I got below email from apple - 

Dear Developer,
We identified one or more issues with a recent delivery for your app, 
"-------". Please correct the following issues, then 
upload again.
ITMS-90338: Non-public API usage - The app references non-public 
selectors in ----: _setAlwaysRunsAtForegroundPriority:. If method names 
in your source code match the private Apple APIs listed above, altering 
your method names will help prevent this app from being flagged in 
future submissions. In addition, note that one or more of the above APIs 
may be located in a static library that was included with your app. If 
so, they must be removed. If you think this message was sent in error 
and that you have only used Apple-published APIs in accordance with the 
guidelines, send the app's Apple ID, along with detailed information 
about why you believe the above APIs were incorrectly flagged, to 
appreview@apple.com. For further information, visit the Technical 
Support Information at http://developer.apple.com/support/technical/

How to integrate wootric in ionic

Wootric integration with ionic 

There are two options to implement this -

Option 1 - Add below code after “build/main.js” Or add at the bottom of page.

<!-- start Wootric code -->
<script type="text/javascript" src="https://cdn.wootric.com/wootric-sdk.js"></script> 
<!-- end Wootric code -->


Now in your TS file (Where you want to trigger wootric survey) add below code -

/* Wootric code start */
 window['wootric_survey_immediately'] = true; // Comment out the line wootric_survey_immediately = true when you are ready for production. Alternatively, leave the line in the code for testing purposes or to survey the customer upon every visit to a specific page.
 window['wootricSettings'] = {
   email: (user.email)?user.email:'',
   created_at: Math.floor(Date.now() / 1000),
   account_token: "NPS-********”, // You need to update your account token here
   otherData: {
     city: user.city,
     role: user.role
   }
 };
// console.log('wootricSettings:', window['wootricSettings']);
//console.log('WootricSurvey');
window['WootricSurvey'].run("wootricSettings");
/* Wootric code end */


This will trigger wootric survey on the selected page.
Note - You need to update account token on “NPS-XXXXXXXX”

Here - user.email is user email id, otherData are additional data which you want to send on wootric.




Option 2 - You can also integrate into the ionic framework with the help of javascript code. To integrate this you just need to follow below steps -

Insert below javascript code in the bottom of your index.html file 

<!-- start Wootric code -->
<script type="text/javascript">
  window.wootric_survey_immediately = true; // Shows survey immediately for testing purposes. TODO: Comment out for production.
  window.wootricSettings = {
    email: 'customerEmail@example.com', // TODO: Required to uniquely identify a user. Email is recommended but this can be any unique identifier.
    //external_id: '123abc', // TODO: Reference field for external integrations only. Send it along with email. OPTIONAL
    created_at: 1234567890, // TODO: Date as a 10 digit Unix timestamp in seconds. OPTIONAL
    account_token: 'NPS-XXXXXXXX' // This is your unique account token.
  };
</script>
<script type="text/javascript" src="https://cdn.wootric.com/wootric-sdk.js"></script>
<script type="text/javascript">
  // This loads the Wootric survey
  window.wootric('run');
</script>
<!-- end Wootric code -->


This will trigger wootric survey when your all launch.

App not setup this app is still in development mode and you don't have access to it

To integrate Facebook with your app you need to create app inside of Facebook developer portal. You can create by using below URL -

https://developers.facebook.com/apps

Here you will see add a new app option -

Now after creating the app, you will get App ID and App Name from Facebook. This you need to integrate FB in your app.

Now please follow the below steps to integrate FB -

STEP 1: Go to the “Settings” tab and select the “Basic” option. Now add your contact Email.

STEP 2: After step 1 please select “Facebook Login” tab then select “Settings” option from here. Now from top right section enable “Status”. So that your app will be live.

If you got this error - You must provide a valid Privacy Policy URL in order take your app Live. So you need to move in the "Basic Settings" section and make sure all details are valid.

Now, You need to add a Privacy policy URL in the basic setting tab. (Settings -> Basic ->Privacy Policy URL)


After adding this again enable “Status” from the top right corner. Now your app will be available for live users.


Note - If you are in development mode then you can check functionality by using your own FB login details by which you have created FB app. This account doesn't need to make the app live.

The best way to test the app is to create test users of the app. You can create from "Roles" then "users" from the side menu section.

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.


Please post a comment if you are still having an issue in this. I will try to resolve that issue.
