Hi
I want to remove a limitation from an app.
I found how the limitation is set:
Code:
for(int i = 1 ; i < 20 ; i++){
}
So I want to change the 20 to 50 or something.
Could someone help me with this
You can't replace a local variable. Instead, you can hook the method to do something before or after it's called or to completely replace it.

Okey. Could you tell me how to do that because I don't really understand.
I know how to hook a methode but then the problem that I have is i don't know how to acces the variables.
I mean if I hook onCreateOptionsmenu
Then I can replace that with some code I want right? But how do I access the variables from that app. For examlle check if a boolean is true?

Check the Development tutorial if you haven't already, as well as the Helpers page.
I'd also advise you to check some open source modules' source code to get a better grasp.
I'm not sure of what exactly you want to do, but here's a general example:
The class you're hooking:
Code:
class SomeClass {
final int mInt;
public Object someMethod(int param1) {
return SomeStaticClass.someOtherMethod(param1, mInt);
}
}
static class SomeStaticClass {
public static someOtherMethod(int param1, int param2) {
// Do something
}
}
Let's say you want to hook someMethod to replace it, but instead of using "param1" and "mInt" when calling someOtherMethod, you want to use "1" and "2". Your code would look something like this:
Code:
…
findAndHookMethod("com.package.SomeClass", lpparam.classLoader, int.class, new XC_MethodReplacement() {
@Override
protected Object replaceHookedMethod(MethodHookParam param) throws Throwable {
SomeStaticClass = XposedHelpers.findClass("com.package.SomeStaticClass", lpparam.classLoader);
int mInt = (Integer) XposedHelpers.getObjectField(param.thisObject, "mInt"); // This is the actual value of mInt — ignored
int param1 = (Integer) param.args[0]; // This is the actual value of param1 — ignored
// we ignore the actual values of mInt and param1 since we don't care about them, and use "1" and "2" instead.
return XposedHelpers.callStaticMethod(SomeStaticClass, "someOtherMethod", 1, 2);
}
)

UPDATE
I just had a word with one of their customer respresenative named Mandy, she sounded very pleasant and nice. After going through the whole dealing process she insisted that the minimum order to modify an item is 500 units. So if any of the manufacturers or businessman can order 500 HD2 then it might be possible that we can have a custom built Qwerty Keypads for our HD2.
By the way she also assured that the item is bieng checked by one of the quality checking teams and it will be available on the website pretty soon. So enjoy the beautiful keyboard since then.
Just found another website which is selling the same product. Have a look here : http://www.chinajiaho.com/mini-bluetooth-keyboard-for-ipad-and-smartphones_p1361.html
The Big Deal
Now while going through the product description i noticed quite interesting details:
It is almost simlar to the length / breadth height with our hd2.
HTC HD2 :120.5mm x 67mm x 11mm KEYBOARD:115mm x 60mm x 6 mm
What More !!
As specified on the website, they also have custom made keypads available if the product is bought on lots or wholesale of 500 and above number.
Now this is interesting as i am going to contact them and ask them strictly to this option whether they can make custom keypads with a hinge or a hook for an hd2, i would happily place an order of 500+ keyboards.
Dont you all think this would be a great addon for our HD2. If anyone interested please add your comments here, and lets make this idea into reality.
Imagine HD2 with a Qwerty Keypad .. This sounds to good to be true.
Price/Cost
And my last surprise to you, this is worth only only only USD 20
For more details you can go directly to the production description website : THE CHINAVASION WEBSITE HAS BEEN DELETED FOR NOT MEETING CUSTOMER NEEDS.
DO NOT BUY ANYTHING FROM CHINAVASION. BAD REP, BAD CUSTOMER SERVICE.

wow....really nice i think i will buy one if i found on uk teritorry.
Nice Keyborad, very very nice!
Are you sure it's not made in Kazikstan ...
lol. of course not.
I'll have 1 or 2
Put my name down please if you deal with them. I asked about a Keyboard the other day for the HD2 here and just come back to see if there was an answer or suggestion. yours is a good find.

