这些信息不间断的打印，将与程序相关的有用信息淹没。如何关闭这些没用的信息。

解决方案

不是可以通过添加filter 打上logtag把不属于tag的过滤掉吗？

解决方案二：

有没有解决？我也是这样

解决方案三：

1，用过滤器是一个很通用的方法，可以过滤出自己需要的指定的信息。
2，Window---Preferences---Android---logcat--取消第一个选中，
在调试中，向下的箭头也取消选中就行了

解决方案四：

大家好，这个问题我以前也遇到过，设置步骤：windows---preference---左侧栏点开Android----Logcat----看到右边第一行的输入框，有的版本默认是0，有的是5000。（0就代表默认值5000，意思是Logcat默认打印5000条信息，超出后，之前打印的就会被覆盖掉），真机也在运行其他程序，所以我们想要看到的logcat信息很快就会被覆盖。
在默认值输入框里，输入一个比较大的数字就可以了，比如几十万、几百万等，都能有效解决大家的问题。

解决方案五：

真机调试Android项目，logcat不断不间断的打印无用信息将有用信息淹没 ，这个是因为你使用了真机，你用genymotion模拟机就可以了，就不会有了
