I use eclipse to develop apps. When I goto eclipse's menu window->show view->other, I find two items nameed "LogCat" and "LogCat(deprecated)". What is the difference between LogCat and LogCat(deprecated)? I find when an application is running, they show the same logs.
LogCat was provided in ADT 4.0 or above, just add some new features. LogCat(deprecated) was the old version.
Deprecated means that at some point it will most likely stop functioning, you can still use whichever one you prefer until that happens .
I used both logcat and logcat(deprecated), and i did not found any difference except font and some details :)
Use of deprecated is the same like in any language. It's old and won't get support or won't have any improvement in that. In this case, theoretically Logcat should have or will have more/better features.

I was working on a project in android studio and suddenly I found a man type logo
I hover my mouse on in for a second then it shows me
Current Inspection profile: Project default.
Click to configure highlightening for the file.
When i clicked on this button it shows me
Now I want to know what is the use of this option or is this is important or not?
It may can be stupid question but I asked this question just to increase my own knowledge becuse this option seems bit important
Thanks In advance!
Happy Coding!
This has little to do with code inspection, but one can only define what is being highlighted. One could call it the visual representation of the inspection results, as it clearly read "highlighting level". This option only is of use, when you have to work with an old crappy computer, but rather irrelevant on current hardware.
As the name suggest, it inspects your code for issues, errors, incompatibility etc. and may recommends better options. If your system is low on resources (RAM, Battery, CPU) you can select None and also you can choose the PowerSave mode.
I have to estimate the time it takes to update a specific application made for Android 4.4 to Android 10 and I need to see all the methods that are deprecated or not working. Is there any way to see the methods without going file by file? (I'm using Android Studio with Java)
When I build the application I only get one or two types of error at a time, when I correct them I get another one and so on.
Thanks and best regards.
P.S: How long does it take you to update something like that? I'm a junior and I'm a little lost doing this.
Here, go to Analyze -> Inspect code. After inspecting check maturity there you will have depreciated methods. (Don't forget to change minSdk)
After you will do that it give you method with a warning and you can filter it by having API not support warning
I don't know about it completely. I think that it allows the deprecated code to be compiled. I want to know if the code under this line will always be run or not and does it depend on the software like Eclipse, studio you are working on?
Check this out.
Using suppresswarnings just tells the compiler not to warn you. It's still valid to use deprecated code, but usually there's a better way you should use instead.
The code will be compiled with or without it. It tells your IDE not to even warn you about it. Sometimes you have a good reason for using deprecated code. Putting this on those functions/classes reduces the number of warnings reported, which makes it easier to find important warnings of real problems.
Disables compiler warnings... In this case, deprecated code... Just for your information, for show clean code
few days ago, when I was debugging an Android project under eclipse I've found some great functionality: "All instances..." and "Instance count". I wanted to share my findings with rest of my colleagues, but none of them had this functionality in their eclipse install (we all use eclipse 3.7).
What's even more weird now I'm also missing this functionality.
As far as I can tell this functionality is build within eclipse from version 3.3 and available to projects using Java 1.6 and above as mentioned here and here (we're using 1.6).
See bottom of this link to see what functionality I'm talking about. It even has it's own shortcut in options (ctrl+shift+n) so I think there must be a way to use it again.
I was looking for it while debugging and while the debugger was in "stopped" state.
Anyone can help me put eclipse in right view/perspective/state to see this functionality again?
EDIT
Here is the documentation entry from eclipse help page: link
Thanks for any suggestions,

After some more digging I came to following conclusion:
DalvikVM does not support "instance retrieval".
On eclipse help page mentioned in EDIT section it written:
This command is only available if the Java virtual machine you are currently using supports instance retrieval.
Maybe there is an option to enable this option in DalvikVM, but I doubt it unfortunately.
Also when debugging on phone "Drop to frame" functionality is missing.
I've read the lame documentation, and checked other answers. I'd like my Android app to print some debug statements in the logcat window of Eclispe. If I use the isLoggable method on the various types of debug levels on the Log class, I find that WARN and INFO are returning true.
Log.w, and Log.i do not produce any output. Does anyone know which gotchas I've missed?
And just to vent, why should this be hard? I've published apps for iphone and bberry and while appreciate the use of java, the platform is reeking of too many "genuiuses" being involved. I suppose Activities and Intents are very flexible, but why? I just want to put up some screens, take some input and show some results. The bberry pushscreen and popscreen is a lot less pretentious.
Thanks,
Gerry
The problem with debugging with Android in Eclipse is that from Eclipse's point of view, you're debugging the emulator and not your specific app. The emulator isn't crashing, so there aren't any logs to show. What you need to use is LogCat, Android's debugging plug-in. See this answer for details on how to bring that up.
It is not clear to me what the problem is. I use "Log.d(TAG, "special message");" all the time in Eclipse in Android code running in the emulator. Since you say "Log.w" gives no output, I assume you already know about the need to import android.util.Log. Otherwise you would not have got even that far.
The only other thing I can think of is for you to check your Eclipse Preferences under Window>Preferences>Android>DDMS (DDMS is needed for Logcat). Make sure the timeout is reasonable (mine defaulted to 5000mS). Make sure the base local debugger port is open, too.
