Fixing a Missing TextView Issue in Android Studio (Layout Shows Title but Not Subtitle)

While working on an Android app UI, I encountered an issue where a TextView subtitle refused to appear on the screen, even though:

  • The layout XML was correct
  • The app compiled successfully
  • No runtime crashes occurred

Interestingly, the main title showed up perfectly — only the subtitle was missing.

Initial Setup

The layout used a simple LinearLayout with two TextViews:

<TextView
    android:text="@string/title_home" />

<TextView
    android:text="@string/subtitle_home" />

The subtitle text was defined inside strings.xml and referenced correctly.

Root Cause

The problem was not the layout and not the string resource.

The real issue was caused by:

  • Android caching old resources
  • The app process still running in memory
  • The emulator reusing a previous app state

In short: the UI was not refreshing with the updated resources.

The Fix (What Finally Worked)

To force Android to reload everything correctly:

  1. Terminate the running app process
  2. In Android Studio: Build → Clean Project
  3. Then: Build → Rebuild Project
  4. Cold boot the emulator
  5. Run the app again

After this, the missing subtitle appeared as expected.

Verification

Once the subtitle became visible, it confirmed that:

  • The correct layout was loaded
  • The updated strings.xml was being used
  • Caching issues were fully resolved

Key Takeaway

If a UI element does not appear in Android but:

  • No errors are shown
  • The XML is valid
  • The app runs normally

Always suspect caching first. A clean rebuild and full app restart can save hours of debugging.

From DSRC to 5G NR-V2X: The Road Ahead for Connected Vehicles

Modern vehicles are no longer just machines on wheels. Through Vehicle-to-Everything (V2X) communication , they are becoming active participants in intelligent transport systems, enabling safer driving, smoother traffic, and progress toward automation. DSRC: The First Step The earliest V2X technology was Dedicated Short-Range Communications (DSRC) , based on IEEE 802.11p. Operating in the 5.9 GHz band , it allowed onboard units (OBUs) in vehicles to exchange safety and infotainment data with roadside units (RSUs) . While DSRC was effective for short-range messaging, it faced limits in coverage, data rate, and quality of service (QoS) . These challenges motivated researchers to explore new solutions. D2D and the Cellular Shift A key breakthrough came with Device-to-Device (D2D) communication , where vehicles exchange information directly without always relying on infrastructure. This reduces latency, eases network congestion, and helps maintain reliability in crow...

🔹 Is Qualitative Data Always Primary Data?

🔹 Is Qualitative Data Always Primary Data? Insights from Stroke Care and IoV Research Understanding stroke care isn’t just about what happens — it’s about why it matters . In our recent research, we use a mix of sensor data , patient feedback , and AI-driven IoV analytics to capture the full story ( Saad, Jamshed, Adedamola, Nauman, & Kim, 2025 ). 📄 Click here to view the full paper 🧠 Primary vs. Secondary Data Primary data → Data you collect yourself (interviews, observations, or IoV sensor readings). Secondary data → Data collected by someone else (published reports, case studies, open datasets). For example, if we interview stroke patients or observe IoV interactions , that’s primary qualitative data . But if we analyze existing case reports or published interviews , that’s secondary . “The last decade has witnessed considerable growth in the development of qualitative research... yet this is an area on which most researchers require some guid...
