Android: How to check for three conditions (boolean variables) before continuing with the app?

I have an app that requires the detection of location services (FINE_LOCATION) which requires either data or wifi to be enabled as well as the Location or (GPS) to be enabled as well.
I have managed to work around this if one condition is disabled but what I need is if all three services are disabled the app should walkthrough the user to enable them all one after another.
Is there a way of creating a loop or some kind of variable listener to see if all conditions are met?

Retrofit MaltformedJsonException expected at line - android

I used Facebook Login in my app as registering. Facebook API part worked well and after I got parameters I saved them to session, too.
For second part, I create a user data in MySQL via PHP Slim Framework.
I posted body with Retrofit. After user authentication I got Facebook data perfectly.
Everything is good but somehow Retrofit works onFailure method instead of onResponse method. (I got a little "user added" message in response) And gives this error(below)

Change the Response from call, from UserFacebook to String or UserFacebook need a String parameter called user_added (depending on the json you are receiving)

How to display extracted data from Facebook in a textview

I wrote code for connecting with Facebook and extracting username,email ID and Profile link .All the extracted details displays in different activity on the click of a button.But I wanted it to display it in the same actiivty as soon the login process is completed successfully.which means I need to edit the code after onSuccess but I don't no how to get the code

To be Clear: All i wanted is to display the extracted details in the same activity after a successful login can you please help with it.?

please check the following code
protected void connectToFacebook() {

Get Email Api Facebook for Android

I trying get email of user but I can't. profile.getProperty("email").toString(), profile.getEmail()..
I don't find solution.
Thanks u.
private void updateUI() {
Profile profile = Profile.getCurrentProfile();
//if (enableButtons && profile != null) {
if (profile != null) {
System.out.println("Nombre: "+profile.getFirstName()+" "+profile.getLastName());
} else {
profilePictureView.setProfileId(null);
greeting.setText(null);
}
}

First you need to set permission like
loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday, user_friends"));
and in your Activity do this
private LoginButton loginButton;
CallbackManager callbackManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday"));
callbackManager = CallbackManager.Factory.create();
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
Log.v("LoginActivity", response.toString());
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
// App code
Log.v("LoginActivity", "cancel");
}
#Override
public void onError(FacebookException exception) {
// App code
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