Sold out .....
lol, check the word "Keyborad" on the images, wrong spelling. Typical "made in China" !
The keyboard itself looks interesting and will be very handy though. Really excited to try
I don't get why the OP is going on about bulk orders for modifying them. First of all we need to order 500+ to get them modified, then we only need 25+ to get them modified.
Why on earth do they need modifying in the first place? I'm lost.
i think he means 500+ to get them modified to an easier design to use with the hd2, and 25+ to buy now as they are.
How would it fit onto the hd2? or wont it at all. If it cant clip on, or you just hold it, what the point? lol you might as well have just got a phone with a keyboard...
otherwise ur gonna have to carrry around a huge keyboard with you everywhere.
silly idea im afraid, you wont get 500 people to buy them i can tell you that now..

hey mate thanks for correcting here, i actually didnt remove the other comments after updating, doing it now. thanks. the keypad can be modified only if we order above 500+ units. i am not a businessman so cannot ask them for such order. anyways when it will be available i will update my post. thanks though bringing it to my attention.
visually it reminds me of the rhodium keyboard.
I have to admit for occassional use it would be great, I don't tend to write articles and stuff on my pda any more, whereas I used to on my advantage all the time. I may be tempted if it felt good to use, which is the risk with some of these, they feel awful to actually type with
looks a very cheap price, most other sellers are charging twice that price.

I want one. For $20 you can't go wrong. Could be very handy for remote controlling many apps and may allow control of lots of games, etc I can't otherwise control because of lack of hard keys. When can we order??

I'm looking for a good VPN service which is cheap and secure, what do you all use and recommend?
These are cheap VPNs: NordVPN, SurfShark, CyberGhost, Trust.Zone.
when choosing a VPN, buy that does not save logs
ProtonVPN, NodrVPN, ExpressVPN
I use private internet access (PIA). No problems for now.
Try the ones which you find suitable for you then judge yourself which one is the best for you

Nord is Best
Both are Tegra2 devices
Both are using the same Wifi chips
Both are GSM/HSPA devices
Plan of action:
Get Xoom kernel for 2.6.32 (same level as the kernel we've got for Atrix)
Diff the two for platform specific changes
Get Xoom kernel for 4.1.2 release (http://www.xda-developers.com/android/motorola-xoom-gets-stock-rooted-android-4-1-2/)
Put in platform specific changes learned from diff
Then you should have a binary compatible Atrix-fied Xoom kernel, running on the Atrix. Which enables you to
Use Xoom hardware acceleration
Have a propper Project Butter experience
Have a kernel that doesn't run on the compatibility mode of bionic libraries
A more modern and mature Linux kernel (and libs)

Its a good plan, but woudnt the architecture be slightly different?
I really don't know what it means, but it was said very often in the forums:
Xoom = SoC T20
Atrix = SoC AP20h
But I hope that you can do some magic :silly:
Have you actually started this process or is it just a plan you hope will work?
Sent from my MB860 using xda premium
it's not only the cpu and antenna...there is also the camera,fingerprint and imo the resolution of the screen is also important...
so this kernel cannot be used...only some parts of it mabe
If is works, It will be a great dev but
is it possible?
Sent from my MB860 using xda app-developers app
Also, code names for these units:
Xoom = Stingray
Atrix = Olympus
https://android.googlesource.com/kernel/tegra/
Found the kernel source... Seems as though we are capped at 2.6.39, for now.

