blocks|key|851343|text|在Android2.3中，你可以通过一个合适的Uri在ACTION_APPLICATION_DETAILS_SETTINGS+Intent上使用startActivity()来打开你的应用程序的“管理”屏幕。然而，这是Android+2.3的新特性--在以前的Android版本中，我不知道有一种方法可以做到这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|851344|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/provider/Settings.html#ACTION_APPLICATION_DETAILS_SETTINGS^0|N|3|R|Z|1R|6|20|F|R|Z|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@$9|W|A|X|1|Y]]|E|$]]|$1|F|3|-4|5|6|7|Z|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

In Android 2.3, you can use <code>startActivity()</code> on an <a href="http://developer.android.com/reference/android/provider/Settings.html#ACTION_APPLICATION_DETAILS_SETTINGS" rel="noreferrer"><code>ACTION_APPLICATION_DETAILS_SETTINGS</code></a> <code>Intent</code>, with a proper <code>Uri</code>, to bring up your app's "manage" screen. However, this is new to Android 2.3 -- I am not aware of a way to do that in previous versions of Android.

<pre><code>startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_SETTINGS));
</code></pre>

will bring you to the settings / application list.
If you want to open one specific application, I think in 2.2 and below there's no way, so you'd need to go a (not necessarily suggested, because inofficial) way:

<pre><code>final Intent i = new Intent("android.intent.action.VIEW"); 
i.setComponent(new ComponentName("com.android.settings","com.android.settings.InstalledAppDetails"));
i.putExtra(...); // need to figure out the correct extra, probably app package name
startActivity(i);
</code></pre>

But note that this is not recommended because it's not an official API / intent (filter) and might therefore change in the future.

I used Paolo solution in order to open the Application Details Settings in SDK 23+ when the user turned down the permission request in the past and choose the "Don't ask again" option in the permission request system dialog.

But in this case I used the <code>getPackageName()</code> method directly.

<pre><code>Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:" + getPackageName()));
startActivity(intent);
</code></pre>

Is it possible to start the "application info" screen (that is, <code>Menu</code> &rarr; <code>Settings</code> &rarr; <code>Applications</code> &rarr; <code>Manage Applications</code> &rarr; select any application) from another app?

How can I start android application info screen programmatically?

Android

是否可以从另一个应用程序启动“应用程序信息”屏幕(即Menu Settings Applications Manage Applications→选择任何应用程序)？
