I have website using javascript geolocation api and want it to open in a webview. I set up these permissions in the manifest file:

    The line

    D/WebKit (22653): SQLite database failed to load from /CachedGeoposition.db

    is interesting

    Try setting the appropriate DB path in WebSettings.setDatabasePath as well, it could be that this is used as the root for the geo db path

    I know this is an old question but anyone with this issue might find interesting focusing on this function:

    mWebView.getSettings().setGeolocationDatabasePath(getFilesDir().getPath());

    Geolocation uses databases to persist cached positions and permissions between sessions. This call sets the location of the database.

    Instead of setting a fixed path as parameter you should get it dynamically calling:

    getFilesDir().getPath()

    I'll post a solution that worked for me in the hope that it might provide some ideas on where the error might be. It would also help if you could provide details about the device(emulator)/os on which you're testing.

    I tested on (with no errors):

    • (Emulator) Galaxy Nexus (2.3.3) (data/data/package.name/files/CachedGeoposition.db file created)
    • (Emulator) Galaxy Nexus (3.0) (data/data/package.name/files/CachedGeoposition.db file created)
    • HTC One S (4.1.1) (data/data/package.name/files/CachedGeoposition.db file created)
    • Galaxy S3 (4.3) (couldn't see the file since my phone is not rooted and there are some 'run-as' bugs on 4.3)
    • Nexus 7 (4.4.4) - the webview above KIT KAT has changed a bit and the file is no longer there, but no error was shown (even when providing a wrong 'databases' folder path)
    • (Emulator) Galaxy S4 (5.0) (same as on 4.4.4)

    AndroidManifest permissions (pretty much the same):

    <uses-permission android:name="android.permission.ACCESS_GPS" />
<uses-permission android:name="android.permission.ACCESS_ASSISTED_GPS" />
<uses-permission android:name="android.permission.ACCESS_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    Web view settings:

    WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDatabaseEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setGeolocationDatabasePath(getFilesDir().getPath());
webSettings.setGeolocationEnabled(true);

    Web chrome client (the same):

    webview.setWebChromeClient(new WebChromeClient(){
    @Override
    public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) {
        callback.invoke(origin, true, false);
    }
});

    Test html file for getting the geolocation:

    <!DOCTYPE html>
<html>
<head>
<script>
var x = document.getElementById("demo");

function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition, showError);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position) {
    var latlon = position.coords.latitude + "," + position.coords.longitude;
    document.getElementById("locationHolder").innerHTML = latlon;
}

function showError(error) {
    switch(error.code) {
        case error.PERMISSION_DENIED:
            x.innerHTML = "User denied the request for Geolocation.";
            break;
        case error.POSITION_UNAVAILABLE:
            x.innerHTML = "Location information is unavailable";
            break;
        case error.TIMEOUT:
            x.innerHTML = "The request to get user location timed out.";
            break;
        case error.UNKNOWN_ERROR:
            x.innerHTML = "An unknown error occurred.";
            break;
    }
}
</script>
</head>

<body>

<p id="demo">Click the button to get your position.</p>

<div id="locationHolder">No location</div>
<button onclick="getLocation()">Get position</button>

</body>
</html>

    Also, for a local test, you could created a file containing the html under '/assets/www/index.html' and use the following code to load it into the webview:

    try {
    String html = readAssetFile("www/index.html");
    webview.loadDataWithBaseURL(null, html, "text/html", "UTF-8", null);
} catch (IOException e) {
}

    Read asset file method:

    private String readAssetFile(String filePath) throws IOException {
    StringBuilder buffer = new StringBuilder();
    InputStream fileInputStream = getAssets().open(filePath);
    BufferedReader bufferReader = new BufferedReader(new InputStreamReader(fileInputStream, "UTF-8"));
    String str;

    while ((str=bufferReader.readLine()) != null) {
        buffer.append(str);
    }
    fileInputStream.close();

    return buffer.toString();
}

    I couldn't reproduce your error without providing a wrong hardcoded path to the 'databases' folder.
