Step 0: Setup Dev Environment

Required tools

Git [distributed version control system]

Ant [java based software build system]

Eclipse [integrated development environment]

Android SDK

ADT Plugin [Android Plugin for Eclipse]

Step 1: Install Salesforce Mobile SDK

Build and deploy new application $ cd native/SalesforceSDK

$ android update project –p .

$ cd ./firstnative

$ android update project –p .

$ ant clean debug

$ ant installd

In Just Five Minutes…

We have created a new application that leverages the Salesforce

Mobile SDK for Android.

Exploring the code

Key files

Import the project in Eclipse, have a look at:

AndroidManifest.xml

res/values/rest.xml

MainActivity.java

Login/logout

To talk to the Salesforce server you need a RestClient:

clientManager.getRestClient(…)

This call will automatically kick off the login flow if needed.

When you make request to the server using the RestClient,

your access token is automatically refreshed whenever it is

expired.

To log out simply call:

ForceApp..APP.logout(…)

REST calls

REST API (com.salesforce.androidsdk.rest.RestRequest)

getRequestForQuery

getRequestForSearch

getRequestForCreate

getRequestForDelete

getRequestForUpsert

getRequestForUpdate

getRequestForDescribe

Let’s add Search

Modify User Interface

Edit main.xml <EditText android:id="@+id/search_text"

android:layout_height="wrap_content" android:layout_width="200dp"

android:hint="@string/search_hint" android:inputType="text"/>

<Button android:id="@+id/run_search"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

android:text="@string/search_button"

android:onClick="onSearchContacts"/>

Edit strings.xml <string name="search_hint">Search contacts</string>

<string name="search_button">Search</string>

Hookup Server Call

Edit MainActivity.java

public void onSearchContacts(View v) {

TextView textView = (TextView) findViewById(R.id.search_text);

String searchText = textView.getText().toString();

String soql = "SELECT Name FROM Contact WHERE Name LIKE

'%" + searchText + "%'";

sendRequest(soql);

}

In Just A Few Minutes…

We have modified our application to do contact search…
