在释放模式下按下Home键后,loginActivity重新打开

我的问题是,如果我在应用程序中打开任何活动,然后按主键按钮。然后重新打开应用程序,则会打开登录活动,而不是打开用户实际在其中的当前活动。

这仅在发布模式下发生。

如果我以调试或发布模式从android studio中运行该应用程序,则它可以正常运行

只有在我生成发行版APK时才会发生

有什么想法吗?

2 个答案:

答案 0 :(得分:0)

如果您只想打开一次登录活动,并且在登录并重新打开应用程序时要打开家庭活动,则只需保存应用程序状态或将登录状态保存在共享首选项中即可。比较启动时的情况,然后决定应该在哪里进行首页活动或登录活动。

在登录活动中调用登录功能后获得成功时,请执行以下操作:

 SharedPreferences pref = this.getSharedPreferences ("Login",0);
 Editor editor = pref.Editor();
 editor.putBoolean("login",true)
 editor.commit();

在启动屏幕代码中执行此操作:

Boolean loggedIn = SplashScreen.this.getSharedPreferences("Login",0) .getBoolean 
                   ("login",false);
if(loggedIn) {
startActivity(new Intent(SplashScreen.this,HomeActivity.class));
finish();
} else {
startActivity(new Intent(SplashScreen.this,LoginActivity.class));
finish();
}

当您按下主屏幕按钮时,您的应用程序将进入后台状态。在这种状态下,您的应用可能会被操作系统杀死,也可能不会被操作系统杀死(官方资料进行了详细说明)。您应该假设它总是如此。在这种情况下,当您导航回您的应用程序时,您的应用程序将表现为首次运行。

为解决这个问题,一种常见的方法是创建一个“控制器”活动(称为Splash)并将其设置为启动器。该活动包含决策代码,可将用户导航到适当的活动。
