It’s funny how we spent about an hour trying to figure out why the Intent extras that we’re setting are not being sent back to onActivityResult(). If we only knew that the solution was as simple as moving one line of code. The call to super.onBackPressed() should be placed after setting Intent extras and after […]

Android app dev: Missing import org.apache.commons.lang3.text.WordUtils;
I use a few instances of WordUtils.capitalizeFully() on an Android app that I’ve been working on. And there are times when the import org.apache.commons.lang3.text.WordUtils; breaks, sometimes after merging with some of my git branches. To fix this, what I do is open app/build.gradle and add the following line under dependencies:

Android RecyclerView notifyItemChanged() IllegalStateException “Cannot call this method while RecyclerView is computing a layout or scrolling”
If your Android app is crashing with error IllegalStateException “Cannot call this method while RecyclerView is computing a layout or scrolling”, you may try placing your notifyitemchanged inside a Runnable.

|
1 2 3 4 5 6 7 8 9 |
myRecyclerView.post(new Runnable() { @Override public void run() { myArrayList.remove(position); myArrayList.add(something); recyclerViewMainScreenHeader.getAdapter().<code>notifyItemChanged</code>(); } }); |

Manila homemade cakes, cupcakes, cookies, brownies & more desserts at The Tiny Cakery
Update: We have rebranded into Catzie’s Cakery. When I’m not busy tapping codes on my keyboard, I either watch anime or bake. And there’s this “tiny” baking business in Manila I’m running, and really have a good time baking for people – friends, family, and even people I haven’t met prior to handing over their […]
Simple SMS Reader app in Android using BroadcastReceiver class
Before I began coding Android apps, I was amazed how verification processes go like this: The Android app tells you they’ll send you an SMS containing verification code, and that you need to enter such code into a text field on the Android app. But when you receive the SMS, the verification code appears on […]
