Android :: Android Override Explicit Intent
Mar 7, 2009
My app needs to have a intent-filter that responds to a intent that has it's component set (a explicit intent.) Here is a example.
Intent i = new Intent();
i.setClassName("com.compareeverywhere","com.compareeverywhere.ScanActivity");
startActivity(i);
Just a simple intent-filter will not do - because the intent is made for a specific component (activity,) it just launches that without looking for intents at all. Is there a way to do this?

I'm currently using this in preferences.xml: .......................
This allows to trigger a custom Activity when this specific preferences item is triggered. Copying from the documentation, I'm using an implicit intent, and it's working. But I'd solve a problem if I could use an explicit intent, that is writing the fully qualified class name of the target Activity. I didn't find documentation about this, so I don't know whether it's possible and how to do that.

Is it possible to receive an explicit intent with the component option set? Example: Starting activity: Intent { action=android.intent.action.VIEW data=http://example.org flags=0x10000000 comp={com.android.browser/com.android.browser.BrowserActivity}}
The reason why i want to this this is because i want receive this intent above, launch another browser than the default one, and drop the intent before it starts the default browser. In another words, i want to make another browser the default one.

Working with android I realized that implicit intents are good choice in most of cases due to their's flexibility. But what's about explicit intents? What are benefits of using them? What are common cases when it's a good practice to use them?

Was trying to call another application using an *explicit* intent, but am finding it does not seem possible. I do not wish to use implicit intents. To test it out, try calling the YouTube main activity.
Intent i = new Intent(); ComponentName cn = new ComponentName("com.google.android.youtube","com.google.android.youtube.HomeActivity.class"); i.setComponent(cn); startActivity(i);
I get this error:
08-29 00:54:26.598: ERROR/AndroidRuntime(7332): Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.google.android.youtube/ com.google.android.youtube.HomeActivity.class}; have you declared this activity in your AndroidManifest.xml? Does anyone know whether this is possible? (using explicit intents to call another application)

I have some code that starts another activity based on a menu item selection:
..........
I've spent quite a bit of time on this and am inclined to file a bug report at this point. I can see a reference to the allegedly missing class in the classes.dex file inside the APK and the code works properly in the emulator. I haven't been able to find anything like this, so if there is, an RTFM pointer will be humbly accepted.

The error I receive is, "android.content.ActivityNotFoundException: Unable to find explicit activity class {com.droidea.birthday/ EditBirthdayActivity}; have you declared this activity in your AndroidManifest.xml?"
The error seems simple enough, but I don't see a problem with the way I have identified this activity in my manifest file. I have also been unable to see any problems with the activity class itself..............

When I use a RelativeLayout with either fill_parent or wrap_content as height and an element which specifies: android:layout_alignParentBottom="true" it is ignored and it is aligned at the top. Setting the height of the RelativeLayout to an explicit value makes it work.

Is there any way to disable or override the car dock app? I want the application that I am writing to be able to launch when the device is placed into the car dock. I have created a BroadcastReceiver for my app but the standard car dock app displays, not my app. I know that my broadcast receiver is working because when I click the back button on the device from the car dock app it shows my app. How do I get it to not show the car dock app? There is no listing for the car dock app in the list of installed apps on the phone. The only solution I have found on the web is to root your phone and change the .apk file name. I can't expect my users to do that.

To develop an APK, I want to modify or expand ContactsProvider functionality. GoogleContactsProvider is my role model. But I can't put my code to Android repository, like GoogleContactsProvider does. Mine is a 3rd party APK to develop.
http://groups.google.com/group/android-developers/browse_thread/threa... was the idea.
Just curious how to make a customized provider for Android ContactsProvider.

I've made a little test component that overrides ImageView, called myImageView, and prints some text and an arrayList of Doubles over whatever image is specified in the related xml. However, right now, the text and Doubles that are drawn over the image are defined within the myImageView class. Is there a way to pass the data from the main onCreate function to the myImageView class before the layout is drawn?
I'm new to OO programming, but based on my understanding of this:
http://developer.android.com/guide/topics/ui/custom-components.html
It's possible because ImageView is just like any other class. This leaves me with two initial guesses:
1. I could generate my test data in the main onCreate, and store it in the array's xml file, and then read that xml file with myImageView,
OR
2. I could extend view instead of ImageView, but because of my new- ness, then I would lose the ability to use it in an xml layout sense - and that's what I really want.

I've got an AVD setup with an SD card, but I wanted to specify a different SD card image by setting a -sdcard option in Eclipse under Preferences -> Android -> Launch (I fill in "-sdcard C:sdcards sdcard96M.img" without the double quotes). But it seems no matter what I do, I always get the SD card that was created with the AVD. From the command line, the following works: emulator -avd myAVD -sdcard C:sdcardssdcard96M.img Do I need to use the command line instead of Eclipse to run this way?

I'm trying to change the content of a row in ListView programmatically. In one row there are 3 TextView and a ProgressBar. I want to animate the ProgressBar if the 'result' column of the current row is zero.
After reading some tutorials and docs, I came to the conclusion that LayoutInflater has to be used and getView() - overriden. Maybe I am wrong on this. code...

I have an ArrayAdapter wrapped around an ArrayList of custom objects. I'd like to write a custom filter for that adapter so that when I call getListAdapter().getFilter().filter("abc") the list will get filtered by an arbitrary transformation of "abc".
I thought I would just try to override ArrayAdapter.getFilter(), but that requires I re-implement the private ArrayAdapter.ArrayFilter which requires access to a bunch of ArrayAdapter's private instances.
What's the simplest way to do this?

I want to override the behaviour of the ENTER key of the virtual keyboard so that:
* when there are more fields on the screen, it 'tabs' to the next field.
* when it is the last field of the screen, it performs the default action of the screen
I've been playing with the IME options and labels, but just don't get what I want. Anybody a suggestion?
