本文介绍了Android Log.X不打印stacktrace的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
e.printStackTrace()可以正常工作(即将我的堆栈跟踪信息打印到stderr),但是Log.X根本无法打印堆栈跟踪信息.
e.printStackTrace() works fine (i.e. prints my stacktrace to stderr) but Log.X fails to print a stacktrace at all.
例如:
} catch (IOException e) {
Log.e("Network", "Exception", e);
e.printStackTrace();
}
输出:
08-31 03:46:21.992: W/Network(13238): Exception
08-31 03:46:22.092: W/System.err(13238): java.net.UnknownHostException: Unable to resolve host "...": No address associated with hostname
08-31 03:46:22.204: W/System.err(13238): at java.net.InetAddress.lookupHostByName(InetAddress.java:394)
08-31 03:46:22.222: W/System.err(13238): at java.net.InetAddress.getAllByNameImpl(InetAddress.java:236)
08-31 03:46:22.222: W/System.err(13238): at java.net.InetAddress.getAllByName(InetAddress.java:214)
推荐答案
显示出Log.X使用的Android Log.getStackTraceString吞噬UnknownHostException. :(
Turns out Android's Log.getStackTraceString which is used by Log.X swallows UnknownHostException. :(
来自:
public static String getStackTraceString(Throwable tr) {
if (tr == null) {
return "";
}
// This is to reduce the amount of log spew that apps do in the non-error
// condition of the network being unavailable.
Throwable t = tr;
while (t != null) {
if (t instanceof UnknownHostException) {
return "";
}
t = t.getCause();
}
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
tr.printStackTrace(pw);
return sw.toString();
}
一切都很好,可以减少日志记录,但是甚至不告诉我,我的例外是不好的joojoo!
It's all very well reducing log spew but to not even tell me what my exception was is bad joojoo!
