The main reason being that it is this operating system is based on linux build with open source software. In addition it uses Java for android development, which is quite an easy language to get used to and develop in. Specially for the expert java programmers , you have a step to become a best of android developer.
For the beginner of android apps developers , you can start step by step to become a advance in the Android Applications Development. Windows 8 or bit , Windows 8. On Ubuntu Linux, version For information about how to add support for bit applications, see the Ubuntu Linux installation notes. Several types of Eclipse packages are available for each platform. For developing Android applications, we recommend that you install one of these packages:.
During the creation of his account, his location and picture will be monitored. Voter can cast vote remotely from anywhere in the country with the help of an android device and voting application on his device.
I have used Aadhar Number and Voter ID for unique identification of users, and they can register using these details in This Android App shows the total Covid cases recorded all over the world.
Also updates the latest figures of Covid cases. With Android Drawable Preview Plugin, you do. This Android Studio plugin replaces the default icons with drawables previews inside the project view. Super-easy to access, but not an excuse to use ambiguous names for the drawable assets. Keep it descriptive, always. Let me start by busting a myth. Not all women can tell the difference between turquoise and teal, or eggplant and plum.
The very much female writer of these lines is one such example. And I am not even color-blind. The Name That Color plugin will name the color you have in your clipboard directly inside your color resource file in Android Studio, and give the name of the closest matching color.
This tool by Google is a must-have for more efficient APK packages. It generally improves code readability, letting you to focus on the logic rather than glue code for finding views or adding listeners.
Developing with ButterKnife allows you to perform injection on arbitrary objects, which can get pretty complicated and tedious once you need to perform more than one or two. At this point, you need to refer to all layout XMLs to write them in the source file. Or you can simply install ButterKnife Zelezny. See the new interfaces in the com. As part of the new Variant API, we have made available a number of intermediate files, called artifacts, through the Artifacts interface. These artifacts, like the merged manifest, can be safely obtained and customized by using third-party plugins and code.
We will continue extending the Variant API by adding new functionalities and augmenting the number of intermediate artifacts we make available for customization. For Android projects consisting of an app with library dependencies, it is recommended to set checkDependencies to true as shown below, and to run lint via.
If a module's sources and resources have not changed, the lint analysis task for the module does not need to run again. As a result, Lint can run even faster. The Lint report task also does not need to run if its inputs have not changed. AGP no longer supports running lint from dynamic-feature modules. In previous versions of AGP, it would run lint for all variants. R8 more precisely and consistently handles missing classes and the -dontwarn option.
Therefore, you should start to evaluate the missing class warnings emitted by R8. When R8 encounters a class reference that is not defined in your app or one of its dependencies, it will emit a warning that appears in your build output. For example:. This warning means that the class definition java.
Two common reasons to ignore the warning are:. You can ignore a missing class warning by adding a -dontwarn rule to your proguard-rules. Add the rules to your proguard-rules.
In AGP 7. In AGP 8. It is possible to keep the AGP 7. Previously introduced in AGP 2. This change does not impact build time. To enable this feature, set compileOptions to the desired Java version and set compileSdkVersion to 30 or above:. In most cases, the AGP Upgrade Assistant will automatically migrate your project to the new configurations. If you are compiling against the Android Gradle plugin, your compile classpath may change. If you depend on an AGP dependency at compile-time, be sure to add it as an explicit dependency.
Previously, you could add a native library in a Java resources folder, and register the folder using android. Starting with AGP 7. Instead, use the DSL method intended for native libraries, android. For more information, see how to configure source sets. Android Gradle Plugin 7. Projects that use the Kotlin Multiplatform support need to update to Kotlin 1. As a workaround, you can downgrade the Android Gradle plugin to 4. For more information, see KT There is no lint text output printed to stdout when the lint task is up-to-date issue For more context, see Behavior changes for lint.
This issue will be fixed in Android Gradle plugin 7. As a workaround, the lint task can be run on those libraries. Starting in version 4. Java 8 provides access to a number of newer language features including lambda expressions, method references, and static interface methods. For the full list of supported features see the Java 8 documentation. To keep the old behavior, specify Java 7 explicitly in your module-level build.
The new JVM resource compiler is enabled by default. Android Gradle Plugin 4. To enable one or both of these formats in your build, add the following properties to your module-level build. This new flag takes care of the APK signing step in the deployment process. It is now possible to enable or disable app signing in Android Gradle plugin per variant.
This example demonstrates how to set app signing per variant using the onVariants method in either Kotlin or Groovy:. To reduce clutter in build output, AGP 4. Previously, a line of output was generated for every file that was built, resulting in a large quantity of informational messages.
If you would like to see the entirety of the native output, set the new Gradle property android. You can set this property in either the gradle. Command line -Pandroid. Starting in AGP 4. In other words, if you declare a property in a gradle. In AGP 4. This change reflects the new Gradle behavior and supports configuration caching. For more information on setting values in gradle.
In previous releases, JDK 8 was bundled with Studio. When using the new bundled JDK to run Gradle, this may result in some incompatibility or impact JVM performance due to changes to the garbage collector. These issues are described below.
Android Studio 4. For more information about Gradle compatibility, see Update Gradle. To potentially improve build performance, we recommend testing your Gradle builds with the parallel garbage collector.
In gradle. To measure build speed with different configurations, see Profile your build. This causes an increase in APK size, but it results in a smaller installation size on the device, and the download size is roughly the same.
This means that:. This means that it is no longer possible to write the following in Kotlin scripts for some collections that previously supported it:. Android Gradle plugin 4. To export your native libraries, add the following to the android block of your library project's build.
In this example, the mylibrary and myotherlibrary libraries from either your ndk-build or CMake external native build will be packaged in the AAR produced by your build, and each will export the headers from the specified directory to their dependents.
Kotlin uses custom metadata in Java class files to identify Kotlin language constructs. R8 now has support for maintaining and rewriting Kotlin metadata to fully support shrinking of Kotlin libraries and applications using kotlin-reflect.
For more information, see Shrinking Kotlin libraries and applications using Kotlin reflection with R8 on Medium. When you build the debug version of your app using Android Gradle plugin 4.
The cleanBuildCache task and the android. The android. Starting with this release, fields from R classes are no longer kept by default , which may result in significant APK size savings for apps that enable code shrinking.
This should not result in a behavior change unless you are accessing R classes by reflection, in which case it is necessary to add keep rules for those R classes. The experimental flag android. Set in the gradle. For library projects only, the BuildConfig. Additionally, these values were discarded during manifest merging. In a future version of Android Gradle plugin, the versionName and versionCode properties will also be removed from the DSL for libraries.
You can set the path to your local NDK installation using the android. If you use this property together with the android. Writing code in comment? Please use ide. Load Comments. What's New. Most popular in Android. ExoPlayer in Android with Example.
