This just started happening recently and it has gotten progressively worse. I was initially alerted when I saw a couple calls to the Facebook API when my app had nothing to do with FB whatsoever.
Things I tried that (temporarily) helped:
- Closing all tabs in Chrome
- Closing all open applications
- Selecting "Show only selected application" option
Note. My app isn't even running. This happens as soon as I open Android Studio and plug my phone in. I get roughly 1,000 log/30 minutes.

Your selecected filter Show only selected application will only work if a process is selected. Just select your process when your app is running where it currently says No Debuggable Processes.
The output shown in your screenshot is the log of the whole device, including logs of the system and other apps.
Logcat shows logs in general, so if you want to see just specific app, you got app filter above the list. Also theres text filter if given app is too noisy as well

Environment
OS: Android10
Model: Huawei Honor 10
SDK: hwid 5.0.4
Problem describe
Test brid report there are black screen found in our app with few specific devices.
As we reproduced, the black screen happen after we called Huawei login method. And black screen is disappear after we click Android back button.
useful info
As we dig into, the top activity that make screen black is com.huawei.hwid20.inputrealname.InputRealNameActivity, and more, as we search in the logcat, we found following lines that you may interesting:

So we think the SDK was trying to remove InputRealNameActivity but failed due to exit animation.
In our brain storm opinion, we are thinking some animation play failed due to device issue, and this failed animation prevent the destroy of InputRealNameActivity, so it leaves in the screen.
Anyway what we can confirm is, an Activity InputRealNameActivity from huawei SDK do make the screen black, and users may have no idea how to cancel it, it hurts our user experience and I believe it hurts Huawei's user as well.
Reproduce
As what we know, it is not a common case, so you can not produce it easily, luckily we found a device in test brid could reproduce it.
enter here, https://www.testbird.com/ , login, and search for Huawei Honor, you'll find there is only one Huawei Honor 10 device, that device could reproduce it easily. Just run the app, and tigger Huawei account login.
Thank you in advance, if the team could take a look about this issue.
According to the team, this issue is caused by security considerations.
The screen recording prevention and screen capture prevention functions are provided on the account login page. Then the device in test brid may have triggered this security mechanism, so it goes black screen.
New to flutter/mobile development. Had to do a bit of R&D to get what i need in a mobile app, I'm stuck at the very end of the finish line. i.e making my .apk work on the actual device.
I've tried installing app with flutter install and by transferting build\app\outputs\apk\release\app-arm64-v8a-release.apk on to my device.
App get installed successfully, but crashes immediately on the start.
On the other hand It builds and runs fine with flutter run, on both emulator and on physical device (s10+)

Update 2
While searching online i've found that similar issue happened if you are using a third party lib and try shrinking the build.
I'm using msal_mobile for authenticating user at the beginning. If i don't shrink my build
flutter build apk --no-shrink
Now the app works and doesn't crash.
On the other hand if I avoid the following msal_mobile initializing code, and build the apk with shrinking enabled flutter build apk, which uses R8 to shrink, app doesn't crash again.
class _MyAppState extends State<MyApp> {
MsalMobile msal;
#override
void initState() {
super.initState();
MsalMobile.create('assets/auth_config.json', "https://login.microsoftonline.com/Organizations").then((client) {
setState(() {
msal = client;
});
});
}
}
Is there some different approach to shrink the app when u are using lib that causes such issue.
I encountered the same error and narrowed the problem down to the msal_mobile package having issues invoking platform-specific functionality with its method channels (specifically Line 39 of msal_mobile.dart).
Based on what I read here, it seems like the Android modification and obfuscation process ends up being a bit overzealous when renaming methods, making the method channels used in the msal_mobile package think that the method they are trying to call doesn't exist.
The only solution that I found to work for my own situation isn't ideal, as it increases the size of my app, but it got my project working again, so I thought I would share.
In your project's directory, open the file android/app/build.gradle and add the following lines to the release section of buildTypes:
buildTypes {
release {
signingConfig signingConfigs.debug
minifyEnabled false // Add this line
shrinkResources false // Add this line
useProguard false // Add this line
}
}
I hope this helps a bit!
I am using 2 build environments in parallel: Windows and Ubuntu.
When I build APK in Windows (via command line) - the APK is fine and runs great.
But when I build exactly the same project on Ubuntu - it fails (running on the same Android device).
I clone the project from the same git repository, and during the gradle build - I receive the one-to-one same messages.
Have no idea where I should start digging.
Any advise will be appreciated.
BTW, I have run-time logs from both APK's:

I am developing an android application in which I have 2 Activities. When I am running this application on devices it runs perfectly but when I am running it on MI TAB-2, when on activity-2, after a specific time it crashes automatically and restarts from activity-1. It does not crash at same instant, just anywhere in application. It is not giving any error or warning on LogCat. I am not understanding what's the exact issue it is having. Is there any way using which I can figure out the error?
P.S. In this device, Google Play Store also crashes in same behavior.

This is what I am getting in LogCat
I'm new on eclipse and android and I want for my first app do a wifi connection between the smartphone and an ip camera, unfortunately my app crash if when I want to see the stream of the camera.
My logcat said that:

03-06 18:11:26.879: E/(680): error : 2, No such file or directory
