从logcat移除onFlyCompress消息 [英] Remove onFlyCompress message from logcat

问题描述

我正在使用YuvImage将android.hardware.Camera提要压缩为jpeg.从那时起，我一直在logcat中看到skia onFlyCompress消息，这完全污染了它.有什么办法可以禁用此消息?我知道我可以过滤logcat的输出，但这意味着可以一直在任何地方进行处理，这不是解决方法，而是一种解决方法.我就是根本不想打印这些消息

I am using YuvImage to compress the android.hardware.Camera feed to jpeg. Since then, I keep seeing skia onFlyCompress messages in logcat, which completely pollutes it. Is there any way to disable this message? I know I can filter the logcat output but that means doing it everywhere all the time, which is not a fix but a workaround. I simply don't want those messages printed at all

推荐答案

简短答案

尝试使用方法挂钩实现目标.

您可以使用 XPosed Framework 来挂钩android.util.log方法 在 ROOTED 设备上.

You can hook android.util.log methods using XPosed Framework on ROOTed devices.

详细方法

1. 使用XPosed Framework挂钩android.util.Log的方法.
2. 在挂钩方法中，检查邮件是否包含skia onFlyCompress.
3. 如果然后致电setResult(null);以防止其打印出日志消息.

1. Use XPosed Framework to hook the android.util.Log's methods.
2. In the hooking method, check if the message contains skia onFlyCompress.
3. If then call setResult(null); to prevent it from printing out the log message.

尽管，这些方法仅可在有根设备上使用，，但我希望我的回答至少对某些可以使用有根设备的用户有所帮助

Though these methods can only be used on rooted devices, but I hope my answer help at least some users that can use rooted devices.

(嗯，因为没有客户，您将不得不阻止日志消息，因此您要做的就是仅将您的本地设备仅作为根目录并安装使用XPosed框架的自动过滤应用.)

(Hmm, because no customers will have to block the log messages, so all you need to do is to just root your local device only and install the auto-filtering app that uses XPosed framework.)

要查看阻止方法执行其其余代码的示例: 此答案(尤其是最后一段)包含一些使用Xposed框架的示例.如您所见，代码非常短(不超过40行.)

To see an example of blocking a method from executing rest of its code: This answer(especially the last paragraph) contains some examples to use Xposed framework. As you can see, the codes are very short(no longer than 40 lines.)

如果需要/看到可能有用的代码，我将实施一些代码.

I will implement some codes if needed/seen potentially useful.

示例代码段

当有人支持我的建议时，我认为有人喜欢我的建议.所以我发布了一些代码.

As someone upvoted mine, I assume that someone liked my suggestions. So I post some codes.

import android.util.*;
import de.robv.android.xposed.*;
import de.robv.android.xposed.callbacks.XC_LoadPackage.*;

import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;

public class LogFilterApp implements IXposedHookLoadPackage
{

    private String TAG="LogFilter";
     public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable
{
    XposedBridge.log("Package name: " + lpparam.packageName);

            try
            {
                    findAndHookMethod("android.util.Log", lpparam.classLoader, "i", String.class, String.class, new XC_MethodHook()
                    {
                        @Override
                        protected void beforeHookedMethod(MethodHookParam param) throws Throwable
                        {
                            //do something before
                            if(((String)(param.args[1])).indexOf("skia onFlyCompress")>=0)
                                                          { 
                                                          param.setResult(null);
                                                           }
                        }
                    });
            }
            catch (XposedHelpers.ClassNotFoundError e)
            {
                XposedBridge.log("ClassNotFoundError");
            }
            catch (NoSuchMethodError e)
            {
                XposedBridge.log("NoSuchMethodError");
            }
        }
     }
   }
}
