Running Your App

If you followed the previous lesson to create an Android project, it includes a default set of "Hello World" source files that allow you to immediately run the app.

How you run your app depends on two things: whether you have a real device running Android and whether you're using Android Studio. This lesson shows you how to install and run your app on a real device and on the Android emulator, and in both cases with either Android Studio or the command line tools.

Run on a Real Device
________________________________________
If you have a device running Android, here's how to install and run your app.

Set up your device
1. Plug in your device to your development machine with a USB cable. If you're developing on Windows, you might need to install the appropriate USB driver for your device. For help installing drivers, see the OEM USB Drivers document.
2. Enable USB debugging on your device.
o On most devices running Android 3.2 or older, you can find the option under Settings > Applications > Development.
o On Android 4.0 and newer, it's in Settings > Developer options.

Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.

Run the app from Android Studio
1. Select one of your project's files and click Run from the toolbar.
2. In the Choose Device window that appears, select the Choose a running device radio button, select your device, and click OK .
Android Studio installs the app on your connected device and starts it.

Run the app from a command line
1. Change directories to the root of your Android project and execute:
ant debug
2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute:
adb install bin/MyFirstApp-debug.apk
3. On your device, locate MyFirstApp and open it.


Run on the Emulator
________________________________________
Whether you're using Android Studio or the command line, to run your app on the emulator you need to first create an Android Virtual Device (AVD). An AVD is a device configuration for the Android emulator that allows you to model a specific device.

Create an AVD
1. Launch the Android Virtual Device Manager:
o In Android Studio, select Tools > Android > AVD Manager, or click the AVD Manager icon in the toolbar.
o Or, from the command line, change directories to <sdk>/tools/ and execute:
android avd

Note: The AVD Manager that appears when launched from the command line is different from the version in Android Studio, so the following instructions may not apply.

www.nairaland.com/attachments/2021346_avd_pnged275778fc0c15dab8f6dd2e346eb03f
Figure 1. The AVD Manager main screen shows your current virtual devices.

2. On the AVD Manager main screen (figure 1), click Create Virtual Device.
5. In the Select Hardware window, select a device configuration, such as Nexus 6, then click Next.
6. Select the desired system version for the AVD and click Next.
7. Verify the configuration settings, then click Finish.

Run the app from Android Studio
1. In Android Studio, select your project and click Run from the toolbar.
2. In the Choose Device window, click the Launch emulator radio button.
3. From the Android virtual device pull-down menu, select the emulator you created, and click OK.
It can take a few minutes for the emulator to load itself. You may have to unlock the screen. When you do, My First App appears on the emulator screen.

Run your app from the command line
1. Change directories to the root of your Android project and execute:
ant debug
2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute:
adb install bin/MyFirstApp-debug.apk
3. On the emulator, locate MyFirstApp and open it.
That's how you build and run your Android app on the emulator!

How to Create a Project with Command Line Tools
________________________________________
If you're not using the Android Studio IDE, you can instead create your project using the SDK tools from a command line:
1. Change directories into the Android SDK’s tools/ path.
2. Execute:
android list targets
This prints a list of the available Android platforms that you’ve downloaded for your SDK. Find the platform against which you want to compile your app. Make a note of the target ID. We recommend that you select the highest version possible. You can still build your app to support older versions, but setting the build target to the latest version allows you to optimize your app for the latest devices.
If you don't see any targets listed, you need to install some using the Android SDK Manager tool. See Adding SDK Packages.
3. Execute:
4. android create project --target <target-id> --name MyFirstApp \
5. --path <path-to-workspace>/MyFirstApp --activity MyActivity \
6. --package com.example.myfirstapp
Replace <target-id> with an ID from the list of targets (from the previous step) and replace <path-to-workspace> with the location in which you want to save your Android projects.

Tip: Add the platform-tools/ as well as the tools/ directory to your PATH environment variable.
Your Android project is now a basic "Hello World" app that contains some default files.

