webview cannot load html file from sd card

Question

I'm trying to load a html file from sd-card. Note: -> if i load http://www.google.com it works. -> the file exists -> i have permissions for internet and WRITE_EXTERNAL_STORAGE

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    addB = (Button) findViewById(R.id.add);
    webComp = (WebView) findViewById(R.id.webC);

    WebSettings webSettings = webComp.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setSupportZoom(false);
    webSettings.setAllowFileAccess(true);
    webSettings.setLoadsImagesAutomatically(true);
    webSettings.setSavePassword(false);
    webSettings.setSaveFormData(false);
    webSettings.setJavaScriptEnabled(true);        

    webComp.setWebViewClient(new HelloWebViewClient());                    



    webComp.loadUrl("/sdcard/FMS/1/message.html");            



}

Thank you ! :)

Answer 1

Misca,

You shouldn't hard code the directory of the sdcard like that. Its typically at /mnt/sdcard/ but this is never assured. You should also always check if the sdcard exists and is mounted first!

You want to use the following:

if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){
    Log.d(TAG, "No SDCARD");
} else {
    webComp.loadUrl("file://"+Environment.getExternalStorageDirectory()+"/FMS/1/message.html");
}

Answer 2

I think the url is file:///sdcard/FMS/1/message.html
