[android-developers] Partition confusion
Hello, would someone from Google mind explaining the current strategy behind the various partitions? I'm a little bit confused. - In the beginning /sdcard was used for external storage, but since you could not rely on the mount point across vendors, the proper way to access it was the Environment class (or the convenience methods in Context). - Since 3.x an increasing number of devices use /sdcard for an additional internal storage that can not be removed. The docs have been reworded and tell me I now have to think about external storage in a different way. The Environment class only knows about the primary external partition. - Some devices still come with a real SD card. That seems to be mounted as /mnt/sdcard2. Some even support USB Host and /mnt/usbdrive. Now my questions: - What it the proper way to access non-primary external partitions? Should I rely on the above mount points? - What are those non-primary partitions actually used for? Can I only access them with a file manager? Are they scanned by the media service? - Is there a plan to add a proper API that helps me deal with them?

[android-developers] Re: Trouble: Windows XP detecting Nexus One by USB
Same problem here. XP32 SP3. Here's what I did/see: - I took same care to make sure no instances of older driver files were on my computer. - I then manually installed the new R3 driver that was downloaded by the SDK Manager. - I plugged in both my ADP1 and my Nexus One. Both have USB Debugging enabled. - In the Windows Device Manager I see 2 x Android Composite ADB interface - adb shell lists the ADP1, but not the Nexus One. - When mounting the SD card, I can see files on the ADP1, but not on the Nexus One.

[android-developers] Re: JDBC Driver for SQLiteDatabase
Hi Kris, yes, this is the general bugtracker for the Android open-source project. Please use it. I think it is adequate also for documentation issues or feature requests. I don't know about your specific issue, but the issues are being looked at by the Android team (mostly Google guys) and worked on. For instance, I filed a small feature request for DDMS, and the feature is now part of the SDK. Cheers, Joerg On 10 Dez., 17:13, kristianlm kristianl...@gmail.com wrote: Ok. Thanks a lot Joerg!

[android-developers] Re: JDBC Driver for SQLiteDatabase
There is JDBC support in Android (see online reference for package
java.sql). There is also a built-in, though somewhat limited JDBC
driver for SQLite. Try this inside an Activity:
try {
String db = jdbc:sqlite: + getFilesDir() + /test.db;
Class.forName(SQLite.JDBCDriver);
Connection conn = DriverManager.getConnection(db);
Statement stat = conn.createStatement();
stat.executeUpdate(create table primes (number int););
stat.executeUpdate(insert into primes values (2););
stat.executeUpdate(insert into primes values (3););
stat.executeUpdate(insert into primes values (5););
stat.executeUpdate(insert into primes values (7););
ResultSet rs = stat.executeQuery(select * from primes);
boolean b = rs.first();
while (b) {
Log.d(JDBC, Prime= + rs.getInt(1));
b = rs.next();
}
conn.close();
} catch (Exception e) {
Log.e(JDBC, Error, e);
}
Unless you really need to write or maintain portable code, I'd still
recommend using the SQLite interface in the android.database package,
because it's nicely integrated with the UI classes (ListActivity and
the like).
Cheers,
Joerg

Why is no such JDBC driver already included in Android?
Android does not support JDBC.
Am I missing the big picture here?
Android is designed to be used on devices with limited RAM, limited CPU,
limited storage space for application code, and limited electricity
(battery), to connect to local databases.
JDBC is designed to be used on devices with lots of RAM, lots of CPU
speed, comparatively unlimited storage space for application code,
full-time AC power, to connect to local databases and database servers.
Why would you not want to interface the built-in SQLite engine
through JDBC?
You lose performance, battery life, and on-board storage space, all of
which are in short supply in an Android device.

[android-developers] ListActivity style question
Hello, I want to create a ListActivity that looks like the ones in the settings application (two-line items, separators, inverse section titles). Can I inherit these styles from something built into android.R (and can I rely on these style names being stable across versions?). I tried referring to style=@android:style/TextAppearance_WindowTitle in my XML, but the Eclipse plugin doesn't like it. Doing it in Java code would also be fine, as long as it's a way that keeps up with future or different versions of the framework.

[android-developers] Layout broken on Cupcake device
Hello, I have a rather simple XML layout that contains a TextView, an EditText and three Buttons. It worked fine on 1.0 and 1.1. It still works fine for Cupcake when launched in the 1.5 SDK emulator. If I install the application on an ADP1 device with Cupcake, though, the text in one of the buttons is suddenly considered too long and, as a result, wrapped into two lines. I can easily fix this by changing the text or the padding around my layout, but I still find it curious why the behavior is not consistent across versions, emulator and device. Is this interesting for the framework guys? If so, I can post (or mail) my XML layout. It's not too much.
