I am using Android Studio 1.5.1 IDE.
I plugged up a Samsung phone to test with. Without even running the application I am testing, the LogCat constantly just scrolls data and it makes it difficult to focus on my app.
Is there a way to stop the console from showing phone debug logs and just show me my app when I am running it?
Yes, when running the application you are able to select your application in the dropdown highlighted in green here:
This causes only the output from that specific application to be shown during debugging/running.
If you're asking to never ever show the logs from your phone, I cannot help you with that.

Simple question, but is it possible to view the entire logcat output of an Android device in Android Studio? Meaning all of the logs from everything that's happening on the device, not necessarily only those generated by the app in development.
I ask because I have a bug that does not show up on the debug build (i.e. I build it in Android studio and run it on a device), but it DOES show up in the production build for the same code, and I would love to see what is happening on the device.
Essentially, I'm asking if it's possible to select nothing from the following dropdown menu.
Use no filters option in your Android studio Logcat.
How you can select nothing in processes spinner:
Stop your application
Close the emulator
Press launch in android studio
Cancel launching the application
Emulator is still launching
You have no debuggable processes in your spinner.
I've been working with PhoneGap for about two weeks now, yesterday I've build a new android app all went well except that the app starts very slow on my android device. It first shows me for three seconds just a black background except the navbar. So I want to ask how to boost it up or which files I could remove or what I've done wrong please I would be happy if you explain me also the file structure. Thanks in forward for your answers!
Your question is little bit vague. Please, give us more information about your app, about your config and what you’ve already tried.
If my app is slow on any device, I do generally the following:
Check if the same problem occurs in the browser
What’s going on at the start of the app in the browser (Chrome Dev Tools)
If nothing unusual happens, check the logs on the device
For Android, I’m using Logcat for checking what’s happening on the phone.
In order to use Logcat:
1.) Enable debugging mode on your Android phone
2.) You need Android Studio
3.) Connect your phone to your computer and start Logcat in Android Studio 3.1.2
4.) Check the logs while you are starting your app on the phone
It is not really a programming question. I have this app that continues to crash on my phone, but works fine for everybody else. I used to program android apps, so I have knowledge in this field.
It something on my phone probably it always crashes at the same stage. I did not program this app. How can I still get the details of the error or the trace of the exception?
I would suggest plugging the phone into your computer or laptop, opening up the Logcat tab in Android Studio and viewing the exception details as the app crashes.
This can be done separately from Android Studio using ADB but it involves more steps.
Of course, make sure that you have enabled USB debugging on your device before this.
I am very upset about the Android Logcat.
I don't see errors when i run app from my phone.
Logcat doesn't show anything when i try to run an app, but then the app freezes on my smartphone and shuts down.
I cannot develop if logcat doesn't show me any error at all.
If the app runs corretly it will show up.
Things i did to try see an error in Logcat while developing:
Restarted computer
Restarted Android studio
Cleared every single filter from the Logcat in Android Studio
Executed adb kill-server
Uninstalled an application that i developed
I am very confused. I need to see a Logcat error to continue developing my application. At the moment i cannot continue developing. Please help me out of trouble!
Things i havent tried yet:
Reset my phone to factory settings
Have you tried to go to the device tab (where the devices and emulators are), click your device and then go to the logcat tab again?
I've got an app inventor app built and working pretty well in the emulator. When I put it on my phone none of the code runs. The app doesn't crash, but the code behind the objects doesn't do anything. I've got code which runs on screen load which doesn't fire, and my buttons don't do anything.
The drop downs show the menu item, but that's it.
Does anyone have any ideas?
Have you connected the phone with the Block Editor Open? Can u see live preview of the app being developed?
You need to install a small application "AppInventorPhoneApp" to the phone in-order to accomplishing this... Usually this will be installed when you connect the phone first time with your BlocksEditor...
Just connect the phone to the Blocks Editor. Blocks editor will automatically install this application. Then you can see the preview in Phone.
Click Download apk from app inventor. Then Click, Package for Phone--->Download To Connected Phone.
I hope this solves your issue.
Check if unknown Sources and Development options are turned on in the Application settings.... For an application to run without these, you have to sign it. (I am not sure about this)..
