Android Q特性之后台启动Activity限制

从Android Q版本开始，google为了让用户有更好的使用体验，限制后台App启动Activity，以防止打扰当前用户操作。

对于即时通讯、需要用户马上应答等场景，如视频、音频Call，google给出的建议是使用Full Screen Intent Notification。代码如下：

String title ="Title";

String content ="Content";

Intent fullScreenIntent =new Intent(this, MainActivity.class);

fullScreenIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

fullScreenIntent.putExtra("action", "action");

PendingIntent fullScreenPendingIntent = PendingIntent.getActivity(this, 0, fullScreenIntent, PendingIntent.FLAG_UPDATE_CURRENT);

NotificationCompat.Builder notificationBuilder =

new NotificationCompat.Builder(this, id)

.setSmallIcon(R.mipmap.ic_launcher)

.setContentTitle(title)

.setTicker(content)

.setContentText(content)

.setAutoCancel(true)

.setDefaults(Notification.DEFAULT_ALL)

.setPriority(NotificationCompat.PRIORITY_MAX)

.setCategory(Notification.CATEGORY_CALL)

.setFullScreenIntent(fullScreenPendingIntent, true);

notificationBuilder.build();
