Hi,
I have a question about management of SQLite DB in Android. I see that in the class NotePadrProvider of Android examples there is this method
Code:
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + NOTES_TABLE_NAME + " ("
+ Notes._ID + " INTEGER PRIMARY KEY,"
+ Notes.TITLE + " TEXT,"
+ Notes.NOTE + " TEXT,"
+ Notes.CREATED_DATE + " INTEGER,"
+ Notes.MODIFIED_DATE + " INTEGER"
+ ");");
}
Can you tell me why are not used transactions and, at the end, the DB is not closed? I don't think that googles are bad developers.
Thanks in advance.

I have a question about RIL.java invokeOemRilRequestRaw function.
Code:
public void invokeOemRilRequestRaw(byte[] data, Message response) {
RILRequest rr
= RILRequest.obtain(RIL_REQUEST_OEM_HOOK_RAW, response);
if (RILJ_LOGD) riljLog(rr.serialString() + "> " + requestToString(rr.mRequest)
+ "[" + IccUtils.bytesToHexString(data) + "]");
rr.mp.writeByteArray(data);
send(rr);
}
Where to configure which file or raw memory to read or write for invokeOemRilRequestRaw function? I read many codes, but didn't find which file or raw memory to read and write. Please help.
The source code is android 2.3.5.
You found any solution for that?
Also can you please tell me why you are trying to invoke this functions.
I am also interested. Did you find a solution?
Hi all,
I am currently doing some changes to the CM7-Framework and therefore need a custom option.
I wrote a simple app to test it and it doesn't work. The app has 3 Buttons
turnOn, turnOff and check
and one TextView for output.
Clicking turnOn does:
Code:
boolean success = Settings.System.putInt(getContentResolver(), "USE_BUTTONS_ON_NOTIFICATON", 1);
textView1.setText("set USE_BUTTONS_ON_NOTIFICATION to 1, success: " + success);
Clicking turnOff does:
Code:
boolean success = Settings.System.putInt(getContentResolver(), "USE_BUTTONS_ON_NOTIFICATON", 0);
textView1.setText("set USE_BUTTONS_ON_NOTIFICATION to 0, success: " + success);
and check does:
Code:
try {
int value = Settings.System.getInt(getContentResolver(), "USE_BUTTONS_ON_NOTIFICATION");
textView1.setText("USE_BUTTONS_ON_NOTIFICATION is: " + value);
} catch (SettingNotFoundException e) {
textView1.setText("Setting not found");
e.printStackTrace();
}
Both buttons return true, but check always says that the option is 1.
Is it even possible to change Settings like this? The app has the WRITE_SETTINGS permission.
If it is not possible, what would be a good way to ìmplement an option set by an app and read by a class inside the framework?
New to the forums, short introduction? Hi. Next on the agenda I'd like to apologize for this not being in the development forum, but as I'm a new user I was unable to post there.
As for my issue I'm working on a game, it's very basic right now and I'm working on an editor.
(Terribly sorry about this part. Turns out I don't have privileges for image links quite yet. Hope I get there soon! )
So far for rectangles I use the Menu button -> Objects -> Rectangles; Drag and drop to create a shape, press Ok. Drawing multiple rectangles from the map array works perfectly fine, but collision is another story. The most recent object I create HAS collision, if I create a new object, the previous object loses it. e.g. I create 100 rectangles, 1st - 99th don't collide. I have coding experience, asked multiple people. All have been stumped on something that seems like it'd be simple.
The saving:
Code:
if (confirmMode && touchX > (startX + endX) / 2
&& touchX < (startX + endX) / 2 + tileSize * 20
&& touchY < (startY + endY) / 2
&& touchY > (startY + endY) / 2 - tileSize * 10) {
map.add(key, startX);
map.add(key + 1, startY);
map.add(key + 2, endX);
map.add(key + 3, endY);
key += 4;
confirmMode = rectMode = circleMode = false;
}
The reading:
Code:
while (i < key) {
canvas.drawRect(map.get(i), map.get(i + 1), map.get(i + 2),
map.get(i + 3), red);
if (playerX > map.get(i) && playerX < map.get(i + 2)
&& playerY > map.get(i + 1) && playerY < map.get(i + 3))
allowed = 0;
else
allowed = 1;
i += 4;
}
i = 0;

