NullPointerException due to long press on TextView

I found this strange error thanks to Crashlytics and it happened with the Samsung G386T. The Android application includes new android.support.v7 class classes to include a toolbar component. Unfortunately the error is very "generic" and it does not name the classes in my application where the error was started.

An example of a user activity declaration:

public class AccessAccountActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.access_acount_activity);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    if (toolbar != null) {
        toolbar.setLogo(R.drawable.ic_toolbar);
        setSupportActionBar(toolbar);
    }

    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.setTitle(getString(R.string.app_name));
        actionBar.setDisplayHomeAsUpEnabled(true);
    }
}

}

Gradle (Android Studio):

compile 'com.android.support:appcompat-v7:21.0.2'

Hi you have to use return value for longClick (TRUE)



editText.setOnLongClickListener(new View.OnLongClickListener() {
                    @Override
                    public boolean onLongClick(View v) {
                        return true;
                    }
                });

Check if you are doing some other action in the textview..i ran into a similar problem and I found out that along with the long print I was doing another action (like showing a dialog, etc.), due to which this error was occurring. try not to do this .. or set a timer. Please note that for me this only happened on the Lollipop versions of Samsung reported by the crashes.
