Installation | Search SDK | Android

To use the Search SDK, you'll need to configure your credentials and add the SDK as a dependency.

Configure credentials

Before installing the SDK, you will need to gather the appropriate credentials. The SDK requires two pieces of sensitive information from your Mapbox account. If you don't have a Mapbox account: sign up and navigate to your Account page. You'll need:

A public access token: From your account's tokens page, you can either copy your default public token or click the Create a token button to create a new public token.
A secret access token with the Downloads:Read scope.
1. From your account's tokens page, click the Create a token button.
2. From the token creation page, give your token a name and make sure the box next to the Downloads:Read scope is checked.
3. Click the Create token button at the bottom of the page to create your token.
4. The token you've created is a secret token, which means you will only have one opportunity to copy it somewhere secure.

You should not expose these access tokens in publicly-accessible source code where unauthorized users might find them. Instead, you should store them somewhere safe on your computer and take advantage of Gradle properties to make sure they're only added when your app is compiled. Once this configuration step has been completed, you will be able to reference your credentials in other parts of your app.

Configure your secret token

To avoid exposing your secret token, add it as an environment variable:

Find or create a gradle.properties file in your Gradle user home folder. The folder can be found at «USER_HOME»/.gradle. Once you have found or created the file, its path should be «USER_HOME»/.gradle/gradle.properties. You can read more about Gradle properties in the official Gradle documentation.
Add your secret token your gradle.properties file:

MAPBOX_DOWNLOADS_TOKEN=YOUR_SECRET_MAPBOX_ACCESS_TOKEN

Configure your public token

There are many ways to configure your public access token. Many of the examples and code snippets on this site assume your token is stored in a file in your project with other string values. If you would like to manage your public access token this way, open your project's R.strings.xml file and add the following string resource, replacing YOUR_MAPBOX_ACCESS_TOKEN with your public Mapbox API token:

<string name="mapbox_access_token">YOUR_MAPBOX_ACCESS_TOKEN</string>

If you ever need to rotate your access token, you will need to update the token value in your R.strings.xml file.

Configure permissions

You can use the Manifest merge feature to reduce the need to include any SDK requirements in your application's manifest file. You'll need to add either the Fine or Coarse location permission if you plan to display a user's location on the map or get the user's location information. The user location permission should also be checked during runtime using the PermissionsManager.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Add the dependency

Mapbox provides the Search SDK via Maven.

To add the Search SDK as a dependency, you will need to configure your build to download the Search SDK from Mapbox directly. This requires a valid username and password.

Open your project in Android Studio.
Open up your module-level build.gradle file.

The Search SDK uses Java 8 features. To enable Java 8 in your project, add the following compileOptions:

android {
  ...
  // Configure only for each module that uses Java 8
  // language features (either in its source code or
  // through dependencies).
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
  // For Kotlin projects
  kotlinOptions {
    jvmTarget = "1.8"
  }
}

Make sure that your project's minSdkVersion is at API 21 or higher.
```
android {
  ...
  defaultConfig {
      minSdkVersion 21
  }
}
```
Add the dependency under dependencies. There are two options:
- Option 1: To use the Search SDK with pre-built UI components, add the Search UI SDK (mapbox-search-android-ui) dependency. This will also include Search Core (mapbox-search-android) automatically.
```
dependencies {
  implementation "com.mapbox.search:mapbox-search-android-ui:1.0.0-beta.34"
}
```
- Option 2: To use the Search SDK without pre-built UI components, add the Search Core (mapbox-search-android) dependency.
```
dependencies {
  implementation "com.mapbox.search:mapbox-search-android:1.0.0-beta.34"
}
```

Open up your project-level build.gradle file. Declare the Mapbox Downloads API's v2/releases/maven endpoint in the repositories block. To download the Search SDK, you must authenticate your request with a valid username and password. In the previous section, you added your secret token as a password in the gradle.properties file in your Gradle user home folder.

allprojects {
  repositories {
    maven {
      url 'https://api.mapbox.com/downloads/v2/releases/maven'
      authentication {
        basic(BasicAuthentication)
      }
      credentials {
        // Do not change the username below.
        // This should always be `mapbox` (not your username). 
        username = "mapbox"
        // Use the secret token you stored in gradle.properties as the password
        password = project.properties['MAPBOX_DOWNLOADS_TOKEN'] ?: ""
      }
    }
  }
}

Because you've edited your Gradle files, Android Studio will ask you whether you want to sync the Gradle files. You can sync now.

Add search to an app

Open the activity’s XML manifest file. Set permissions and reference the name of the Application you created in the last step:


<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
 
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:theme="@style/AppTheme"
>
 
<activity
android:name=".MainActivity"
android:exported="true">
 
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>

Open the activity’s XML layout file and add the following view:


<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
 
<EditText
android:id="@+id/query_edit_text"
android:layout_width="match_parent"
android:layout_height="56dp"
android:hint="Where to?"
android:paddingHorizontal="16dp"
/>
 
<com.mapbox.search.ui.view.SearchResultsView
android:id="@+id/search_results_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="56dp"
android:paddingVertical="16dp"
/>
</FrameLayout>

Create a new Activity or open an existing Activity and add the code below:

}
 
override fun beforeTextChanged(s: CharSequence, start: Int, count: Int, after: Int) {

override fun afterTextChanged(e: Editable) { /* not implemented */ }
})
 
if (!isPermissionGranted(permission.ACCESS_FINE_LOCATION)) {
ActivityCompat.requestPermissions(
this,
arrayOf(permission.ACCESS_FINE_LOCATION, permission.ACCESS_COARSE_LOCATION),
PERMISSIONS_REQUEST_LOCATION
)
}
}
 
private companion object {
 
private const val PERMISSIONS_REQUEST_LOCATION = 0
 
fun Context.isPermissionGranted(permission: String): Boolean {
return ContextCompat.checkSelfPermission(
this, permission
) == PackageManager.PERMISSION_GRANTED
}
}
}

Run your application and you will see a functional search UI. Begin typing in the search bar to see results:
