WebSettings settings = webView.getSettings(); settings.setJavaScriptEnabled(true);
settings.setJavaScriptCanOpenWindowsAutomatically(true);
...
settings.setDatabaseEnabled(true);
settings.setDatabasePath("/data/data/your.package.name/database_name");

然后需要继承onExceededDatabaseQuota它在WebChromeClient 里面

public void onExceededDatabaseQuota(String url, String
databaseIdentifier, long currentQuota, long estimatedSize, long
totalUsedQuota, WebStorage.QuotaUpdater quotaUpdater) {
quotaUpdater.updateQuota(204801);
}

<?php

header('Content-type: application/vnd.google-earth.kml+xml');
echo '<kml xmlns="http://www.google.com/earth/kml/2">';
echo '<Placemark>';
echo '<name>Google Inc.</name>';
echo '<description>1600 Amphitheatre Parkway, Mountain View, CA 94043</description>';
echo '<Point>';
echo '<coordinates>-122.0841430, 37.4219720, 0</coordinates>';
echo '</Point>';
echo '</Placemark>';
echo '</kml>';
?>
然后

final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=http://website.com/kml_gen.php"));
startActivity(myIntent);
