Here is my FirstFragment Class

package com.example.bajraregistertesteclipse;

import android.app.Fragment;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;

public class FirstFragment extends Fragment {
LoginDataBaseAdapter loginDataBaseAdapter;
EditText loginTestUser,loginTestPassword;
String userName,password,confirmpassword;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

       View view = inflater.inflate(R.layout.firstfragment, container, false);


      loginTestUser=(EditText)view.findViewById(R.id.editTextUserNameToLogin);
      loginTestPassword=    (EditText)view.findViewById(R.id.editTextPasswordToLogin);
       Button btnLogin = (Button) view.findViewById(R.id.buttonSignIn); 

        btnLogin.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
            //  Toast.makeText(getActivity(),"BttonLoginPressed",Toast.LENGTH_SHORT).show();

                // get The User name and Password
                 userName=loginTestUser.getText().toString();
                 password=loginTestPassword.getText().toString();

              // fetch the Password form database for respective user name
                    String storedPassword=loginDataBaseAdapter.getSinlgeEntry(userName);

                    // check if the Stored password matches with  Password entered by user
                    if(password.equals(storedPassword))
                    {
                        Toast.makeText(getActivity(), "Congrats: Login Successfull", Toast.LENGTH_LONG).show();

                        // Intent intent = new Intent(getActivity(), Admin_Page.class);
                       //     getActivity().startActivity(intent);

                        Intent open=new Intent("com.example.bajraregistertesteclipse.ADMIN_PAGE");

                        getActivity().startActivity(open);
                        // startActivity(open);

                    }
                    else
                    {
                        Toast.makeText(getActivity(), "User Name or Password does not match", Toast.LENGTH_LONG).show();
                    }

            }

        });

   return view;
}


@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    loginDataBaseAdapter=new LoginDataBaseAdapter(getActivity());
     loginDataBaseAdapter=loginDataBaseAdapter.open();
}

}

My Mainfest.xml is :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 package="com.example.bajraregistertesteclipse"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="13"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

   <activity  
       android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.example.bajraregistertesteclipse.MAINACTIVITY" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        </activity>
    <activity android:name=".SignUp"></activity>
     <activity android:name=".Admin_Page">

     </activity>

</application>

Now my problem is Application crash when orientation change and When click to the button new activity Admin_Page should be initiatied but application crash.

Thank YOu in Advance!!!

Solution 1

android:configChanges="keyboardHidden|orientation"

add this in your manifest file in your activity.

Solution 2

<activity android:name=".SignUp"
android:configChanges="keyboardHidden|orientation|screenSize">

Add this line to all your activities to avoid crash with orientation changes. This will avoid the activity being loaded again and again on orientation changes.

---

For a little more information what you actually do with configChanges here the link to the Android documentation.

Lists configuration changes that the activity will handle itself. When a configuration change occurs at runtime, the activity is shut down and restarted by default, but declaring a configuration with this attribute will prevent the activity from being restarted. Instead, the activity remains running and its onConfigurationChanged() method is called.

Note: Using this attribute should be avoided and used only as a last resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.

And how to handle configuration changes you can find here.

ya thanks...why my application crash when i do Intent intent = new Intent(getActivity(), Admin_Page.class); getActivity().startActivity(intent);

[Mahesh]

What is the error that you are getting? I mean error in logcat

[Mahesh]

You are welcome. @Rohan Ale Please accept any answer that you find as correct so that this question wont remain unanswered.. :)

[Bhim Prasad Ale]

how can we destroy the previous activity. i.e when i sucessfully login then my new Activity start but when i press back button of moible i will directed towards my login page again which i want to destroy it. can you help me out ?

[Mahesh]

use finish(); before starting new activity

[Bhim Prasad Ale]

when i use finish(); ERROR: The method finish() is undefined for the type new View.OnClickListener(){

[Mahesh]

let us continue this discussion in chat

[Mahesh]

If it is a fragment then we need to use getActivity().finish(); otherwise activity_class_name.finish();

[Jithu]

Do you know any other method to manage this problem?? If you are using webview, css, etc related things, you cant use this method, because, you need to rearrange when orientation changes.

[Filip Luchianenco]

It's useless to answer in this form. Explain what you mean and how that affects the app and how it solves the described problem.

[Crapo Wolf]

This is the solution. You had to add this on your activity in manifest.

This is most likely going to crash after process death, see stackoverflow.com/questions/49046773/…
