Does anyone know any guide to test android application on different hardware emulators and also step by step process to publish the application once it is developed and tested on a local emulator?
Hi,
I have an activity that uses VideoView and MediaController.
I have a .mp4 file.
(1) When I put the file in res/raw folder, I can play the video using Uri.parse("android.resource://<package>/" + R.raw.id_video)
(2) However, when I put the same file in the file-system, it plays properly.
I use videoView.setVideoPath("/sdcard/myfile.mp4");
What can be the problem?

I have a free app published in Android market. I have lost the certificate used to sign the current version but I want to publish an updated version. Android market refuses to accept my upgrade because it is signed by a new certificate. I realize the users will have to uninstall the current version to get the upgrade but it's not clear how to get the updated version into the market so that the current users will find it.
What are my options?
Thanks,
John

Hi all,
I want to go to a web page on the click of a button in my android app. So say, I have a button called "Google", when the user clicks on that button I want google.com to open up on the screen. How is this achieved?
Also, is there a way I can gain control back to my app once the user is finished with google?
Thanks

Does the calendar application in Android maintain a cache of its database?
Whenever I edit and mark some events via the calendar app, it is stored in the database but if I edit the calendar.db from some outside source the changes made are not reflected in the calendar app. So my question is:
Does the calendar app maintain a cache or some other form of database?
If yes then where and how?
I'm trying to write a program that needs smooth orientation sensor samples as the phone is rotated all around. Every time the orientation of the phone is changed, it interrupts the data and freezes the program while the layout changes. How can I lock it in one orientation (landscape or portrait, it doesn't matter)?
I assume it has something to do with android:layout in the xml file, but I can't find anything online.
In Android documentation concerning code signing we can read: "By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner."
How exactly such code sharing can be done? Is it possible to release main application and multiple exchangeable plugins then discover them at runtime? What does source code looks like and what are advantages over "standard" intents calls from/to different APK packages?
Lets say I have an Android app that uses Google Maps and GPS.Uses custom views and timers.