Finally someone that's thinking in the long term. Barring a kernel source leak from Motorola, this would be a way to go. Sounds like massive coding process though. Are you up to it? Do you have a plan?
Kudos for the idea.
I have XOOM MZ601, because of that I buy Atrix, it's the same machine...this will be great, and also tu put webtop ( I know I am boring, but I have lapdock and I desperately need webtop ):good:

Ok - some history:
I've worked at a mining communications/safety company Becker Mining Systems, for their R&D firm Becker R&D in South Africa.
We've developed an Android VOIP phone for to be used in mining (hazardous, please-don't-make-a-spark) environments. We've succeded, but then Germany practically canned their colleries (hug-a-tree-don't-kill-johnny-polar-bear) - resulting us to stop development 2 months before manufacturing (literally only had to make the moulds). Sigh - the collery overseers DSK was the contracting client.
My job was to get Android running on this Freescale iMX31 based platform. I did the kernel + Wifi + Android + VOIP and a bit of the UI.
Plan of action:
/arch/arm/ is the first point to go looking for things in the kernel. In this case, we'll be looking for /arch/arm/mach-tegra/, this is where all the platform specifics will hide away.
Compare board-olympus.c and board-stingray.c (+ board-olympus.h and board-stingray.h). Look for similarities, look for differences. These are the glue points - in this .c files the startup / fixup / powerup of the platform starts off. See it as the void main(void) file for the platforms.
Adapt the board-stingray.c in such a way that it starts up on the Atrix
After kernel start up, get the peripherals running. This includes UARTS (USB the most common, and debug), SPI (chats to other peripherals), MMC (chats to the WiFi/BT module) and also the screen.
Merge in libraries - we'll probably using the Atrix radio driver file, but the rest (Wifi, OpenGL libs) from the Xoom
If all of this doesn't make sense to you, please press the thank you button and refrain from commenting on this feed
Hmmm... yeah you are the right person for this job :laugh::good: :highfive:
I wish you to succeed, you would make lot of people to be really happy !
If you need testers, i'll be right there.
Jokersax already said its possible, in fact, he was using some Xoom binaries that he ported, but he also said that it required a MASSIVE amount of coding, time and skills to get it done.
Hope you can accomplish this dude! Good luck!

yeah well those didn't really make a difference... and we have the libs, only need a supporting kernel.

Indeed, he showed that it was possible.
It might help when nVidia goes opensource with the Tegra drivers, but so far I haven't seen enough details on that to be encouraged yet. I suspect that what we'll see will be either code dropped into nouveau or a separate driver set rather than nVidia opening up their proprietary drivers.
mvniekerk, please join Atrix Re-Birth Project.
We already have libs for Atrix, two leaked rom, closed kernel, useful CM 10 (I'm using it right now), great developers (Epinter, MMontuori, TPoint75...)
With your knowledge and enthusiasm we could go even further and faster.
This can be tested, it's very simple, dd the xoom boot partition to a file, then flash out back to the Atrix. If it passes the boot logo, there is hope...

mvniekerk: If you're serious about this undertaking, I'm sure there would be quite a few willing to donate, including myself.
In fact, I suggested something similar, but using the Galaxy R kernel as base ( http://forum.xda-developers.com/showthread.php?p=32274673, last post on that page). That is a 3.x kernel.

I have a Nook HD+ running SlimKat 4.4.4. The WatchESPN app has been running well for the most part. However, the app has a restriction that only allows Monday Night Football to be watched on desktops or tablets - not on phones. The app is recognizing my Nook HD+ as a phone and therefore is not allowing me to watch these certain broadcasts.
Does anyone know how to have my device actually be recognized as the tablet that it is? I have limited knowledge on where to look, but what I found so far that I thought may be relevant is that in the build.prop are the following properties:
ro.build.characteristics = tablet
ro.product.device = ovation
ro.product.brand = Android
ro.product.manufacturer = Barnes & Noble
ro.product.model = BN NookHD+
ro.product.name = slim_ovation
Thanks for the help.
You must backup original build.prop.
And change only model and brand.
Try this.
Galaxy tab 8.4 (wifi)
ro.product.model=SM-T320
ro.product.brand=samsung

I am making a unit converter app and at one point, I am converting grams to metric tons:
case "grams":
value *= 0.000001;
et.setText(Double.toString(value));
The output in the emulator is 0.0 instead of 0.000001 or 1E-6 .
Is there something wrong?
Thanks.
