权限拒绝：起始意图（锁定任务模式 /信息亭模式）

Question

有人有建议如何解决此错误？ 我正在尝试使用Intent getlaunchintentforpackage 运行锁定任务，但是我不知道为什么会出现此错误以及它想要运行此任务的哪种许可。

java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 pkg=com.example.videoplayer cmp=com.example.videoplayer/.MainActivity } from ProcessRecord{fd194a9 7523:com.example.lock/u0a190} (pid=7523, uid=10190) with lockTaskMode=true

我目前遇到相同的错误。我唯一可以向您交给您的是，可以使用Android网站上所述的DevicePolicyManager.setlocktaskPackages来解决它： https://developer.android.com/work/dpc/dedicated-devices/lock-task-mode#allowlist_apps
