I'm trying this: Start an activity by ADB. When the activity started, there'll be a form to input text, but my problem is that activity does not auto focus the text box, so i couldn't use "adb shell input text xxxxx".
So how can I make the activity auto focus the text to input? or can I call the keyboard activity and the text box will be auto focused? if yes, how?

I have an application with contains multiple activities. The main activity will start the others ( use startActivity() ) depends on user event, when an activity close, it calls finish() and return back to main activity. It appears to behavior like that.
However, the "problem" I see is main activity's onCreate function is called every time. I think the the main activity should be placed in the activity stack and simply push to front when others exit, therefore only onResume, onStart are called. Is there some flag I need to set or I misunderstand the activity behaviro?
In child activity, besides calling finish() or startActivity for main activity, what is other way to move main activity to front?
I created an application which enables the user to set whether he wants to receive notification while the application runs in background mode. If the notifications are enabled an activity should be started (the dialog should appear on the screen).
I tried to enabled it the following way:

This is the method from main activity. When onPause() is executed isRunningInBackground is set true.
When I tried to debug it when the main application was running in the background the line
startActivity(intent) had no effect (the activity didn't appear).
Does anyone know how to midify the logic in order to start an activity from the main activity when the main activity is running in the background (after onPause() is called)?
I have tried to write an Android application with an activity that should be launched from a different application. It is not a content provider, just an app with a gui that should not be listed among the installed applications. I have tried the code examples here and it seems to be quite easy to launch existing providers and so on, but I fail to figure out how to just write a "hidden" app and launch it from a different one.
The basic use case is:
App A is a normal apk launchable from the application list.
App B is a different apk with known package and activity names, but is is not visible or launchable from the application list.
App A launches app B using the package and class names (or perhaps a URI constructed from these?).
I fail in the third step. Is it possible to do this?
I need to made an activity (without layout) that on start check if a service is running. if it is true it starts Activity2, if it false it starts Activity1.

I have a huge maze of activities in my application. What I need to do, is that when the user logs in into the system, the activity history should be cleared. I cant just use finish() when I start a new activity, because I want the activities to have a history until the user logs in. I have experimentet with the different flags when starting an activity, but I have had no success.

Is the Evo supposed to be auto-focusing when its recording video? If I have just the viewfinder and no recording going on, it auto-focuses whatever I point it at, but when it comes to recording, its not auto-focusing at all. It just stays blurry.

I have created two classes: Example1 and Example2, which extends activity.
Example1 contains a UI of buttons, while Example2 contains UI of TextEdit.

Intent i = new Intent();
i.setClassName("com.a.ui", "com.a.ui.Example2");
startActivity(i);
So I am able to get the UI of Example2 successfully.
What's an alternate way of calling intent?

View 1 Replies View RelatedI have 2 activity...suppose i name it activity A and activity B.When the application starts it shows activity A.Then after 5 seconds,it automatically switch to activity B.Activity B contains a listview and checkboxes with each item of listview.If user checks something then he press back button and returns to activity 1 page.All these works correctly.
Now my problem is,activity A has a button to go again activity B page.When user press this button i want to start activity B from where it stops..that means the user will see what items he had checked earlier.Is it possible to view the activity B page from where it stops?

Well I had no luck in the other thread, but is the Evo supposed to be auto-focusing when video recording? When It's not recording, it auto-focuses on anything I'll point it at just fine, then when I hit record, and happen to move, it stays blurry and doesn't auto-focus.

I get the exception ERROR/AndroidRuntime(2500): Caused by: android.view.WindowManager $BadTokenException: Unable to add window -- token null is not valid; is your activity running?
At the moment I am calling from onCreate, but when calling from onStart or onResume it still gives the same error.
The activity api says the activity is supposed to be running after onResume is called. Where is the best place to load up the PopupWindow if it needs to be done straight away?
At the moment It looks like Activity.onWindowFocusChanged() is the best place.
