Develop Reference

Running empty Android program - is this behavior expected?

I'm learning the basics of Android development and I've ran into some issues with setting up the programming environment. Now I've created a new Android Application Project and I'm running it using my phone. When I do, I get an error message on my phone: "Unfortunately, HelloWorld has stopped." and I'm not sure if it's supposed to or not, considering that I've done absolutely nothing to the project files. Here is the LogCat output in its entirety:

So, is this normal behavior or have I done something wrong while setting up Eclipse, etc?

It looks like the Android compatibility library is not correctly configured for your project. In Eclipse, right click on the project in the package explorer and select Android Tools > Add Support Library. After setting up the support library, clean and rebuild your project.

This is normal behavior when reporting an error with your application.

How open native call details screen for a particular call log in Samsung and HTC android device using intent?

I am developing an android application to show all call logs in the list and when user taps on any call log, i need to open native app's call details screen for that tapped call log.
I have tried following code snippet and it works fine in Emulator (Pure android OS.)
Intent mDetailsIntent = new Intent(Intent.ACTION_VIEW); mDetailsIntent.setType(android.provider.CallLog.Calls.CONTENT_TYPE);
Uri mUri = Uri.withAppendedPath(android.provider.CallLog.Calls.CONTENT_URI, String.valueOf(mCallLog.getId()));
mDetailsIntent.setData(mUri);
startActivity(mDetailsIntent);
But when I run it on Samsung device, it shown the last recent call log's details screen each time regardless of call log id.
And for HTC devices, it throws ActivityNotFoundException.
Following log cat is for HTC device.

Have you given the permission to read the local storage? You should check if any permission is declared in Android Manifest regarding Writing and reading of Internal Storage.

did you add permissions
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
One more thing:
With sdk, you can't write to the root of internal storage. This cause your error.Try something like this
final File dir = new File(context.getFilesDir() + "/nfs/guille/groce/users/nicholsk/workspace3/SQLTest");
dir.mkdirs(); //create folders where write files
final File file = new File(dir, "BlockForTest.txt");

any help is appreciated

You're doing network stuff on the main thread. Don't do that. Use AsyncTasks instead.
