First in onCreate() we will set our WebView:
private WebView mWebView;
private ScrollView mScrollView;
public static final long DELAY_TIME = 1000;
private long mTime;
...
mWebView = findViewById(R.id.webView);
mWebView.loadUrl("http:///www.alexandroid.net");
Enable JavaScript:
WebSettings webViewSettings = mWebView.getSettings(); webViewSettings.setJavaScriptEnabled(true);
Create a method that would invoke our JavaScript code:
private void invokeJavaScriptCode(String code) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
mWebView.evaluateJavascript(code, null);
} else {
mWebView.loadUrl(String.format("javascript:%s", code));
}
}
