I am getting compile error in line .addOnCompleteListener(LoginActivity.this : Login Activity is not an enclosed class.
Am I doing anything wrong in below code?
Below is my code in Activity
public class LoginFirebase extends AppCompatActivity {
private FirebaseAuth auth;
Button btn_Login;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login_firebase);
btn_Login = (Button) findViewById(R.id.btn_Login);
btn_Login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(final View view) {
auth.signInWithEmailAndPassword("username", "password")
.addOnCompleteListener(LoginActivity.this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
}
})
}
});
}
}
Please replace LoginActivity to LoginFirebase .

I want to display my Firebase notification message in textviews in background mode, but it's only working and displaying in foreground mode.
I have already used broadcastReceiver. It is working, but only in the foreground. How can I make it work in background mode?

If I have created a deep link using the branch.io that opens a specific screen in my app. If this link is also available in my app and a user clicks on it, will it open my screen? or it will do nothing as the link I am trying to open from the app is pointing to the same app?
When you click on a Branch link within a webView in your App, you will have to handle the routing to the specific Activity, after reading the Branch link parameters.
Here is a sample Activity which contains a webView and and shows a couple of Branch links. When you click on a link in the webView it reopens the webview and displays the link parameters in a Toast message if a Branch link is clicked
public class MainActivity extends AppCompatActivity {
private WebView webView_;
private Button button_;
private String TAG = "WebViewController";
private Context context_;
private static final String URL_TO_LOAD = "https://evangelosg.github.io/index.html";
private static final String BRANCH_LINK_TO_LOAD = "https://ere6.app.link/b6sS0gsCfG";
#Override
protected void onNewIntent(Intent intent) {
Log.d("WebView", "onNewIntent");
setIntent(intent);
}
#Override
protected void onResume() {
super.onResume();
Branch branch = Branch.getInstance();
branch.initSession(new Branch.BranchReferralInitListener() {
#Override
public void onInitFinished(JSONObject referringParams, BranchError error) {
if (error == null) {
Log.d(TAG, referringParams.toString());
Toast.makeText(context_, referringParams.toString(), Toast.LENGTH_LONG).show();
if (referringParams.has(BundleExtraKeys.CLICKED_BRANCH_LINK)) {
try {
boolean clickedBranchLink = referringParams.getBoolean(BundleExtraKeys.CLICKED_BRANCH_LINK);
if (clickedBranchLink) {
//do stuff!
}
} catch (JSONException e) {
Log.d("BranchTrends", e.getMessage());
}
}
} else {
Log.i("MyApp", error.getMessage());
}
}
}, this.getIntent().getData(), this);
}
#Override
protected void onStart() {
super.onStart();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context_ = this;
setContentView(R.layout.activity_main);
webView_ = (WebView) findViewById(R.id.webView);
webView_.setWebViewClient(new BranchWebViewController("app.link", MainActivity.class));
webView_.loadUrl(URL_TO_LOAD);
button_ = (Button) findViewById(R.id.button);
button_.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
CustomTabsIntent customTabsIntent = builder.build();
customTabsIntent.intent.putExtra("branch", BRANCH_LINK_TO_LOAD);
customTabsIntent.intent.putExtra("branch_force_new_session", true);
finish();
customTabsIntent.launchUrl(MainActivity.this, Uri.parse(BRANCH_LINK_TO_LOAD));
}
});
}
public class BranchWebViewController extends WebViewClient {
private String myDomain_;
private Class activityToLaunch_;
BranchWebViewController(#NonNull String myDomain, Class activityToLaunch) {
myDomain_ = myDomain;
activityToLaunch_ = activityToLaunch;
}
#Override
public void onLoadResource(WebView view, String url) {
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
String url = request.getUrl().toString();
if (url.contains(myDomain_)) {
Intent i = new Intent(view.getContext(), activityToLaunch_);
i.putExtra("branch", url);
i.putExtra("branch_force_new_session", true);
finish();
startActivity(i);
} else {
view.loadUrl(url);
}
return true;
}
}
}
Once you read the link parameters you can route to the appropriate Activity based on the link parameters.
I want to connect to wampserver and toast a webpage content in android app by pushing button (btnget) but when I click the button it doesn't toast.where is the problem?
my page on the localhost is "ss.php"
this is the connect class:
public class Connect extends AsyncTask {
public String link="";
public Connect(String link){
this.link=link;
}
#Override
protected Object doInBackground(Object[] params) {
try{
URL url=new URL(link);
URLConnection connection=url.openConnection();
BufferedReader reader=new BufferedReader(new
InputStreamReader(connection.getInputStream()));
StringBuilder builder=new StringBuilder();
String line=null;
while((line=reader.readLine())!=null){
builder.append(line);
}
MainActivity.data=builder.toString();
}catch (Exception e){
}
return "";
}}
this is main activity class:
public class MainActivity extends AppCompatActivity {
public static String data="";
Button getData;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/*address of the webpage on localhost:http://IP/path */
new Connect("http://192.168.56.1/localhost/shop/ss.php").execute();
getData=(Button)findViewById(R.id.btnGet);
getData.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,data, Toast.LENGTH_SHORT).show();
}});
};
}
If I'm not mistaking the link to your site hosted locally on a WAMP instance should look something like this: http://LocalHost:8080/shop/ss.php (or another port number that you configured in wamp settings)

when user from list is clicked the window with clicked users is opened. At this moment url should change from http://localhost:8080/cms/#/users/list to http://localhost:8080/cms/#/user/3
for better understanding below is screencast from that code:
and now some job done, but still not ideal:
here is my gwtp configuration:
public class ClientModule extends AbstractPresenterModule {
#Override
protected void configure() {
bind(RestyGwtConfig.class).asEagerSingleton();
install(new Builder()//
.defaultPlace(ClientRouting.HOME.url)//
.errorPlace(ClientRouting.ERROR.url)//
.unauthorizedPlace(ClientRouting.LOGIN.url)//
.tokenFormatter(RouteTokenFormatter.class).build());
install(new AppModule());
install(new GinFactoryModuleBuilder().build(AssistedInjectionFactory.class));
bind(CurrentUser.class).in(Singleton.class);
bind(IsAdminGatekeeper.class).in(Singleton.class);
bind(IsUserLoggedGatekeeper.class).in(Singleton.class);
bind(ResourceLoader.class).asEagerSingleton();
}
}
As You can see I use tokenFormatter(RouteTokenFormatter.class)
how it can be achieved with gwtp framework?
One way to achieve this is to change the URL of your UserListPresenter to support passing in the user id as an optional parameter:
#NameToken("/users/{userid}")
public interface MyProxy extends ProxyPlace<UserListPresenter> {
}
You need to override the prepareFromRequest method of your UserListPresenter and there you check if the userid is set and open your modal window if it is.
#Override
public void prepareFromRequest(PlaceRequest request) {
String userid = request.getParameter("userid", "list");
if (userid != "list") {
# open modal
}
else {
# close modal
}
}
You also need to change the logic when you click your on a user in your list:
#Override
public void onOpenModal(OpenWindowEvent event) {
PlaceRequest placeRequest = new PlaceRequest.Builder()
.nameToken("/users/{userid}")
.with("userid", event.getUser().getId())
.build();
placeManager.revealPlace(placeRequest);
}
This will change the URL and open the modal.
