Re: [android-developers] USB host
Yes, it may be. That indicates that the hardware (adapter etc.) is ok and
thus the device is recognized on the linux/os level but it's not made
visible on the level of the android USB-Host api (it's the same e.g. with
usb mice etc.). It may be that android tries to use it as some standard
rs232 hardware or as serial mouse or something.
That's probably also the reason why Sick USB 2 Serial Terminal does not
find your device: it's not visible on the api level.
Like Tux, I would recommend using another kind of device too. The IOIO is
great, but depending on your use case, it may be overkill. There have been
other projects with usb 2 serial adapters. You may find recommendations via
Google.

If you can see your device in the android tab, then you are right and
it's a software issue.
I'm not sure about the device_filter.xml. Do you have to specifiy the
values in hex or decimal? The docu uses e.g. class=255 and does not use a
hex-only digit. That looks to me like it could be decimal?

AppWidgetProvider is also a BroadcastReceiver,and I think you also can enable or disable it through your code.But I don't know whether it would work because I don't see AppWidgetService.java parse the enabled attribute and how it deals with that attribute.Get a try.Hope that can help you. 在 2013年3月1日星期五UTC+8下午3时31分50秒，abhay_401写道： Hi, When the user long press on Homescreen, he will get some options, Widgets is one of them.

[android-developers] Re: Adopting Android 4.0+ ONLY app development policy with an app currently supporting 2.1+?
Thanks for the replies guys. Richard, can you confirm that if I made changes to the app that would prevent it from being available to older devices (say i changed the minSDK from 2.1 (API 7) to 3.0 (API 11), users with those older devices stop getting updates to the newer app version, but is the old version of the app still available to the older devices, ... and this is what they see and download? Is this the method that Google apply? Seems logical. But I'd really like to know. Thanks.

[android-developers] Re: Obfuscating code
You could obfuscate these strings you're using in the reflection calls. This makes it a bit harder to find them literally. However someone still could look for occurrences of uses of reflection and figure out these things. A great source of information about protecting your app is this Google IO session talkhttp://www.google.com/events/io/2011/sessions/evading-pirates-and-stopping-vampires-using-license-verification-library-in-app-billing-and-app-engine.html. I implemented almost all of these suggestions in one of my apps and just got after 5 months of being out on the market a crash report that showed me that somebody tried to crack it. The crash occurred within one of my hidden anti-piracy handling code blocks and the cracker apparently changed some bytes of one of my obfuscated strings and that finally caused the crash. So the bad news is: they will try to crack it. The good news is: they don't necessarily do a good job at it. And you can actively make it harder and basically postpone the date when your app is properly cracked. I think there are the following key elements that make it harder for a cracker to crack your app: - Code obfuscation of course - Using several different self-integrity checks: - package signature - package name (avoid re-packaging) - check for set debug flag and randomly crash in a background thread with random delay while your app is being debugged - check for integrity of files in your APK (CRC) - Redundancy of your anti-piracy code. Don't perform these self-checks at just one location of your app. Spread it all over the place in background threads - Regular updates of your app And also another great advice from that Google session talk: use the NDK. Compiled native code is harder to reverse-engineer and you have more possibilities for obfuscating your code. Java is pretty straightforward to decompile up to the point were you almost get the original code back (minus comments). This looks a bit different for native code. Create a native library that does all these self-checks in addition to your Java self-checks. But also make that library indispensable for your app. You need to migrate some vital business logic of your app into that library so a cracker cannot just remove it and all calls from your Java code to it. However, it is also important to understand what kind of battle you are fighting by protecting your app to that extent. I read some statistics about game apps, that half of their total sales occur within the first six months or so. So you could say it's about buying some time when it comes to piracy. But I think that's debatable unless you have a triple-A game on your hands everybody wants to play, most people who pirate stuff don't care about getting the original. They can wait. The biggest problem in my opinion are people who try to steal your hard work and sell it as their own. The only way to make your app more or less bullet-proof is by letting the bulk of its business logic run on your own server. The server checks the app for a valid purchase license and unless somebody hacks into your server or your server code has exploits, there is little purpose in trying to crack the app. On Friday, March 1, 2013 9:22:39 AM UTC-6, dashman wrote: So I'm trying to obfuscate my code I'm using reflection to get the package name. i also plan to use proguard. i understand variables xxx and yyy will be abfuscated by proguard. android.content.pm.PackageManager xxx= (android.content.pm.PackageManager)yyy.invoke( context ); but if the code is decompiled, will the decompiler be able to assign xxx to a PackageManager variable. also packageInfo.signatures; i understand packageInfo will be modified by proguard - what about signatures property. if nothing is done about that - the user could just search for that keyword.

