Does a phone have to be unlocked before rooting or custom ROM installation will work?

HippoMan — 2012-05-26T14:27:42

I have purchased and successfully rooted a few of Android devices in
the past, and I have also installed custom ROM's on most of them after
rooting ... such as the Cyanogen ROMs. However, each time in the past,
I had performed these actions on an unlocked device.

Now, I'm thinking of purchasing a locked phone (myTouch 4G Slide from
T-Mobile), and I'm wondering if the phone's locked status would
prevent the rooting or subsequent custom ROM installation in any way.

In other words ...

1. If I purchase a locked phone, will the commonly used rooting
procedures that work on unlocked phones also work with a locked phone?

2. If I do manage to root a locked phone, will the fact that it is
locked prevent the installation of a custom ROM, such as one from
Cyanogen?

3. A related question: if I indeed root my locked phone and install a
custom ROM, if at a later date I want to unlock the phone (by
purchasing an unlock code), will the fact of the phone being rooted
and running a custom ROM prevent it from being unlocked? Or is the
unlocking solely dependent on phone hardware and independent of any
software or OS version that it might be running?

Thanks in advance for your insights.

Application temporarily free

Hilario Perez Corona — 2012-05-26T03:47:45

I'm gonna explain what i have:

1. A free Lite version of my application
2. A full paid version of my application (.99 USD)

Both applications have different package names.

Now, what i want to do, is publish my full paid application for free for a 
limited time only.

I've been reading a lot for 2 days now, and i don't find any solution that 
looks nice to me, and i really don't understand why is there the limitation 
of not being able to change from free to paid an application. Whichever 
technical issue should be solved. (well, that's my point of view).

The solution i've came up is to create a new application with a new package 
name appending "promo" at the end, with the full version inside, and 
publish/unpublish it as required... The problem that i see is that i won't 
be able to take advantage of the ratings, downloads, and the users won't be 
able to upgrade until a new "promotion" kicks in...

So far, is the best option i've came up with... Any ideas or suggestions?

Thanks in advance.

starting avd fails, saying it can't find emulator, but it exists

David Karr — 2012-05-26T02:35:55

I've installed the SDK on Ubuntu 12.0.4. I started up the SDK manager
and updated several packages.

I ran the avd manager and tried to create an avd, but it just failed
with no information.

I then tried to create the avd from the command line, using the same
information I tried to use from the gui, and it worked.

When I tried to start that AVD, it failed with (some strings elided):

Failed to start emulator: Cannot run program "<myhome>/apps/android/
android-sdk-linux/tools/emulator": java.io.IOException: error=2, No
such file or directory

This is what I see when I look for this file:

$ ls -lt <myhome>/apps/android/android-sdk-linux/tools/emulator
-rwxrwxr-x 1 <me> <me> 24828 May 25 08:20 <myhome>/apps/android/
android-sdk-linux/tools/emulator*

As you can see, the path it's looking for DOES exist.

What's going on here?

Menu button deprecated in 3.0

RLScott — 2012-05-25T22:45:27

I just found out that the menu button is deprecated starting with
Android 3.0, and that some Android devices do not even have a menu
button.  My app targets Android 2.2 and uses the menu function quite a
bit.  Is it really possible that someone with a 3.0 or later device
might not be able to access my menus?  It seems that even devices that
don't have a dedicated menu button still have the soft menu icon in
the upper right on the same line as the app name.

Avoid handling of intent twice

pbuda — 2012-05-25T21:04:21

Hello,
I have a small issue. I have one activity which handles the
ACTION_SEND intent. Everything works as expected, however when
orientation changes, the intent is handled again. What should I do to
handle it only once?

I'm android noob so I might have missed some important thing in docs
but I'd still be grateful for any tips.

Thanks.

Thumbnails and picking picasa images from gallery on ICS

Thomas Fjellstrom — 2012-05-25T19:55:25

I'm having a hard time getting Thumbnails.getThumbnail to work with
picasa photos on a Nexus S running ICS. Everything else seems to work
including getting the original image from picasa and displaying it,
but the getThumbnail doesn't seem to work. I'm getting the following
errors when attempting to use it:


    E/MiniThumbFile( 1852): Got exception when reading magic, id =
5745625138093120418, disk full or mount read-only? class
java.lang.IllegalArgumentException
    W/MediaProvider(  540): original media doesn't exist or it's
canceled.

The disk is not full, it is read-write, the app has external storage
write permissions, and the picture does indeed exist on picasa (I can
view it through the android Gallery app).

The same code works fine on Android 2.3, but it follows a slightly
different path, as 2.3 seems to download a copy of the photo and hand
you the actual local file:// uri to the newly downloaded image, rather
than hand you a content:// uri.

This is the main meat of the code in question:

      public void addImage(Uri uri, boolean local)
      {
         ContentResolver resolver = getContentResolver();
         Uri actualUri = uri;

         Log.d(TAG, "addImage: original uri: " + uri.toString());

         if(local) {
            try {
               List<String> uriPath = uri.getPathSegments();
               String contentUri = Media.insertImage(resolver,
uri.getPath(), uriPath.get(uriPath.size()-1), new String());
               actualUri = Uri.parse(contentUri);
            }
            catch(java.io.FileNotFoundException ex) {
               Log.e(TAG, "FileNotFoundException: ");
               ex.printStackTrace();
            }
         }

         Log.d(TAG, "addImage: actual uri: " + actualUri.toString());

         List<String> uriPath = actualUri.getPathSegments();
         long imageId = Long.parseLong(uriPath.get(uriPath.size()
-1));

