General :: Use System PIN Dialog In Android Application

Apr 11, 2012

I am trying to write an application which works like described below.When user start application it check if user have registered PIN on his device.If user have registered PIN, application must show button "Continue with PIN".When user press on button "Continue with PIN" system standard PIN dialog must appears.User enter his PIN and press "Continue" button.After System must check if entered PIN is correct or no and continue working.

I have made some researches and find some articles on stackoverflow and other internet sources which say "There is no way to develop a new custom unlock mechanism on a non-rooted phone." or "I would be surprised if you could, because then you would be probably able to steal the pin code, and I don't think anyone would want that.".

Also I have watched some video tutorials like Tutorial: Android Internals - Building a Custom ROM, Pt. 1 of 2 and Tutorial: Android Internals - Building a Custom ROM, Pt. 2 of 2.

Decision:So I think that the only way to get access to the Android system PIN dialog is to root the phone make some changes in the system files and use system PIN dialod

getting access to the system PIN dialog in the rooted phone.

Android : Invoke System Dialog For "Connect To" Secured Network?

Feb 23, 2010

My application needs to establish a new Wi-Fi connection to a secured network. The catch is that the application does not know the password/key/passphrase or whatever it is called for WEP/WPA. And it should not know!

In such case, I would like my application to invoke the system "Connect to" dialog. Only the system WifiManager should remember this password, and the fact that my application is not involved should be obvious to the end user.

Is this possible? I thought that it should be similar to using Intent() for android.content.Intent.ACTION_SEND to send a picture with another applications.

Android : Progress Dialog When Application Starts

Jun 23, 2009

I am trying to initiate a progress bar when my application starts. The way my application works is that it collects info from the db that takes around 5 to 6 secs where the screen is completely black. I am trying to initiate a progress dialog that gets triggered WITHOUT a button click or any other UI interaction but just when the user starts the application. All the previous posts handled something with handlers and UI interactions.

Android :: Display Droid Dialog Out Of Application?

Sep 7, 2010

I have an application that is designed to pop up a question when a phone call ends using a BroadcastReceiver and a PhoneStateListener.

My problem is, when a call is received while the user is not currently using my application, the dialog is not displayed until the application is manually started. I would like either for the dialog to be displayed on top of what ever context the user is currently in, or that my application will be focused.

How is this done?

Android :: Generic Task Manager Class For Application / No Dismiss Dialog

Nov 15, 2010

I have a class which extends AsyncTask, which is intended to serve as a generic task manager class for my application. The strange behavior is that the progress dialog shows up, but is never dismissed. I am sure that onPostExecute() gets called for every task instance, as any Log.d("","") statements fire if placed in here, even the Toast messages show up from within this method, but I am not able to dismiss the static dialog. I understand that AsyncTask(s) have access to UI thread at only 2 places [onPreExecute() and onPostExecute()], so I think trying to dismiss the dialog in runOnUiThread() is unnecessary. All calls to executeTask() are made from different onCreate() methods of different activities that need to fetch some data over network before populating some of their UI elements, and I always pass the current activity's context to the tasks. As I do not switch activities until after the related tasks are completed, I believe the activity context objects are still valid (am I wrong to have assumed this???) I have never found any of them to be null while debugging.

Could this be a timing issue? I have also observed that most of the times DDMS shows all tasks get completed before the activity is displayed. If I use new Handler().postDelayed(runnable_which_calls_these_tasks,10); in the onCreate(), and add delaying code in foo_X(), the activities are displayed without any delay, but the dialog will just not dismiss(). I have read through quite a number of articles on this issue but am still not able to figure out exactly where am I going wrong. I do not want to define each task as private inner class Task1 extends AsyncTask<> in all of my activity classes and I would not want to (unless this is the only solution) load my application object with all activity references either as mentioned in this discussion: Is AsyncTask really massively flawed or am I just missing something?. I have spent a week on this and am absolutely clueless :( It would be great if someone can guide me, and let me know what am I missing. Following is the class definition: [I've removed some irrelevant application specific code for clarity]

public class NetworkTask extends AsyncTask<Void, Integer, Boolean> {
private Context UIcontext;
private int operationType;
private static ProgressDialog dialog;
private static int taskCount;
private NetworkTask(int operationType Context context){ this.UIcontext = context;
this.operationType = operationType;
if (taskCount++ == 0) dialog = ProgressDialog.show(context,"","Loading...");
}

public static Boolean executeTask(int operationType, Context context) { return new NetworkTask(operationType, context).execute().get();
} @Override protected void onPreExecute(){ super.onPreExecute();
if (taskCount == 1) dialog.show();
} @Override protected Boolean doInBackground(Void... arg0) { switch(operationType){ case TYPE_1: foo1();
break; case TYPE_2: foo2(); break;
case TYPE_3 foo3(); break; case TYPE_4: foo4(); break;
} @Override protected void onPostExecute(Boolean result) { super.onPostExecute(result);
taskCount--;
if (dialog.isShowing() && taskCount == 0){ dialog.dismiss();
}else { Toast.makeText(UIcontext, "Task#"+ operationType+", m done, but there are "+taskCount+" more", 5).show();
} } }

