Is there any way to expose the methods of one application to another application in android. Suppose that I have written a slider for one application and if i want to use the same slider in some other application, How can I do it without copying the source.(Both the applications are installed on the device).

I have created a service and want to expose the interface to other applications. For one service I have done this successfuly. I just put the AIDL interface into the new project and all worked fine. Now for this service I've done the same but I get a java.lang.VerifyError when trying to use this interface. I think that the problem is that the AIDL uses a class (PolicyRole) that is only defined in the source code of the service. To compile the source that uses the interface I had to link against the code of the service but at runtime the error appears. Code...
View 2 Replies View RelatedNeed 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 am currently working on porting a application written in C in android platform. I need to know that can i invoke/call the getSystemService from the C application using invocation interface by JNI. Meaning using a .java file which will interact with the interace provided by the android.telephony.TelephonyManager.java for using getCallState() and other mehthods.
View 2 Replies View RelatedI 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:

View 1 Replies View RelatedI want to add a big feature to an application i am developping, but as this feature interest few people and is quite independant from the main part, I would like to put that in a seperate "plugin" application.Does anyone knows any design patterns, snippets, "reference" examples about such design?In particular that separate plugin application should be able to access some tables in the main application DB. Is it possible to do that without broadcast receiver? - the main application uses a TabActivity: is it possible that a the tabactivity instanciates an Intent Activity that is part of the plugin? - does the plugin can access main application preferences (not sure this would be necessary, but better to anticipate the question!) is it possible from the plugin to access main applications ressources?At least the 2 first points are mandatory for me.

View 1 Replies View RelatedI guess that Android won't let people to do this, because they think they have perfect handle for the task/applications. However, I really need to do this in my case.
I have an activity A acting as the entry point of my application. In that activity, it reads the preference and decided which activity to start, say B or C. After that, it finishes itself. So, activity A never appears to the users.
My application stores things on sdcard, and reads from it constantly. So, when the sdcard is unmounted, I need to display a message to the user that the sdcard is unavailable, instead of opening B or C. I set a check in A to display that message when sdcard is unavilable. When that message is displayed, A will not try to start B or C.
Things works perfectly if user only enter my application from application launcher. However, I found that user can also enter my application by long pressing home and choose it from the recent application list, if he has opened it recently. When user does that, it skips A and goes directly to B or C. I don't have the check in both of them, so exception is thrown while I am trying to access sdcard, and force close dialog pops up.
I can simply move my check to both B and C to fix this problem. But in the future, the number of activities started from A will increase. If there are 6 of them, I'll need to copy this check to 6 places. Needless to say, this looks very ugly, and is a maintenance nightmare.
So, the best fix should be removing my application from recent application list when the sdcard is uunmounted. However, I can't find how to do this. Even killing the process or use ActivityManager.restartPackage, it still appears in the list. Can anyone tell me how to remove it from the list?

Is there any way to hide an application icon from Android applications list ? The application should be downloaded from Market and opened some GUI for configuring my application. I don't want to see any icon of my application in applications list. User should not be able to run it.
By the way I know some way:
remove this line from manifest
<category android:name="android.intent.category.LAUNCHER" />
But it is not worked for me, because the GUI is not shown.

I have published application and now I'm making update to it. I changed applications Data structure and moved all files under /Android/ data/<package_name>/files/ folder.All files that are in that folder will be automatically removed when application is uninstalled.I want those files to be removed when application is uninstalled but not when it's UPDATED. I don't want users to lose all their data after every update. I don't know how to test it (without publishing new release). So will those files be deleted when user updates my application?

I would like to know if it is possible to launch my application whenever a new entry is written to phone call log (i.e. out-going, in-coming or missed call). I wrote an application to manage the call log entries as per user preferences by listening to the publication of android.intent.action.PHONE_STATE events. My application is working fine as long as its process is running. However if the user has stopped my application with a task-killer application, then the log entries can not be managed as my app itself was not running. I need a way to make sure that my application is launched in the background if it is not already running when the android.intent.action.PHONE_STATE occurs. Or is it possible to launch my application as a service that always runs?
