There seem to be too many bugs which have not been properly documented, regarding android studio. I am trying to run a basic Hello world app, and this error is truly making me give up any more efforts.
What I did:
Open Android studio(also tried running as administrator) and tried to run the default Hello world app on an Android 10 device(Xiaomi). At the start it shows Failed to start monitoring 7D8XXCOJGQQCZLJV(device number). At first I ignored it being a beginner and clicked on the run button. The file was successfully built and the RUN section shows 'Install successfully finished'.
Now for clarity here are some screenshots that will display what happened on my android device after the above steps:
The app seemed to be installed correctly, but whenever I click on the app logo the response I get is really frustrating:
As per the this link I tried to go to the device manager and do some changes, by setting and enabling Xiaomi drivers for Portable devices.
But then windows shows:
If anybody knows how to solve this, please do help me in doing so. It is quite discouraging to experience so many errors, right at the beginning. If somebody could give a working solution then that would really help me in continuing my android journey.
There was just a tiny error that led to this entire problem. This was because I had set the value of android:exported="false" in the main activity, which had to be set to true. Hope that this may help anybody in the future!
set the value of android:exported="true" in the AndroidManifest
I know this may have been asked here before, but still didn't get any solution. I have closed logcat and reopened it, closed eclipse then restarted it, nothing helps. This was working perfectly before but suddenly I found out that logcat not showing messages of my apps anymore, it is showing device messages only. I use a spice mobile device instead of emulator, at first I thought it can be a problem related to device, but then tried the same with android emulator and same thing happened. What have gone wrong? What should I do now?
Create a filter for your app using the package name.
Eclipse do it automatically when you launch your app, but it fails sometimes.
Hope this helps.
Can u see these? Try Android Studio.
images to all messages!
My problem is, that I can't seem to deploy my app to my phone (galaxy s4) or the emulator anymore, after adding the AndroidManifest.xml to the project.
I have been working on this app for 1 or 2 days, never had a problem testing it on my phone. I wanted to add the App Icon and change the app display name and found out that it had to be done over the AndroidManifest.xml file. So after finally finding where to add it in the QtCreator, I added an Icon and changed the name. When I click deploy, it loads and then the bar turns red, without ANY error messages or nothing. It just goes red full and then goes away. Even the warnings from build are not even showing.
I hope you guys can help me, this is my first question, so if I forgot any information or asked the question wrong, please let me know :)
You need dirqml2sdk debugger libaries (if your OS is windows). You can download it from here.
Okay, let me first apologize by saying this is my first post on stackoverflow and haven't been coding that long so this may be a simple error on my part. Also let me thank you ahead of time for trying to help me. So this is basically what is ailing me, I have a app i have coded that is used to set wallpapers on android phones and recently have been submitted to blackberry's appworld.
I have never had any issue with the app until the other day when all of a sudden when i changed the package name to a new one. Note this is of a fresh install of the app. But for some reason the Blackberry Z10 is opening the app for about a second and shows me a black screen for less then a second and then close. However, my eclipse's logcat states otherwise and that it is still loading. Note that I have other apps using the same setup and library as this app and also have recently changed their package names and haven't run into this problem. Also this only happens on Blackberry Phones and doesnt give me this issue on any normal android phones.
Here is my logcat: http://pastebin.com/EzD6eQaU
If you have any idea why this is happening please let me know.
Thank you again,
Dalton
It took a while but i found out what was my issue. Blackberry has a package name character limit of at least 50 characters long. Any more then that and your app wont work on blackberry.
Unfortunately appname has stopped, while I am using main activity for both androidmanifest.xml file and for the Java file, so there is no chance of using different activities, but still i am getting this message,like:
Unfortunately LunchList has Stopped.
I am getting this when I am making simple Android app with SQLite database, RSS Reader and much more, but the thing is my codes are working fine because not showing me an error of coding and I am able to run and debug my apps. I am also getting problem with option menus like sometimes menus are not coming, sometimes they are coming but not responding.
but the thing is my codes are working fine because not showing me an error of coding
You mean it's compiling? That's not the same as working. Clearly your code isn't working, otherwise it wouldn't be crashing like this.
You should look in your application's log file (e.g. with logcat). I'm confident it will show you an exception, with a stack trace. That should give you a good idea of what's going wrong, and where it's going wrong. If you find out what's going wrong but don't understand why it's going wrong, that's a reasonable Stack Overflow question in itself, but the first thing is to get that initial diagnostic information.
Note that if you run your app in the debugger, I'd expect that if this error occurs, the debugger should stop to show you where the problem is. (I've never built an Android app, so I can't swear that's the case, but it's a reasonable expectation.)
When you encounter a FC ( Force Close ), You should monitor your application. In Eclipse open the DDMS view and monitor the application with logcat. and see what causes the problem!
