Android12第三方应用预览模糊解决

   平板安装百度，在百度搜索里面使用相机，相机预览特别模糊，应该是百度没有适配平板导致，查看log，02-08 17:29:12.275: I/MtkCam/TPI_S_FB(793): [getConfigSetting] max out size(1920x1088), StreamingSize (1920x1424), AllSensorSize is 1, first sensor is 0, Timestamp: 242494345782   qq浏览器的相机预览

百度的相机预览

和qq对比百度的预览尺寸太小，所以改预览尺寸就可以了，
