启用/禁用android.nfc.action.TECH_DISCOVERED IntentFilter

Question

我想根据用户的设置选择禁用android.nfc.action.TECH_DISCOVERED IntentFilter，以避免出现选择应用程序对话框。

为此，我在我的Android Manifest文件中创建了一个活动别名，并通过PackageManager更改了它的状态：

Anroid Manifest File

<activity
    android:name=".activities.ActivitySplash"
    android:configChanges="orientation"
    android:label="@string/app_name"
    android:launchMode="singleTask"
    android:screenOrientation="portrait">
    <intent-filter>
        <action android:name="android.intent.action.VIEW"/>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity>
<activity-alias
    android:name=".AliasActivitySplash"
    android:targetActivity=".activities.ActivitySplash"
    android:exported="true"
    android:enabled="true">
    <intent-filter>
        <action android:name="android.nfc.action.TECH_DISCOVERED"/>
    </intent-filter>
    <meta-data
        android:name="android.nfc.action.TECH_DISCOVERED"
        android:resource="@xml/techlist"/>
</activity-alias>

Activity Alias State Management:

public void enableAlias() {
    int newState = PackageManager.COMPONENT_ENABLED_STATE_ENABLED;
    _packageManager.setComponentEnabledSetting(new ComponentName(_packageName, _packageName + "." + 
    "AliasActivitySplash"), newState, PackageManager.DONT_KILL_APP);
}
public void disableAlias() {
    int newState = PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
    _packageManager.setComponentEnabledSetting(new ComponentName(_packageName, _packageName + "." + 
    "AliasActivitySplash"), newState, PackageManager.DONT_KILL_APP);
}  

每次我尝试更改别名状态时，都会得到一个java.lang.SecurityException。我读过将应用程序安装为系统应用程序应该可以解决这个问题。

捕获到异常：

我做错了什么吗?或者有没有其他方法可以做到这一点？

我终于解决了这个问题。问题是我获取包名的方式。我的应用程序有多个版本配置，我试图禁用/启用设备上安装的其他版本的组件
