I suppose that You call views methods from thread. You have login method in witch you probably call to dialog or other views .You cannot access from not main thread to ui elements. You have to use handler or asynck task.
May be you are talking about this
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(Name, email1);
editor.putString(Phone, passw);
editor.commit();
System.out.println("sharde :" +sharedpreferences.getString(Name, "def").toString()+ ", "sharedpreferences.getString(Phone, "def");
Getting values from SharedPreferences storage.
SharedPreferences sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
String emailString = sharedPreferences.getString("email", null);
String passwordString = sharedPreferences.getString("password", null);
In the onCreate method, first check whether the preferences has values for email and password.
if((emailString != null) && (passwordString != null)) {
//Populate the email and password edit texts using stored email and password values.
etEmail.setText(emailString);
etPassword.setText(passwordString);
}
Starting an activity should be performed in main(UI) thread. You can use Handler or runOnUiThread.
if(response.contains("success")){
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(MainActivity.this,"Login Success", Toast.LENGTH_SHORT).show();
Intent nextScreen = new Intent(getApplicationContext(), FeedBack.class);
//Sending data to another Activity
nextScreen.putExtra("email", email.getText().toString());
Log.e("n", email.getText()+"."+ email.getText());
startActivity(nextScreen);
}
});
}else{
showAlert();

Mainactivity.java
report1=(TextView)findViewById(R.id.report1);
report=(ImageView)findViewById(R.id.report);
report1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});
report.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});

I think you are doing mistake here :
if(data.equalsIgnoreCase("User Found")){
Toast.makeText(getApplicationContext(),"Login Success", Toast.LENGTH_SHORT).show();
Intent i = new Intent(getApplicationContext(), Home.class);
startActivity(i);
}
in place of getApplicationContext() write :
if(data.equalsIgnoreCase("User Found")){
Toast.makeText(Login.this,"Login Success", Toast.LENGTH_SHORT).show();
Intent i = new Intent(getApplicationContext(), Home.class);
startActivity(i);
I think you are missing
<activity
android:name="package_name.Home"></activity>
In AndroidManifest.xml
You must define all activities in AndroidManifest.xml.
EDIT
System.out.println("data :: "+data);
if(data.equalsIgnoreCase("User Found"))
{
Toast.makeText(getApplicationContext(),"Login Success", Toast.LENGTH_SHORT).show();
Intent i = new Intent(getApplicationContext(), Home.class);
startActivity(i);
}
else
{
Toast.makeText(getApplicationContext(),"User not found, check query", Toast.LENGTH_SHORT).show();
}

I think you forget to add the OAuth consumer keys and secrets into Assets in oauth_consumer.properties file, that you can get by registering your application with twitter. They have bundled keys so that you can test quickly, but it is strongly recommended that you change these keys. First, it is a security issue for your application and secondly sometimes our keys give errors because too many developers are testing.
SocialAuth Android is an Android version of popular SocialAuth Java library. Now you do not need to integrate multiple SDKs if you want to integrate your application with multiple social networks. You just need to add few lines of code after integrating the SocialAuth Android library in your app. Go to this socialauth-android. One of the best approach to integrate all social media.
Go to this link for better understanding socialauth-android .also, code available in Github

change the value to 0 in the onStop() method of the activity class which is called when your user navigates away from the app!
For anyone else in the future I'm using firebase so this is what I did:
if (firebaseAuth.getCurrentUser()!= null)
{
startActivity(new Intent(getApplicationContext(),NavActivity.class));
}
