Android的 - 在Android 4.1.1 Settings.ACTION_DEVICE_INFO_SETTINGS崩溃Android、ACTION_DEVICE_INFO_SETTINGS、

2023-09-12 04:50:19 作者：初心未变

我有一个应用程序，用户可以在我的应用程序点击某个按钮，它会推出具体的设置页面从Android的用户。我采用的是Android API从他们的网站 http://developer.android.com/reference /android/provider/Settings.html

I have an app where users can click on certain buttons in my app and it will launch specific settings page from Android to the user. I uses the android API from their website http://developer.android.com/reference/android/provider/Settings.html

Intent intent = new Intent(Settings.ACTION_SECURITY_SETTINGS);  
                    currentContext.startActivity(intent);

Intent intent = new Intent(Settings.ACTION_DISPLAY_SETTINGS);   
                    currentContext.startActivity(intent);

这些都是一些设置页面，我的应用程序将打开。到目前为止，我没有问题，从我的应用程序启动这两个意图。然而，当我尝试推出了关于平板电脑页面下方的code，设置进程崩溃。

These are some of the settings pages that my app will open. So far I have no problem launching these two intents from my app. However, when I try to launch the "About tablet" page with the code below, the Settings process crashes.

Intent intent = new Intent(Settings.ACTION_DEVICE_INFO_SETTINGS);   
                    currentContext.startActivity(intent);

据崩溃在Android 4.1.1，但它工作正常，在Android 3.2。我还是新的Android和我在为什么它崩溃丢失。我是新来的StackOverflow为好。希望我能在这里得到一些答案，很高兴见到大家。

It crashes on android 4.1.1 but it works fine on android 3.2. I'm still new to Android and I am at a lost on why it crashes. I'm new to StackOverflow as well. Hopefully I am able to get some answers here and nice to meet you all.

另外，我试图直接设置类名该API ...

Also, I tried to directly set the classname for this api...

Intent intent = new Intent();   
                    intent.setClassName("com.android.settings", "com.android.settings.Settings$DeviceInfoSettingsActivity");
                    currentContext.startActivity(intent);

同样的事情happens.It作品为Android 3.2，但在4.1.1不起作用。我已经得到了，也许我没有得到正确的类名4.1.1版本的感觉。有谁知道直接的类名称，打开关于平板电脑页面或是否有可能以编程方式打开该网页？

Same thing happens.It works for android 3.2 but doesn't work in 4.1.1. I've got a feeling that maybe I did not get the right class name for the 4.1.1 version. Does anyone know the direct class name to open the "About Tablet" page or whether is it possible to open that page programmatically?

问候，舒文

Android的 - 在Android 4.1.1 Settings.ACTION_DEVICE_INFO_SETTINGS崩溃Android、ACTION_DEVICE_INFO_SETTINGS、