Android :: Application For Tasks - Reference System

Oct 18, 2010

Greetings. Years after reading the GTD book and trying all sorts of apps and methods, I still can't find myself settling for a todo system that's simple and effective using my phone. I'm always looking for threads and articles on task managers, but most are only people spouting "I use generic todo app xyz and it rules!" Never how they practically use it in their daily lives. So, I'm asking all of you: what apps do you use for tasks and maybe even reference systems, and HOW. This might be useful for all procrastrinating couchpotatoes like me. Right now I'm using something very simple: Mobisle Notes, with 2 lists: a sorted "Inbox" which is basically just all tasks that come to mind (Sorted as in, priority first, then due date, then projects, then random stuff) And a today list with 5 actions I want to do today. Far from perfect, and Mobisle doesn't handle tags and moving of tasks from list to list a hassle, which keeps me on the lookout.

Android :: Repackaging System Classes In An Application

Jun 16, 2010

I came across this today and was wondering does this work in production app or does it merely work because my phone allows non market apks.

Here is an example, Take a class like, android.view.IWindow, and copy it's source into your project and recompile it after changing a few things. (Don't rename or repackage it).

Now when your APK loads in the VM, something odd happens.

CODE:...

So the logging is a little ambiguous, but is it saying that the classes in this APK are blocking out previous versions and that these new classes aren't being verified. If so I hope this is only succeeding because as developers most targets are in development mode when allowing non market apks (non rooted phones). However does this work in market released apps as well? This seems like a really nasty security exploit if I can override system interfaces just for my application.

Android :: How To Repeat Login Dialog And Progress Dialog?

Jan 25, 2010

I am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

Android :: Slow Gallery 3d System Application Alternative

Oct 12, 2010

I hate how slow the Gallery3D system app is. It's been slow on both my Motorola Droid & HTC Incredible running various ROMS, including stock. It's ridiculous, actually. The HTC Gallery is great by the way it organized photos and is easier to use, but isn't an option for an AOSP ROM [afaik]. Does anyone have a recommendation as to what my other options could be? Thanks, and please don't flame.

Android :: Application Compatible With System Assigned Permissions Automatically

Apr 7, 2010

I've noticed a troubling issue with app permissions. It seems that after installing, some apps that didn't ask for these two permissions:
Storage: modify/delete SD card contents
Phone calls: read phone state and identity
will magically acquire them after install! These apps do not ask for these permissions during install, nor do their Market pages disclose that they need them. After looking through many logcat messages during an install, I found this:
04-07 03:23:08.973,I,PackageParser,1016,com.some.app.nam e.here: compat added android.permission.WRITE_EXTERNAL_STORAGE android.permission.READ_PHONE_STATE

Digging around, I found this online:
Android permissions: Phone Calls: read phone state and identity - Stack Overflow. It seems that an app that is compatible with systems earlier than 1.6 will automatically be assigned those two permissions. If a developer is willing to make their app compatible only with 1.6+ systems, they can change their app's manifest:
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4" />
and when users on 1.6+ devices install the app, those two extra permissions won't show up.

I bet a lot of app developers don't know this, and therefore their apps will seems to acquire those two permissions magically. Users will install those apps, see the two extra permissions when they inspect the app security setting and be very puzzled. They'll probably think the app is malware and uninstall it. I've contacted some app developer about this issue, so that they can (hopefully) fix their app so it doesn't look like malware. Unfortunately, until all legit apps are fixed, it'll be hard to distinguish amongst apps that have those permissions, which app actually needs those permissions, which apps need fixing, and which apps are malware.

Android :: Showing Dialog After Another Dialog Hangs

Sep 2, 2010

I have a really weird problem, which I am unable to debug so far. thing is. my app needs to download something to work. So in the beginning of the onCreate() method, I check if that something is already downloaded. If not, I pop a dialog up asking the user to download it.My dialog is shown and I am clicking, so aManager.install() is called. I am passing the context because that aManager.install() pops up a ProgressDialog to show downloading progress and spawns a new thread in which everything is downloaded. So obviously before creating my dialog I make a Handler to receive the response from that aManager.install(). And the response MAY vary, because for example the internet connection isn't available (Exception raised and catched and listener called with different code).Now, when that happens (Exception) I would like to call another dialog saying "something went wrong, would you like to retry?" so another call to showDialog(DIALOG_REINSTALL) (this time with another code).thing is the showDialog() gets called (I can verify this by logging) but the dialogs doesn't show up. Instead my application JUST HANGS Does someone have a clue why it's doing this? No exception raised, absolutely nothing from logcat, I can't tell WHERE it's hanging...just see that the method is called and the dialog should be displayed.
