I've tried the answer in this posts but I kept getting the same exception
com.parse.ParseRequest$ParseRequestException: invalid session token

For future reference all I had to do is uninstall the application from the emulator than run it again and the problem was solved.

You need to logout the user in Login\Signup view controllers.
Try this in viewDidLoad:
ParseUser.getCurrentUser().logOut();

Now when I click on Save button nothing happens..
So can somebody help me out from this situation.
Thanks in advance.

Inside onClick function, use switch-case on the view Id as below:
#override
public void onClick(View view) {
switch(view.getId()) {
case R.id.btnSave:
// Your custom save code goes here ...
break;
case R.id.btnBack:
// ...
break;
}
}

Try this code:
btnSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
StudentRepo repo = new StudentRepo(StudentDetail .this);
Student student = new Student();
student.name = txtEditName.getText().toString();
student.father_name = txtEditFather.getText().toString();
student.mother_name = txtEditMother.getText().toString();
student.age = Integer.parseInt(txtEditAge.getText().toString());
student.student_class = txtEditClass.getText().toString();
student.student_id =_student_id;
if (_student_id==0){
_student_id = repo.insert(student);
Toast.makeText(this,"New Student Insert",Toast.LENGTH_SHORT).show();
}
}
});
btnBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
instead of
btnSave.setOnClickListener(this);
btnBack.setOnClickListener(this);

Oh thanks to all of you to give time to my question and suggesting me to do to fix the bug.
But after reviewing all the code line to line I found that bug myself.
The bug was launching wrong activity in AndroidManifest.xml file.
To fix this I removed the tag from MainActivity tag and placed this to StudentDetail activity tag and everything started working fine.
The updated code was :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.studentregistration" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="com.example.studentregistration.StudentDetail"
android:label="#string/title_activity_entry_form" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Thanks once again to all.

Here the screen shot of output:
MainActivity Screen
Usermain Screen
the above two screens having the same theme. Please help me in this thanks in advance

I forgot to start activity with Intent. That's why the style is not applied.
have to change this
public void onClick(View v) {
setContentView(R.layout.activity_usermain);
}
with this one in MainActivity.java
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, Usermain.class);
startActivity(intent);
}
Its working good.

brother i also made an activity that wasn't much complex either just to test this issue but i didn't need to initiate any code. as u have described in the answer. It is working fine for me. All i did was change my Android Manifest file a bit and styles.xml.
after only these 2 changes i was good to go

Android: Application is crashing On Startup

I am a novice and I'm just creating a simple Android app in which there are 2 buttons that take you to different pages when clicked, which have different functions.
However, my app crashes on start-up, simply saying
Unfortunately [app name] has stopped

It's your manifest, replace the "last" activity in your manifest by this :
<activity
android:name=".Assistant"
android:label="#string/title_activity_preach_assistant"
android:parentActivityName=".MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.theocratichelper.MainActivity" />
</activity>
Your class name is Assistant and not PreachAssistant i presume.

Just replace the last activity in Android Manifest by this.
<activity
android:name=".Assistant"
android:label="#string/title_activity_preach_assistant"
</activity>

Trying to code an android app through eclipse to register bluetooth proximity, crashing on startup

I am writing an app that will eventually use Bluetooth to get a value for two devices' proximity to one another. I am currently trying to use buttons and onClick/onclicklistener etc to bring switch screens from the main UI to a log in or sign up page. Now my app is forcing close on start up and I'm not sure why. Thanks for any help!!

Move this code inside your onCreate method:
if (bluetooth != null) {
if (bluetooth.isEnabled()) {
String mydeviceaddress = bluetooth.getAddress();
String mydevicename = bluetooth.getName();
status = mydevicename + ":" + mydeviceaddress;
} else {
status = "Bluetooth is not Enabled.";
}
//etc...
Currently this code block is outside of any method of your activity and that is for sure not what you want to have.

to
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="Welcome"
android:textSize="20dip" >
</TextView>
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
this is because your < /TextView> was closed after fragment class so you got this error.
Also change here
startActivity(new Intent(LoginActivity.this,LoginSuccess.class).putExtra("usr",strUsername));
and also in your LoginSuccess Activity
Intent in = getIntent();
if (in.getStringExtra("usr") != null) {
final TextView setmsg = (TextView)findViewById(R.id.showmsg);
setmsg.setText("Welcome \n "+in.getStringExtra("usr"));
}
That means you have to declare this part in your manifest file...
<uses-feature android:glEsVersion="0x00020000" android:required="true/>
and must use latest updated Google Play Service.

Invalid session token on SignUp activity Android (Parse backend) - java

For future reference all I had to do is uninstall the application from the emulator than run it again and the problem was solved.

You need to logout the user in Login\Signup view controllers. Try this in viewDidLoad: ParseUser.getCurrentUser().logOut();
