Previously, I was doing some Google Play homework to update my app’s target SDK to at least Android SDK 35.

I thought I was done, but then Google sent me another violation email stating that my app now requires a 16 KB page size.

The deadline is November 1, 2025. I have a few weeks left, so here I am doing yet another annual Google Play homework.

Troubleshooting Flutter Android App to Target SDK 35 Upgrade

author@junian.dev (Junian Triajianto) — Tue, 30 Sep 2025 01:31:42 +0700

Another year, another chore: upgrading the Android app target SDK. This year, Google requires Target SDK 35.

So, here’s my experience upgrading an existing Flutter Android app. There were a few issues, but every problem has a solution.

Note: At the time of writing this tutorial, I was using Flutter v3.10.6.

Set Target SDK to 35

First, update the Android target SDK version manually by editing the android/local.properties file:

-flutter.compileSdkVersion=34
+flutter.compileSdkVersion=35
-flutter.targetSdkVersion=34
+flutter.targetSdkVersion=35
 flutter.minSdkVersion=21
 flutter.ndkVersion=26.1.10909125

After updating, build the Android bundle:

How to Use TP-Link Tether Without a TP-Link ID

I have a TP-Link router at home and usually use a web browser to access its configuration.

Lately, though, I’ve been too lazy to open my MacBook for this. So, I installed TP-Link Tether on my iPhone, planning to access it from my mobile.

To my surprise, it asked me to create an online TP-Link ID just to access my home router locally!

That’s unacceptable. I firmly believe you shouldn’t need an online vendor account to access hardware you own.

Removing Full-Screen Intent Permission from Flutter Android

Today I’m trying to submit a new version of the Flutter Android app to Google Play Store. I didn’t put any new features, just some bug fixes. I didn’t even change the dependencies. Normally no issue whatsoever when I send it to the Google Play Store.

But, something unexpected happened. I got an error message from the Play Store with the following message.

Your app uses the USE_FULL_SCREEN_INTENT permission. From May 31, 2024, some apps may no longer be eligible to have this permission pre-granted at install. Apps that aren’t eligible or approved for this, must request permission from the user to launch an activity with full-screen intent. If the permission isn’t granted and you don’t check for this, your app will crash when full-screen intent is being used.

Add a Password-protected SMB Share to VLC for Android

So I want to use VLC on Android to play some video from SMB Share.

But somehow it doesn’t work at all. The folder appears empty, and it doesn’t prompt me for a username and password.

The built-in Samsung My Files file manager app can access the SMB Share. That means something is wrong with the VLC Android app.

Not in the mood for reading? Watch the video instead.

So, I searched online and found out that you need to enter username:password (change it with your username and password) in the Username field.

Can't Start Android Emulator on macOS? It's Probably Conflicting with Docker

author@junian.dev (Junian Triajianto) — Mon, 05 Jun 2017 08:55:00 +0000

Weeks ago, when I was working on Android project, I noticed something unusual on my macOS machine. I couldn’t start my Android emulator. Every time I built the app, it just never showed up.

I rarely use real phone to test my app since Google now provides best Android emulator experience. So that’s why I always use Android emulator as first solution to test my app. So this kind of problem really made me down.
