Switch TargetActivity programatically


Switch TargetActivity programatically



I have an activity alias that leads to one of my activities.


<activity-alias
android:name="LauncherOne"
android:enabled="true"
android:targetActivity="org.test.app.LauncherActivity">

<intent-filter>
<action android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

</activity-alias>



I want to be able to choose which activity it goes to, so how can I change the targetActivity programatically?
I can't really find a workaround, because I cant enable/disable two different targetactivities as it would forget the default launcher every time.
And I haven't found a way to switch acitivities that doesn't cost some performance in my app.

You can't. That information is baked into the manifest and cannot be changed at runtime.



Workaround: Have one activity that is your launcher activity. Have that activity use Theme.Translucent.NoTitleBar as a theme, so it has no UI. Have that activity launch the "real" activity based on whatever criteria you choose, then finish() itself so that it is no longer in the back stack. Roughly speaking, this is the same approach that would be used by an app that had a splash screen activity that then decided what activity to go to next, just without the actual splash screen UI.


Theme.Translucent.NoTitleBar


finish()

How to input without newline? (Python)

How to input without newline? (Python) I am trying to create a simple file editor in Python via the console (called PyCons). Here is my current program: def PyCons(f): file = open(f, "r") appe = open(f, "a") print("n=====nPyCons Editor, v1.2nPython 3.6.1n") global i i = 0 for line in file: i += 1 print(" {}| ".format(i) + line, end='') for k in range(10000000000000): print("n {}| ".format(i+1), end='') inp = input("") if inp == "@PyCons.save()": print("n=====") break else: i += 1 appe.write("n" + inp) I used the end method to make sure that the existing code in the file was printed properly in its line format, but the input function does not have an end attribute. So, when I go to enter code in the editor: end input end PyCons("magic.html") ... ===== PyCons Editor, v1.2 Python 3.6.1 1| <p>Hello!...
