I found a post from a while ago that addresses a similar question but I think it's a bit outdated. I realize implementations of JPA tend to be more on the heavy/dense side, so if you know of any lightweight (non-JPA) ORMs I'll most certainly appreciate your input. I did see the answer about ActiveAndroid in the other post and am curious to know if anyone tried it out.

I want to know why SQLite doesn't support encryption! & How to secure the SQlite db on a Android app?
View 3 Replies View Related1. Is there any stored procedure support in the sqlite database of Android? and any docs on doing this?
2. Is there any way my Android progam can know the data in the Android native data set have been changed? like contacts, calllog, and calendar? that is, once the data inside the Android native database have been changed, can my program be notified? and how to do it?
I have a .jar in my Android project which has many references and uses of the java.awt.* classes and other classes not available on Android. How can I provide my own implementations of these classes so that I can embed the unmodified .jar file (the only modification is being ran through dx) in my Android application and it will use my own class implementations?

View 2 Replies View RelatedI have been building all my apps against the 1.6 version of the SDK until just recently when I switched to 2.2. I use ant to handle my builds and a normal build time for one of my apps was about 30 seconds. Now that I am building with 2.2 (that is the only change) it is taking over a minute to do the exact same thing... I was just wondering if anyone else was seeing a significant increase in the time it takes to build with 2.2.
When I make incremental changes to code in eclipse I am now noticing a "Building workspace: (xx%)" which takes a VERY long time in 2.2 compared to 1.6. I hardly every used to notice this because it was so fast. Now I notice it all the time.
I really hope that as we see additional sdk version come out that things just get slower and slower... also, I had read that with 2.2 we would see "significant" increases in performance on our existing hardware (devices). I'm definitely not.
I think the answer is going to be no, since the only question on the matter on SO is about memory requirement. However, before I go porting unrar to the android, I'd like to know if someone has done it already.

View 3 Replies View RelatedI have class A, with methods foo and bar, that are implemented by A1 and A2. The functionality in both A1 and A2 is the same. In other words:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} } class A2 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} }
Is it better to keep the code in this fashion, or to swap out those virtual methods as static methods? (In Java, everything non-final/non-private is considered virtual, right?) According to the Designing for Performance section in the Android Developer Docs, I should swap out these virtual methods for static ones. So the above becomes:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} class A2 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} }
Is this how it "ought" to be? I fully realize that I may be misinterpreting this paragraph in the docs.
I feel like this is such a stupid question but I can't find the answer anywhere else. How do I go about backing up my contacts prior to installing, e.g., the new ROM upgrade on the Hero? Presumably I would need to get the data actually off the phone on to my computer but I can't figure out how to, and I have too many contacts to save them all individually to my SIM card. I have been having major problems with HTC Sync (as long as it's installed on my computer it seems to knock out my wireless internet connection intermittently, which makes no sense, but I've uninstalled and reinstalled a couple of times and it's definitely HTC Sync doing it) so if there's a method that doesn't involve HTC Sync?

View 3 Replies View RelatedI'm trying to build a app that uses the SmsMessage class but there are two versions depending on the API level of the device:
android.telephony.gsm.SmsMessage (deprecated for 1.6 and above)
android.telephony.SmsMessage (the new class for 1.6 and up)
I want to target 1.5 and yet have the newer class (android.telephony.SmsMessage) run on devices with 1.6 or higher. How do I do this?
I have already tired this: http://devtcg.blogspot.com/2009/12/gracefully-supporting-multiple-android.html but I couldn't get it to work (the author doesn't mention how he/she handles the different imports, the exact api level settings etc.)

I want to create a table whose primary key will be some other field and not _id . The below table gets created but the value of _id remains null :
"create table accounts ("+BaseColumns._ID+" integer , profile_name text primary key" +" name text not null);";
My doubt is wont _id get auto incremented if we do not place "+BaseColumns._ID integer primary key autoincrement+" .
I'm new to Android, I just finished the Notepad Tutorials, where we can create SQLite Databases to save notes. So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.
View 9 Replies View RelatedI read in the documentation for SQLite that there should be some core functions and aggregate functions available, but I can't seem to use them in my code.. Can anyone help? Here's the documentation ad: http://www.sqlite.org/lang_aggfunc.html http://www.sqlite.org/lang_corefunc.html There is for example the function count() but how do I use it? I have tried to use it as stated below, but none of the functions in the documentation is available that way (i.e when I type "db." the list that shows in Eclipse documentation doesn't include any of the functions from the SQLite doc except from execSQL):

I'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?
View 3 Replies View RelatedI put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?
View 3 Replies View RelatedI have a SQLite database, and several tables within that datbase. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1).
I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch.
The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well.
Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.
Firstly, I have found many examples of how to grab data from a db and place it into a list, however this seems to be all for ListActivites.
My list is part of the UI and therefore I can't use a ListActivity because it does not consume the whole screen (or can I?).
This is the UI:
CODE:........
So, from what ive read I need to grab the data from the db, then place it into some sort of array then use an array adapter to fill the list view. Is that correct? If so, is there some sample code because all I can find is code releated to ListActivites.
I've been using my Activity class to access my DB which made my program freeze sometimes.
So I decided to use AsyncTask instead to handle the DB.
My problem is I don't know how to instantiate my SQLite DB "TheDB" from AsyncTask's class
CODE:.............
This worked fine on the Activity class, but it I dont know how to use it here
TheDB's constructor is TheDB(Context context) but this class is not a "context" so how can i use my DB here?
I wanna set a textview as the values from SQLite when I click the ListView Here is my way...