Thats true. you can equally do sometin like event decoration and as a lesson teacher.


pico4421:
Today, we did be getting something new which i bet will change your financial life as a student and not only that, it will have to breed you up for the future on how you can earn a living from Little.

Below are the tmake money as a student.These researches, were all gotten from vaious platform ike the Myed.ng, business.org, imc.com and so many others and today, i find it wise to share these tips with you.

WHY DO YOU NEED THIS TIPS ?

As a student, you tend to face so many challenges, ranging from tution fee, hostel fee and other fee. Let me not even speak about those ones now, because you tend you pay for those ones once in a year But Do you Know that the money you use in Feeding and buying Materials Is even more greater then the amount you spend for school fees and other fees and obviously, they are the ones that tend to consume more cash.
What are these other challenges?
-Feeding
-Photocopying
-Departmental dues
-Hostel Dues
-Faculty dues…. Etc

1.Photography: The Photography business has grown from its state in the days to a renowned profession which people are making a fortune out of. Starting this business in small scale means youre not just making money at the moment but securing a strong financial future for yourself. You know how students especially the female folks love taking pictures, this is the perfect time to make maximum use of this opportunity. you don’t need much to start, just save a little money for a good camera, with a bit of creativity and you’re good to go. Please note that doing photography professionally requires just more than the previous requirements mentioned but this should be enough to get you started. you can also take passport photographs during school registrations.

2.Sale of Fashion Items: Interesting thing about this business is that you’d succeed no matter your gender. Both male and female wears rocks on Nigerian campuses and who else will succeed more if not their fellow students. I know of a guy who is living comfortably and paying school fees only by selling men under-wears, yes, Just men under wears, most of the times he travels out to the region where these boxer shorts are at a very low prize, buys them and bring them to his school. He sells these boxer shorts for virtually everybody in his region ranging from his lecturers down to his fellow students. I don’t want to go into details on how much these things cost, but its best you do your home work.

3.T-Shirt Customization: This business requires your creativity as a student. looking around you, you’ll notice students love fancy and funky stuffs. learning the art of this business means you’ll have fellow students begging you to collect their money for a t-shirt write up. You can learn this simple business during your stay at home/holiday. You can start in small scale by doing the write ups on your own T-shirt, friends will like it and ask you to even do for them. Just start something. Remember the “My Oga at the Top Saga”? you see those custom t-shirts? Need i say more? - See more at:

4.Online Registration: Yes, if you have a laptop and a bit of computer knowledge, i don’t know what stops you from enjoying both the pleasure and money derived from this Job. you can register virtually everything online. Course Registration, Post-UTME Registration, JAMB Registration, Job Application, etc. You can even make extra cash from typing assignments and projects for fellow students. Do i also need to tell you the thousands of Naira made during post UTME registrations? All the tools you need to make good money are all around you, you Just need to identify one and work your way through it. -

5.Website Design/Hosting: I’ll be a bit biased on this one because that’s what i do currently and don’t know if its suitable for students or not. But i can authoritatively tell you students are taping into the hidden money from this lucrative business. It may take a while to learn the entire concept of how this things work but its something you can easily do while you are home for holidays. Website Design may sound a bit complex so you might want to manage the little you get from setting up blogs for fellow students. This write up may not make sense to you because you don’t know a thing about website design, its why i’ll advice you to learn under anybody who is established in it already. Look around your campus, there are students who do well comfortably with this business, it wouldn’t hurt much to meet them to put you through.

Creating an Android Project

An Android project contains all the files that comprise the source code for your Android app.
In this lesson I will shows how to create a new project either using Android Studio or using the SDK tools from a command line.
Note: You should already have the Android SDK installed, and if you're using Android Studio, you should also have Android Studio installed.

Steps on how to Create a Project with Android Studio
________________________________________
1. Lunch your Android Studio,
In Android Studio, create a new project:
o If you don't have a project opened, in the Welcome screen, click New Project.
o If you have a project opened, from the File menu, select New Project.


www.nairaland.com/attachments/2006391_android_png9a1ca5310b1999c822550a7a154e2da1
Figure 1. Configuring a new project in Android Studio.


