Difference Between 2 Ways To Start An Activity


I have seen the following two examples of starting activities in android:

Example 1

Code:.

Example 2

Code:.

It seems the obvious difference between the two examples is that you attach the logic of how an activity is created to the implementation of the activity. Are there any other key differences? (e.g. Is the calling activity told to wait until the called activity finishes in one case, but not in the other, etc. )

Activity Lifecycle Difference Between Device And Emulator

I recently noticed there is a difference in behavior between an actual device (htc magic in my case) and the emulator. What i noticed is that in the device when another activity is started via startactivity(), the calling activity does not get destroyed. In the emulator, the calling activity is paused, and right after the new activity is resumed, the calling activity is destroyed.

Does anyone know if these behaviors can exist in any device or the emulator behavior is local to it? I thought the emulator is supposed to behave like an actual device since the codebase are the same? Btw, both are using adroid 1. 5.

If this topic is already present in the discussions, sorry for the duplicate and kindly point me to the right direction.

Activity Will Not Start After Action_screen_on Is Received

I am creating a lock replacement application which obviously requires it to have an activity that starts the action_screen_on is called.

These are the portions of my code relevant to it:

Code:.

Since action_screen_on cannot be called from the manifest i registered it dynamically in my main activity.

This is in my oncreate function of my main class (lockdown)

Code:.

Force Destruction Of Old Activity And Start A New One With Parameters

I have a service that starts an activity on certain event passing to it some parameters.

The problem is if the activity is still open, when the service tries to startactivity() again, the activity isn't started because it's already started.

Is there a way to force the destruction of the old activity and start a new one with the new parameters?

Sony Ericsson Xperia X10 - Syncing Contacts - Does It Work Both Ways?

I have made a few changes to my contacts' details over the last couple of days, both online and on my phone (x10a). If i sync the contacts, will the online stuff over-ride the changes i've made in the phone, or will the phone take priority?  I'd like it to give me a choice of which changes to keep. If it uses the details i have most recently changed, that would be ideal, but i don't really want to try it until i know what will happen.

Htc Hero - Mms Message Crashed My Phone / More Effective Ways To Handle It

After using my hero for a bit over a month, i've had my first run in with a serious problem. I received a mms text message, and every time i tried viewing the messages page (using the default messaging program) for that contact, i would get a force close error for com.android. Mms.

After trying a few more times, rebooting the phone, etc, i decided to try handcent sms. Fortunately, handcent did not crash when i viewed that contacts messages, but it also couldn't read the message stating something like "handcent sms is unable to read this message. " Oddly though, i was able to use the save mms option not only to see the image, but successfully save it as well. I was happy about this, but when i tried to delete the message so that i could continue to use the default messaging program (i like the widget, sorry), it could not delete the message.

The only way i could rectify the problem was by deleting the entire messaging thread with that contact.

Now, this has only happened once so far, and i have yet to try to reproduce it; nonetheless, it's a pressing issue i'd like more information on. Has anyone else had this happen? Are there any more effective ways to handle it other than deleting the entire contact thread?

Difference Between Invalidate() And Postinvalidate()

What is the difference between invalidate() and postinvalidate(), except the obvious (i know that postinvalidate post an invalidate- request on the ui-thread, while a call to invalidate() invalidates the view immediately). I've done a viewgroup with some scrolling- animations, and to redraw the view from computescroll(), i needed to call postinvalidate(), the regular invalidate() does not redraw the screen. This is how it's done in scrollview too, so why isn't the screen redrawn when i call invalidate() from computescroll?
