For instance, optical character recognition is frequently excluded from things considered to be AI, having become a routine technology. Īs machines become increasingly capable, tasks considered to require "intelligence" are often removed from the definition of AI, a phenomenon known as the AI effect. ĪI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). This definition has since been rejected by major AI researchers who now describe AI in terms of rationality and acting rationally, which does not limit how intelligence can be articulated. The term "artificial intelligence" had previously been used to describe machines that mimic and display "human" cognitive skills that are associated with the human mind, such as "learning" and "problem-solving". AI research has been defined as the field of study of intelligent agents, which refers to any system that perceives its environment and takes actions that maximize its chance of achieving its goals. (And a bunch of other sub-debug constants for various aspects of it, since this file is ridiculously stupidly large.Artificial intelligence ( AI) is intelligence demonstrated by machines, as opposed to the natural intelligence displayed by animals including humans. This has those constants at the top, and various log lines sprinkled throughout based on them. For example, the Activity ManagerService.

This is the approach that a lot of the Android framework takes.
Basically just throw logs in wherever you need them and don't worry about leaving them in.

This is nice because it allows you to leave fairly extensive logging in your code to be turned on when you need it, without worrying about how that will impact the size of your shipping app. That makes sense for a small app, but as things get large it is nice to decide which parts to turn logging on.)īy doing this, when you build your app with DEBUG = false, all of your logging code not only isn't executed, but is completely stripped out of your app. (If you want, you could have one class with these statics for all of your app's code to use. Turn on your logs by changing the DEBUG constant to true. Now where you log, do this: if (DEBUG) Log.v(TAG, "Something") To do this, my recommendation is to put these constants at the top of each class that is going to have log calls: static final boolean DEBUG = false The issue is that the property values are lost after a reboot.Īn important goal is to not ship a production app with a ton of log calls left in it, increasing its size, and even possibly even impacting its performance. Using adb shell setprop VERBOSE also work. Later versions of Android appear to require that the permissions on the /data/local.prop file must be properly set, or it will not be read./data/local.prop is only read during boot.You can double check to make sure that the values in local.prop were read by executing: adb shell getprop | grep log.tag The former has no issues with reading a local.prop that is world writable, while the latter appears to silently ignore the file's contents.Ĭreating a local.prop file as described in the original question: _TAG=VERBOSEĪnd then pushing it onto the device as follows seems to do the trick: adb push local.prop /data/local.propĪdb shell chown root.root /data/local.prop I have only experimented with Android 2.3.3, and 4.1.2. Android, wisely, ignores /data/local.prop since this can be a security risk. The adb push command appears to initially create files with granting everyone read/write access (because default file mask is 777).
It seems that later versions of Android want /data/local.prop to be writable by root only.
