應用程序意圖在啟動時不為空

Question

在應用程序啟動意圖不為空。 我不知道為什么

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener{

/**
 * Views
 */
private ListView listView;


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

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);



Bundle bundle = getIntent().getExtras();
     if (bundle == null)
        Log.d("***DEBUG****", "Intent was null");
    else
        Log.d("**** DEBUG ***", "Intent not null");

關閉並重新打開我的應用程序拋出該意圖不為空：D/***DEBUG****：意圖不為空

通過添加 if(getIntent().getStringExtra("type")==null) 解決了我的問題
