我正在使用异步任务来创建加载屏幕，但是当我想将意图传递给主要活动时，应用程序崩溃......这里有一些代码：

 public class StartActivity extends Activity {
     protected boolean _active = true;
     protected int _splashTime = 5000;

     @Override
     public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.loading_screen);

    Thread splashThread = new Thread() {
        @Override
        public void run(){
            try {
                int waited = 0;
                while(_active && (waited <_splashTime)) {
                    sleep(100);
                    if(_active) {
                        waited +=100;
                    }
                }
            } catch(InterruptedException e) { 
            } finally {

                startActivity(new Intent("HNappActivity"));
                finish();

            }
        }
    };
    splashThread.start();
    }

这是清单：

  <activity
        android:name=".StartActivity"
        android:label="@string/title_activity_hnapp" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="HNappActivity"></activity>

StartActivity 类首先启动，它显示加载屏幕，然后它应该将意图传递给主要活动，但它崩溃了。

你需要改变：

    startActivity(new Intent("HNappActivity"));

到：

    startActivity(new Intent(StartActivity.this, HNappActivity.class));

此外，我假设它确实存在于您的项目中。

改变

<activity android:name="HNappActivity"></activity>

到

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

类名前的点很重要。

正如他们所说，您必须使用

  startActivity(new Intent(StartActivity.this, HNappActivity.class));
