有时我们需要在程序执行进程中遇到一些异常,需要收集一logcat的信息,android下就可以使用以下方法获取:

private static String getLogcatInfo(){
String strLogcatInfo = "";
try{
ArrayList<String> commandLine = new ArrayList<String>();
commandLine.add("logcat");
commandLine.add( "-d");
commandLine.add("*:E"); // 过滤所有的错误信息
ArrayList<String> clearLog = new ArrayList<String>(); //设置命令 logcat -c 清除日志
clearLog.add("logcat");
clearLog.add("-c"); Process process = Runtime.getRuntime().exec(commandLine.toArray(new String[commandLine.size()]));
BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(process.getInputStream())); String line = null;
while ((line = bufferedReader.readLine()) != null) {
Runtime.getRuntime().exec(clearLog.toArray(new String[clearLog.size()]));
strLogcatInfo = strLogcatInfo + line + "\n";
} bufferedReader.close();
}  
catch(Exception ex)
{
process.destroy();
}
return strLogcatInfo;
}