[android-developers] Re: Obfuscating code
Unless your server provides something like downloadable content or
functionality for your app I don't think you need to go through the trouble
of implementing the license verification through your server. Doing it
within your app is just fine, because either way a cracker can still look
for these license check code portions and change them. Doing it just within
your app is less work of course, so I'd go for that.
Regarding the LVL there are a few very important things to know about.
Google never intended it to be taken verbatim as a drop-in solution for
protecting your app. A lot of developers did that. And their apps can be
easily cracked. The problem is that a cracker also knows the original LVL
code.
You probably already know that the LVL needs to be customized for each app
and definitely should not be used as an all-in-one solution library you
just reference from your app project.
So basically you should copy the files into your app project and change the
heck out of it so it's not recognizable anymore. Also all logging lines
must be removed. Why they are there in the first place is a bit beyond me.
Anyway, the one big problem of the LVL is that its entry point interface
ILicensingService apparently cannot be obfuscated. Proguard's
documentationhttp://proguard.sourceforge.net/index.html#manual/examples.htmleven
says:
If you're using Google's optional License Verification Library, you can
obfuscate its code along with your own code. You do have to preserve its
ILicensingService interface for the library to work:
-keep public interface com.android.vending.licensing.ILicensingService
That advice is absolutely misleading and basically opens a big door into
identifying and cracking your app's LVL self-check. If the interface name
ILicensingService is literally to find in your obfuscated Java code you
have basically the entry point for cracking the app right there. With Java
decompiler it's just another click away to find the response code check.
The Google session talk mentions that you should obfuscate the whole LVL,
including ILicensingService. However, when I tried to do exactly that, it
simply did not work. The name was always kept as if there is a hard-coded
rule inside Proguard that makes the obfuscation of that identifier
impossible. So I simply renamed ILicensingService. And it still works. I
tested it extensively.
About using the NDK for self-integrity checks: it's actually pretty similar
to using reflection in Java. First of all you also have the same problem
here with string literals that basically give away what you're trying to do
(class and method names). You need to obfuscate them.
One unobfuscated NDK example of getting the package name:
void Java_com_example_JniTestClass_checkPackageName(JNIEnv* env, jclass
clazz, jobject context) {
jclass ctxClass = (*env)-GetObjectClass(env, context);
jmethodID getPackageNameMethodID = (*env)-GetMethodID(env, ctxClass,
getPackageName, ()Ljava/lang/String;);
jstring packageName = (*env)-CallObjectMethod(env, context,
getPackageName);
}
Each JNI method is basically the native counterpart of a Java method
declaration. The Java original might look like as follows:
public class JniTestClass {
public static native void checkPackageName(Context context);
}
I'm going to dissect the NDK code a bit:
jclass ctxClass = (*env)-GetObjectClass(env, context);
This gives you the class object of the context object. This is necessary
for retrieving the class method getPackageName in the second line:
jmethodID getPackageNameMethodID = (*env)-GetMethodID(env, ctxClass,
getPackageName, ()Ljava/lang/String;);
This gives you a class method handle. This is necessary for calling that
method in the following line. The last argument looks a bit cryptic. It's
Java convention for expressing the method signature in a string notation.
You can find more information about these signature strings on this
pagehttp://dev.kanngard.net/Permalinks/ID_20050509144235.html
.
jstring packageName = (*env)-CallObjectMethod(env, context,
getPackageName);
This gives you the actual package name as a Java string object. It's not a
C-string yet. With another JNI function call you can convert it into a
C-string. You need to make yourself familiar with JNI. It looks awkward but
it isn't that bad in the end.
Reading the package info works pretty similar. You always need a jclass
object then you can use that for retrieving a method or field member and
then you can use JNI for calling that method or for reading the value of a
field.
A few more words of advice. You should also obfuscate these native method
names. You cannot do that with Proguard because that would break the link
between your Java code and the native library. After all there must be a
way for JNI to find these native methods and Proguard's obfuscation is
random. You should apply non-sensical method names as Proguard would do:
Re: [android-developers] Re: Obfuscating code
Really the *only* way to really protect against anti piracy is to perform mission critical operations on a server, at least some of the time, and enforce a good strategy to make sure that can't be cracked. Doing checks in native code can be circumvented, what makes you think they can't? Albeit, it's harder to crack your app. In reality, there is not really anything you can do to crack proof your app unless you have a pretty significant security background. Even then, your app can probably be cracked by a skilled adversary. But of course, anti piracy is a cost / benefit analysis. By the way, putting in that number of days requirement doesn't fundamentally change things, the cracker can just remove that check. To have a server help, you need to perform critical operations *on* the server. kris On Fri, Mar 1, 2013 at 11:41 AM, dashman erjdri...@gmail.com wrote: Thank you for some excellent suggestions.

