basic app to take username and password and register (registration works) but when i press the button for login, it crashes. Code for signin:

signin.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent1 = new Intent(getApplicationContext(), LoginActivity.class);
        startActivity(intent1);
    }
}

expected to see login scree, but keeps quitting to phone home screen.

CodePudding user response：

have you declared LoginActivity in your AndroidManifest.xml? If not, do it like this:

<activity
    android:name=".LoginActivity">
</activity>