Hi all..
I am not sure this is the right sub-forum to post in, but here goes.
I am working on an app that uses a GoogleMap and lots of overlays/markers. Controls and navigation is handled automatically (no direct user interaction with the map needed so far).
Things work the way I want right until the app pauses and goes into the background. When I resume the app the map has zoomed out to 0:0 and it doesn't react to animateMap or anything anymore. I can't seem to figure how I get it back to the state where it doesn't react to user interaction and actually updates with my markers and stuff..
Below are the three methods handling the map, and it doesn't seem to react on any of it after a resume. Any hints?
Code:
private void setupMap(){
getSupportFragmentManager().beginTransaction().replace(R.id.trackeractivity_map, new SupportMapFragment()).commit();
FragmentManager fragmentManager = getSupportFragmentManager();
SupportMapFragment supportMapFragment = (SupportMapFragment) fragmentManager.findFragmentById(R.id.trackeractivity_map);
mMap = supportMapFragment.getMap();
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mMap.setMyLocationEnabled(true);
Log.d(TAG, "Max zoom level " + mMap.getMaxZoomLevel());
}
private void updateUserLocation(double lat, double lon){
Log.d(TAG, "updateUserLocation - " + lat + " : " + lon);
mLastLocationLat = lat;
mLastLocationLon = lon;
CameraPosition userPos = new CameraPosition(new LatLng(lat, lon), mMap.getMaxZoomLevel()-4, 0, 0);
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(userPos));
}
private void updateMapOverlay(double lat, double lon){
Log.d(TAG, "updateMapOverlay - " + lat + " : " + lon + " - Type " + mCurrentType);
MarkerOptions marker = new MarkerOptions();
marker.position(new LatLng(lat, lon));
marker.draggable(false);
marker.icon(BitmapDescriptorFactory.fromResource(getTypeDrawableID(mCurrentType)));
mMap.addMarker(marker);
}

That, unfortunately, didn't help.. Still does the same thing.. Bugs the crap out of me..
Maybe it is just me, but how do i set UISettings on the map? There only seems to be a method to get them?

Hey,
a few months ago I read somewhere that android stores the wifi passwords in plain text (seems to be known since 2010: http://forum.xda-developers.com/showthread.php?t=794555 but no one cares?!)
Because I don't want my wifi password to be stored that way, I searched for a way to store the wpa passphrase. This wasn't difficult, because android usese wpa_supplicant, means I just had to find out my passphrase and replace the plain key in /data/misc/wifi/wpa_supplicant.conf with it. Everything still works fine and my phone is able to connect to wifi.
Now my question is: is there a way to store every new wifi password this way? It's annoying to have to edit the wpa_supplicant.conf file manually...
One problem is, that it seems like android doesn't have the wpa_passphrase binary included, even if the source code seems to exist in the wpa_supplicant repository ( https://android.googlesource.com/platform/external/wpa_supplicant_6/ ).
If someone could tell me, how to build the code (I'm not familiar with the ndk), I could try writing an app, which replaces all plain text passwords with the passphrases.
But it would be awesome, if it were possible to integrate this feature in a custom rom, so no more passwords are stored plain text.
Best regards,
David
Finally, I was able to build CarbonRom from source and found a way to integrate this in the rom! On my device, no wifi password is stored in plain text anymore It took a long time to figure out what file I have to change but finally, I got it
If you are interested, I could create a patch and post it here but I don't know how to submit patches to github.
The only thing that confuses me: I found out, that the SSID I use to generate the password hash is quoted. Means, ThisIsASSID is stored as "ThisIsASSID". But actually the password hash should be wrong because it doesn't use ThisIsASSID. Anyway, it works And the password in wpa_supplicant.conf is hashed.
Edit: Cheered too soon... The wpa_supplicant.conf is probably just read at boot time. After a reboot I couldn't connect to my wifi anymore... But if I change the hash in the wpa_supplicant.conf file manually to the right one it works, so now I have to solve the quoting thing. But that shouldn't be difficult.
So, all problems solved now
Here is a patch I created, if anyone is interested:

I didn't found a place in the java code so I directly edited the c code of wpa_supplicant
