如何启动Android应用程序管理器

Question

有谁知道android上应用程序管理器的包名称。我有一个方法，我想允许用户直接从我的应用程序转到应用程序管理器：

 public void goToApplicationManager(){
        Intent startMain = this.getPackageManager().getLaunchIntentForPackage("com.android.settings.ManageApplications");

        startActivity(startMain);
    }

但这会引发错误..我可以执行 com.android.settings，它会将用户带到设置，但我想将它们专门带到应用程序管理器。我的包名有错吗？

我的错误：

Answer 1

startActivity(
 new Intent(android.provider.Settings.ACTION_APPLICATION_SETTINGS), 0);

Answer 2

您查看过 ACTION_MANAGE_APPLICATIONS_SETTINGS 或 ACTION_MANAGE_ALL_APPLICATIONS_SETTINGS 吗？

Answer 3

尝试在清单中添加下一个权限：“android.permission.QUERY_ALL_PACKAGES”