Re: [android-developers] Re: Obfuscating code
The common theme here is that these are all naming tricks.
This helps to make your code hard to read for a human hacker, but
doesn't do anything to prevent an attacker with a good static analysis
framework.
A static analysis framework can usually deobfuscate (turn these
nameless classes into named things or common patterns) simply by
matching call/return sequences in a standard way using machine
learning.
So while you can prevent a human from saying that's the licensing
check! I'll look there! a computer can take in a bunch of known
good code using a licensing check and then training it, then taking in
the obfuscated app, looking at traces and saying here's the licensing
check and using program slicing to patch it out.
Hopefully this gives more insight into why the small lexical tricks
don't really help,

Re: [android-developers] Re: Obfuscating code

Re: [android-developers] Re: Obfuscating code
I think you took my answer to be dismissive of yours, or to try to discourage people trying to learn about piracy. I find it kind of strange you took it that way, since I was trying to say you were right :-) To clarify, the whole point of my post is that piracy is a cost / benefit trade off. It's disingenuous to tell people that their app will be safe just by using LVL, etc... There are real static analysis problems that you didn't mention. While I agree with your post, I wish you'd stop to think that I was indeed supporting you before you try to imply I'm derailing people from learning about piracy: that's explicitly not my point.

Encryption is working fine. But while decryption it is throwing the

me if any other asymmetric algorithms to work on large data.

Both Stack Overflow posts your refer to assume that both Activities try to control the display. But the whole point of his post was that he has one that does not use the display at all. So these do not apply. That said, I am a little surprised it works, too. After all, though there is no requirement that an Activity do display, that is usually the case, so it is the best tested case. I doubt the case the OP is doing is heavily tested at Google, but he seems to have lucked out; perhaps because it is less demanding to get it working and keep it working.

