Tips/help to debug no apk file - ibm-mobilefirst

My environment :
Eclipse sdk 3.7.2
Worklight pluin 5.0.5
Android sdk 2.2
First I tried a simple Hello World, everything works fine, android native project was created and I see the corresponding apk file was generated after a build and deploy.
Next I imported a sample project, successfully got it run on the test (localhost) server, able to see the expected result on the android Mobile Browser Simulator but the problem now is I am not seeing the corresponding android apk file got generated (the android native project was created). No errors on the logs, Any idea what could be the problem? How one debug such a problem.

APK will be generated under \bin\ folder once you run your app for the first time.
Connect your Android device to dev machine via USB cable (assuming you got Android SDK etc installed), right click on Android project and do Run as->Android app.
The app will be installed and started on Android device. APK will be generated in \bin folder.
In general, you don't need the device, same thing can be done with emulator.

You can also do an export on the android application project. This is what you would do if you are looking at doing some key signing. This is the way you would want to export it if you are uploading to Google play or an enterprise app store.
Keep in mind, Worklight doesn't build your .ipa, .apk, or etc. It builds you compile ready resources. It will build you the folder structure and the project layers needed to build in the corresponding Native Environment (for apple, you would export to xcode, build it, and run).

How to build .IPA file for testing in react-native?

I have build a project in react-native, for now I am testing the android app by using Expo Client App. I am using Visual Code in Ubuntu 18.04.
So the problem is, now I want to test the project for IOS, but unfortunately i can't test the app, because I don't have MAC OS.
Can anyone tell me the alternative solution of testing react-native project on IOS?
And if somehow there is a solution of creating IPA,then can I use that IPA in IOS without uploading it in AppStore?
You can use snack :
Snack lets you run complete react native project in a web browser,you can set it up on your local machine directly use it from snack.io which also let's you test for android and ios as well

compile apk on a folder "Android" already created previously in react-native

I'm new to react-native, I've seen tutorials but everyone uses expo. I downloaded this project where they don't use expo. I want to compile this application for android, to finally get an .apk
This application already has a folder called "Android" but inside it does not have its respective .apk. How can I generate it?
this is the repository:
https://github.com/zsajjad/BusinessCard
It would be great if you can attach screenshots of how I should do it
Note. I have the latest version of android studio and I don't see the option of "build"
commands like "gradlew" from the console, they don't work, it's as if I didn't have that command installed
Following instructions for build apk using android studio
Hope you installed node and react native on your machine. If not
please follow the link to install it.Install node and react native
open your command prompt or terminal and redirect to your download project - cd /Businesscard Master (change it according to your project location)
Now enter - npm install
Enter - react-native link
Follow the android related linking instructions on following link react native camera
Hope you know about android camera and storage permissions.
same thing for react native text detector. Because your downloaded project have that packages in package.json
Now open your project android folder in android studio using open existing android project.
Then select build your project from android studio build menu and run it also
Generate apk using build menu- same process you have to follow for native android project
You don't need to use the CLI, that's needlessly complicated and it obscures what Android Studio is actually doing. Here's all you need to do.
Open the whole /Android/ folder in Android Studio. This is your "project" similar to how you open a *.xed file in XCode. Except in Android Studio, you just open up the whole folder to get the build.
Android Studio will now prepare your project using Gradle. If there are any errors in the preparation it will tell you about them. Assuming your gradle and Android Studio versions are compatible and you got no errors, you're now ready to emulate, debug and create a production build. At this point the workflow is similar to using XCode. You'll see emulators under Tools -> AVD Manager.
In the file menus go to Build->Generate APK. You can choose between signed APKs, debug APKs and so on. You'll need the key file if you're signing the APK on your computer, otherwise there's also Google Play signing after you upload the APK.
TL;DR: Just open your /Android/ folder in Android Studio.
Side note: When Android Studio gives you popups to upgrade stuff don't do it. NEVER upgrade Gradle or Android Studio unless the RN / Expo team specifically ask you. This will break your whole project and you will need to rebuild the platform.

How to fix optimazition error publish in play store

my apk is 1.4MB but error is "This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users' devices than it needs to be. Larger apps see lower install success rates and take up storage on users' devices."
how to fix this error
It's only a warning, not an error.
For an app that small I wouldn't worry.
It's not something that's made its way into the Ionic ecosystem yet but I heard that if you open up your project in Android Studio and then do the build through there you can create an app bundle.
I'm not totally sure that its fully tested for Ionic so you might have issues with this, but Android have published a full guide:
https://developer.android.com/guide/app-bundle#get_started
This is what they say:
Download Android Studio 3.2 or higher—it's the easiest way
to add dynamic feature modules and build app bundles.
Add support for Dynamic Delivery
by including a base module, organizing code and resources for configuration
APKs, and, optionally, adding dynamic feature modules.
Build an Android App Bundle using Android Studio.
If you're not using the IDE, you can instead build an app bundle from the
command line.
Test your Android App Bundle by using it to generate APKs that
you deploy to a device.
Enroll into app signing by Google Play.
Otherwise, you can't upload your app bundle to the Play Console.
Publish your app bundle to Google Play.

Is it possible to compile a react-native app for android with an offline pc

Upon trying my first react-native android app with a win 10 pc, after entering the command react-native run-android, the compiler downloads a lot of files gradle-**-all and some *.pom files before finally deploying the app. i'm in a country with expensive data bundles so i want to ask:
Does this happen for every project, or every compile ?
If yes, are there workarounds ?
Because i need to be able to develop apps while offline.

How to test Phonegap application on Phonegap emulator

I am using Phonegap build to generate executable files for each platform. Each time I make changes in my code, I have to upload the code on phonegap build and generate new Apk file (for android). I don't want to test on real device, How can I test my code on phonegap emulator??
Getting started guides are very confusing for beginners like me. Please help me out.
You can download the AVD from http://developer.android.com/sdk/index.html. Click on DOWNLOAD FOR OTHER PLATFORMS and choose installer_r22.2.1-windows.exe if you are a windows user. Once you have installed it go to the install dir and execute SDK Manager.exe and download the virtual device images you need. Then execute AVD Manager.exe, create a virtual device and you are ready to go.
I Know I'm late but you can use this to test, then generate your apk when you're done.
Only for chrome
