Today I encountered the following error as I was building an Android app:
DataBinderMapperImpl.java:18: error: cannot find symbol
import net.catzie.myproject.databinding.ActivityMainBindingImpl;
^
symbol: class ActivityMainBindingImpl
location: package net.catzie.myproject.databindingTurns out, there’s an error in the related XML file, activity_main.xml! 😂
For other possible solutions, this StackOverflower answer may help: android: data binding error: cannot find symbol class
I’m starting a new category on my blog — Dev Diary, to document some of the errors that I encounter and what I did to fix them. I’m doing this in hopes of helping developers (including my future self!) as they work with code (and to get more blog visits! LOL). It’s nice to save time fixing a problem that you have already encountered and fixed before.
Today’s problem:
You are creating an instance of a class such as MoshiConverterFactory, but you get an error that says Cannot access '<init>': it is private in 'MoshiConverterFactory'
The solution:
Use the .create() method of the MoshiConverterFactory, like so:
.addConverterFactory(MoshiConverterFactory.create(moshi))
It’s been a long while since I last posted anything related to coding. I haven’t really stopped, but from Android app development, I switched back to PHP. Life has become occupied with other things, but when I do code, it’s in WordPress with WooCommerce. It’s for my online shop.
In my opinion, WordPress is not the most pleasant platform to use if you’re a developer (after years of MVC coding for Android I find WordPress quite messy), but it’s what I already know. I don’t have time to learn another.
Today’s code snippet is for customizing the Thank You page (post-checkout) by retrieving the “order” object.
|
1 2 3 4 5 6 7 8 |
<?php add_action(‘woocommerce_thankyou’, ‘thankyou_page_insert_order_details’, 11); function thankyou_page_insert_order_details($order_id) { $order = wc_get_order($order_id); echo ‘Thank you for ordering, ‘ . $order->get_billing_first_name() . ‘!’; } |
The $order_id is what we’ll start with. Then we get the order object with the help of the wc_get_order($order_id) method. Once you’re able to successfully call the order object, you may use its methods such as get_billing_first_name() to get the order details.
You may refer to the WC_Order class page for a list of available methods.
I originally got this code from Order Received (Thank you) page in WooCommerce and modified it to suit my needs. Check his blog out, as he has many helpful posts on how to customize WooCommerce!
I’ve been trying to push a new WordPress site’s codebase to my Bitbucket Git repository but it kept on failing with the following error messages:
Enumerating objects: 11966, done.
Counting objects: 100% (11966/11966), done.
Delta compression using up to 56 threads
fatal: unable to create thread: Resource temporarily unavailable
error: remote unpack failed: eof before pack header was fully read
error: failed to push some refs to '[email protected]:<my_workspace_name>/<my_repo_name>.git'I was trying to push my codebase from my server (hosted by Namecheap) to Bitbucket.
The solution to make the push work was to enter the following through command line on my server:
git config --global pack.windowMemory "100m"
git config --global pack.packSizeLimit "100m"
git config --global pack.threads "1"Reference: git push fatal: unable to create thread: Resource temporarily unavailable
Today I encountered a deprecation warning as I’m coding the app: 'getter for position int' is deprecated. deprecated in java
And I was like, whoa, this wasn’t deprecated a couple of months back when I last touched Android code… this is how long I’ve missed out! 😂😂😂 I haven’t touched any app code for a while, until this week. I am easing back into Android app development, and this time it’s for my personal use but hoping to share on Google Play Store for free… just in case it may help others.
The following RecyclerView Adapter code needs polishing 😂, but for the sake of showing you the deprecation warning, here’s a screenshot:
The deprecation warning is inside the ViewHolder class inside my RecyclerView Adapter file. By the way, I code in Kotlin now for Android apps.
I worked with a developer before who liked suppressing deprecation errors like this, but I advised him that it’s better to address the issue than suppress it because it will haunt him in the future! 🤣 I still believe in that up to now, so I searched for a solution.
This is the problematic line, and ‘position’ is the problematic variable:
|
1 |
viewHolder.textViewRecipeTitle.text = recipeNames.get(position) |
The solution? Simply replace position with adapterPosition.
And why is it deprecated? I found a note in RecyclerView.java:
* @deprecated This method is deprecated because its meaning is ambiguous due to the async
* handling of adapter updates. You should use {@link #getLayoutPosition()} or
* {@link #getAdapterPosition()} depending on your use case.
That’s all I have to say about the ‘getter for position int’ is deprecated. deprecated in java warning. Happy coding, you all.
I just began learning Kotlin for work and one of the first errors I encountered is “overrides nothing” pointing at the overrides of the function instantiateItem() for my PagerAdapter
The function/method signature was like this:
override fun instantiateItem(parent: ViewGroup?, position: Int): Any {
To fix the error, I simply removed the question mark from the arguments so that it looked like:
override fun instantiateItem(parent: ViewGroup, position: Int): Any {
Voila! Error gone and the swipe view that needed the PagerAdapter worked.
Reference: Sudden “overrides nothing” errors appear, no recent change to Kotlin build version
According to the Laravel docs, “After installing Laravel, you may need to configure some permissions. Directories within the storage and the bootstrap/cache directories should be writable by your web server or Laravel will not run”.
After running this command to install Laravel via Composer:
|
1 |
composer create–project —prefer–dist laravel/laravel blog |
Change directory ownership by running these commands:
|
1 2 |
sudo chown –R www–data:www–data /path/to/your/project/storage sudo chown –R www–data:www–data /path/to/your/project/bootstrap/cache |
Then you should see “Laravel 5” on your public folder when you visit it on a web browser.
Make sure you setup your app key by running php artisan key:generate, or else your Laravel still won’t run!
