如何读取过滤日志的猫，其中等级是警告？

这是我所知道....

 的logcat =调用Runtime.getRuntime（）EXEC（新的String [] {的logcat，D}）;

BR =新的BufferedReader（新的InputStreamReader（logcat.getInputStream（）），4 * 1024）;
串线;
  最后StringBuilder的日志=新的StringBuilder（）;
  串隔板= System.getProperty（line.separator）;
    而（（行= br.readLine（））！= NULL）
     {
       log.append（线）;
         log.append（分隔符）;
}
 

解决方案

-s标志，可以筛选logcat的输出基于标签和水平E，W，D，V，所以你可以尝试修改您的线路。

 的logcat =调用Runtime.getRuntime（）EXEC（新的String [] {的logcat，D， -  S，*：W}）;
 

How can i read filtered log cat whereLevel is Warning?

That's all i know....

logcat = Runtime.getRuntime().exec(new String[]{"logcat", "-d"});

br = new BufferedReader(new InputStreamReader(logcat.getInputStream()),4*1024);
String line;
  final StringBuilder log = new StringBuilder();
  String separator = System.getProperty("line.separator"); 
    while ((line = br.readLine()) != null)
     {
       log.append(line);
         log.append(separator);
}

The -s flag lets you filter logcat output based on tag and level e,w,d,v so you can try modifying your line.

logcat = Runtime.getRuntime().exec(new String[]{"logcat", "-d","-s","*:w"});
