General :: Migrating Between App 2sd Methods
Mar 7, 2012
I want to switch app2sd methods. I want to switch from the DT-A2SD method to Link 2SD, but any info will probably apply to all ext-based methods (i.e., not the built-in Froyo method). I can't possibly be the only person who's ever contemplated it!
Am I going to have to disable DT-A2SD first (which will involve a LOT of backups/uninstalling / reinstalling)? Will the Link 2SD app detect the ext partition and its apks and just adapt accordingly. I'm running MIUI 1.11.4 on an Acer Liquid E.

Migrating to a new Gmail account without losing everything Android related? Like a few people I know, I made a Gmail account a few years ago before android was this big and (like the naive child I was) didn't make a very professional email address. Migrating to a new Gmail account I created. Copying contacts and mail is easy enough, but what about everything related to Android?

I have application that I have been developing for over a year and half now. I used the app to teach myself Android programming. When I started the development Gingerbread was the main sdk and that is what I targeted. Well now ICS and Jellybean are out and I was looking at migrating my app from Gingerbread to the newer sdks.
How to most efficiently go about this process. I would like to keep everything in the same files if possible and not have to start from scratch.

I plan to upgrade to a 4G LTE device this year. Typically, my usage on my 3G device (a Droid 2 Global) runs less than 1 GB a month. Have any people experienced increases in their monthly data usage after switching to a 4G-enabled device? And if so, do you think it would be due to the fact that you're consuming more data at a faster rate, watching more videos, streaming more content through your cellular data network because of the increased capability?
I'm trying to decide between buying old technology off of a third party (e.g. Droid 4/Razr Maxx at no contract) or upgrading to the latest and best (GS3/Razr Maxx HD) for the same cost, but losing the unlimited.

I'm looking into writing simple graphics code in Android and I've noticed some synchronized() blocks. What is the reasoning behind this and how do I know when I should be "synchronizing" my code?

Getting a Hero next month and from an initial search on the web their doesn't seem to be an easy way to port over calendar and contacts from my centro to the Hero. Looks like it can be done (I don't use outlook) but just wondered if there were any easy tools, e.g., Sprite, that work for the old Palm OS.

Anyone know of any Android apps/utilities which will help me migrate all my data from a IPhone 3G with iOS 4.0.2 to a Samsung Vibrant? I just made the switch and I want to migrate my data (contacts, notes, calender and music) from my IPhone to my new Samsung Vibrant. Please, someone tell me this is not as difficult or cumbersome as I think by having to reenter all my data and there is a Android app/utility that can make this easy for me.

I work at a small company that fields autonomous android devices which programmatically connect to bluetooth telemetry devices. These devices require pins, so we need to automatically create a pairing in order to connect to the bluetooth devices. We DO have root access.
Since the new Bluetooth Stack in Android 4.2, I have been unable to use this common AIDL bluetooth reflection method in our private utility app:
Code:
public IBluetooth getIBluetooth() {
IBluetooth ibt = null;
try {
Class c2 = Class.forName("android.os.ServiceManager");
Method m2 = c2.getDeclaredMethod("getService",String.class);
IBinder b = (IBinder) m2.invoke(null, "bluetooth");
[code]...
The issue about this strategy no longer working is documented here. I previously used the setPin method as well as the createBond method from this Interface, and now I cannot.
Is there anyway to manually create a bluetooth pair profile under Android 4.2? Is there a database file where the profiles are stored that we can use root and sqlite3 to access?

I've been uploading music to my phone by copying and pasting entire folders via mass storage, but I am curious to know if there is a preferred way to do this. Especially if I want to create playlists *on my computer*, then have those playlists show up in my phone with the songs in the same order as they were organized on my computer.

I used to have nexus one, with Froyo 2.2. Unfortunately i dropped the phone one too many times and the LCD is cracked, hence i gotten myself a new HTC desire.
My questions:
1) how to i re install all my apps(previously installed on N1) to Desire. Besides trying to remember each app and manually installing them one by one
2) can i just use my old SD card (with music and Froyo, etc) from N1 and use it on desire? Or should i mirgate all data out, format using Desire and re use as a brand new card?

I have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service.
Bascially, I would like to start a new thread that will return a document of a specific url.

I've tried uploading several different movies, from several different formats, and only got 1 to play back. I've used Handbrake on a video that didn't previously work and only got audio through. Does anyone know exactly what format, settings, methods, etc. to use to get video on this phone?

So when messing around with Swype the other day I noticed that you can change the keyboard types to 'QWERTY' 'Phone Keypad' and 'Compact QWERTY'.Since I suck at using Swype and I came from a Blackberry pearl with sure type. I switched my keyboard type to Compact Qwerty. The keys are much larger using 2 letters per key, which is great for people like me with big hands.Now I can type so fast on this baby it still auto corrects and everything. To change at your home screen press menu > Settings > Language & Keyword > Touch Input > Keyboard Types.

So I'm writing an Android app which uses a large c++ library. I have everything working so that the java app can call the c++ delegation methods, but I'm finding myself wishing I could log messages from c++ to the Android log. This is easy from java, but I'm at a loss as to how to call a java method from c++. My searches found methods for opening a jvm from c++, which is not at all what I want to do. Ideally, I'd like to pass a log method pointer to c++, which could then be used whenever I wanted. Of course, java doesn't support method pointers.

I have a MapView where I would like to be able to tap the map to create a new item at that location if there is no item there, or display the info about the item if there is.
I tried overriding both the onTap(int) and onTap(GeoPoint, MapView) methods but apparently if the second method is overridden the first never gets called (commenting one or the other lets each one work as I expected).
I thought about just checking if an item was at the location, but there doesn't seem to be any handy methods available to do that (other than iterating through the list of items and checking each manually).

I know rule #1 of optimization is: don't do it! But I figured this was an easy question, and if I start using the faster method now I can save a lot of cpu time when I'm finished.Now, the answer to my question may be "there's no difference" and that's fine with me. I just want to know.

Need help closing/accessing my views in a simple app (included an img of my program layout) but I might have been too confusing. Basically, I have an app that has a main menu where the user can click a button to open a camera. The user then snaps a photo and it is displayed on a page. The user will then click another button that detects faces. If faces are detected, the user is sent to a final page that shows the cropped face, etc. I give the user the ability to return to the main menu or snap a new photo.
Let's say a new photo is snapped and the user does it a few more times. Now I have multiple saved instances of old snapped photos (presented on the layout). How do I kill the previous instance (the layout from before he decided to snap a new photo)? So when I try to close the app it doesn't go back to the previous instance (displayed layout of said snapped photo). I am so confused on this one thing.

I have an Java class with a static final method getAll:
CODE:..............
Now I want to hand in null as a value for the where statemant so that it will just be ignored later on in the code. Anyway in the testcase for this method I have: Vector<Category> categories = Category.getAll(context, null);
Which then in turn gives me a NoSuchMethodError. I don't know exactly why it does that. The only thing I could imagine is that the null I hand in would not match the signature of the above method. But how can I overcome this? I already thought of overloading. But this would just end in rewriting most of the code. At least when I do it, how I think.
This is the stack trace I get:

I am curious whether the AIDL only serves for inter-process communication between several Android apps on the same device, or AIDL provides much wider functionality. Let's say I have a Java application running on some server, is it possible to remotely call methods on that server through AIDL from an Android phone?If yes, do I need some extra libraries on the server-side Java application?
