This event makes me think I forgot everything about programming in Java, as a NPE is thrown without any variable set to null.
In the next code how is it possible that the process reach the catch clause with e equal to NPE if neither msg nor mqttAndroidClient are null?
BTW, MqttAndroidClient is not supposed to throw a NPE according to MQTT documentation.
public class MainActivity extends AppCompatActivity {
MqttAndroidClient mqttAndroidClient;
final String serverUri = "tcp://iot.eclipse.org:1883";
String clientId = "ExampleAndroidClient";
final String publishTopic = "location";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mqttAndroidClient = MqttClientSingleton.getMqttClient(getApplicationContext(), serverUri, clientId);
mqttAndroidClient.setCallback(new MqttCallback() {
#Override
public void connectionLost(Throwable cause) {
try {
mqttAndroidClient.connect();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
#Override
public void messageArrived(String topic, MqttMessage message) throws Exception {
}
#Override
public void deliveryComplete(IMqttDeliveryToken token) {
}
});
mqttAndroidClient.connect();
try {
MqttMessage msg = new MqttMessage("test".getBytes());
mqttAndroidClient.publish(publishTopic, msg);
} catch (Exception e) {
throw new RuntimeException(e);
}
;
}
}
This is the MqttClientSingleton
import android.content.Context;
import org.eclipse.paho.android.service.MqttAndroidClient;
/**
* Created by storassa on 4/30/17.
*/
public class MqttClientSingleton {
private static MqttAndroidClient client;
public static MqttAndroidClient getMqttClient(Context c, String uri, String id) {
if (client == null) {
client = new MqttAndroidClient(c, uri, id);
return client;
}
else
return client;
}
}
This is the logcat

I believe you can not initialize a TextView before runtime because the views are not set yet. Classes should be capitalized. Try this.
public class MainActivity extends AppCompatActivity{
private TextView txt;
private Count i;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txt = (TextView)findViewById(R.id.textView);
}
}
I am trying to change from one screen to another after a user has signed up. The user is created but I get a java.lang.NullPointerException when I call the view interface from the presenter.
Here is the part in the presenter that creates the user and prompts the change to a login screen.
public void signUp() {
postUserUseCase.setWyat_user(user);
subscription = postUserUseCase
.execute()
.subscribeOn(rx.schedulers.Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<User>() {
#Override
public void onCompleted() {
Log.d("complete","complete");
signUpView.showLoginScreen();
}
#Override
public void onError(Throwable e) {
}
#Override
public void onNext(User user) {
Log.d("next",user.getEmail());
}
});
}
SignupActivity implements the view interface's showLoginScreen method.
public class SignUpActivity extends AppCompatActivity implements SignUpView {
#Override
public void showLoginScreen() {
Intent loginIntent = new Intent(this,LoginActivity.class);
startActivity(loginIntent);
}
}
The user is created but I get a null pointer onCompleted.
EDIT:
This is different from What is a NullPointerException, and how do I fix it? because if I did the initializing of an interface I get a whole class with the methods that my activity will override. This is a view interface not a variable or a class.I just want to call on method.
EDIT 2: Logcat for the error.

I have found two posts about that subject: First, Second
But they did not help me.
My activity code. Note that I am using AppIntro:
public class RegistrationActivity extends AppIntro {
private AsyncTaskRegisterInBackground registerPushToken;
(...)
#Override
public void onDonePressed() {
(...)
if (regid.isEmpty()) {
registerPushToken = new AsyncTaskRegisterInBackground();
registerPushToken.setParams(activity, gcm, regid);
registerPushToken.execute();
}
(...)
}
#Override
public void onTaskCompleted(String responseRegid) {
try {
// load authToken from Server: JsonObjectRequest
builderOnFailureDialog = new MaterialDialog.Builder(activity)
.title(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_title))
.content(onFailureDialogContent)
.positiveText(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_positive_text))
.negativeText(getResources().getString(R.string.registrierung_dialog_registrieren_failure_retry_negative_text))
.onNegative(new MaterialDialog.SingleButtonCallback() {
#Override
public void onClick(#NonNull MaterialDialog dialog, #NonNull DialogAction which) {
activity.finish();
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
protected void onDestroy() {
super.onDestroy();
try {
onFailureDialog.dismiss();
onSuccessDialog.dismiss();
} catch (Exception e) {
Log.e("Activity.onDestroy()", e.getMessage());
}
}
}
Or is the reason for the problem the async task running in background?
call finish() inside runOnUiThread().
i.e.
replace
finish();
with
runOnUiThread(new Runnable() {
public void run() {
finish()
}
});
I've programmed a game for android, everything works fine, but now I want my app to have Google play Games services (leaderboards and achievements). I used the Google example code to log in to the Google services (no errors in the script), but every time I want to connect with my App in debug mode, I get this error:

And the App crashes. Here's my code for the MainActivity where I want it to connect:
public class MainActivity extends BaseGameActivity implements
GameHelper.GameHelperListener, View.OnClickListener {
public static int REQUEST_LEADERBOARD = 1002;
boolean mExplicitSignOut = false;
boolean mInSignInFlow = false;
GoogleApiClient mClient() {
return null;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
setRequestedClients(BaseGameActivity.CLIENT_GAMES | BaseGameActivity.CLIENT_APPSTATE);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button)findViewById(R.id.startbutton);
button.setOnClickListener (this);
Button highscorebutton = (Button)findViewById(R.id.highscorebutton);
highscorebutton.setOnClickListener(this);
findViewById(R.id.sign_in_button).setOnClickListener(this);
findViewById(R.id.sign_out_button).setOnClickListener(this);
}
public void onClick(View view) {
if(view.getId()==R.id.startbutton) {
startActivityForResult(new Intent(this, buttonActivity.class), 1);
} else if(view.getId()==R.id.highscorebutton) {
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)),REQUEST_LEADERBOARD);
} else if (view.getId() == R.id.sign_in_button) {
// start the asynchronous sign in flow
beginUserInitiatedSignIn();
}
else if (view.getId() == R.id.sign_out_button) {
// sign out.
signOut();
// show sign-in button, hide the sign-out button
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Games.Leaderboards.submitScore(getApiClient(), getString(R.string.the_best_players), resultCode);
if(requestCode==1) {
if(resultCode > leseHighscore()) {
schreibeHighscore(resultCode);
}
}
}
#Override
public void onSignInFailed() {
findViewById(R.id.sign_in_button).setVisibility(View.VISIBLE);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);
}
#Override
public void onSignInSucceeded() {
View a = findViewById(R.id.highscorebutton);
a.setVisibility(View.VISIBLE);
View b = findViewById(R.id.button3);
b.setVisibility(View.VISIBLE);
findViewById(R.id.sign_in_button).setVisibility(View.GONE);
findViewById(R.id.sign_out_button).setVisibility(View.VISIBLE);
}
}
Thanks, GoogleWelt
According to the official documentation, "Before any operation is executed, the GoogleApiClient must be connected"
When the user in not connected(signed in) and clicks to show leaderboards or achievements, it results in the exception thrown. Modify your code for launching the leaderboard like this:
} else if(view.getId()==R.id.highscorebutton) {
if (isSignedIn())
startActivityForResult(Games.Leaderboards.getLeaderboardIntent(getApiClient(), getString(R.string.the_best_players)), REQUEST_LEADERBOARD);
else showAlert("Please sign in to view leaderboards");
}
Use the same logic for showing achievements:
if (isSignedIn())
startActivityForResult(Games.Achievements.getAchievementsIntent(getApiClient()), REQUEST_ACHIEVEMENT);
else showAlert("Please sign in to view achievements");
Check the part where you are getting ApiClient i.e. getApiClient().
Write the code below to see if GoogleApiClient is Connected or not.
GoogleApiClient mGoogleApiClient;
if(mGoogleApiClient.isConnected()){
// good
}else{
//connect it
mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);
}
