我正在尝试在卸载应用程序之前向应用程序广播意图。为此，我在 SO 中研究并遵循了一些答案。我能够在安装时获得结果，但是当我从我的应用程序回到家时，由于 onStop 说，应用程序强制关闭

java.lang.RuntimeException: Unable to stop activity {com.xxx.xxxx}: java.lang.IllegalArgumentException: Receiver not registered: com.xxxx.xxxx.xxxxxx$1@4149f7a8

我所做的是，

public class AndroidTabLayoutActivity extends TabActivity
{                                
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
    intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL);
    intentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED);
    intentFilter.addDataScheme("package");
    registerReceiver(NewPackageReceiver, intentFilter);
  }
  private BroadcastReceiver NewPackageReceiver = new BroadcastReceiver()
  {
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Log.d("DEBUG", " test for application install/uninstall");
        Toast.makeText(AndroidTabLayoutActivity.this,
                "App Install/Uninstall", Toast.LENGTH_LONG).show();
    }

   };
    @Override
   protected void onStop()
   {
    super.onStop();
      unregisterReceiver(NewPackageReceiver);

   }
  }

我的清单是

  <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />
<uses-permission android:name="android.permission.SET_TIME_ZONE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_REMOVED"/>

<application
    android:icon="@drawable/locksettings"
    android:label="Locksettings" >
    <receiver android:name=".NewPackageReceiver">
    <intent-filter>
       <category android:name="android.intent.category.DEFAULT" />
        <action android:name="android.intent.action.PACKAGE_ADDED"  />
        <action android:name="android.intent.action.PACKAGE_CHANGED" />
        <action android:name="android.intent.action.PACKAGE_INSTALL" />
        <action android:name="android.intent.action.PACKAGE_REMOVED" />
        <action android:name="android.intent.action.PACKAGE_REPLACED" />
        <data android:scheme="package"/>
    </intent-filter>
</receiver>
</application>

在启动应用程序之前，我收到了安装日志消息。当我从应用程序回家时，应用程序正在强制关闭。任何人都可以指出我哪里出错了吗？
