Android :: Can't Register To Receive Screen Off Intents From Manifest

Aug 24, 2010

I have an application that listens for screen off, and user present intents. Since you cant register to receive screen off intents from the manifest, I am registering them in a service. Do I really need to have a whole service to ensure that I always get notified of when the screen shuts off, and the user unlocks the phone? Seems really wasteful :-(

The code I use in my service:

@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "Service created.");
// register receiver that handles user unlock and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_USER_PRESENT);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenReceiver();
registerReceiver(mReceiver, filter);
}

Android :: To Unregister A Broadcast Receiver Register Registered In Manifest File

Mar 19, 2010

I have been able to register and unregister a broadcast receiver from the java code and know that a broadcast receiver is unregistered (even if it is not done explicitly) on its own as the process that registered it is killed. Now I have a broadcast receiver which has been registered through manifest file and not through the java code, and need to unregister the broadcast receiver from the java code. Since this, i think would need a reference to System context that instantiates the broadcast receiver.

Android :: ActivityNotFoundException On Explicit Class Declared In Manifest On G1

Sep 30, 2009

I have some code that starts another activity based on a menu item selection:

..........

I've spent quite a bit of time on this and am inclined to file a bug report at this point. I can see a reference to the allegedly missing class in the classes.dex file inside the APK and the code works properly in the emulator. I haven't been able to find anything like this, so if there is, an RTFM pointer will be humbly accepted.

Android :: Register Get / Set Hooking Callback Function At Class

Apr 7, 2010

I release a class. In the class, there are public fields that can be written. I want to register the callback function which will be called right after my field is accessed. I think I can do that by using JVM tool interface which is supposed to be used for a debugger software. JVM tool interface:

I'm not sure same interface is working on android. or, They provide another form of interface to get a notification of a field access.

Android :: Access Application Class From Class Other Then Activity

Sep 8, 2010

I'm new to Java and android development. In my application I need data which is accessible for a few activities. I've read that a good solution is to use Application class for this. So I use it like this:

public class MyApplication extends Application {
private String str;
public String getStr(){
return str;
}
public void setStr(String s){
str = s;
}
}

and I can access this variable from activity like this:........................................

Android :: Permission Enforcement In Application And Manifest

Jan 10, 2010

I have two applications A and B (in different packages). A can send an explicit intent to B to perform some kind of action. Then,I enforced a permission in application B called "my.permissions.B_PERMISSION ". The A application can still call B despite the fact that it doesn't have the appropriate <uses-permission> in its manifest. Have I understood something wrong?

Android :: Internet Permission In Application (Manifest XML)

Mar 5, 2010

One of my users is experiencing an odd problem on network access via my application. Checking his logs shows up the following exception. The odd thing is that I have "android.permission.INTERNET" in application AndroidManifest.xml and many users have already used my app with no problem (I've launched it 4 months ago).

Android :: Can We Register A File Type To Application?

Nov 9, 2010

I use my file explorer a lot. It eliminates much of the "You have to put the files here" sort of requirement of many applications. And in many case - movie files for example - when you touch the file, it opens it in the appropriate application. There are exceptions like *.epub files. When I touch one, I get the famous "...does not support." message. So the question is, can I "register" Laputa (for example) to be the app to open *.epub files - Similar to the File Types dialog in Windows?I suppose this might require root access?

Android :: Good Way To Register Users From Phone Application

Jul 22, 2009

We have a web application and we've built phone applications (iPhone, Android, BlackBerry) to be companions to the site. The usual workflow is that an existing user of the site gets a phone app and then plugs their existing credentials into the phone app and they are off and running, but more often now we are seeing folks who are downloading the app and then (and this should not surprise anyone) don't read the help screen that explains they need to go and get credentials at the web site and therefore cannot connect to the application which does require registration to manage their content. This is a giant usability fail condition.

So we know that we need to put user registration workflows on the phone app. Other than the obvious solution of duplicating our registration page on the mobile, does anyone know of a better identity solution for the phone? For example, on the desktop we also use Facebook Connect as an identity server and the users love it. I'm looking for something that simple that we can implement across the major smartphone platforms.
Clarifying note: I should add here that this registration mechanism is likely to; and it would be desirable if it did, go hand in hand with a general identity/authorization mechanism such as the Facebook mechanism mentioned below. One other place I'm poking around is to see whether there's an openId solution that does not require a browser to pop up.

Android :: How Can I Register My Application On Andriod To Handle Type Of QR Code?

Oct 19, 2010

The built-in barcode scanner application on Android (based, I think, on zxing) reads QR Codes and launches that data into an application based on the leading text. For example, "BEGIN:VCAL" might launch a calendar application; "http:" might launch a browser.How can I "register" my application so the OS (or the Barcode application) will call it for a specific type (i.e. leading characters) of QR Code text?

Android :: Register Application For Files And Documented MIME - Type

Jan 28, 2010

I want to register my application for files of a certain popular and well-documented MIME-type. The problem is that Android does not seem to recognize this MIME-type. The following sample code demonstrates this:

package com.example.helloandroid;
import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView;

public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android"); setContentView(tv); String extn = android.webkit.MimeTypeMap.getFileExtensionFromUrl("/data/a.xyz"); String xyzMimeType = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension (extn); Log.d ("HelloAndroid", "extn: " + extn + " | xyzMimeType: " + xyzMimeType); }

Motorola Droid X :: PDANet - Cannot Register Application Button Disappeared

Aug 2, 2010

I love my Droid X. I downloaded PdaNet and paid for it. I received the receipt and clicked on the Pdanet tray icon and hit the register button. I wasn't smart enough to use copy and paste for the serial number and I typed it in instead. Tried three times (my typing isn't that bad) and all tries failed and the register button disappeared from the icon. I have tried to obtain help from PdaNet but no luck so far. The app is worthless to me if I can't access secure sites so I am ready to go in a different direction unless one of you can give me a suggestion for registering PdaNet.

