What is android

          The name “ANDROID” hits the market only after four years of its development. Before 2007 the majority of mobile phone users are deficient. Even if they are using, they are not smartphones. There were only two operating systems that are available. They were Symbian for the Nokia phones and the Blackberry OS for Blackberry phones. These operating system has notable flaws and is not comfortable to use, to overcome this in November 2007, Google released its first version of android and in September 2008 the first android phone named “T-mobile G1” with Android 1.0, 3.2-inch touchscreen and physical QWERTY keyboard.

Is Google who developed android? No, Android Inc. It was founded in Palo Alto, California. It’s four founders were Rich Miner, Chris White, Nick Sears, Andy Rubin. Their ultimate aim of android is to develop a smartphone that is more aware of its “Owners location and Preferences,” and later 2005, the company was only sold to Google.

Android studio

          Android studio is a suitable integrated development environment (IDE), which built on JetBrain’s IntelliJ IDER software, the software developing company located in Prague 4, Prague, Czechia. This tool is designed for improving the stability of android. This software supported in all the operating systems such as Windows, macOS, and Linux. The Android studio tool is the replacement of the previously used tool named Eclipse Android Development tool (ADT), and now Android studio is the primary tool for android development till now. Google officially announced an android studio on May 16, 2013, in the Google I/O conference. Then they release the first beta version of 0.8 in June 2014. As of its importance and specification, the stable version released in December 2014 with the text of 1.0. Till now, they released a total of 17 versions of Android studio. The last version was 3.6, which released in February 2020.

Languages used in android studio

          Android Studio uses “KOTLIN” as the official language in early 2019. But on May 7, 2019, the official language of Android studio was changed to “JAVA.”

  • JAVA—It’s the official language of Android studio because most of the android application that is available in the play store developed using the language called JAVA. Because its the word designed for application development. Java code runs employing Virtual Machine on Android devices, and they then interrupt the system given.
  • KOTLIN—It’s the “second” official language used in the Android studio because it also runs in the same java virtual machine, and it is the language that is being used for the beginners, as they are easy to learn. They can be easily understandable by the starters.
  • C/C++–The language that is not widely used by everyone. The primary use of this language is for the development of the “Gaming application” because they do not run in java. Virtual memory uses separate memory; besides this, they are hard to use because they produce more debugs and less flexible.
  • BASIC—Easier language than any other because it has very few options for developing an android application called B4A IDE. It is the dominant language and easy one.
  • Phone Gap— The one who has more knowledge in web development (HTML, CSS, JAVA SCRIPT) can use this language for cross-application.

Solution to solve problem

  • The solution for this problem is very simple they can be solved by the only way to check each and every XML file and point out where the exact error is and then change the coding in the XML file. Obviously, this is time-consuming, but this is the way. But if you are using the updated version of the android studio, then it will make your work a little easier, because it will point out the exact line that has the error. So, we can make the change easily.
  • The above problem picture can be solved by searching and replacing com.android.support:support-v4:+ with com.android.support:support-v4:27.1.0 in the platform/android directory.
  • If we use the same line twice, then the solution is very simple, remove the duplicate line, and then the error disappears.
  • For windows, if we are using the windows 10 and the android studio version 3.2, then simply go to the application and select the build.gradle and then change the version
  • As I mentioned the error: com.android.builder.internal.aapt.v2.aapt2execption can be solved, if you are using the key tool command line to produce a signed apk, then you just change it to the android studio it will work.
  • Another method is that to force the Gradle to build all the needs with two versions of the main project, they are SDK and tools version, then the line android/build.gradle  be added with SDK needs.

points to find error in a quick way

  • It is the second way to find the error easily if the error occurs then open every XML file by doing, so the android studio itself underlines the mistake done.
