Android is an open source mobile platform launched by Google in 2008 and ever-since it became the favourite for people and developers around the world. Android is Linux based multiprocess and multithreaded OS. Google's Android OS is not limited to phones but you can use it to build a DVR, a handheld GPS, an MP3 player etc.
Although Android platform is an open source and customizable, Android users and developers have become habitual to the constructs developed by Google for Android devices. The use of these Android concepts is vital for developing an application quickly.
Apps and APK Files An Android app is an Android Application. An app is packaged in an APK file i.e. Android application package. The apk clash royale unlimited gems file contains the compiled Java code and other resources like images and texts for the Android application Activities An Android activity is a GUI component. You can understand it as a window in a desktop application. As mobile phone screens are small, an activity takes up the whole screen. If you open multiple activities then they are stacked on top of each other. You cannot arrange activities side by side like you can do with desktop windows. Activities are unique, focused actions which a user can take. As it is difficult to scroll, zoom in or click links on a small screen hence it is recommended that an app display only one activity per screen. This will present the most relevant information to the user and allows them to launch a new screen for additional information or click the back button to view the previous activity. The screen can expose multiple tasks but it should help the user complete just one activity at a time. Fragments In Android, a fragment is a fragment of a total user interface. A fragment only takes up part of the screen. Fragments are used in the activities. Fragments can also be used within different activities. Fragments contain Views and ViewGroups inside them. View and ViewGroups Android GUI elements come into three categories i.e. Activities, Views and ViewGroups. Activities are the windows/screens. Views are the individual GUI elements, like a TextView which displays a text, a Button that users can click on etc. ViewGroups are containers for Views. A ViewGroup actually groups a collection of Views together. Views and ViewGroups can be nested inside an activity or inside even a fragment which is nested inside an activity. Layout XML Files Activities, fragments and ViewGroups can use XML files to define their layout and contents. The layout XML files tell which GUI components an activity or fragment contains and also the styling of the GUI components i.e. The size, margins, padding etc. Intent If your app requires performing a function beyond its core capabilities like opening a photo, playing a video or looking up a contact then you should find out whether a tool that can perform that function already exists in the OS or in a third-party app. If yes then you can get the benefit of that functionality using intents. For e.g. If your app accesses user contacts then you can use intent objects to launch the device's existing Contacts application. This removes the programming duplication and also speed up the user's interaction with the device as the user will not need to learn again how to add a contact to your app. Widgets Android Widgets are actually GUI components which can be displayed outside of an activity. For e.g. A weather widget which shows today's weather is shown on many Android home screens. Widgets have been packaged and implemented as part of an Android application. Also sometimes Views in Android are also referred to as widgets. For e.g. Many GUI components are placed in a Java package called android.widget. GUI components are not same as a widget which can remain on the home screen of an Android device. Hence you should understand the difference between GUI components which can be used inside ViewGroups, Fragments and components which can be used inside ViewGroups, Fragments and Activities and also inside Widgets and Widgets which can remain on the home screen of the Android device. Services In Android, Services are background process which can be executed on an Android device even if no application is visible. Services do not require a user interface. For e.g. A Service can check a remote server for updates or backup data every hour. Sensors Android devices have many inbuilt sensors which you can access from your Android applications. For e.g the inbuilt GPS in smartphones is a sensor. Therefore you can get access to the GPS from inside your Android applications.

The 2022 World Cup in Qatar in November/December means a six-week pause to the domestic campaign in a historical first for English football.
The timetable for 2022/23 has been based around the season going on hiatus from November 12/ Germaine Pratt Jersey 13 until December 26, with a major overhaul to the traditional schedule.
However, before focus turns to Qatar later this year, all eyes will be on the Premier League, and The Sporting News takes a look at who has the easiest schedule in 2022/23.

Who has the easiest start to the Premier League 2022/23 season?
Based on the 2021/22 season, there will be very little margin for error right from the off in 2022/23, with the arrivals of Erling Haaland and Darwin Nunez showing title rivals Manchester City and Liverpool already mean busine s.
The inclusion of the World Cup will not change the demands of a gruelling 38-game campaign and teams will be aiming to head into the mid-season break in strong form.
In terms of the title race, Jurgen Klopp's Liverpool face Manchester United on August 20, followed by a Merseyside derby at Everton on September 3, but City have a real chance to march ahead at the top.
Pep Guardiola's defending champions do not face any team who finished inside the top six last season until Matchday 7, when they host Tottenham on September 10.

The newly promoted sides have a mixed picture as they kick off a return to the Premier League with Forest, Fulham and Bournemouth facing a tough road ahead.
Fulham and Bournemouth face three of last season's top six before the end of September, but the fixture computer has been kinder to Forest in the opening weeks.

Who has the easiest Premier League 2022/23 fixtures after the World Cup?
The challenge of factoring a World Cup into the Premier League calendar is set to dominate the conversation in the coming months.
The 2022/23 season restarts for the traditional Boxing Day (December 26) games, with the Premier League removing the game week in between Christmas and New Year, to reduce the demands on players.
The rearranged post-World Cup schedule means five Premier League games per club crammed in from December 26 to the end of January.
With players potentially returning to their clubs at different stages, based on how succe sful their national sides are in Qatar, the start of 2023 will be a balancing act acro s the board.
City's potentially welcome start is not replicated after the World Cup, with roles reversed between themselves and Liverpool.
Guardiola's team face Chelsea and Manchester United in January (2nd/14th), either side of an FA Cup weekend, with Klopp's Reds only taking on Chelsea (Jan. 21) from the 2021/22 top six in their nine games after the restart.

As the Premier League title race, top-four battle and the relegation fight all went down to the wire in 2021/22, the end of season run-in will again be crucial.
Teams at both ends of the table will be a se sing which matches could decide their fate in 2023.
If, as expected, City and Liverpool are locked in a title war, City's home game against Chelsea on the penultimate weekend (May 20) could be the decider.
Guardiola' Giovani Bernard Jersey s team face a tricky final month of the season, either side of facing Chelsea, with a home tie against rivals Leeds United, plus trips to Everton and Brentford.Liverpool will be looking to benefit from that, as they take on Brentford, Leicester City, Aston Villa and Southampton who all ended 2021/22 in mid-table in their own run-in.
