Writing your first app and seeing it running on your phone is only half the fun when it comes to Android. Head over to http: Setting Up Your Development Environment Java developers, especially those using Eclipse, will have an easy transition to the Android development world.
Android development is supported on the three major operating systems: You can download the specific JDK for your system from http: Android SDK Tools available from http: Take note where this is installed or unzipped for the next step.
Select Developer Tools and click Next, and Next again when presented with the items to be installed. Read and accept the license terms, and click Finish. When the installation is complete, restart Eclipse. Now configure the installed plugin by clicking on the Window menu and selecting Preferences.
Click Apply, then OK. Using the tools now installed, you need to install the SDK components. Launch the manager and select Available packages. Running the Emulator Now that you have all the tools required to started developing and running Android apps, you need to create a virtual device for your apps to run on in the Android Emulator.
You can also create multiple AVDs to test against, which comes in handy when you want to test your app on different-sized screens and various versions of the SDK. Give the device a name and select the target SDK from the drop-down.
Creating a Project Leaving the Emulator running, restart Eclipse so as to create our first Android project. Fill in the Project and Application names, and then enter a package name for the app. This package will not only become the top-level Java package for your source files, but also provides a unique identifier for your app.
No two apps can have the same package identifier installed on the phone at the same time, and the same goes for apps submitted to the Android Market.
With Create Activity selected, provide a name for the Java class that will become the entry point to your app, and click Finish. Explore the contents of the generated project. You will find various Java, XML, and configuration files. This is a good time to explain three key concepts used in Android app development.
The Activity will display a user interface in the supplied Window, and interact with the user to perform the task. A single Activity could be displaying a list of emails or showing a map of the current location. Typically, multiple Activities together form a complete Android application.
The generated Activity extends from the class android. Activity and overrides a single method, onCreate.
Activities are driven by events coming from the Android operating system, moving the Activity through different stages of its life cycle. The onCreate method is called when the Activity is being created with the intention of being the current running Activity.
This is achieved using the concept of Intents and Intent Filters. Activities can create Intents as a way of passing responsibility for a task onto other Activities. This can be either within the same app such as going from an Activity that displays a list of contacts to an Activity that displays the details of the single selected contact or out to an external app when, for example, you want to display a PDF using an installed PDF viewer.
Activities advertise their abilities to handle combinations of actions and data types through Intent Filters. If two apps advertise the same ability, Android will prompt the user to select which one they want to use.
The Intent is run, and can make the selection the default as an option. While the app is loading or the emulator starts up again if you closed ityou should add some of the Android-specific views to your current Eclipse perspective.
From the Devices view, you can see any emulators or phones you have plugged into your system that are available to debug apps on. This view is extremely useful for debugging your apps. It allows you to create filters, so you can switch between seeing different levels of logging warning, debug, fatal and different tags.Do I need an IDE to develop Android apps?
If you want to get in and start writing code, the Eclipse + ADT is about as seamless as you can find.
1, 7 8. add a comment | up vote 0 down vote. You could develop without a IDE for android has the Android SDK supports command line arguments. And you could use a your code .
You can read the documentation for the grade build system for Android in yunusemremert.com After that you can look into gradle exactly and just build everything from scratch. But honestly, seeing a premade project and copying it is way faster.
For example, if you need to make use of the Native Development Kit for apps like games (hint: if you need it, you probably already know you need it), Eclipse is mandatory.
Then select Documentation, SDK Platform Android , and Samples for SDK API 9; click Install Selected. Running the Emulator.
Now that you have all the tools required to started developing and running Android apps, you need to create a virtual device for your apps to run on in the Android Emulator.
Developing without Android Studio (yunusemremert.comddev) submitted 3 years ago by [deleted] I am just wondering is there a ide way to develop apps without using Android Studio? I mean my computer would not support much a resource hungry ide Ain't got the money for i7. Please don't use Eclipse.
Move on to Android Studio. Sadly these tutorial seems to be out of date, the links to the Android SDK now go to Android Studio and apparently Eclipse is no longer supported by Android.
The Elipse page says: "Open yunusemremert.com the top of the window, click Window -> Android SDK and AVD Manager.".
