I'm trying to implement a new activity after a user logs into his/her account, but the app keeps crashing after sign in is complete

Question

I am trying to implement a new activity after a user logs into his account, but the app keeps crashing after sign in is completes. I am also trying to get this new activity to open the camera in order to scan a picture.

 // Methos to handleClick Event of Sign In Button
public void signIn(View V)
   {
        final Dialog dialog = new Dialog(HomeActivity.this);
        dialog.setContentView(R.layout.login);
        dialog.setTitle("Login");

        // get the Refferences of views
        final  EditText editTextUserName=(EditText)dialog.findViewById(R.id.editTextUserNameToLogin);
        final  EditText editTextPassword=(EditText)dialog.findViewById(R.id.editTextPasswordToLogin);

        Button btnSignIn=(Button)dialog.findViewById(R.id.buttonSignIn);

        // Set On ClickListener
        btnSignIn.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // get The User name and Password
                String userName=editTextUserName.getText().toString();
                String password=editTextPassword.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))
                {
                    startActivity(new Intent("com.xpro.salccregistry.SCANS"));
                }
                else
                {
                    Toast.makeText(HomeActivity.this, "User Name or Password does not match", Toast.LENGTH_LONG).show();
                }
            }
        });

        dialog.show();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    // Close The Database
    loginDataBaseAdapter.close();
}
}

Answer 1

Change this line

startActivity(new Intent("com.xpro.salccregistry.SCANS"));

to

startActivity(new Intent(CurrentAct.this, NextActivity.class));

and check.

PS: Make sure the NextActivity is declared in manifest file as follows:

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".FirstActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activty
        android:name="com.xpro.salccregistry.SCANS"/>
</application>

Hope this helps.
