Android Studio Emulator Stops my App from Showing - android-studio

I tried running my emulator and it gave me a message saying that my app failed to work. I then looked in the LogChat in Android Studio and found these error messages. I am new to android studio and I'm not sure what to do to make this app work on the emulator and get rid of these errors.
I have tried to run the emulator from Android Studio and this is the error

Normally, these errors don't show up

Ok, now that the repo is in place, this is really easy to fix, just go to your viewPagerAdapter, and change the null in the getItem method:
And then.....magic!
You are returning a null fragment from your adapter, that's all

From the logs, it is clear that your code is trying to operate on null object and throws NullPointerException in BackStackRecord.java at line 396. Check that line and give your variable default value "0" or whatever that does not affect your result. Try running the code. It should work. Or Please provide the snippet of the code for review.

Version of dependency not found

I have an Android App that is published in Google Play.
I tried to publish a new version and the Google Play console asked me to update the sdkVersion to 30, it was 29.
I modifyied to 30, and Android Studio warned me that I should update to 32 the sdkVersion. So I changed: compileSdkVersion and targetSdkVersion to 32.
Then Android Studio warned me about new version of dependencies, so I updated all to the latest version sugested.
Now, trying to run the emulator of Pixel 3a API 30 I get:

Why I get warned about not finding the version 17 when I configured the API version as 20.0.0?
This is only because I have to change something the emulator configuration?
Since the app was working fine in the emulator before this changes, and the installer I created works fine on my Android 12 smartphone, it is safe to create a bundle and publish in Google Play?

The command that fails is
return EncryptedSharedPreferences.create(

context,
EncryptedSharedPreferences.PrefKeyEncryptionScheme.AES256_SIV,

Is that mean I should use a different schema? What about current sharedPreferences file that is in use? It will fail because of that, no? Any idea what can be done? Thanks
This version of the library fixes the problem that was caused by the previous RC version. I can't remember exactly what it was, but it was something to do with the tinc library and dependancy clash with other libraries like Firebase.
To fix the previous issue I had to add the following to my build.gradle:
allprojects {
configurations.all {
resolutionStrategy {
force("com.google.crypto.tink:tink-android:1.3.0-rc1")
}
}
}
Removing it again fixed the same crash as you had here.

While there are no errors in the build, installation & syncing process, I don't understand how to troubleshoot further.
Try to follow those steps (Android/iOS):
Remove node_modules using this command :- Android:- rm node_modules Or
iOS:- rm -rf node_moduels
Remove hooks using this command:- rm hooks / rm -rf hooks
Remove platforms using this command:- rm platforms / rm -rf platforms
Or
tns platform remove android/ios.
Again Install the npm using:- npm install.
Add the platform in your project:- tns platform add android/ios
Again run your project:- tns run android/ios --bundle

Android Studio 3.2.1 - Cannot sync project with gradle files: Argument for #NotNull parameter 'message' of ... must not be null

I have a problem using AndroidStudio. I freshly installed it on my Kubuntu 18.04 machine and wanted to create my frist project. Everyhting worked fine and the project opened. The only problem: I can't run my apps. I can't even look at the activities in the design view - It waits forever for the build to finish. When I want to run the apps, it doesn't have any modules.
After searching for a while on the web I tried syncing my project with the gradle files, because that seems to resolve similar issues, but once I do that, the following error occurs:
Argument for #NotNull parameter 'message' of com/android/tools/idea/gradle/project/sync/GradleSyncState.syncFailed must not be null

After doing it once, the button for syncing is disabled and I can't do it again. I have to restart the IDE to do that.
I looked into the idea.log file to better track down the issue and I found the following there:

It seems like the project can't be synced to my gradle files. Probably the actual problem of running my app is based upon this one. Has anyone had this issue before or can help me by telling me how to tackle this?
I am completely new to AndroidStudio and also to Gradle.
Ok, I was finally able to figure out the reason.
The problem was, that my project folder resided on a different hard disk partition, than my home folder. The folder containing my android projects was linked to my home folder with a symbolic link.
I can't tell whether its the symbolic link, or the other partition, that is causing the problem. I haven't checked that. Maybe it works if you have it on the same partition but linked with a symbolic link. Maybe it works when used on another partition without symbolic links. But for anyone experiencing this problem -> Check if one of these might be your cause as well.
Some extra information: My android project folder resided on a hard disk partition formatted with ZFS.
I saw a version of this with just now on Android Studio 3.4: the only error message I saw in the IDE was that Gradle sync failed, but in idea.log there was a NullPointerException and its traceback originated at com.intellij.openapi.extensions.Extensions.disposeArea and was just like the one in the question.
The fix that worked for me:
rm .idea/modules.xml
Then try Gradle sync again.
This also caused that file to get automatically regenerated. The new version had exactly the same entries as the old, plus some additional ones for various library dependencies. Not sure if those entries being absent was the cause of the issue, or an unrelated accident.
Before that, I tried "Invalidate Caches / Restart...", and it didn't work in my case. Also double-checked and there are no symbolic links in my project path, or the paths to Android Studio or the Android SDK.
Had a similar problem after renaming the project folder and adding the renamed folder as new project.
solved this by the infamous "Invalidate Caches / Restart" option
(before I removed the old project link which was not enough)
check this :
Argument for #NotNull parameter 'module' of com/intellij/openapi/roots/ModuleRootManager.getInstance must not be null
by the way , i usually delete .idea and .gradle folders inside my project folder after updating android studio , almost works for all new bugs after updating .
Faced same issue, wasted a day reinstalling everything and figured out just now. It happens if you create a symbolic link to your project and specify the path through that symbolic link. Just specify the project path by going the long way and everything will work just fine.
I had the same problem. I move the ~/Android/Sdk folder to a different partition and placed a symbolic link!!!
Solution for me:
Delete .android , .AndroidStudio3.2 , .gradle folders
Start studio.sh again and let it initialize things as for the first time. Then go to File->settings->System Settings->Android SDK and give the new location to the Android SDK folder as an absolute path (not symbolic links).
After this, it worked like charm.
I solved the problem by rename the project folder and then reopen android studio , android studio will tell you that it can not find the project , then remove the project from the android studio current open list . rename project folder back and open it by android studio again .
I got same issue in Android Studio 3.4.
I managed to fix it by restoring my previously deleted app-name.iml file.
I also had the same problem and simply resolved it by closing android studio, deleting .idea and .gradle files located on the project folder and then reopening android studio.

My app is crashing whenever I am trying to open the app info in settings tab. It also looks like referring to the old package name

This is happening after I changed the package name. The app crashes only when I open "About"
This is the crash report

Try adding android:exported="true" to your AndroidManifest.xml where your Activity is declared.
Also, double check that you are launching the correct configuration.
