@Override Log.e(TAG,"I shouldn't be here"); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Method calls such as Log.e() should be in a method body. They cannot be directly in the class body. So, change it to something like this:

Log.e("I shouldn't be here"); With all this in mind, the closer your code gets to "production ready", the more you can restrict the base logging level for your code (you need V in alpha, D in beta, I in production, or possibly even W in production).

If you find log confusing you can create your own object ln that refers to the numpy.log function: >>> import numpy as np >>> from math import e >>> ln = np.log # assign the numpy log function to a new function called ln >>> ln(e) 1.0

I am using Java's Logger class. I want to pass ex.printStackTrace() into Logger.log(loglevel, String), but printStackTrace() returns void. So I am not able to pass and print the stack trace of the

You can use all your java classes from Kotlin, so Log.e( ) in java is exactly the same as Log.e( ) in Kotlin. If you want extra capabilities like automatically infering the tag string, you can use something like AnkoLogger

Specifying the exception as the message causes it to be converted to a string, which results in the exception message being duplicated.

2012年5月7日 · Instead of doing this you are advised using a logging framework (or a wrapper around multiple logging frameworks, like Apache Commons Logging) and log the exception using that framework (e.g. logger.error("some exception message", e)). Doing that allows you to: write the log statement to different locations at once, e.g. the console and a file ...

2015年2月10日 · Using Log.wtf is basically like using Log.e, only more severe. So this is not really an improvement over what the question already presents. The OP is trying to get logcat to show less severe log levels, D and V. –

Moreover, when you output a jQuery Object it will include a reference to that element in the DOM, and clicking it will go to that in the Elements/HTML tab.
