how to start an activity defined in java library

[fenoglio]

hello everyone,

my basic4android app has to start an activity defined in java library.

i've built a java library and sucessfully imported in basic4android. The library contains just a public class that extends android.app.Activity.

@ShortName("DemoLibActivity")
public class DemoLibActivity extends Activity {
...

i need to use this libray in my basic4android app and i need to perform a startActivityForResult. for instance, i'm able to use the library in other java class like as

public class MainAppActivity extends Activity {
...
final Context ctx = getBaseContext();
Intent intent = new Intent(ctx, DemoLibActivity.class);
startActivityForResult(intent,requestCode);
...

but i don't know how to translate these three lines in b4a.

any solutions?

regards

You should declare this activity in the manifest file.

See this link for more info on startActivityForResult: http://www.b4x.com/forum/libraries-developers-questions/7297-guide-using-onactivityresult.html

do you mean put an AndroidManifest.xml in java library that contains the activity that is called by b4a app?
ok but, how i can perform the startActivityForResult on this activity from b4a app?

in summary, i've an existing b4a app and from here i want call an activity located in a external library; this activity shows a login form, then performs a request to protected web services and then returns the response for b4a app. I've tried to simulate the behavior of b4a app building a mockup in java and the startActivityForResult works fine as defined in my first post; in that case the called activity is defined in AndroidManifest.xml located in java mockup.

thank for the support.

Are you talking about two separate app's
then calling one with an intent

or all within one app?

i'm working on the same problem

 

[fenoglio]

all within one app. this app is built using b4a. this app imports a java library that contains just an activity, a class that extends android.app.Activity. i need or would to perform a startActivityForResult, in b4a code, on this activity.

No. You should add the declaration to the manifest editor in the B4A project.

You cannot call startActivityForResult directly from B4A. The library should call it as described in the link I posted.

i only use *.jar file,with out xml file.how can i use this activity?
public class SplashSpotActivity extends Activity {

i use this to load the jar:#AdditionalJar: YoumiSdk

This is an old thread. You should have started a new one instead.

You need to add the activity declaration to the manifest editor and then create an intent that starts this activity. Check the documentation that comes with the SDK. It will usually include those parts (in Java).
