Android :: Why Does App Signature Change In Android After Class Path Change?
Mar 16, 2010
I have an Android project that branched into three different applications, app-1, app-2 and app-3, that apply some customizations. Currently there is a lot of code duplication, making maintenance a nightmare: do the changes in one of the branches, and then merge the other two.So we create a library project, named app-core, that factors out most of the duplicated code. So far so good.When I launch this into an emulator where the application was already loaded (before the refactoring), I get this exception:Re-installation failed due to different application signatures.A different signature? But I just added a line in the .classpath to link to the app-core Java project!

Camera.setPreviewDisplay() now throws an IOException. Is there a reason this had to be a checked exception (looking at the source code I can't an see an immediate one)? Or is it just an oversight that will be fixed before releasing the final SDK? The consequence is that one cannot have code that will compile for both 1.1 and 1.5 without doing something ugly like adding a blanket try/catch.

Is there any way to change this in the android SDK?It looks like some of the .bat files in the ools folder sets some environment variables but cant tell exactly what they are doing.I set my windows system profile settings in the registry to point to d:users and everything else is pointing there but the android sdk keeps wanting to put things in c:users.My reasoning for this is I have a much faster drive as my d drive(5 disk raid0) and my system drive is a 5400 spin ide drive.

I have two questions:
1) how do I change the color of the seek bar (path) from yellow (the default color) to white. What I mean to say is, while I slide the thumb , it turns the line traversed from grey to yellow. I want track/line to either remain grey or white..Basically I want just the thumb to move with no color change in the seek bar.
2)
How to change the thumb of seekbar from rectangle to circle/sphere/round shape.

Pretty much self explanatory. When I use my taptalk account on my Eris, hero, and Droid it had that device in the signature but for some reason it has this weird device here.

I have installed the android sdk and the eclipse extensions for android development. My problem is that eclipse does not seem to know where to look for the android sdk. Is there an option in eclipse to manually tell it where it is?

I LOVE the K9 email app...but I would like to use the "different signatures for different accounts" feature. When I go into the "Message Composition Options" screen, I can edit the sig as much as I like, but there is no "Save Changes" button or option menu key just gives me the "No, you can't use this" haptic buzz. The Home key takes me back to my home screen.The back key takes me back to the general Account Settings screen - and discards my changes.

i would like to change the save path of my screenshots. The pictures i take with my camera automatically go to my external SD card, but not my screenshots for some reason.
My phone is a Note 3 if that matters.

Problem: I have one app that let's you lock the device using Device Administration. One of my users had some conflicts with my app and another. He then removed Device Administration and uninstalled my app, rebooted his phone, and now he cannot access his phone.
He of course cannot use my app to change the password now (since it's uninstalled).
His phone is stock 2.2 LG Optimus V, Virgin Mobile, Rooted.
Question:I'm needing to find a way that my user can now change his lock code.
I need:
1.) to know an internal class (from com.android.internal) that I could use within an app to change the lock code (just like the system settings do).
2.) to know a command I can use with adb shell to remove or change the phone lock code.
3.) to know the location of the file that stores the lock code information.

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

I have the following linear layout. What I don't understand is if I set the background to another image, the padding information are reset. Is there a way to prevent this?
<LinearLayout android:id="@+id/aPanel"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="@drawable/bkground"
android:paddingLeft="15dp" android:paddingRight="15dp">
<!-- some children here -->
</LinearLayout>
I see the position of the children get shifted when I change the backround drawable of the linearlayout 'aPanel'.

I have a widget which has say, a dimension of 294*72(portrait). But when the orientation is changed, I need to change this dimension of the widget to another dimension which would look good on the landscape orientation.

I'm using Eclipse to learn to develop Android applications in Java. I haven't used Eclipse before.The project I'm trying to use (supplied by OReilly as part of 'Android Application Development') is MJAndroid. When attempting to run the project, the Run fails, and the Problems tab mentions com.java.Object can't be found, and Eclipse asks me to check the build path. Clicking Properties -> Java Build Path -> Libraries, the message 'Unable to get system library for the project' is displayed.On a working project, Properties -> Java Build Path -> Libraries has an entry for Android 1.1, which if I click Edit, has the classpath container path of com.android.ide.eclipse.adt.ANDROID_FRAMEWORK.It seems a simple matter of adding the correct container path to my non-working project. However Eclipse seems determined to make this as difficult as possible. No matter what I chose to add - jars, externals jars, variables, libraries, class folders, external class folders, nothing seems to take the form of 'com.android.ide.eclipse.adt.ANDROID_FRAMEWORK' that the 'Android 1.1' entry on the working app has.

I need to create a Robotium application that would use Settings application to turn ON/OFF WIFi from menu Settings->Wireless & networks->Wi-Fi.I managed to find some sample code here that demonstrates how to launch application by having apk file only.The problem is that my Robotium application should have the same signature with the (system) Settings application.Can I somehow make it work with the Android Emulator?If I compile an Android phone image, how can I use the Android system signature with my application?

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

What I want to do, is be able to access the object neoApi inside the Neoseeker class, from its inner class RunningTimer. Now, in my code, you can see what I would think to work, but when I run my application, nothing pops up. Nothing inside my TextView, no Toast, nothing at all. How can I remedy this?
package com.neoseeker.android.app;
import java.util.Timer;
import java.util.TimerTask;
import org.json.JSONObject;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;

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:........................................
