| | | | | | | | | | | | | | | | | | | | | | | | android.media.MediaCodec (createByCodecName|createDecoderByType|createEncoderByType) now explicitly throws IOException.

* | Add "throws IOException" to MediaCodec constructors (3)Andy Hung2013-11-053-5/+27
|/ | | | | | | | | | | | Change to add "throws IOException" to android.media.MediaCodec (createByCodecName|createDecoderByType|createEncoderByType). The exception was previously thrown through the native JNI, but not explicitly declared. Requires changes to existing code for declaration compatibility.