[image: root-samsung-galaxy-note-10-n8000]http://www.9android.net/wp-content/uploads/2013/03/root-samsung-galaxy-note-10-n8000.jpgAndroid 4.1.2 ZSBMB1 Firmware Details: PDA: N8000ZSBMB1 CSC: N8000OZSBMB1 Version: 4.1.2 [image: odin3-screen] Steps for Updating Galaxy Note 10.1 N8000 to ZSBMB1 Android 4.1.2 Jelly Bean Official Firmware 1. Download and Extract *N8000ZSBMB1_N8000OZSBMB1_TGY.zip* to get a file with .tar extension in the unzipped folder. You will then extract Odin zip file to get Odin3 v3.07.exe. 2. Switch your tablet off. And make sure that you wait 5-6 seconds to confirm complete the power down cycle. 3. You will then put your Galaxy Note 10.1 N8000 tablet in Download Mode by pressing and holding down the Volume Down button, alongside Home and the Power button, until the screen flashes the Samsung Logo. After a few seconds of that, the tablet will enter download mode. 4. Run Odin3 v3.07.exe with Administrator rights. 5. Now that you are all prepared to root your tablet, connect your Galaxy Note 10.1 N8000 with your PC. You will then see a notification appear in Odin in the bottom left saying “Added!!”. If for some reason, you do not see the said notification, try another USB port. If that too doesn’t work, then reinstall the USB driver. Once you successfully see the “Added!!” notification in Odin, you are good to go. Also, check for COM port being depicted by a number in ‘yellow’ to make sure that you have successfully added your device. 6. Select the following files in Odin at their respective tabs from extracted *DVBMA2* firmware folder : Click the ‘PDA’ Button, and select the .tar file extracted in Step 1. - Click the ‘Phone’ Button, and select file with *modem* in its name (Ignore, if this file does not file exist). - Click the ‘CSC’ Button, and select file with *csc* in its name (Ignore, if this file does not file exist). Click the ‘PIT’ Button, and select the .pit file. Use only if you got it while extracting in step 1 above, otherwise ignore it. - In Odin window, make sure Auto Reboot and F. Reset Time checkboxes are selected. Please make sure that Re-Partition checkbox is selected, only if you are using a .pit file. - Hit the ‘START’ button to begin the flashing process. - Once the flashing process is completed, the tablet will automatically reboot and you will see a ‘Green’ PASS notification in the top-left-most box. You can unplug the device from the computer now. If you have followed every point described in the guide, your Galaxy Note 10.1 N8000 should now be running Android 4.1.2 Jelly Bean build N8000ZSBMB1.

[android-developers] When and how are LayoutParams examined, aside from onLayout and onMeasure
I have a custom ViewGroup that's only ever managing the size and position
of one child. I've override onMeasure and onLayout so that LayoutParams
are never examined, yet it fails unless I do provide LayoutParams. Here
are abbreviated summaries of the relevant portions of the class:
public class SomeSpecialLayoutManager extends ViewGroup {
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
measureChildren(widthMeasureSpec, heightMeasureSpec);
int w = mChild.getMeasuredWidth();
int h = mChild.getMeasuredHeight();
w = Math.max(w, getSuggestedMinimumWidth());
h = Math.max(h, getSuggestedMinimumHeight());
w = resolveSize(w, widthMeasureSpec);
h = resolveSize(h, heightMeasureSpec);
setMeasuredDimension(w, h);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
mChild.layout( 0, 0, mWidth, mHeight );
}
}
Using the above, the following *does* work:
LayoutParams lp = mChild.getLayoutParams();
lp.width = mWidth;
lp.height = mHeight;
mChild.setLayoutParams( lp );
But since neither `onMeasure` nor `onLayout` even makes reference to
`LayoutParams`, I wonder why it's required, or even how it's referenced at
all. I would assume that since the layout pass grabs `mWidth` and
`mHeight` directly, there'd be no need for the `LayoutParams` at all - and
that a call to requestLayout would update it appropriately.
However, when I isolate the above in a small program outside of a
complicated View tree with scrolling layers that exceed normal container
sizes, it *does* work as expected, so I have to assume the issue is in the
measure pass.
I've read as much documentation as I can find about what's going on during
the measure and layout passes, and examined the source, but I believe I
must be missing something.
TYIA.

Re: [android-developers] How to enable and disable mobile network programmatically ?
You could use ConnectivityManager.setMobileDataEnabled(false) - that will just take down data (and mms).
