Want to get back to last Activity after pressing Launcher Icon for my app

懵懂的女人 提交于 2019-12-07 14:31:59
问题 Suppose I have an activity A that starts activity B and kills itself. Now I press the Home button (or leave the app some other way) (causing onPause->onStop for activity B) and I click the app icon in the launcher again. What happens is that activity A is started again (of course because I specified that intent-filter in the manifest XML). Is there an easy way to just get back to activity B without starting activity A again? I basically want to get to onStart->onResume in activity B when I

Using relative paths for Gnome launcher

自作多情 提交于 2019-12-07 14:20:08
问题 We're developing an app that needs to run on a removable device (e.g. USB stick). On Linux, we're using Gnome launchers to place a shortcut to the app on the root of the device. However, we need to use relative paths for the executable and icon since we don't know in advance where the device will mount. In the .desktop file I have something like: Exec=../myapp/myexecutable Icon=../myapp/myicon.png Neither the executable or icon is found. I read the spec on icon lookup in .desktop files (http:

Android Application creating two launcher icons

你说的曾经没有我的故事 提交于 2019-12-07 01:07:24
问题 I am having a very confusing problem with an application I have been working on for some time. Suddenly, when running my application, I found an immediate force close upon launch. Upon further investigation, I found two launcher icons in my launcher. One of which will either resume the application if it is running or force close if it is not running. The second will behave as normal - launches the application normally and resumes normally. I am very confused, as I was not doing anything (that

问题 I have developed an edge browser extension (native messaging) using the in-process mechanism as described here (through an activation of OnBackgroundActivated ). Within OnBackgroundActivated , or to be more specific in OnAppServiceRequestReceived of the established app service connection, I am attempting to call Windows.System.Launcher.LaunchFileAsync(IStorageFile) . This doesn't appear to happen on the UI-Thread (although it does work in debug mode with a debugger attached). The problem that

前言: 各位小伙伴,又到了每周更新文章了时候了,本来是周日能发出来呢,这不是赶上清明节吗,女王大人发话了,清明节前两天半陪她玩,只留给我周一下午半天时间写博客 ,哪里有女王哪里就有压迫呀有木有!好了闲话少说,上一篇博客( Android Metro风格的Launcher开发系列第二篇 )说到Launcher主体框架用ViewPager来实现,这一篇博客咱们来说说每一个page的具体实现。 PagerAdapter: Launcher主体ViewPager实现就引出了PagerAdapter,PagerAdapter是android.support.v4包中的类,它的子类有FragmentPagerAdapter, FragmentStatePagerAdapter,这两个adapter都是Fragment的适配器,这里因为没有用到Fragment所以这里不讲,我只讲PagerAdapter。关于PageAapter的描述,Google官网原文是这样的:Base class providing the adapter to populate pages inside of a ViewPager. You will most likely want to use a more specific implementation of this, such as

how to keep my Launcher out of being kill by OS?

空扰寡人 提交于 2019-12-06 12:32:57
I am working on a project of 3rd-party Android Launcher. I find it being killed often by OS when running in background, even it is the default Launcher. OS will kill many apps when available memory is not enough, I guest that the reason why my Launcher is killed. So my question is what should I do to decrease the chance of being killed ? Nothing. You should find a way to handle the event where the OS kills your process, using a hacky approach to keep it in memory is bad, bad design and could lead to all sorts of issues on different devices. You really shouldn't even care that the system is
