Which is best or in android development?

 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...

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.

what is the difference of "apt-get install -qy" and "apt install -y"

 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...
