Android :: Improve Existing Applications?
Aug 18, 2009
How do I get (for example) the Android Calendar app into Eclipse so I can modify it and send in patches?
There's a ton of documentation on how to create *new* apps, but so far I've been unable to find any info on how to get *existing* apps into Eclipse. And my own attempts have gone so-so.
A good place for this information would be the developer FAQ for example: http://developer.android.com/guide/appendix/faq/commontasks.html

I don't know what to do. I have tried clearing the cache of the market, and the apps that are affected with updating. I can't use a backup utility, because well, if I try to restore anytime recently, the same issue exists. I am completely confused as to what made this happen and how to fix it. I would rather not wipe the phone to factory defaults.

With my location listener i get accuracy values about 30-100 m (being on an open field without annoying houses around me disturbing the gps signal). Why is that so bad? I thought you could get an accuracy about 3m with gps. And the Google maps applet for example has a much better accuracy. How can i improve the accuracy? I'm using the default gps provider. I saw you can create a Criteria object to get the best provider, but there are only the gps and the mobile phone net providers anyway - so it's some kind of senseless to get the location provider that way. is there no way to define the needed accuracy?

I'm faced to a big issue : I can't add datas to an existing contact I'm developing an application which manage contacts, I can add, delete or edit contacts. The creation is ok, because I create all types of datas (even if they are empty) for the contact (this is NOT a good way, I will change this later). So when I want to edit those datas I can find them to the data base (with Datas.CONTENT_URI) 'cause they already exist ! But if I create a new contact with the ANDROID contact application only the fill fatas are created for a contact. When I try to add new phone number for example with my application I get a error Here is my code to try to add phone number. Code...

I have an existing SQLite database file from another project.
Where do I include the database file into my Eclipse project to have it deploy with the app.
Do I need to indicate that the database file is writable? (In the iPhone world you need to copy the database file from the app's bundle to a writable folder on the iPhone proper before first use.)
Once I have the database file on the phone, how do I tell SQLiteOpenHelper to use it? (I extend SQLiteOpenHelper in a custom class.

I would like to create a user interface which would contain network indication icons (3G, WiFi...) and I would like to use existing graphic elements which are displayed in notification bar.
Does anyone know how to get these existing elements and use it in custom layout?
I guess these icons are all ImageView elements and I am wondering whether it is possible to retrieve them with findViewById() method...

Currently, attempting to scroll when the text view has large amount of text makes the app completely unresponsive. It doesn't ANR, but it doesn't respond either. I've tried occasionally removing some text from the text view and removing some spans also, but it doesn't seem to help much. Any idea how to improve scrolling? It takes ages to scroll up or down. I also tried throttling touch events but it hasn't helped either.

I've been trying VBOs (3D) and I've seen no improvement at all on my Motorola Dext over not using VBOs.I've tried all kinds of configurations, interleaved arrays, by t buffers instead of float buffers, both direct and indirect. My question is, has anybody got any measured improvement in frames per second by using VBOs instead of exactly the same content without VBOs? If and only if so, what were your fps results? And can you therefore show me the "proper" way of doing VBOs instead of not? Has anybody else got exactly the same fps with and without VBOs?

While I think the Google Mail app is ALRIGHT I think it needs quite some improvement so I am wondering if there is either a good alternative to it or if someone added features to it / modded it.
1)problem: i can't select any text from any emails (written by others or myself) which isn't too great when writing emails. is there any app for selecting text maybe? it's something i miss a lot on android. if i want to select text on a website I need to switch to Skyfire.I just can't believe coding a text selection is really hard so I don't understand why google didn't add it themselves yet.
2) problem: when I'm on the go and sending an email and the CONNECTION dies for a moment the Google Mail app will be stuck at "Sending..."I guess it is stuck in a loop then and it won't send out my email but I also can't go back so I can only close Google Mail with a task manager. Can't this be fixed, too? I just want a GO BACK feature so that it won't get stuck in a loop. Maybe just an automatic Save Draft just when someone clicks Send and then goes to the Send process and then you get the option to force close that and just go back- I dont know.

I read on many other topics that the Android emulator starts really slow. Indeed, it takes +15 mins to start. However, on my machine is slow even after that.The 'phone' responds with a 3-4 seconds delay and everything has a huge lag.Is there any way to improve the performance of my laptop (Asus 1201N) is too rusty for the Android emulator? Tried in different emulator resolutions and the result is the same.My laptop has 2 cores with HyperThreading. And it shows as 4 CPU in Device Manager. However, when using the emulator, just one of the graphs is at 100%. Can I do something to make it work multi core?

I'm getting started with Android development, but the emulator performance on my machine leaves much to be desired. In all fairness, my machine is not a powerhouse by any stretch of the imagination.
Short of upgrading my hardware or spending $$$, are there any good tips for improving Android emulator performance?

I have a droid and the range I get with wifi compared to a laptop is horrible. The networks I have tested on are all 802.11g. Is this just normal because of the antenna size on the droid or is there something I can do to improve it? I feel like I have to be right next to the access point to have a good connection.

I'm trying to add a phone number to an existing contact on android 2.1. Im currently using:
ContentValues values = new ContentValues();
values.put(Phone.RAW_CONTACT_ID,cursor.getColumnIndex(Phone.CONTACT_ID));
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,null, selection, null,ContactsContract.Contacts.DISPLAY_NAME+" COLLATE LOCALIZED ASC");
if (cursor.getCount() > 0) {cursor.moveToPosition(oldcontactid);
contactid = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
values.put(Phone.RAW_CONTACT_ID,cursor.getColumnIndex(Phone.CONTACT_ID));
if (Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{contactid}, null);while (pCur.moveToNext()) {values.put(Phone.NUMBER,pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
values.put(Phone.TYPE, Phone.TYPE_MOBILE);}pCur.close();}}
Uri uri = getContentResolver().insert(Phone.CONTENT_URI, values);
but i get an error:

Is it possible to add or change the existing applications?
For example, I would like to add a new floating window following the current people when I open the contact manager.
I just want to change it a little bit. And I don't want to rewrite all the features of contact manager.
Is it possible to do this?
As I understanding, the view of the contact manager is controlled by the activities of the "contact manager" application. How can my application react when the user opening the contact manager?
