@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).

2016年7月28日 · I have used Log.d() and Log.e() through out my android application for debugging purpose. I would like to know if I release my application like this, will the user sees all those debug statement that I put in? Do I need to do something special so that user won't see the debug log even if they hook up 'adb logcat'? Thank you.

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

2016年4月22日 · Using PowerMock one can mock Log.i/e/w static methods from Android logger. Of course ideally you should create a logging interface or a facade and provide a way of logging to different sources.

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

2010年2月22日 · O(log n) is a bit misleading, more precisely it's O(log 2 n), i.e. (logarithm with base 2). The height of a balanced binary tree is O(log 2 n), since every node has two (note the "two" as in log 2 n) child nodes. So, a tree with n nodes has a height of log 2 n.

Log.wtf() might call onTerribleFailure() and can cause termination of your application. COMMON MISTAKE. Official docs say: Log.e() logs with priority ERROR. However, Log.wtf() logs with priority ASSERT. ASSERT has priority constant = 7 ERROR has priority constant = 6. So Log.wtf() has higher priority with respect to Log.e()

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

2014年4月26日 · I'm trying to make a loglog plot on a natural log scale. But after some googling I cannot somehow figure out how to force pyplot to use a base e scale on the axes. The code I have currently: import matplotlib.pyplot as pyplot import math e = math.exp(1) pyplot.loglog(range(1,len(degrees)+1),degrees,'o',basex=e,basey=e)
