I recently migrated to Capacitor 3, and it appears that a few things have changed in terms of generated an APK with Ionic/Capacitor. Previously you were able to use the CLI to sign and build your release version of the APK, but now it appears that you need to use the Android Studio IDE to do so.
I am unable to figure out how to build my app within Android Studio.
It does not appear that I have any options available under my Build menu once the IDE launches after running the build command. I can see all of my files in the IDE, but I am unsure of what to do next.
Does anyone have any suggestions on where to begin when trying to use Android Studio for the first time for a production build?
Can you still use the previous CLI commands to sign your app?
Edit
Here is a screen shot of my Build menu from Android Studio:
SDK Platforms:
SDK Tools:
Go to Build -> Generate Signed Bundle/APK and follow the steps. You can provide the previous key that you used for signing. More info here
My Android studio OverviewFor some reason i cannot run any project with andoid studio on my andoid emulator, the buttons to quickly start the emulator and to run the project are greyed out.I updated android studio but everything is stil the same. Yesterday I was able to run any project, can somneone maybe told me what I maybe changed?
With the lack of problem info provided from you,I can only tell you of a probable fix
First make sure you have flutter sdk and dart sdk installed (if you don't know how check see https://flutter.dev/docs/get-started/install
Then after making sure you have these installed,
go to: file>project structure>modules>dependencies tab
And make sure that dart and flutter support check-boxes are checked.
Then go to main.dart and right-click and see if you have the option run main.dart available now.
I created my Flutter project by typing into my CLI Flutter create project_name and all this time I've been coding using VScode, and the project is near completion, which means I have to do a software demo in the coming days to my professors in university. However, I would need to open multiple android emulators that will run the same project, based on my brief research and testing, VScode does not allow running multiple android emulators that run the same project. So I have to transfer that project from VScode to Android Studio.
I've tried simply opening my Flutter folder in Android Studio and I'm getting gradle build errors. Any help would be appreciated thank you!
As long as you have the Flutter plugin installed in Android Studio, you can just open the folder like any other.
Though FWIW, I don't know if Android Studio supports debugging on multiple devices at the same time. It does work in VS Code (as shown at Flutter Interact with the "Flutter Octopus") if you're on the master channel (see https://github.com/flutter/flutter/wiki/Multi-device-debugging-in-VS-Code).
I downloaded Android Studio 3.1 and created a project. I did nothing in it and ran the project. Do I need to install any image?
Initial Screen - API version
Below screen comes when i click on run
I had Android version 2.2.2. I uninstalled it and installed version 3. After this, I was unable to download image for emulator.
I finally had to format the drive to get everything done again in first time.
you need to set your console to developer mode (i'm windows 10 user)
if you windows 10 user go to setting - update&security - for developers -
choose developer mode at use developer features
You need an emulator if you do not want to run your app directly in an physical android device. However, check if your PC supports or have libraries to run an emulator
NO, just check your PC config to run an emulator. Or you can download an emulator to run your app on Pc.There are many emulators with fewer config requirements.
You need the image to use simulator, besides, you may also need to change BIOS setting to enable virtualization if you are using Windows OS
I am developing an Android app using Android Studio (0.89 Build #AI-135.1404660, Built on Sept 3,2014) using both emulator and Nexus 4 device.
I had the same issue with a version prior to that.
The problem is that after I changed my code and resource files, I still get the old apk installed on the device or emulator.
What do I need to do to get it to run current code? Is it a building config?
Is it a known issue with Android Studio?
Or with a Nexus 4 device?
This is the second time it has happened, and I resolved it(then) after trying one of the steps below. They have not worked for me again.
Here is what I've tried
Build > Clean Project > Restart Android Studio > Run
Build > Rebuild Project > Run
Step 1 plus Uninstalling of apk on device
Step 2 plus Unistalling of apk on device
Adding erroneous resource entry then running.
I have read the following:
Android apk install: How to clear files from old version?
adb - How to reinstall an app, without retaining the data?
Device still has the old apk
Android build doesn't update code base or resources for target .apk on device
None has worked so far.
I had the same problem. After trying numerous methods that didn't work, I realized that I had accidentally changed an option in my "Run Configuration". Here's exactly what I did to fix the issue.
Run --> Edit Configurations
With your configuration selected on the left panel (mine says "app"), in the General tab on the right panel, there is a section called "Before launch". This section should have an option added called "Gradle-aware Make", but I had accidentally removed it.
I re-added it by pressing the "+", then clicking OK in the popup (leave the input box in the popup blank).
Click apply.
This fixed the problem immediately. Hope this helps someone!
Run / Debug Configurations / Miscellaneous TAB
[] Uncheck: Skip installation if APK has not changed
Android Studio doesn't always detect small changes in code.
The behaviour is erratic. I solved it by reviewing my code.It turned out that there was a resource file that was invalid. Try reverting back to the last working version of your code before the current changes... Probably a known issue that will be/was resolved out of Beta
Google thinks it is a feature, not a bug
https://code.google.com/p/android/issues/detail?id=156263
Their proposed solution is to copy the apk(s) instead of manipulating the filename, as in e.g.
Copying APK file in Android Gradle project
I've spent way too many hours to keep this to myself. The way I fixed it was that I noticed some hours later that I was using different layout version in res/ .... I have actually two versions of layout (layout-v26) and (layout). All this time I was modifying the other one and uploading different one. Maybe its just a newbie mistake but I hope somebody will find it useful.
The reason why there are 2 version was because of " autofillHints="" -> quickfix -> create new version of layout "

I am using android studio for building flutter app, I was facing the same issue untill I did the following:
From Android Studio, go to Tools-Flutter-FlutterClean
It resolved my problem as of now.
Check Your Layout Files.
I ran into the same problem and I realized, it gives some problem if you have same layout in multiple orientations(portrait and landscape). If one is changed other remains unchanged and then it creates a conflict. So android studio installs the one with the previous layout
PS: This was happening in my case.
The problem occurred on my Android 11 devices. I guess ART ran old code dex2oated.
Solution:
Run / Debug Configurations - General - Always install with package manager (disable deploy optimization on Android 11 and later), and check the option.
I was also facing this issue and get solution by deleting build folder manually because some time ide cannot be able to delete this. So go to the app folder and find build folder delete this and after clean and build project and run again.
projectname->app->build
You should select "Deploy default APK" option in Run/Debug Configurations. After that Android Studio will upload and install new apk to your emulator/device when you run application.
In android studio. at right side. see gradle option. click it. and then press circular arrows button shown in red square.
Same problem, none of the solutions mentioned here had any effect. I had to disable the "Allow parallel run" in "Menu > Run > Edit configurations...".
You can read more about this option here: How to run the same project multiple times in IntelliJ IDEA?
The solution to this issue is actually very simple.
Android studio is actually not detecting some small changes that you have made to the application. That is why it is installing the previous builds.
The solution is easy -> Remove the previous builds.
In the right side, go to gradle tab.
Expand Tasks. Find "clean" or "cleanCache" task or any task that starts with "clean". Double click to run that task.
Expand "app". and do the same.
Then File> Invalidate cache and restart.
Enjoy!! Your problem is solved...
My devices also ran old states - dont know from where in my git it has taken these.
I created a new configuration (default is "app") and it worked.
