Download

Add the Jitpack repository to your root build file. The way you do this depends on the Gradle plugin you are using.

If using Gradle plugin 7.0.0. or newer (default for new apps since Android Studio Artic Fox)

// in settings.gradle
dependencyResolutionManagement {
    ...
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

For older verions of Gradle:

// in project-level build.gradle
allprojects {
    repositories {
        maven { url 'https://jitpack.io' }
    }
}

Finally, in your dependencies list

dependencies {
    implementation 'com.github.ticofab:android-gpx-parser:2.3.1'
}

Dependencies

The following is an open github repo that has date and time handling. Keep in mind that the following dependency also has dependencies of its own.

• Joda DateTime for Android

Usage

In Java:

GPXParser parser = new GPXParser(); // consider injection
Gpx parsedGpx = null;
try {
    InputStream in = getAssets().open("test.gpx");
    parsedGpx = parser.parse(in); // consider using a background thread
} catch (IOException | XmlPullParserException e) {
    // do something with this exception
    e.printStackTrace();
}
if (parsedGpx == null) {
    // error parsing track
} else {
    // do something with the parsed track
    // see included example app and tests
}

In Kotlin:

val parser = GPXParser() // consider injection
try {
    val input: InputStream = getAssets().open("test.gpx")
    val parsedGpx: Gpx? = parser.parse(input) // consider using a background thread
    parsedGpx?.let {
        // do something with the parsed track
        // see included example app and tests
    } ?: {
        // error parsing track
    }
} catch (e: IOException) {
    // do something with this exception
    e.printStackTrace()
} catch (e: XmlPullParserException) {
    // do something with this exception
    e.printStackTrace()
}
