Running the first Hello World Application (Kotlin)

[Zulfi Khan]

Hi,
I tried to run hello world program using tutorial kart. The link is:
Android Programming usingKotlin Tutorial

It does not ask to write any code nor does it ask for altering any built in code. I ran it by connecting both by mobile phone and using emulator.
Error log when connected to mobile ph:
“Session app” Error installing APK

import android.os.Bundle

class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
}
}
   

Some body please guide me.

Looks like from the supplied stacktrace that issue you are experiencing is related to "Instant Run".
You do not need to have this feature enabled and some devices do not.

You stated that you ran this on both an emulator and a physical device, what versions of Android were you running?

You may not be aware of this, but Google supplies free tutorials on Android development which can be found here https://developer.android.com/guide/.
Google has supplied not only the instructions on how to get started, but usually the code needed and a functional sample project.
You may need to update the project to use newer versions of Gradle, but the process is the same for all of the projects that need it.

Google has even provided Kotlin code and project resources.

I just noticed this line:Error log file while running using an emulator (visual studio android 23 arm ph) Are you using Visual Studio when following along with the tutorial that you initially posted?
If there, there very well could be an issue with Visual Studio and you may get better/different results with Android Studio.
If you are choosing to stay with Visual Studio, then which version and edition of Visual Studio are you using?

Hi Pete Letkeman,

I am using Android Studio 3.3. I am getting emulator error: 0xc0000005 which is discussed here
How to fix application error 0xc0000005

I am attaching a picture which would tell you the version. I am also attaching 2 pictures caught during running of application.I am not running visual studio along with android studio but I choose the emulator "visual studio android 23 arm ph

Hi,
Visual studio's version is VS2017

I'm using the same version of Android Studio, so I do not think that is the issue.

Here are a few things that you could try out:
- Create a simple "hello world" app using only Java code.
- Make sure that your environment variables are set up correctly as noted here https://stackoverflow.com/questions/16582107/android-studio-doesnt-start/28472229#28472229.
- Do not use Visual Studio's Android images, but use Android Studio's Android images.
- Update your Android SDKs, if  there is a update to be had that is.
- Try different Android versions like 5, 5.1, 6 etc to see if you get the same result.
- Some people have experienced issues with anti-virus software including Windows Defender. So try temporarily disabling them while running Android Studio.
- How about your system? Over all is it running as it should? Have you recently run a spyware and adware and virus check? This could be part of the problem.
- DANGER/WARNING: You could try the non stable channels of Android Studio, but this may cause problems as well.

Hi,
I was trying to execute the android application at the following link:
Install Android Studio and Run Hello World

After step 14, it shows a figure which does not match with mine. Is this a problem? What should i do?

Kindly guide me.

Zulfi.

Hi,
Number 3 component is not matching.

All is fine. In the example provided on the web the person selected the MainActivity class in Android Studio. In the picture provided by you, you have not.

Have you tried the HelloWorld app walk through provided by Google which can be found here https://developer.android.com/training/basics/firstapp/ ?

If you are looking for a learning resource you may be interested in know that Google provides a number of tutorials for Android developers for free along with the required source code found here https://developers.google.com/training/android/.

Were you able to get past the problem which you posted previously regarding Kotlin?
