android.content.ActivityNotFoundException：没有找到处理意图的活动{act=android.intent.action.VIEW dat=PendingIntent{}

Question

我正在尝试使用 PendingIntent 从我的应用程序中执行另一个应用程序。 我得到其他应用程序的待处理意图值并执行此操作（我得到了字符串类型的待处理意图值）

public class NotificationCrawlingService extends NotificationListenerService {

AppDatabase appDatabase;
WordDatabase wordDatabase;
NotificationDatabase notificationDatabase;
Context context;
PackageManager pm;
NotificationEntity ne;
AllFragment allFragment;
RecyclerViewAdapter rv;
List<NotiData> notiData;
NotificationEntity noti;
Notification notification;


@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return super.onStartCommand(intent, flags, startId);
}

@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    super.onNotificationPosted(sbn);
    context = getApplicationContext();
    appDatabase = AppDatabase.getAppDatabase(context);
    wordDatabase = WordDatabase.getWordDatabase(context);
    notificationDatabase = NotificationDatabase.getNotificationDatabase(context);
    pm = context.getPackageManager();
    notification = sbn.getNotification();
    Bundle extras = notification.extras;
    String pakage_name = sbn.getPackageName();
    String app_name = findApp_name(pakage_name);
    PendingIntent pendingIntent = notification.contentIntent;


Intent intent1 = new Intent(Intent.ACTION_VIEW, Uri.parse(pendingIntent));
        startActivity(intent1);
        

然而它不会工作。 在日志中显示此错误

可能是什么问题？

您不能像那样将PendingIntent转换为Uri 。 代替：

PendingIntent pendingIntent = notification.contentIntent;
Intent intent1 = new Intent(Intent.ACTION_VIEW, Uri.parse(pendingIntent));
startActivity(intent1);

你来做这件事：

PendingIntent pendingIntent = notification.contentIntent;
pendingIntent.send();

这将启动包装在PendingIntent中的Intent 。
