[RK3399][Android7.1] 调试笔记 --- 设置系统默认相机为1080p

Platform: RK3399
OS: Android 7.1
Kernel: v4.4.83

需求：
系统相机打开默认是1280*960，需要改成1920*1080

解决方法：

diff --git a/src/com/android/camera/settings/ResolutionSetting.java b/src/com/android/camera/settings/ResolutionSetting.javaindex 50ee90c..a99ae92 100644--- a/src/com/android/camera/settings/ResolutionSetting.java+++ b/src/com/android/camera/settings/ResolutionSetting.java@@ -143,7 +143,10 @@ public class ResolutionSetting {                 pictureSize.width() > 0 && pictureSize.height() > 0;          if (!isPictureSizeSettingSet || isPictureSizeBlacklisted || !isPictureSizeFromSettingsValid) {-            final Rational aspectRatio = ResolutionUtil.ASPECT_RATIO_4x3;++            //Kris,Use 1920*1080 as default preview size.+            //final Rational aspectRatio = ResolutionUtil.ASPECT_RATIO_4x3;+            final Rational aspectRatio = ResolutionUtil.ASPECT_RATIO_16x9;              OneCameraCharacteristics cameraCharacteristics =                     mOneCameraManager.getOneCameraCharacteristics(cameraId);

调用流程：

openCameraAndStartPreview ->   mAppController.getResolutionSetting().getPictureSize -> //获取图片的大小    getPictureSize -> ResolutionSetting.java      ResolutionUtil.getLargestPictureSize //默认如果没有设置,就会根据比例选择分辨率最大的一个  updatePreviewBufferDimension ->    mCamera.pickPreviewSize  -> 根据拍照图片大小选择对应的预览大小      pickPreviewSize ->  Camera2PreviewSizeSelector.java        CaptureModuleUtil.getOptimalPreviewSize
