[android-developers] implicit intents
hallo i have made two applications A and B.A binds to a service of B
using an implicit intent:
intent i =new Intent (level1.level2);
Application B has a service that has an intent filter for actions of
type level1.level2.
The problem is that B is not always called.Sometimes it is called anad
everything works fine but some other times i get the following warning
in DDMS :
unable to start service Intent { act=level1.level2 } :not found
why is that??

[android-developers] Re: unable to bind to a service
well ok i understand the risk..and i will change the architecture
but anyway i have a problem to bind to a service of another apk even
if its attribute is exported=true
i wonder if i do someting wrong in my procedure:
in the remote apk i generate an interface from an aidl file and make a
service and with an anonymous class in it
that extends MyInterface.Stub.
In the client package i have an activity that has an object of type
MyInterface (that is the mservice object of type IGps in the example
above ) that i use it in order to call the methods exposed by my
remote service.However i don't have visibility of that interface since
it is in a remote package so i copy/paste the aidl from the remote
package into my client package and generate the interface as well ( i
also change the package name in the aidl file to that of my client
package) so now i have visibility of the ineterface..but this does not
seem to work ..do i make any mistake?

If you haven't declared an intent-filter in your manifest, then the
component will be private to that .apk. You can make it public with either
android:exported=true or defining an intent-filter.
HOWEVER.. PLEASE be super careful about doing this. Did you realize that
you are in the process of creating a nice big security hole, where you let
any application get the user's current location without needing permission?
Why are you doing this? The location APIs let applications get the current
location. Why are you republishing that information in your own service?
And why does this need to be in a separate .apk?
My first instinct is for you to just not do this. Please. If you really
think you need to do it, you need to seriously think about what you are
doing with security. You would be very much best off putting all of this
stuff in one .apk so you don't leak information to others. If for some
reason you really think you need to have this separate (and take the
overhead of multiple processes and all that), then you need to step back and
take serious consideration of security and applying permissions to enforce
it, how your .apks are signed, install ordering issues with granting
permissions, etc.

[android-developers] bind to a remore service
Hallo,
i have made an application that is consisted of an activity and a
service.The service has an interface (created by an aidl file)
including methods implemented in the service.My activity binds to the
service and calls some methods of the service.All good till now.My
problem is when i want to bind to a service that belongs to a
different package from my activity.My activity doesn't have visibility
of the remote interface and i cannot import it :
public class Client extends Activity {
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i=new Intent();
i.setComponent(new ComponentName(aexp.share.sharedapp3,
aexp.share.sharedapp3.Service_impl));
bindService(i, conn, Context.BIND_AUTO_CREATE);
}
ServiceConnection conn=new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName name) {
Log.e(TAG,DISCONNECTED);
}
@Override
public void onServiceConnected(ComponentName name, IBinder
service)
{
mservice=IGps.Stub.asInterface(service);

{
double a=mservice.getLat();
String a_str=Double.toString(a);
Log.e(TAG,a_str);
}
catch(RemoteException e)
{
}
}
};
}
Here i cannot see the IGps interface,Am i doing something wrong?

Uri contacts= Data.CONTENT_URI;
TextView phone=null;
Cursor cur = managedQuery(contacts, null, null, null, null);
if(cur.moveToFirst()) //if cur!=null
{
do {
phone=new TextView(this);
phone.setText(cur.getString(cur.getColumnIndex

setContentView(phone);

}
But instead of the phone the name of the contact is returned.I also
tried to get the email from my contact but it didn't show
anything.What i am doing wrong?

[android-developers] activity lifecycle
By default, pressing the BACK key finishes (destroys) the current activity and displays the previous activity to the user. I made and run an app and pressed the back key and returned to the main menu.However, when i typed the 'ps' command in the terminal emulator the process of my app was still there..My app constists only of this activity..shouldn't the process be killed? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] call an activity of another package
hallo,
i have an activity named SharedApp1 in the aexp.share.sharedapp1
package with the following simple code :
package aexp.share.sharedapp1;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class SharedApp1 extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
Button launchButton = new Button(this);
launchButton.setText(Launch);
setContentView(launchButton);
launchButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent i = new Intent();
i.setComponent(new ComponentName
(aexp.share.sharedapp1,aexp.share.sharedapp2.SharedApp2));
startActivity(i);
}
} );
}
}
I haven't modified its manifest file and i use an explicit intent in
order to call the activity SharedApp2 in the aexp.share.sharedapp2
package.But the application closes when i put the launch button (with
the relevant error message and the 'force close' button.Please help...

[android-developers] Re: call an activity of another package
oh mate you were right..just fixed this
i.setComponent(new ComponentName
(aexp.share.sharedapp2,aexp.share.sharedapp2.SharedApp2));
and it worked...thought that the first parameter was a reference to
the package we are in..

Looks like you are telling it that class SharedApp2 is in package
aexp.share.sharedapp1 - which is probably not correct.
Can you include the exception stack for the error in your post?

[android-developers] Re: ipc and user ids
well intents are a form of ipc ,right? when do we use binders for ipc and when intents? what are the plus and the cons?
