 The best approach between <FrameLayout> and <androidx.fragment.app.FragmentContainerView> for showing fragments in Android development depends on your project requirements. Here's a detailed comparison: 1. FrameLayout (Older Approach) ✅ Pros: Works well for dynamically adding and replacing fragments. Simple to use and has been widely used in older Android versions. ❌ Cons: Doesn't provide built-in fragment animations. Might cause issues with fragment state restoration. Less optimized for modern fragment transactions. Example Using FrameLayout xml < FrameLayout android:id = "@+id/fragmentContainer" android:layout_width = "match_parent" android:layout_height = "match_parent" /> kotlin supportFragmentManager.beginTransaction() .replace(R.id.fragmentContainer, HomeFragment()) .commit() 2. FragmentContainerView (Recommended) ✅ Pros: Officially recommended by Android Jetpack for better fragment management. S...

Whether you’re a beginner or an experienced developer, this tutorial will help you streamline your Angular development workflow with Docker. Why Use Docker for Angular? 🔹 Eliminates “It works on my machine” issues 🔹 Simplifies setup with pre-configured environments 🔹 Ensures consistency across different operating systems 🔹 Eases deployment to cloud services 🔹 Makes CI/CD integration smoother Step 1: Install Docker Desktop To begin, you need Docker Desktop installed on your system. 🔹 Download Docker Desktop : Docker Hub 🔹 Choose the platform (Windows, macOS, or Linux) 🔹 Install and restart your system 🔹...

 Set Java: 1. Use Java 11 or 17 Instead of Java 18 SDK Manager works best with Java 11 or Java 17 . Java 18 is not officially supported for Android SDK tools. Run the following command to check your Java version: java -version sudo apt update sudo apt install openjdk-17-jdk export JAVA_HOME=$(/usr/libexec/java_home -v 17) export PATH= $JAVA_HOME /bin: $PATH Now, try running the sdkmanager command again. 2. Install android image using sdkmanager sdkmanager "system-images;android-34;google_apis;arm64-v8a" --sdk_root=/opt/android-sdk if sdkmanger is not found in emulator root@dee16e24c043:/# ${ANDROID_SDK_ROOT}/cmdline-tools/bin/sdkmanager --sdk_root=${ANDROID_SDK_ROOT} --licenses 3. Create emulator using avdmanager avdmanager create avd -n MyEmulator -k "system-images;android-34;google_apis_playstore;x86_64" --device "pixel_5" 4. Launch the Emulator root@dee16e24c043:/# emulator -avd MyEmulator -no-snapshot -noaudio -no-boot-anim 5. Install kvm if emulat...

 The difference between the two commands: apt-get install -qy <package> Uses apt-get , which is the older command-line tool for package management. The -q (quiet) flag reduces the output verbosity. The -y flag automatically answers "yes" to prompts. apt install -y <package> Uses apt , which is a newer and more user-friendly wrapper around apt-get . The -y flag automatically answers "yes" to prompts. apt provides more user-friendly output and progress bars compared to apt-get . Key Differences: apt-get vs. apt : apt-get is a lower-level tool, while apt is a more modern, interactive tool. -q flag in apt-get : This reduces output, whereas apt does not require it since apt already optimizes verbosity. When to Use Which? Use apt-get install -qy in scripts where minimal output is preferred. Use apt install -y for interactive use, as it provides a better user experience. For most modern usage, apt install -y is recommended unless you specifically n...
