Detailed Answer: Implementing responsive design in Android involves adapting your layouts to different screen sizes and orientations. Here's a breakdown of key strategies:
Use ConstraintLayout: This is the recommended layout manager. It allows you to define relationships between views, ensuring they adapt well to different screen sizes. Instead of relying on fixed dimensions (like dp for density-independent pixels), use constraints to position and size elements relative to each other or the parent layout. For instance, you can constrain a button to be centered horizontally and vertically, or have it maintain a specific aspect ratio regardless of screen size.
Utilize ConstraintLayout features: Explore features like Chains (for horizontally or vertically aligning elements and distributing space between them), Guidelines (vertical or horizontal guidelines to position views), and Barriers (to position views relative to the last view in a chain).
Employ different layout qualifiers: Android allows you to create alternative layouts for different screen sizes and orientations. You can create layout files named layout-sw600dp (for screens wider than 600dp), layout-land (for landscape orientation), or layout-port (for portrait orientation). Android will automatically choose the most appropriate layout based on the device's characteristics.
Use weight attributes in LinearLayouts (with caution): In LinearLayout, the layout_weight attribute allows you to distribute available space proportionally among child views. This can be useful for making elements expand to fill available space, but use this sparingly. In most cases ConstraintLayout offers a more flexible and efficient way to achieve similar effects.
Fragmentation for dynamic layouts: Use Fragments to create reusable UI components that can be dynamically added or removed based on the screen size. This is particularly useful for adapting your layout on larger screens where you might want to display more information or organize it in a different way.
Use wrap_content and match_parent strategically: While using ConstraintLayout, these dimensions can still be beneficial for certain elements. wrap_content makes the view only as large as its content, while match_parent makes it expand to fill the entire available space.
Test thoroughly: Test your app on various devices and screen sizes to identify any layout issues or areas that require further adjustment. Use Android Studio's layout preview and emulator to facilitate this process.
Simple Answer: Use ConstraintLayout, create different layout folders for different screen sizes (e.g., layout-sw600dp), and leverage layout_weight in LinearLayouts only when absolutely necessary. Remember to thoroughly test on different devices.
Casual Reddit Style: Yo dawg, responsive design on Android? ConstraintLayout is your homie. Make different layouts for different screen sizes (like layout-sw600dp for big boi screens) and use constraints to keep things looking tight, regardless of the screen. Fragmentation is also your friend for dynamic layouts. Don't forget to test it out on different phones before you ship it, or you'll get roasted!

Priority contacts in Android are a feature that allows you to designate specific contacts as having priority in receiving your calls and messages, even when your phone is in Do Not Disturb mode. When Do Not Disturb is enabled, calls and messages from non-priority contacts will be silenced. However, calls and messages from your designated priority contacts will still get through. You can choose to allow all calls from priority contacts or just calls from contacts in your starred contacts list. To use this feature, open your device's Settings app. Then, tap on Sound & vibration (or a similarly named option). Find and tap on Do Not Disturb. There should be a setting related to 'Priority only' or similar terminology. Enable this setting. Next, tap on 'Priority contacts' to customize your list of priority contacts. You can add contacts individually, choose to include all of your starred contacts, or add contacts from specific groups. Once you've set your priority contacts, calls and messages from them will bypass Do Not Disturb. Remember to adjust the settings within the Do Not Disturb menu to allow calls and messages from priority contacts to your liking; otherwise, they may still be blocked even if they're in the Priority Contacts list.
To summarize, Priority Contacts lets calls/texts from select contacts break through Do Not Disturb. Set it up in Settings > Sound & vibration > Do Not Disturb > Priority only. Add your chosen contacts there.
The Android Priority Contacts functionality elegantly addresses the need for selective notification filtering. By designating prioritized contacts, users effectively manage incoming communication, ensuring that critical calls and messages bypass the Do Not Disturb mode, while still enjoying the benefits of reduced distractions.
