i am a new to android development so dont be harsh
I am creating an android application that contains a webview. The webview has many links to live stream.
After reading various posts, i understand that it is really difficult and complicated (as i have tried) to get the video played in webview itself as webview doesn't have/ support many features for video streaming
My question is: HOW DO I OPEN UP MXPLAYER AND PLAY THE STREAM WHENEVER THE USER SELECTS A SPECIFIC LINK IN THE WEBVIEW?
I am just testing this on my own device so want to keep it specific to mx player as i already have that installed
I have tried the following:
public class WebPageLoader extends Activity {
final Activity activity = this;
WebView webView;
private String pknamepro;
String homePage = "";
String specificWebURL = "";
public WebPageLoader(){
pknamepro = "com.mxtech.videoplayer.pro";
}
private void startMx(String url)
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setComponent(new ComponentName("com.mxtech.videoplayer.pro", "com.mxtech.videoplayer.pro.ActivityScreen"));
intent.setData(Uri.parse(url));
intent.putExtra("secure_uri", true);
startActivity(intent);
return;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webpageloader);
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setSupportZoom(false);
webView.getSettings().setBuiltInZoomControls(false);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setAppCacheEnabled(true);
webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress)
{
activity.setTitle("Loading...");
activity.setProgress(progress * 100);
if(progress == 100)
activity.setTitle(R.string.app_name);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
Toast.makeText(getApplicationContext(), "Internet connection down" + description, Toast.LENGTH_SHORT).show();
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
if (url.contains("rtmp")|| url.contains(specificWebURL) || url.startsWith("rtmpe")|| url.startsWith("udp")) {
startMx(url);
return true;
}
view.loadUrl(url);
return true;
}
});
webView.loadUrl(homePage);
}
protected void onSaveInstanceState(Bundle outState)
{
super.onSaveInstanceState(outState);
// Save the state of the WebView
webView.saveState(outState);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
super.onRestoreInstanceState(savedInstanceState);
// Restore the state of the WebView
webView.restoreState(savedInstanceState);
}
public void onBackPressed() {
if(webView.canGoBack() == true){
webView.goBack();
}else{
webView.goBack();
}
}
As you can see, i have tried it by checking the url as well as tried to hard code the url but neither work.
It seems as if it doesn't do any of the above checks and tries to play the video in webview it self because whenever i click on any of the links, a new page opens saying "Error loading player: No playable sources found" instead of opening mxplayer on my device.
In case someone else has the same question as mine, below is my solution that is working for me.
Intent myIntent;
PackageManager pm = getPackageManager();
try{
myIntent = pm.getLaunchIntentForPackage("com.mxtech.videoplayer.pro");
myIntent.setComponent(new ComponentName("com.mxtech.videoplayer.pro", "com.mxtech.videoplayer.ActivityScreen"));
myIntent.setDataAndType(Uri.parse(url), "application/x-mpegURL");
myIntent.putExtra("secure_uri", true);
myIntent.putExtra(EXTRA_DECODE_MODE, (byte)2);
if (null != myIntent)
this.startActivity(myIntent);
}
catch (ActivityNotFoundException e)
{
Toast.makeText(getApplicationContext(),
" stream not working ",
Toast.LENGTH_LONG).show();
}

I have built a website that streams mp3 playlists using javascript and created an android app that uses WebView to embed the site. Unfortunately the music stops when the phone sleeps. Is it possible to code the app to maintain the javascript executing to keep music playing while running in background? I would like it to function similar to Pandora as an example but not sure if this is possible using WebView.
try this, i test this code so keep music playing while running in background, maybe help you:
private WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView)findViewById(R.id.webview);
// Enable javascript
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
final Uri uri = Uri.parse(url);
return customUriHanlder(uri);
}
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
final Uri uri = request.getUrl();
return customUriHanlder(uri);
}
private boolean customUriHanlder(final Uri uri) {
Log.i("TAG", "Uri =" + uri);
final String host = uri.getHost();
final String scheme = uri.getScheme();
// you can set your specific condition
if (true) {
// Returning false means that you are going to load this url in the webView itself
return false;
} else {
// Returning true means that you need to handle what to do with the url
// open web page in a Browser
final Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);
return true;
}
}
});
// Load the webpage
webView.loadUrl("https://google.com/");
}
#Override
public void onPause() {
super.onPause();
webView.onResume();
}
#Override
public void onResume() {
super.onResume();
webView.onResume();
}
#Override
protected void onDestroy() {
super.onDestroy();
webView.onResume();
}
I recently implemented the shouldInterceptRequest method to detect when the link "http://sitemercado.com.br/valida" clicked to open it in the android browser instead of opening internally in the webview until it worked the link is opened in the browser but when I come back for the webview application, it is also loaded, I would like it to load only in the browser.
