[INFO] All about: strings and howto change the Useragent of the stock Browser (XWJP6)

Here is my first post.
I've found some very interesting things in the android stock browser code (BrowserActivity.smali) of the Galaxy S.
Here are all about: strings that you can enter in your address line of your stock browser.
about:blank (shows a blank page. Found near .line 1867)
about:debug (shows in the preferences screen some Javascript options. Found near .line 585)
about:useragent (VERY INTERESTING: You can change the useragent and you can choose between an Android, Iphone, Desktop, Lismore UserAgent or you can enter a custom UA string. Found near .line 610)
Here are the about: strings that I don't know what are they supposed to do:
about:debug.dom (Found near .line 587)
about:debug.dom.file (Found near .line 589)
about:debug.render (Found near .line 591)
about:debug.render.file (Found near .line 593)
about:debug.display (Found near .line 595)
about:debug.drag (Found near .line 597)
I don't know if these commands are working on earlier firmware versions. If you know what the commands are supposed to do post it please here

Nice find, will look into this

Nice find!
I am especially intrested in making sites think I am using desktop PC.
I did change my useragent, but it seems the galaxy also sends a header called "HTTP_X_WAP_PROFILE:" where the phone reveals its a gt-i9000. Some sites seems to listen to this.
Do you think there is a way to change these things more permanently with root access maybe?

you could use my patched browser for example

Possible reason for poor battery life

interesting news about improving battery life:
Lee!!!!
Ive found out where the missing power management options has gone wrong
For some reason HTC misplaced the .apk and put it in /system/bin instead of system/app
You will find it /system/bin/NvCPLSvc.apk and it needs moving to system/app.
For users who already have LeeDroiD installed, use a file manager with root access and move NvCPLSvc.apk from/system/bin to system/app and reboot.

Trying and failing for a 3g/1x mod on LJ7.

I've been going through the NetworkController.smali in LJ7 trying to find the right "if-nez~" to # out to get a legit 3G/1X mod. Unfortunately there are 21 different instances of the bolded line below. I've compiled 21 different SystemUI.apk's to find the right one. In the area I live I generally don't have 3g which should make it easy for me to find which line is the right one. It's not... Not one of the ones I've flashed have given me the results I am looking for.
To any other dev out there, am I missing something or have I gotten it and just have really been on 3g all this time? (lol?) If anyone else has had success, would you mind telling me the ".line ####" to look for?

[Q] Need to Suppress Wireless Charging Notification

There are some threads on this for other models, but I am looking for info on how to remove wireless charging notification for my Sprint version. I assume this will require root and I have no problem with that.
Here's the scenario. I modified my Sprint phone to accept the Verizon wireless charging rear cover, while preserving NFC. (Email me if you want the link cuz I don't have sufficient privileges to post it).
Placing the phone on the charger gives a pop-up notification and tone that wireless charging has begun. Then wireless charging is complete (100%) and charging stops. Then the phone sits on the charger for a few minutes, drops to 99% full and wireless charging begins again, meaning another beep. This is an endless cycle and the constant beeps are driving me crazy.
I have turned off all volumes, all notifications, placed on silent, etc., but the "Starting Wireless Charging" tone and notification is still present.
Really would like to get this fixed as inductive charging is awesome, but not if the phone is gonna beep every few minutes.

Does it bulge the battery cover slightly?

Just look for the mod to remove full charge notification, I believe all the different charging notis are housed in the same location. The VZW disable mod *should* also work as long as you do it manually and don't flash any zips with their updater script included.
I like to break stuff!

@freeza: I did a 10 minute mod to the Sprint phone using cooper conductive tape, so no soldering or opening the phone. Now it accepts the Verizon Wireless Charging back cover. So the cover is stock, its just Verizon, not Sprint. I can't post the link to my how-to (XDA rules), but just Google for "How to EASILY Add Inductive/Wireless Charging to your Sprint Phone Using Verizon Cover & Keeping NFC" and it is the first link.
@EViL-KoNCEPTz: I just successfully rooted today, never had the motivation before now but I absolutely have to get rid of this notification.
In researching this, I found the post quoted below -- by Freeza coincidentally. So now I just need to learn how to: (1) Get to the /com directory (that directory doesn't seem to be listed in my root explorer app); (2) learn how to compile; (3) learn how to push the compiled file to the phone and (4) learn how to change permissions. Of course, I'll also have to locate the "wireless charging begin" file, which is hopefully in the same location as you predict.
Lots to learn. Sucks being such a noob.

Actually, I'm not overly concerned with the pop-up message (""WIRELESS CHARGING: You have placed the device within range. Now charging wirelessly."). I really just need to suppress the corresponding alert tone.
With my new found root access, I looked around (system/media/audio/ui) and found many audio files, but not the one that is triggered when wireless charging begins. Should I be looking somewhere else or does this tone not use an ogg sound file?

SOLVED
I feel a little stupid, but will post this anyway in case someone else has the same problem. The beep was coming from the wireless charging pad, not the phone. Who knew? Opened up the pad, pulled the tiny speaker, put it back together and problem solved.
Note that you do have to delete charger_connection.ogg from /system/media/audio/ui to get rid of the phone sounds, or simply turn down the volume on notifications.
Many thanks to freeza who helped me back channel; he was the one who figured this out. He also created a mod to suppress the "wireless charging has begun" pop-up.

