I just finished my last app and after intensive testing on android studio no bugs or errors pooped up.
But when I use my phone for some time and try to check my app it crashes, and error pops up.
Is there a way to find out the stack trace od that error? specially since its not connected to my PC.
You can integrate tools for analyse, like:
Crashlytics
So you have a dashboard and can setting a e-mail for warning.
You can use different options:
Store logcat file in Internal memory as txt file. This will be best solution since it will provide all the necessary information of pre-conditons for the crash
Implement crashanalytics like Hockeyapp
Use remote debugging. Refer this official document for more info
You can find more details for approach 1 & 2 at: remote logcat - Android Studio

I have a MAUI app on Android which works perfectly when launched from Visual Studio with the debugger attached. If I published an APK and install it on the device manually, the application crashes as soon as I use the AppShell to change the current page.
How can I attach the debugger to it after I've launched it manually? Failing that, just finding a way to see a stack trace for the unhandled exception would be a big step forward.
I tried capturing a bug report and reproducing the crash, but the report did not appear to contain any account of crash. I was unable to find any crash dump logged by the OS, but this is my first Android app, so I might be missing something there.
Thank you #jan-joneš, you set me along the right path. Although it's outdated with respect to MAUI, I found a useful page in the Xamarin documentation with more tips.
It would be so much easier if these exceptions were flagged by the debugger!
I've seen plenty of ways of getting system logs in Android with logcat and the like, but not so much about app logs (except for the usual USB + adb solution).
My B2B Android app produces useful logging created with Log.i calls. Whilst in Studio these are very useful for debugging, it would also be useful to get these from customer's installs when things go wrong, i.e. from a release build out in the wild. Customers are generally not techies so getting logs via adb isn't really an option.
Is there a way within the app code itself to grab all the log contents?
Perhaps the SDK provides a way to do this?
I could then send that to my server or by email. I'm thinking it'll be useful for my customers to just hit a button so I can get an instantaneous snapshot of what is happening in the app.
Thanks in advance
UPDATE
There doesn't seem to be a way to do this, aside from writing to a file and sending that file. Which I guess is a good a solution as any.
Two other interesting ones that have come up are:
Firebase (from Mohammed's comment) - can log events:https://firebase.google.com/docs/analytics/android/events
Instabug
we can write write logs to file using java.util.logging.Logger API.

I'm trying to create a (root) app in /system/app, but having an issue that I can't resolve without seeing some errors and debugging to see exactly where it's going wrong.
If I run from Eclipse, errors are expected however, as the app won't have appropriate permissions.
How can I run a local (/system/app) installation, and somehow see what's going wrong?
Can it be done from Eclipse? I had a look at this - but it's so poorly formatted I couldn't make sense of it. If it can't - is there some way to print errors as text?
I am working on a game in eclipse. I connect my android phone to test my game application. Upon pressing "RUN" in eclipse, the game will begin to be uploaded to my device. However, it onl makes it half way then the console in eclipse gives me this error: INSTALL_FAILED_INSUFFICIENT_STORAGE. I checked my internal storage and I have 30mb left. My game is 3.20mb. I should have plenty of room. shouldn't I? Is this just a bug?
ps. This is very frustrating to me. I go to google developer forums and they tell me that if I am a neebie, to post on stackoverflow. I post on stackoverflow only to find they migrate me to SuperUser. Then SuperUser says, you were supposed to post on Android Enthusiast (beta), and migrate me there. Finally, I just looked, and someone posted that my question belongs on STACKOVERFLOW!!! Now I am back where I started. I am just trying to get some answers. Could someone please help me instead of migrating me please?
My application had a special german character in it,
like
"ö,ä,ü ... ß" .... (it was ö), prohibited adb to deploy the apk file no the device.
-> resulted in this error message...
so check your project name.
good luck!
How can I read the error log applications make? Is there any software which reads the error log from the handset and displays it?
I don't want to debug the app using eclipse, I'm looking for a handset based error log viewer.
There are a number of free applications in the Android Market which will collect the device log.
One which looks promising is Log Collector, not least because it is open source. You can find it on Google Code here and on androlib.com here.
Here's another Log Collecting app produced by the creators of Locale.
I quite like the one I wrote ;-)
It's called SendLog

Alogcat seems OK. It's a bit verbose, though.
