I have this simple code, that makes a get to a webservice.
For some reason it cant connect and gives the error in the log unknownHostException
This is the code:
String URL = "http://services.sapo.pt/EPG/GetChannelList";
String result = "";
final String tag = "Data received: ";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button btnSearch = (Button)findViewById(R.id.btnSearch);
btnSearch.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v) {
callWebService();
}
});
} // end onCreate()
public void callWebService(){
HttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet(URL);
ResponseHandler<String> handler = new BasicResponseHandler();
try {
result = httpclient.execute(request, handler);
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
httpclient.getConnectionManager().shutdown();
Log.i(tag, result);
}
This is part of my manifest
<permission android:name="android.permission.INTERNET"/>
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".AndroidApp"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I found the solution.
I putted the internet permission using the GUI in manifest which added the tag
< permission android:name"android.permission.INTERNET"/>
Then by hand, i putted the correct tag that is:
< uses-permission android:name="android.permission.INTERNET" />
which is a different tag and it worked. GUI fail.
Not sure if you have already checked this, but please check if you are behind a proxy or firewall. Here is a way to configure the HttpClient for a proxy and official apache documentation.

I am sending images to firebase. but when my upload pictures method starts running, I get no auth token printed into my logcat couple of times. I tried using both camera and gallery, but they both make the same output even though my firebase storage rules are:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write;
}
}
}
And my code is:
if (fragment3.isAdded()) {
EditText plantdetails = (EditText) fragment3.getView().findViewById(R.id.plantdetails);

prefs.edit().putString("pldetails", plantdetails.getText().toString()).apply();
String pname = prefs.getString("plname","null");
String pdate = prefs.getString("pldate","null");
String petails = prefs.getString("pldetails","null");
plantss.setPlname(pname);
plantss.setPldate(pdate);
plantss.setPldetails(petails);

So does anyone know a solution for that, or is it just a bug, because I use the same exact code in another app and it works just fine.
EDIT: The other app I use uses a different database, not the same one.
I am new to firebase. I was using an old version code where the parameters i put were atleast working for the url. but now when link is clicked, the browser opens and its a 400 error that requested url was not found. it works with only the dynamic link
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Uri BASE_URI = Uri.parse("http://example.com/");
Uri APP_URI = BASE_URI.buildUpon().
appendQueryParameter("extra1", "value").build();
String encodedUri = null;
try {
encodedUri = URLEncoder.encode(APP_URI.toString(), "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Log.v("ENCODED URI: ", encodedUri);
Uri deepLink = Uri.parse("https://eh62u.app.goo.gl/y6N7/?link="+encodedUri);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, "");
intent.putExtra(Intent.EXTRA_SUBJECT, "GET TICKETS" );
intent.putExtra(Intent.EXTRA_TEXT, "Click here to get the booked tickets: " + deepLink);
startActivity(Intent.createChooser(intent, "Send Email"));
}
});
}
Main Activity OnCreate code:
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
FirebaseDynamicLinks.getInstance().getDynamicLink(getIntent())
.addOnSuccessListener(this, new OnSuccessListener<PendingDynamicLinkData>() {
#Override
public void onSuccess(PendingDynamicLinkData data) {
if (data == null) {
Log.d("NULL DATA ", "getInvitation: no data");
return;
}
// Get the deep link
Uri deepLink = data.getLink();
String requestId2 = deepLink.getQueryParameter("extra1");
// Handle the deep link
// [START_EXCLUDE]
Log.d("DEEP LINK URL ", "deepLink:" + deepLink);
if (deepLink != null) {
if(requestId2 == "value") {
Intent intent = new Intent(getApplicationContext(), Main2Activity.class);
startActivity(intent);
}
}
// [END_EXCLUDE]
}
})
.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.w("onFailure: ", "getDynamicLink:onFailure", e);
}
});
Android Manifest Code:
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">

</activity>

</application>
how do i put the parameter and then get it in the onSuccess? Thanks
The problem that i finally figured out by trial and error was the encoding part of the code. When i removed the :
encodedUri = URLEncoder.encode(APP_URI.toString(), "UTF-8");
part and just passed APP_URI to the deep link like
Uri deepLink = Uri.parse("https://eh62u.app.goo.gl/y6N7/?link="+APP_URI);
or even constructing the link using builder as:
Uri.Builder URLbuilder = new Uri.Builder()
.scheme("https")
.authority(Constants.DOMAIN)
.path("/")
.appendQueryParameter("link", getBaseUri(value))
.appendQueryParameter("apn", context.getPackageName());
It worked. No Problems. Retrieving the parameter was the usual.
I made a basic server in eclipse:
Server server;
int tcp = 8885, udp = 8885;
public ServerMain() {
server = new Server();
server.addListener(new Listener() {
public void connected(Connection c) {
System.out.println("Connection made");
}
public void received(Connection c, Object p) {
}
public void disconnected(Connection c) {
System.out.println("Disconnection made");
}
});
server.start();
try {
server.bind(tcp, udp);
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
new ServerMain();
}
Then I created my client in android studio. I installed the library correctly. (According to google) I put the Kryonet jar into the libs folder and then rebuilt the project. I could then use Kryonet classes. Here is my code for my client:
Client client;
String ip = "MY.IP.ADDRESS";
int tcp = 8885, udp = 8885;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "Start");
client = new Client();
client.addListener(new Listener() {
public void received(Connection c, Object p) {
}
});
client.start();
try {
client.connect(5000, ip, tcp, udp);
Log.i(TAG, "conected");
} catch(IOException e) {
Log.i(TAG, "Error: " + e.getMessage());
}
}
It's the exact same code I would use in a normal Java client except now it's running directly from my android device. I get this error:
Error: Unable to connect to: /MY.IP.ADDRESS:8885
It cannot connect to my IP even though I port forwarded it and all. Why won't it connect? I have read online to add in this to my manifest file:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
So, I did:
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Still to absolutely no avail. What am I doing wrong? (P.S. I have tried with both my network IP, and my public IP. I have no idea what I'm doing wrong, everything works fine with a normal Java program, but with an android app it bugs out.)
Try this code, it's working:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "Start");
client = new Client();
client.addListener(new Listener() {
public void received(Connection c, Object p) {
}
});
client.start();
new ConnectToServer.execute();
}
public class ConnectToServer extends AsyncTask<String, int[], String>
{
#Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
try {
client.connect(5000, ip, tcp, udp);
Log.i(TAG, "conected");
} catch(IOException e) {
Log.i(TAG, "Error: " + e.getMessage());
return null;
}
}
}
I cant get registration ID for all the devices.
The manifest is good and i add all premission.
the Sender_ID is good.
the device has an account logged in. (Google account).
the code below is the activity which handles with the GCM device register.
Please help me!

The app opens in emulator with a screen showing a login button. But on login button click it is throwing regular errors now while the app was working few hours ago...
Can anyone suggest what could have been the problem .. ?
You probably don't have an internet connection in your emulator.
Open up a browser within the emulator and enter "http://api.twitter.com". This probably won't work. Do the same on your local pc it should work there.
