HelloToSpatialite

HelloToSpatialite is a relatively simple 'hello world' application illustrating the usage of spatialite android.

I started with the [original spatialite android tutorial] (https://www.gaia-gis.it/fossil/libspatialite/wiki?name=spatialite-android-tutorial) making changes to bring this tutorial into the more recent Android Studio (v1.3) build environments.

I also deviated a bit from this example by:

  • embedding the sqlite database in the application (versus loading on external storage)
  • using a different sqlite database than in the tutorial
  • See my guide on recreating the source data from this app
  • using different SQL examples
  • See GeoDatabaseHandler.java

This example relies on the Android module Spatialite-Database-Driver. Therefore, you will also need to get a copy of that lib:

git clone https://github.com/kristina-hager/Spatialite-Database-Driver.git

This example assumes you've put the directory for 'Spatialite-Database-Driver' in the same directory as 'HelloToSpatialite'.

Changes to enable usage of Spatialite-Database-Driver

app/build.gradle

  • Add dependency on Spatialite-Database-Driver

compile project(':..:Spatialite-Database-Driver:spatialite-db-driver')

settings.gradle

include ':app', '..:Spatialite-Database-Driver:spatialite-db-driver'

task copyNativeLibs(type: Copy) {
    from(new File(project(':..:Spatialite-Database-Driver:spatialite-db-driver').projectDir, 'src/main/java/jniLibs')) {
        include 'armeabi/libjsqlite.so'
        include 'armeabi-v7a/libjsqlite.so'
    }
    into new File(buildDir, 'native-libs')
}
tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn copyNativeLibs }
clean.dependsOn 'cleanCopyNativeLibs'

tasks.withType(PackageApplication) { pkgTask ->
    //pkgTask.jniDir new File(buildDir, 'native-libs')
    pkgTask.jniFolders = new HashSet<File>()
    pkgTask.jniFolders.add(new File(buildDir, 'native-libs'))
}
