我怎样才能启动Android应用程序信息屏幕编程？ [英] How can I start android application info screen programmatically?

问题描述

是否有可能启动应用程序信息屏幕（即菜单＆RARR; 设置＆RARR; 应用程序＆RARR; 管理​​应用程序＆RARR;然后从另一个应用程序的任何应用程序）

Is it possible to start the "application info" screen (that is, Menu → Settings → Applications → Manage Applications → select any application) from another app?

推荐答案

在2.2及以下，没有公开的API可以访问。但是，你仍然可以启动 InstalledAppDetails 活动就像 ManageApplications 一样。看<一href="http://android.git.kernel.org/?p=platform/packages/apps/Settings.git;a=blob;f=src/com/android/settings/ManageApplications.java;h=9cd6e23ce3a0fb2254fdaa2ebde3a7fc9324d4e6;hb=c0a606d2d639c34bb763b73974e04e55f2d2ad8d">here

In 2.2 and below, there is no public APIs you can access. But you can still start the InstalledAppDetails activity just as the ManageApplications does. see here

 // utility method used to start sub activity
 private void startApplicationDetailsActivity() {
     // Create intent to start new activity
     Intent intent = new Intent(Intent.ACTION_VIEW);
     intent.setClass(this, InstalledAppDetails.class);
     intent.putExtra(APP_PKG_NAME, mCurrentPkgName);
     // start new activity to display extended information
     startActivityForResult(intent, INSTALLED_APP_DETAILS);
 }

结论：您可以启动应用程序信息屏幕这样的我写的：

Conclusion: you can start the "application info" screen like this i wrote:

private static final String SCHEME = "package";

private static final String APP_PKG_NAME_21 = "com.android.settings.ApplicationPkgName";

private static final String APP_PKG_NAME_22 = "pkg";

private static final String APP_DETAILS_PACKAGE_NAME = "com.android.settings";

private static final String APP_DETAILS_CLASS_NAME = "com.android.settings.InstalledAppDetails";

public static void showInstalledAppDetails(Context context, String packageName) {
    Intent intent = new Intent();
    final int apiLevel = Build.VERSION.SDK_INT;
    if (apiLevel >= 9) { // above 2.3
        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        Uri uri = Uri.fromParts(SCHEME, packageName, null);
        intent.setData(uri);
    } else { // below 2.3
        final String appPkgName = (apiLevel == 8 ? APP_PKG_NAME_22
                : APP_PKG_NAME_21);
        intent.setAction(Intent.ACTION_VIEW);
        intent.setClassName(APP_DETAILS_PACKAGE_NAME,
                APP_DETAILS_CLASS_NAME);
        intent.putExtra(appPkgName, packageName);
    }
    context.startActivity(intent);
}
