java - Intent 无法从应用程序内获得

Question

我有 Intent com.amazon.tv.settings/.hud.HudActivity，我可以使用adb shell am start -n "com.amazon.tv.settings通过adb启动它Amazon Fire TV v3 上的/.hud.HudActivity”。但是，当我通过代码启动相同的 Intent 时:

getApplicationContext().startActivity(new Intent("com.amazon.tv.settings/.hud.HudActivity"));

无法找到产生错误的 Activity :

E/AndroidRuntime: FATAL EXCEPTION: Timer-0
                  Process: com.baronkiko.launcherhijack, PID: 23262
                  android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.amazon.tv.settings/.hud.HudActivity }

                      at java.util.TimerThread.run(Timer.java:505)

这是我真正需要的系统 Intent 。我如何启动这个 Intent ，我需要更多权限吗？我感谢我可能收到的任何帮助。

请尝试这个:

    Intent intent=new Intent();
    intent.setComponent(new ComponentName("com.amazon.tv.settings", "com.amazon.tv.settings.hud.HudActivity"));
    getApplicationContext().startActivity(intent);

当你打电话时

new Intent("com.amazon.tv.settings/.hud.HudActivity")

“com.amazon.tv.settings/.hud.HudActivity”被视为操作而不是类名称。