My code is the following:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pb = (findViewById(R.id.pb));
mWebView = findViewById(R.id.webview);
mWebView.setListener(this, this);
mWebView.loadUrl("https://www.sitemercado.com.br/frade");
mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
mWebView.setWebViewClient(new WebViewClient(){
#Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
Intent i = new Intent(MainActivity.this, off.class);
startActivity(i);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
finish();
}
});
mWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.sitemercado.com.br/valida")) {
return true;
}
String valida = "https://www.sitemercado.com.br/valida";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(valida));
startActivity(i);
Toast.makeText(getApplicationContext(), "1Detectou", Toast.LENGTH_SHORT).show();
return false;
}
});
Where am I going wrong?
Unless I'm mistaken, the following is just wrong:
mWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("www.sitemercado.com.br/valida")) {
return true;
}
String valida = "https://www.sitemercado.com.br/valida";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(valida));
startActivity(i);
Toast.makeText(getApplicationContext(), "1Detectou", Toast.LENGTH_SHORT).show();
return false;
}
});
You're getting the host of the URL, then comparing it to a full URL. That's never going to be equal.
Then you launch the link only if that statement is false? That's inverted, since you say in your question that you want it to launch in the browser only if the URL is /valida. The way you have it, no matter what URL you attempt to load, Android will launch a browser pointing to /valida.
Try this instead:
mWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getPath().contains("valida")) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
Toast.makeText(getApplicationContext(), "1Detectou", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
I am loading a website in webview,we have used Ajax in website and its working fine on web browser and mobile browser also but in android webview ajax is not working no error is there in the console.Here is my code:-
public class Activity_WebView extends AppCompatActivity implements
ConnectivityReceiver.ConnectivityReceiverListener {
WebView webview;
ProgressDialog pro_dialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setPluginState(WebSettings.PluginState.ON);
webview.setWebViewClient(new loadinsame());
pro_dialog = new ProgressDialog(Activity_WebView.this);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setDomStorageEnabled(true);
webview.getSettings().setAllowUniversalAccessFromFileURLs(true);
boolean connection = checkConnection();
if (connection) {
webview.loadUrl("website url");
} else {
Toast.makeText(Activity_WebView.this, "Sorry! Not connected to
internet", Toast.LENGTH_SHORT).show();
dialog_Show(webview, "Please check you Inernet connect and Reload.",
false);
}
}
#Override
public void onNetworkConnectionChanged(boolean isConnected) {
if (!isConnected) {
Toast.makeText(Activity_WebView.this, "Sorry! Not connected to
internet", Toast.LENGTH_SHORT).show();
}
}
private class loadinsame extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
pro_dialog.setCancelable(false);
pro_dialog.setMessage("Loading...");
pro_dialog.show();
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
pro_dialog.dismiss();
}
#Override
public void onReceivedError(final WebView webview, WebResourceRequest
request, WebResourceError error) {
super.onReceivedError(webview, request, error);
pro_dialog.dismiss();
// dialog_Show(webview, "Error Occur, Do you want to Reload?", true);
}
}
#Override
public void onBackPressed() {
if (webview.canGoBack()) {
webview.goBack();
} else {
super.onBackPressed();
}
}
private boolean checkConnection() {
boolean isConnected = ConnectivityReceiver.isConnected();
return isConnected;
}
#Override
protected void onResume() {
super.onResume();
MyApplication.getInstance().setConnectivityListener(this);
}
}
when i inspect the website in chrome using emulator, find that my ajax remain pending and then cancel after sometime.
Thanks in advance.
Just promoting #Jeff Thomas comment, by setting
mWebView.getSettings().setDomStorageEnabled(true);
worked!!
When i enabled the java script, its working.