         Bitmap thumb = Thumbnails.getThumbnail(resolver, imageId,
Thumbnails.MINI_KIND, null);
         if(thumb == null) {
            Log.e(TAG, "Failed to get thumbnail for our image.");
            Toast toast = Toast.makeText(getApplicationContext(),
"Failed to get thumbnail for image. Please try again.",
Toast.LENGTH_SHORT);
            toast.show();
            return;
         }

         uris.add(uri);
         bmps.add(thumb);
         notifyDataSetChanged();
      }

That method is called when ever a new photo is added to the
application's "collection" of photos. When its known to be a local
image (ie: if a photo was taken from inside the app, or
onActivityResult's data argument is null), the local parameter is set
to true and I attempt to get a content:// uri back from the media
content provider so we can get a valid image id to pass to
Thumbnails.getThumbnail. That code works fine for images gotten from
the Camera app (via startActivityForResult), as well as images from
the gallery that are stored locally on the device. I originally wrote
a bunch of custom thumbnail generation code, but I'd prefer not to use
it if I can use a built in function.

I'm a bit stumped.

Voice Actions: can commands be overridden?

bsquared — 2012-05-25T18:11:50

Hello,

Is it possible to override the voice actions to either change the
activity run for a command or introduce a new command?

Long click on Search button. Voice Search dialog opens and ...

Example.
Open an app other than Navigation when the key phrase "navigate to"
are recognized.

OR

Example.
Open an app when a new key phrase is recognized.

If this is possible, is there some documentation or examples
available?

Thank you.

Regards,
Brian

How to handle dismiss of DialogFragment (support lib) while app is in background

Chuck Krutsinger — 2012-05-25T17:08:18

I have an AsyncTask that may need to dismiss a FragmentDialog upon 
successful completion.  In a regular Activity, the dismissDialog() method 
correctly handled removing a dialog even if the app was in the background. 
 However, using a FragmentActivity and a FragmentDialog, there is no 
equivalent approach that I can find.  The compatibility library does not 
have dismissAllowingStateLoss() like the real DialogFragment class does. 
 If someFragmentDialog.dismiss() is called while the app is in the 
background, I get a crash with an IllegalStateException.

What is the correct way to dismiss a FragmentDialog upon completion of an 
AsyncTask so that I don't get this exception?

permission to access another apk's assets/ directory

Latimerius — 2012-05-25T14:31:39

Hi all,

I'm slightly confused about when applications are allowed to access
other applications' data.  I believe I've read all relevant parts of
the Dev Guide like the "Security and Permissions" article or
android:sharedUserId and signature-level permissions documentation but
after running some tests I'm still surprised by what I see.

In particular, I've set up two .apk's.  Both are created with Eclipse
ADT and (I believe) signed with the same debug key but other than
that, they have nothing (that I'm aware of) in their manifests to make
them special to each other.  In one of them, I use

createPackageContext ("the.other.package.name", 0)

to get the other APK's Context.  I use the returned Context to access
the other APK's assets/ directory the usual way (I call getAssets() to
retrieve an AssetManager reference which I then use to call open()
with a file name to get an InputStream).

Now, the part I'm confused about is that it works! ;-)  I thought it
would fail until I introduce sharedUserId, or perhaps use a completely
different mechanism (like a ContentProvider?).

Am I messing up somewhere, or is this the expected outcome?  Or, does
it work because both applications are (probably - I'm not totally sure
what Eclipse does behind the scenes while creating and building
projects) signed with same key?  I might also be misreading the Dev
Guide security docs when they refer to "application data" - does that
mean stuff in assets/ or res/, or just anything an application writes
to the SD card (should I say "external storage")?

Also, does it mean anybody can read my assets/ if they know the file name?

Thanks in advance for any insight!

Adding paths in make files

Hi,
During my PhD project, I added two
files (.c and .h) into taindroid vm folder : /tdroid/tdroid-2.3.4_r1/
dalvik/vm
 My question is should I add them into make files /tdroid/
tdroid-2.3.4_r1/dalvik/vm/Android.mk and /tdroid/tdroid-2.3.4_r1/
dalvik/vm/Dvm.mk?
If not, where exactly should I add them ?
Thx a lot for your help.

anti-debug tricks in Android

vejey karthick gandier — 2012-05-24T05:04:45

Hi,

I have anti-debug checks like IsDebuggerConnected() and CRC checks.
I am interested in using NDK with ptrace to hook it to the process so, 
other debuggers can't get hold of it.
I'm actually looking for a way to self-debug the application by itself, so 
other debuggers an't attach to it.
I know it is possible. Any insight / code on how I can achieve this? 

Thanks,
Vejey

what is the minimal memory needed to download android source code?

thinke365 — 2012-05-24T03:39:42

since the network connection here is not so stable, so i got a vps to
download android source code, but was surprised to find it fails every
time near success, the problem is not related to internet connection
on vps, since it is quite well, but the fault have something to do
with memory.
the error always happened at the process of index-pack, especially at
the index-pack process for prebuild.git project, this is quite a huge
project which occupies more than 5.4GB.... and it seems index-pack
operation will invoke malloc() function oftenly and may use much
memory,
so the question is, what is the minimal memory needed to download
android source code?

Why the CTS Resutls are different with same devices, same android source code and different Wireless AP

pinglunliao — 2012-05-23T08:00:59

Dear All:

I followed the CTS instruction steps to run CTS five times for the
same device with same modified android source (provided by freescale).
However, the target device was connected to different Wireless AP each
time.


The following table shows the results:
---------------------------------------------------------------------------------------------------
