用java给无activity应用写一个Service,拦截三方应用的广告通知,并在通知中显示正在运行,设置通知优先级让用户不可销毁通知的代码

好的,以下是代码示例:
1. 创建一个继承自Service的类,例如MyService:
```java
public class MyService extends Service {
private NotificationManager notificationManager;
private static final int NOTIFICATION_ID = 1;
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// 在此处添加拦截广告通知的代码
showNotification();
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
notificationManager.cancel(NOTIFICATION_ID);
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
private void showNotification() {
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "default")
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("正在运行")
.setContentText("点击查看详情")
.setPriority(NotificationCompat.PRIORITY_MAX)
.setOngoing(true);
Intent intent = new Intent(this, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("default", "Channel name", NotificationManager.IMPORTANCE_DEFAULT);
channel.setDescription("Channel description");
notificationManager.createNotificationChannel(channel);
}
notificationManager.notify(NOTIFICATION_ID, builder.build());
}
}
```
2. 在AndroidManifest.xml文件中声明Service组件:
```xml
<service android:name=".MyService"
android:enabled="true"
android:exported="false"/>
```
3. 在MainActivity中启动Service:
```java
Intent intent = new Intent(this, MyService.class);
startService(intent);
```
这样就可以在无activity应用中使用Service拦截广告通知,并在通知中显示正在运行的状态。通知的优先级设置为PRIORITY_MAX,用户无法将其销毁。
