解决 java.lang.SecurityException: Media projections require a foreground service of type ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION

我在Android8.0上增加的截屏功能，也声明了响应权限，但是在Android11上就报权限错误。原来在Android10以后启动前台服务时候有第三个参数。

低版本我们调用
 public final void startForeground(int id, Notification notification) 即可

但是在Android10以后需要调用
public final void startForeground(int id, @NonNull Notification notification,
            @RequiresPermission @ForegroundServiceType int foregroundServiceType)

有个权限类型的参数。

解决方案：

 MediaProjectionManager mediaProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
             mediaProjection = mediaProjectionManager.getMediaProjection(intent.getIntExtra("resultCode", -1), intent.getParcelableExtra("data"));
             // 创建通知
             NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
                   .setContentTitle("Media Projection Service")
                   .setContentText("Running media projection...")
                   .setSmallIcon(android.R.drawable.ic_media_play);
             // 将服务设置为前台服务
             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                 startForeground(NOTIFICATION_ID, builder.build(), ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION);
             } else {
                 startForeground(NOTIFICATION_ID, builder.build());
             }
