android - 运行时异常 : Unable to instantiate receiver android

Question

我是安卓新手。我在同一个 Activity 中定义了 BroadcastReceiver，甚至我在 AndroidManifest.xml 中输入了条目，但我遇到了异常。

public class CheckTicketReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        message = intent.getAction();

        if(message != null) {
            Toast.makeText(context, message, Toast.LENGTH_LONG).show();
            if(message.equals("100")) {
                intent = new Intent(); 
                intent.setComponent(new ComponentName("com.sec.android.wallet", "com.sec.android.wallet.ui.activity.ticket.ExternalTicketDetailViewActivity")); 
                // Ticket ID (mandatory) 
                intent.putExtra("TICKET_ID", ticketId); 
                // Bounce ID (optional), set as the current system timestamp in milliseconds 
                intent.putExtra("BOUNCE_ID", ""+System.currentTimeMillis()); 
                // RESULT_ACTION (mandatory) 
                intent.putExtra("RESULT_ACTION", "com.sample.partners.action.VIEW_TICKET_RESULT"); 
                startActivity(intent); 
            }
        }
    }
}

AndroidManifest.xml 中的接收器

<receiver android:name=".BrandDetailActivity$CheckTicketReceiver" android:enabled="true">
    <intent-filter>
        <action android:name="com.sec.android.wallet.action.CHECK_TICKET" />
    </intent-filter>
</receiver>
