java Android smali edition：设置jpeg质量？
大家好，这里的开发者们
最近，我修改了ColorOS摄像头的一个端口，使其能够在我的设备（小米Mi4）上工作。 实际上，这个应用程序只适用于XML版本。但问题是，这个应用程序使用默认的安卓 jpeg压缩（在我的例子中，jpegquality=85%）
我刚刚决定修改smali文件来改变这个。我已经修改了突发模式以捕获100%质量的jpeg（将值0x4B更改为0x64以获得100%的质量，而不是突发模式下的75%，并且工作正常） 当我试图编辑其他行以获得jpeg质量=100%时，即使在正常拍摄模式下，问题也会出现
有人能帮我解释一下吗？（请不要忘记我是个初学者，我花了很多时间尝试编辑）
以下是smali代码（来自CameraProcessManager.smali）
.method public setCaptureJpegOrientationAndQuality(I)V
.locals 4
.param p1, "orientation" # I

.end method
下面是相应的java代码（我知道我不能编辑由smali编写的java代码，遗憾的是，这会更容易） 从dex2jar：
public void setCaptureJpegOrientationAndQuality(int paramInt)
{
this.mJpegRotation = paramInt;
if (this.mbBurstShot) {}
for (paramInt = 75;; paramInt = CameraProfile.getJpegEncodingQualityParameter(this.mCameraId, 2))
{
this.mParameterManager.setRotation(this.mJpegRotation);
this.mParameterManager.setJpegQuality(paramInt);
Log.v("CameraProcessManager", "setCaptureJpegOrientationAndQuality(),mJpegRotation:" + this.mJpegRotation + " jpegQuality:" + paramInt);
return;
}
}
下面是德德十工作室的另一个观点：
public void setCaptureJpegOrientationAndQuality(int i)
{
mJpegRotation = i;
int j;
if (mbBurstShot)
j = 100;
else
j = CameraProfile.getJpegEncodingQualityParameter(mCameraId, 2);
mParameterManager.setRotation(mJpegRotation);
mParameterManager.setJpegQuality(j);
Log.v("CameraProcessManager", (new StringBuilder()).append("setCaptureJpegOrientationAndQuality(),mJpegRotation:").append(mJpegRotation).append(" jpegQuality:").append(j).toString());
}
我希望保留JPEG定位设置，但将JPEG质量更改为始终100%
如果有人能够帮助我并给出一些解释，请提前多谢=）