2. Under Configure your new project, fill in the fields as shown in figure 1 and click Next.
It will probably be easier to follow these lessons if you use the same values as shown.
o Application Name is the app name that appears to users. For this project, use "My First App."
o Company domain provides a qualifier that will be appended to the package name; Android Studio will remember this qualifier for each new project you create.
o Package name is the fully qualified name for the project (following the same rules as those for naming packages in the Java programming language). Your package name must be unique across all packages installed on the Android system. You can Edit this value independently from the application name or the company domain.
o Project location is the directory on your system that holds the project files.

3. Under Select the form factors your app will run on, check the box for Phone and Tablet.
4. For Minimum SDK, select API 8: Android 2.2 (Froyo).

The Minimum Required SDK is the earliest version of Android that your app supports, indicated using the API level. To support as many devices as possible, you should set this to the lowest version available that allows your app to provide its core feature set. If any feature of your app is possible only on newer versions of Android and it's not critical to the app's core feature set, you can enable the feature only when running on the versions that support it.

5. Leave all of the other options (TV, Wear, and Glass) unchecked and click Next.


Activities
An activity is one of the distinguishing features of the Android framework. Activities provide the user with access to your app, and there may be many activities. An application will usually have a main activity for when the user launches the application, another activity for when she selects some content to view, for example, and other activities for when she performs other tasks within the app.

6. Under Add an activity to your project, select Blank Activity and click Next.
7. Under Describe the new activity for your project, leave the fields as they are and click Finish.

Your Android project is now a basic "Hello World" app that contains some default files. Take a moment to review the most important of these:

app/src/main/res/layout/activity_my.xml
This is the XML layout file for the activity you added when you created the project with Android Studio. Following the New Project workflow, Android Studio presents this file with both a text view and a preview of the screen UI. The file includes some default settings and a TextView element that displays the message, "Hello world!"

app/src/main/java/com.mycompany.myfirstapp/MyActivity.java
A tab for this file appears in Android Studio when the New Project workflow finishes. When you select the file you see the class definition for the activity you created. When you build and run the app, the Activity class starts the activity and loads the layout file that says "Hello World!"

app/src/res/AndroidManifest.xml
The manifest file describes the fundamental characteristics of the app and defines each of its components. You'll revisit this file as you follow these lessons and add more components to your app.

app/build.gradle
Android Studio uses Gradle to compile and build your app. There is a build.gradle file for each module of your project, as well as a build.gradle file for the entire project. Usually, you're only interested in the build.gradle file for the module, in this case the app or application module. This is where your app's build dependencies are set, including the defaultConfig settings:
• compiledSdkVersion is the platform version against which you will compile your app. By default, this is set to the latest version of Android available in your SDK. (It should be Android 4.1 or greater; if you don't have such a version available, you must install one using the SDK Manager.) You can still build your app to support older versions, but setting this to the latest version allows you to enable new features and optimize your app for a great user experience on the latest devices.
• applicationId is the fully qualified package name for your application that you specified during the New Project workflow.
• minSdkVersion is the Minimum SDK version you specified during the New Project workflow. This is the earliest version of the Android SDK that your app supports.
• targetSdkVersion indicates the highest version of Android with which you have tested your application. As new versions of Android become available, you should test your app on the new version and update this value to match the latest API level and thereby take advantage of new platform features. For more information.

Note also the /res subdirectories that contain the resources for your application:

drawable-hdpi/
Directory for drawable objects (such as bitmaps) that are designed for high-density (hdpi) screens. Other drawable directories contain assets designed for other screen densities. Here you'll find the ic_launcher.png that appears when you run the default app.

layout/
Directory for files that define your app's user interface like activity_my.xml, discussed above, which describes a basic layout for the MyActivity class.

values/
Directory for other XML files that contain a collection of resources, such as string and color definitions. The strings.xml file defines the "Hello world!" string that displays when you run the default app.

How to run the app,
How to Create a Project with Command Line Tools. continue to the next lesson.
