Getting started

This TRAFFIC module integrates the Traffic Flow Segment Data and Traffic Incident Details services in a convenient way for Android application development.

Add the TRAFFIC module to your Android project

Modify build.gradle (app/build.gradle)

Apply the following lines to your module’s dependency section in the build.gradle file (ex: app/build.gradle):

1//library required for traffic
2
3implementation("com.tomtom.online:sdk-traffic:{libversion}")

If you use more than one SDK library, make sure that all libraries have the same version.

Modify AndroidManifest.xml

IMPORTANT: This approach is now deprecated. Please follow Key initialization via static method to directly pass the API Key.

Edit the AndroidManifest.xml file and add the service key inside the &ltapplication> tag taken from Traffic API site.

1<meta-data
2            android:name="OnlineTraffic.Key"
3            android:value="your-tomtom-key" />

Key initialization via static method

The following method should be used to pass the API Key to a Traffic instance.

val trafficApi = OnlineTrafficApi.create(context, apiKey)

Enable Java 8 Support in the build.gradle file

1android {
2    compileOptions {
3        sourceCompatibility JavaVersion.VERSION_1_8
4        targetCompatibility JavaVersion.VERSION_1_8
5    }
6}

Logging

TomTom SDK Log level

In TomTom we are constantly working on the quality of our products. That is why it is very important to have logs as detailed as possible for our support team to provide accurate help or bugfixes. The Maps SDK for Android has an advanced mechanism to gather and send logs to our support team. To enable logging and specify a log level please add the following code to your app:

Example:

1@Override
2public void onCreate() {
3    super.onCreate();
4    LogUtils.enableLogs(Log.VERBOSE);

• android.util.Log.VERBOSE will print all logs from TomTom SDK.
• android.util.Log.DEBUG will print debug logs from TomTom SDK.

Note: Logs from the SDK libraries are disabled by default.

Collecting logs

TomTom log

Logs from an application can be collected into a file on the SD card.

LogUtils.collectLogsToFile(logsFilePath);

A special permission should be added into your AndroidManifest.xml file to save logs on the SD card. For example:

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

When the sdk-maps module is used, the problem with supporting runtime permissions is handled by the SDK with the following method:

1@Override
2public void onMapReady(@NonNull TomtomMap tomtomMap) {
3    tomtomMap.collectLogsToFile(SampleApp.LOG_FILE_PATH);
4}

1override fun onMapReady(tomtomMap: TomtomMap) {
2    tomtomMap.collectLogsToFile(SampleApp.LOG_FILE_PATH)
3}

Important: Since Android API level 23, it is required to ask the user for runtime permission to write into the SD card.

Register crash observer

Using the crash observer makes it possible to automate the process of preparing an email message with attached logs which were already collected and stored on the SD card. To do so, please register a crash handler with the following code. Crash observer doesn’t break your already-used handlers ( like Crashlitics).

LogUtils.registerCrashObserver(getApplicationContext(), Uri.parse("file://" + LOGCAT_PATH), CRASH_OBSERVER_EMAIL);

Bug report

To enable an advanced logging mechanism which collects detailed data from logcat like: threads, services, and phone states, please use the following code:

adb bugreport issue01

This produces an issue01.zip file.