Android :: 'Application Class Stick Around

Aug 12, 2010

In my application, I use a subclass of the Application object to store some references to complex objects I need to access from all of my activities. When my app starts, the startup activity checks one of these references, in this case a Location, and if it is null, it starts the LocationListeners which populate the reference for further use.If I back out of the app to the launcher screen, and re-launch it, the Application object still has the reference from the previous use a few moments prior. This is fine, and is what I'd expect, but I'm curious how long the Application object is kept around once I've back'ed out of my application? (onDestroy() has been called on all activities, nothing in the stack.)When is it finally killed? I know it does finally get killed as when I've not used the app in a while, it will search for location on startup (indicating the aforementioned null reference.)

Android :: Application Class Being Called Twice

Oct 16, 2010

In my Android application, I overload the Application class, and I updated the tag in my manifest. This application also creates an Android Service. I have put some logs in the onCreate of my Application class, and I see it being called twice. The first time is when my application gets launched (this is expected) and then, it's usually right after the Service is being created. the log also shows that a second instance of the Application is being created. (I print the "this" value and they are different). I thought the Application would be created as a singleton. Is that happening because I create a Service?

Android :: Application Package 1.6 - Class Rightaway

May 4, 2010

I have developed an application which has several packages within it's project. A class in one of those packages is called right away in the first line of code, which throws the dreaded java.lang.NoClassDefFoundError error. I don't get it, the package simply is within the project, and it works fine on my Android 1.6 device, but won't work with my 1.5 device. I do have to say that the project was originally set for 1.6, but then I changed the within the manifest from 4 to 3. Is that bad practice? Or maybe it has nothing to do with the platform version? Also I do get these lines as wel from the DDMS :

05-04 17:24:59.921: WARN/dalvikvm(2041): VFY: unable to resolve static field 2 (MANUFACTURER) in Landroid/os/Build;

Android :: Extending Application Class And Broadcast Receivers

Nov 1, 2010

In a book I read, the author suggests to extend the application class in order to have a place to be used as a singleton. In this way, it is easy to make some initialization stuff in it onCreate().Now my question: if my application has also some broadcast receivers declared in the manifest, and the application was not started explicitly, or it was but then the os reclaimed it resources back, what will be happening if the broadcast receiver is triggered? Will the onCreate of the application class be called first?

Android :: Violation Of Core Library Class Not Existing In Application

Oct 29, 2009

After getting comfy with the Android 2.0 environment and emulator (for the most part), I took the next step to bind <myapp> against the latest Android 2.0 jars: android.jar and maps.jar. The existing code (working in Android 1.6) did not need any changes to compile, but the app doesn't build due to a weird error message that prevents the build. See snippet below, drawn from the Eclipse Console. I have no aspirations to run up against any core library classes, and I am not aware I do. In other words, I am not implementing SealedObject (or any other core class that I am aware of) that would run up against Dalvik. Not in the javax, java or any other namespace. Anybody got any pointers what's going on here?......

Android :: Create Custom Global Methods In My Application Class?

Aug 17, 2010

I currently have an app that has many activities and needs to have a way of maintaining state between these activities.

I use the Application class to do this, declaring my global variables and using getters and setters to interact with my activities.

I was hoping to place a few custom methods in there, so that when I want to do a common task like, for instance, display an error message, I can declare the method in my application class and call it from any activity that uses it

EscarApplication application = (EscarApplication) this.getApplication();

EscarApplication being the name of my application class above.

I have tried to include this method in my application class:

CODE:.....

In the hope that I can call this method from activity without having to redeclare it, but when I call it using something like below I get an null pointer exception:

Visit.this.application.showError("Update error", "An error has occurred while trying to communicate with the server");

Visit being the name of my current activity above.

Should this work, or can I only use getters and setters to change global vars in an Application Class.

EDIT Stack Trace:

CODE:...............

The dialog is declared as such in the application class:AlertDialog alertDialog;

Created in that same class:alertDialog = new AlertDialog.Builder(this).create();

And the method to call it in that class is as follows:

CODE:.............

And finally, it is called from an activity like so:

CODE:........................

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 :: All .class Files In My Java Application Loaded Into Memory After Appliaction Start?

Feb 3, 2010

I am making an app for Android, in my Activity I need to load an array of about 10000 strings. Loading it from database was slow, so I decided to put it directly into one .java file (as a private field). I have about 20 of these classes containing string arrays and my question is, are all the classes loaded into memory after my application is started? If so the Activity in which I need these strings would be loaded quickly, but the application as a whole would have a slow start...

Is there other way, how to very quickly load an 10000 string array from a file?

UPDATE:
Why I need these strings? My Android app allows you to find "journeys" in Prague's public transit - you choose departure stop, arrival stop and it finds your journey (have a look here). My app has a suggestions feature - you enter leter "c" as your departure stop and a suggestions ListView appears with stops starting with "c". For these suggestions I need the strings. Fetching the suggestions from database is slow (about 400ms on G1).