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("");
myWebView.getSettings().setDomStorageEnabled(true);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebClient());
Solutions
If you want to load web url in WebView so you need follow my code It's code working fine and In web any type of script language used in web page.
public void webviewCallBack(String coverUrl) {
WebView WebView webView = (WebView) findViewById(R.id.web_view);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setPluginState(WebSettings.PluginState.ON);
webView.getSettings().setAppCacheEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.clearView();
webView.measure(100, 100);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.setWebViewClient(new WebViewClient() {
// For api level bellow 24
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d("weburl__", url);
if (url.startsWith("http") || url.startsWith("https")) {
// Return false means, web view will handle the link
return false;
} else if (url.startsWith("tel:")) {
// Handle the tel: link
handleTelLink(url);
// Return true means, leave the current web view and handle the url itself
return true;
}
return false;
}
// From api level 24
#RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
// Get the tel: url
String url = request.getUrl().toString();
Log.d("weburl_____", url);
if (url.startsWith("http") || url.startsWith("https")) {
// Return false means, web view will handle the link
return false;
} else if (url.startsWith("tel:")) {
// Handle the tel: link
handleTelLink(url);
// Return true means, leave the current web view and handle the url itself
return true;
}
return false;
}
});
// Load the url into web view
webView.loadUrl(coverUrl);
hoadler();
}
public void hoadler() {
Runnable task = new Runnable() {
public void run() {
material_design_progressbar.setVisibility(View.VISIBLE);
}
};
worker.schedule(task, 5, TimeUnit.SECONDS);
}
I hope this code is helpful for you!
Here is how to edit the AndroidManifes.xml:
Find AndroidManifest.xml file in application folder at:
android/app/src/main/AndroidManifest.xml
Locate the application subelement.
Add the following tag:
android:usesCleartextTraffic=”true”
The application subelement should now look like:
<application
android:name=”io.flutter.app.Test”
android:label=”bell_ui”
android:icon=”#`enter code
here`mapmap/ic_launcher”
android:usesCleartextTraffic=”true”>
Save the AndroidManifest.xml file.
Now im having trouble getting the hardware back button to work. The app loads fine as does page and everything else but as soon as i hit the phones back button it crashes then forces close. Google's instructions sucked also as i am a beginner and they presume you know a certain amount.
Please advise where i should place the code if it is in the wrong place and also if there is anything wrong with it itself.
Cheers!

Don't call super.onBackPressed AND finish(). Use just one of them.
EDITED: Write
webView = (WebView) findViewById(R.id.webview);
instead of
final WebView webView = (WebView) findViewById(R.id.webview);
Then declare
WebView webView
before your activity onCreate method.
You're getting crach beacause you're trying to use a WebView variable which is actually null.
I'm trying to make an app that opens all web pages of a certain site, for example www.yahoo.com, in the webview, but all other web pages in the defaultbrowser. Here is the code that I am using but can not quite get it work.
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("http://www.yahoo.com")) {
// This is my web site, so do not override; let my WebView load
// the page
return false;
}
// Otherwise, the link is not for a page on my site, so launch
// another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
It looks to me that this code should work, but when i load yahoo it still goes to an outside browser. Any help would be appreciated. Thanks!
Here is a different way to do it.
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
String urlHost = Uri.parse(url).getHost();
switch (urlHost) {
case "yahoo.com":
return false;
case "www.yahoo.com":
return false;
case "m.yahoo.com":
return false;
default:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
getHost() usually returns just the domain name, or sometimes with www. prefixed to it. It never contains an http:// protocol AFAIK. Try using:
if ((Uri.parse(url).getHost().equals("yahoo.com")) || (Uri.parse(url).getHost().equals("www.yahoo.com")) || (Uri.parse(url).getHost().equals("m.yahoo.com"))) {
//Your code
Try this it should help you
private WebView mWebview;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_yahoo);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
#SuppressWarnings("deprecation")
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
#TargetApi(android.os.Build.VERSION_CODES.M)
#Override
public void onReceivedError(WebView view, WebResourceRequest req, WebResourceError rerr) {
// Redirect to deprecated method, so you can use it in all SDK versions
onReceivedError(view, rerr.getErrorCode(), rerr.getDescription().toString(), req.getUrl().toString());
}
});
mWebview .loadUrl("http://www.yahoo.com");
setContentView(mWebview );
}
}
