通过一上午的查询发现:Camera.Parameters.setPreviewFormat(PixelFormat.JPEG);这个方法生成作用的条件有必要是手机camara可以支持,否则是没有什么作用的。通过Listlt;Integergt;list=Camera.Parameters.getSupportedPreviewFormats();这个方法来判别手机支持哪种类型的PixelFormat,一般状况下是NV21即值为17.BitmapFactory.decodeByteArray这个方法是不能直接解析NV21格式的byte[],返回的是null,所以需求对NV21格式的byte[]进行转换.最终:sdk2.2提供了类YuvImage通过方法compressToJpeg进行转换,可是sdk2.1没有现成的api进行此操作(或者是说我没找到,找到了给说一下),所以需求自己进行格式的转换.本资料共包括以下附件:
