Change application s starting activity

Question

I have created the meat and guts of my application but I want to add a different activity that will be the starting point  sort of a log-in screen    Couple questions    1 I have a fairly decent handle on how to switch between activities  based on this article  http   www linux-mag com id 7498  but I m not sure how to go about creating a new one  with eclipse   2 Once I have a new activity created  how can I set it as the default activity of my application   I presume I could just change the name of the classes   but is there a more elegant way to handle that  maybe within the AndroidManifest xml

You add this you want to launch activity android:exported="true" in manifest file like

 <activity
      android:name=".activities.activity.MainActivity"
      android:windowSoftInputMode="adjustPan"
      android:exported="true"/>
  <activity

Open java file of this activity and right click then click on Run 'main Activity'

OR

Open java file of this activity and press Ctrl+Shift+F10.

Yes  you use the AndroidManifest xml file  You can actually even have more than one launcher activity specified in your application manifest  To make an activity seen on the launcher you add these attributes to your activity in the manifest    lt intent-filter gt       lt action android name  android intent action MAIN    gt       lt category android name  android intent category LAUNCHER    gt   lt  intent-filter gt

In a recent project I changed the default activity in AndroidManifest xml with    lt activity android name   MyAppRuntimePermissions  gt   lt  activity gt    lt activity android name   MyAppDisplay  gt       lt intent-filter gt           lt action android name  android intent activity MAIN    gt           lt category android name  android intent category LAUNCHER    gt       lt  intent-filter gt   lt  activity gt    In Android Studio 3 6  this seems to broken   I ve used this technique in example applications  but when I use it in this real-world application it falls flat   The IDE once again reports      Error running app  Default activity not found    The IDE still showed a configuration error in the  run app  space in the toolbar  yellow arrow in this screenshot     To correct this error I ve tried several rebuilds of the project  and finally File     Invalidate Cache Restart    This did not help   To run the application I had to  Edit Configurations  and point at the specific activity instead of the default activity

Just go to your AndroidManifest xml file and add like below    lt intent-filter gt       lt action android name  android intent action MAIN    gt       lt category android name  android intent category LAUNCHER    gt   lt  intent-filter gt    then save and run your android project

This is easy to fix     Changes to the Launcher activity are also stored in the Debug configuration   Go to Run  gt  Debug Configurations and edit the setting   There is also a similar setting in Intellij under Run  gt  Edit Configurations select Run default Activity and it will no longer save the setting in this fashion

If you are using Android Studio and you might have previously selected another Activity to launch    Click on Run  gt  Edit configuration and then make sure that Launch default Activity is selected

Go to AndroidManifest xml in the root folder of your project and change the Activity name which you want to execute first    Example     lt activity android name   put your started activity name here            android label   string app name  gt       lt intent-filter gt           lt action android name  android intent action MAIN    gt           lt category android name  android intent category LAUNCHER    gt       lt  intent-filter gt   lt  activity gt
