在代码中读取logcat中的日志

 不要放到UI线程中去执行，直接上代码

    try { 
    	Process process = Runtime.getRuntime().exec("logcat -d"); 
    	BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream())); 
    	StringBuilder log=new StringBuilder();   
    	String line = ""; 
    	while ((line = bufferedReader.readLine()) != null) { 
    		log.append(line); 
    	} 
        Log.e("log", log.toString());
    } catch (IOException e) {
    	
    }
