My Problem as follows:
Since I added into webview "file:///android_asset/index.html" to load from, it crashes at startService(new Intent(this, TimeService.class));. If startService commented out. It works fine. When it is used, but I give webview a address like www.google.de, everything works fine. I am using API Level 26 for developing. Unfortunately I can not resolve this issue by now.
Java Code:
MainActivity.webView.loadUrl("file:///android_asset/index.html");
MainActivity.webView.getSettings().setJavaScriptEnabled(true);
MainActivity.webView.getSettings().setUseWideViewPort(true);
MainActivity.webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
//tel nummer support
if (url.startsWith("tel:") || url.startsWith("sms:") || url.startsWith("smsto:") || url.startsWith("mms:") || url.startsWith("mmsto:"))
{
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));
startActivity(intent);
return true;
}
//email support
if(url.startsWith("mailto:")){
Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse(url));
startActivity(i);
}
view.loadUrl(url);
return true;
}
});
startService(new Intent(this, TimeService.class));