I had the same problem
I recently came across the XPosed framework and have developed a module for it that:
Prevents the screen from turning on when a charger is connected
Disables the wireless charging popup
Disables the beep when a charger is connected
Prevents the screen from turning on when the battery is full
I will post a module once I've got past the min 10 post limit on dev threads
In the meantime I hope this helps...

Disable end call beep

The end call beep is EXTREMELY loud when connected via bluetooth to a car or headset I haven't measured but I'd have to say it is in the 80-90 db range on my cars. Anyone know how to disable it? I've done a google search and while the question is common, the answer seems elusive. I've seen one solution that was a modified Phone.apk file. I went looking for the M9's Phone.apk but haven't found it in system/app or priv-app. Some older android version seem to have a setting option to turn it off but it is sporadic and no where to be found on the M9. Others have suggested a play store app but the app only adds an end call notification, it doesn't stop the existing one.

I believe I've located the offending piece of code. It is in the telephony.apk. Who can modify the attached apk to remove the beep? I'm guessing you would be able to simply set the TONE_CALL_ENDED integer to 0. The apk is from @andybones stock deodexed rom.

I don't see "TONE_CALL_ENDED" in integers.xml

Well that's no good. I was hoping it would be an easy change. Found an online decompliler and fed it the telephony.apk. The TONE_CALL_ENDED variable was defined in the CallNotifier.java file. I'm learning as I go here so I'm not sure I'm giving useful info. Just found apkstudio and am now poking through it to see what I can find.

I have the telephony.apk decompiled and found the variable definition in:
smali/com/android/phone/CallNotifier$InCallTonePlayer
I must be missing something trying to recompile though. I get told there are some missing resources.

There is a variable defined named TONE_CALL_ENDED with a value of 0x5. I just changed it to 0x0 to match TONE_NONE.
I did finally get it to compile but when I replaced the original I had no service, didn't look like it even loaded the replacement apk. Not sure what happened there.

If you get it to work on the M8 I'll test it too. It'll make my wife happy. She has the same complaint. Where do I look to see why it didn't like my recomplied apk? I didn't see anything obvious in the logcat.

I believe it had something to do in the last method of the smali file ".method public stopTone()V", but not too sure, i tried changing a few things but couldn't get it, sorry my friend.

Figures it wouldn't be easy. I can't believe no one at google or HTC thought that a loud tone at the end of every call would be a good idea.

Potential progress. If I comment
Code:
invoke-virtual {v1, v3}, Landroid/media/ToneGenerator;->startTone(I)Z
or
Code:
[STRIKE]invoke-direct {v1, p0}, Lcom/android/phone/CallNotifier$InCallTonePlayer$1;-><init>(Lcom/android/phone/CallNotifier$InCallTonePlayer;)V[/STRIKE]
in the CallNotifier$InCallTonePlayer.smali, the tone does not play. I have noticed that the speaker phone selection does not get reset now when I end a call. Not sure what else may be going on yet. It looks like commenting startTone prevents the tone from playing and doesn't cause any other side effects. I haven't tested yet but I'm guessing it will also not play call waiting tones. I will report once I test it.

Confirmed, no call waiting tones either. Ideally we'd need an if statement and only invoke startTone when something other than the end call tone is selected. My smali skills are not up to that yet. I also can't seem to get things to output to the debug log to see what v1 and v3 are. If I can work that out then it should be possible.

Nice work my friend . :good:

Solution
Got it. If anyone wants to implement it, here's how I did it. I modified the run method of the CallNotifier$InCallTonePlayer class. The tone id for my M9 is to be 27. I got this by spitting the tone ids out to the debug log. For reference the call waiting tone is 22.
To start I bumped the .locals by 1 so I didn't have to worry about clobbering another register that was in use. This was on line 269 for me.
Code:
.method public run()V
.locals 13
#Was locals 12, upped to disable the end call tone
.prologue
const/16 v4, 0x25
const/4 v10, 0x2
const/4 v5, 0x1
const/4 v2, 0x0
const/16 v0, 0x50
The rest of the edits are around the call to startTone around line 630
Code:
const/16 v12, 0x1b
if-eq v3, v12, :cond_20
invoke-virtual {v1, v3}, Landroid/media/ToneGenerator;->startTone(I)Z
:cond_20
The code will now skip the startTone call if the tone id (v3) is 27. The resulting apk is attached, feel free to use it. I verified and now get call waiting tones but no end call tone. If you want to use it just replace your existing apk in recovery. Be careful of permissions if you do this.

3.37.605.7 (Marshmallow) has changed things up a bit. The run method starts around line 295 and already has locals a 13 so we bump to 14.
Code:
.method public run()V
.method public run()V
.locals 14
.prologue
.line 2611
# getter for: Lcom/android/phone/CallNotifier;->VDBG:Z
invoke-static {}, Lcom/android/phone/CallNotifier;->access$600()Z
move-result v10
if-eqz v10, :cond_0
The call to startTone is now around line 681 and some variables changed registers.
Code:
.line 2863
const/16 v13, 0x1b
if-eq v8, v13, :cond_20
invoke-virtual {v6, v8}, Landroid/media/ToneGenerator;->startTone(I)Z
:cond_20
:try_end_2
.catchall {:try_start_2 .. :try_end_2} :catchall_0
Modified Telephony.apk attached.

3.37.605.13 added.

Could you do another upgrade for the Nougat App?
I do have this deafening End Call tone and it is always ringing out my eardrums.

what is the apk that controls the end call tone in Lineage Os system.
Because there is no telephony.apk file

Yes, if this is fixable in lineage nougat, that would be just awesome!
