No toolchains found in the NDK toolchains folder for ABI with prefix: mipsel-linux-android

This error comes due to NDK version mismatch, To resolve this error you have to download an older version of NDK and need to remap NDK path. Then you can build the project successfully. To do this please follow the below steps -

1. First, you need to open the NDK downloader page. You can open by using below URL -
https://developer.android.com/ndk/downloads/

2. Now at the bottom of this page, you can see "older versions of the NDK" and click on "NDK Archives" tag to see all older versions.

3. Agree with the Terms from this page by clicking on "I agree to the terms" button. After this, you can see all older versions of NDk.

4. Download your NDK older version from this list. In my case, it was "Android NDK, Revision 14b".

5. Open Android NDK location directory. You can check location from File -> Project Structure -> SDK location. Check below image for more information -

6. Now, Extract file which you have downloaded and move that folder in toolchains folder - (Or you can delete toolchain folder and past our recent downloaded toolchain on this location)

7. After this, you need to rebuild the project. 

This will resolve your issue. In some case, you can also try below solution -

Open Android Studio and go to File -> Project Structure -> SDK location, uncheck NDK If you do not need this, and then restart android studio. This will resolve your issue.

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)



I have found the solution for this error. The solution is very simple, You need to add the StoreKit framework. To add this follow below steps -


1. Clicking on your project in the upper left of the left pane and select project from TARGETS -

2. In the middle pane you can see the "Build Phases" section, Now click on the Build Phases tab.

3. After this under "Link Binary With Libraries", click on the plus button.

4. Now search for "StoreKit" and find the StoreKit from the list and press Add button.

Now run the project again and the project will get run successfully. This works for me if you are still facing any issue please post your error in the comment section. I will try to resolve this issue.

Note - In my case this issue I faced in ionic / Cordova projects. But this is a common issue related to Xcode.   

The sandbox is not in sync with the Podfile.lock in ionic

In my case, I was building an ionic project. This error comes when I try to run the project in iSO. I spend much time to resolve this issue, Some say we can run pod update OR pod install command to resolve this issue. But noting work in my case. Finally, I found the solution for this. This is very simple. Just follow the below steps to resolve the issue -    

1. First Quit your Xcode.
2. Now move in iOS platform folder. (i.e, Project Dir/platforms/ios)
3. Delete Pods folder from here.
4. Delete Podfile.lock from here.
5. Now open ios platform in the terminal and run "pod install" command in terminal. Make sure to run this command without admin (without sudo).
6. Now open your project in Xcode. Note - Open project via .xcworkspace file.

Now build and run the project, If that does not work follow below more steps - 

7. In Xcode, From navigation go to root node and from the Xcode on the right choose 'Build Settings' option.  Check more information in below image -

8. Now scroll down and there should be following entries - PODS_PODFILE_DIR_PATH and PODS_ROOT. If this available please correct the entry and if not available please add the entry by using below details - 


8.1 Click on the plus (+) icon to add the entry and select "Add user-defined settings". Check below image -

8.2 Add "PODS_PODFILE_DIR_PATH" and for both Debug and Release add "${SRCROOT}/." entry.
8.3 Now again add "PODS_ROOT" and for both Debug and Release add "${SRCROOT}/Pods" entry.

After adding the above details it will look like this -

Which Framework Is Better for Cross-Platform / Hybrid Mobile App Development? (Ionic Vs. React Native)

Ionic Vs. React Native : 

The objective of this post is to inform the most important differences between Ionic (2,3,4) and React Native, This artical will hopefully give you the information you need to make an educated choice about the stack that will work best for your project.

When you start to use new technology, you cannot be sure it will be the best solution. In some cases, some issues are through time duration and number of apps/projects. In this post, I am going to show a comparison between two frameworks, which are React Native and Ionic. I will explain based on my real time experience in app  development.
Now a days there are so many hybrid mobile frameworks are available, such as Ionic, NativeScript, React Native, Xamarin, PhoneGap. But according to me there are top 2 hybrid frameworks are available and which are — Ionic and React Native

Ionic Overview 

Ionic is an open source, cross-platform framework used to develop hybrid mobile applications. Ionic is a mobile app development framework based on the HTML5 programming language. The HTML5 framework always works with the help of Cordova or PhoneGap. Hence, Ionic needs both of them.

Ionic is the only mobile / hybrid app framework that easily allow web developers to build mobile apps for all major app stores and the mobile web with a single code base. And with Ionic’s Platform Continuity, your app looks and feels at home on every device. Ionic community has developed more than 4M ionic apps.

1. Ionic has free & Open Source — 100% source code on Github
2. Ionic is fully Cross-Platform  framework. Which can be used for IOS, Android,     Windows, Web, Desktop, PWA.
3. Ionic is premier Native Plugins — Camera, Bluetooth, Push Notifications
4. Ionic is first-class Documentation — Clear and Consistent

Advantages of the Ionic Framework

1. Fast development-testing cycle.
2. It cross-compiles to iOS and Android.
3. It is platform independent whether it has to work with HTML, CSS, JS, or AngularJS.
4. Ionic is easy to learn & work with.
5. In ionic you can write code in TypeScript (like angular 2,3,4 code), which makes it easy if you are having experience of AngularJS 2/3/4.
6. In ionic you can easily use TypeScript (like angular2) to develop applications for all platforms.
7. You can access the native functionalities of your user’s devices with the plugin system.
8. Angular itself is easier to learn & work with, for smaller projects than React.

React Native Overview

The goal of React Native framework is not to provide a way to write once, and run everywhere. Rather, React Native want all developers to use the components which is best for the native behaviors of the all platforms. For example, Android has a highly customizable toolbar but iOS does not have this. You can use the toolbar for Android but you need to use something different for iOS platform. 

React Native is a JavaScript library that is used to develop UI. React Native Framework is fully managed and maintained by a community of expert React Native developers and leading corporations, including Facebook and Instagram. It helps all mobile apps developers to reuse the code which is already used in any Android or iOS apps.

Advantages of React Native

1. React Native framework is developed by a very good and strong community of developers and corporations, which helps all developers to make speed up the learning and development process of there application.

2. React Native has response time that could be compared to native apps.
3. React Native has ability to reuse the code parts (not all code) for desktop (web apps) and mobile (mobile apps) and even for the server. 
4. React Native has quickly develop and debug the app functionality.
5. React Native has big amount of elaborated components from Facebook.
6. React Native has even bigger amount of components from community.
7. React Native allows developers to reuse existing code, it makes it very speedy to deliver the apps.


Ionic vs. React Native:

If you want to select development tool for your hybrid app from these two options, You need to definitely familiarize yourself with the all key features that makes Ionic and React Native different with each other.

However, I can just tell you which one I batter. It is React Native. I personally suggest the native rendering more than the other things. According to me, Apps speed need to be extremely fast, smooth and responsive, Also in React Native, I have found a good compromise between writing pure native code, or pure hybrid apps. This is the best part of rect native.

Now, According to me my best advise to you is : You should try them out both and pick one which is easy to use according to your requirements and make the best out of it!
