Hi All,
When my client code calls bindService it was fine and it calls
onServiceConnected, there i am calling the interface method using the
XXXX.Stub.asInterface(service) object and there only it gives me bunch of
error as:
02-13 17:14:52.239: WARN/Parcel(1035): **** enforceInterface() expected

My Server and Client code both are in different package i mean in
different .APK.
I have ran the Service code first and these are the below files i am
using:
IRemoteService.aidl -> have the interfaces
DisplayPage.java --> Activity that starts the RemoteService.java
RemoteService.java --> Service and impliments the interface methods
AndroidManifest.xml code:
<application android:icon="@drawable/icon" android:label=
"@string/app_name">
<activity android:name=".DisplayPage" android:label=
"@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"
/>
</intent-filter> </activity>
<service android:name="RemoteService" android:exported="true"
class="RemoteService" android:process=":remote">
<intent-filter>
<action android:name="oem.android.proj2.IRemoteService"/>
<action android:name="oem.android.proj2.REMOTE_SERVICE"/>
</intent-filter> </service>
</application>
IRemoteService.aidl code:
package oem.android.proj1;
interface IRemoteService{
void display();
RemoteService.java code:
package oem.android.proj1;
public class RemoteService extends Service {
public void onCreate() {
super.onCreate(); }
public IBinder onBind(Intent intent) {
If (IRemoteService.class
.getName().equals(intent.getAction())){
return mBinder; }
return mBinder;}}
private final IRemoteService.Stub mBinder = new IRemoteService.Stub(){
public void display(){
Toast.makeText(RemoteService.this, "RemoteService --
display function",
Toast.LENGTH_SHORT).show(); }
};}
Then i ran the Client code and these are the below files i am using:
IRemoteService.aidl -> have the interfaces
RemoteServiceBinding.java --> Activity that that calls the bindService and
calls the Service's methods.
AndroidManifest.xml code:
<application android:icon="@drawable/icon" android:label=
"@string/app_name">
<activity android:name=".RemoteServiceBinding"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER"
/>
<action android:name="oem.android.proj1.IRemoteService"/>
<action android:name="oem.android
.proj1.IRemoteService.display"/>
</intent-filter>
</activity>
IRemoteService.aidl code:
package oem.android.proj1;
interface IRemoteService{
void display();
RemoteServiceBinding.java code:
package oem.android.proj2;
public class RemoteServiceBinding extends ListActivity {
private Context ctx;
IRemoteService mService = null;
private String[] mStrings = {"Bind", "Conn"};
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
XXXXXXXXX}
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className,IBinder
service) {
mService = IRemoteService.Stub.asInterface(service);
}
public void onServiceDisconnected(ComponentName name) {
mService = null;}
};
protected void onListItemClick(ListView l, View v, int position, long id)
{
if(position ==0)
{
bindService(new Intent(IRemoteService.class
.getName()),
mConnection, Context.BIND_AUTO_CREATE);
}
if(position ==1)
{
try {
mService.display();
} catch (RemoteException e) {
// TODO Auto-generated
catch block
e.printStackTrace();
} }
}
i have set the ListItem listener when i press my bind one it should call
the bindService and it is doing correctly, but when i click the Conn it
should call my display() method but is giving me errors that i have
mentioned on the top.
Can someone plz help me what went wrong on my code, i am assuming that
some thing broken in my AndroidManifest.xml code only.
Actually i am still in dilema what all thing to set in AndroidManifest.xml
file in both Client and Server site, like permisson or any other things.
Thanks & Regards,
Sunil

Client-Server project

That's what the error is, I'm simply calling start service like this:
if( null == startService( new Intent( this, TestService.class ) ) )
{
if( null != in_oOutput )
{
in_oOutput.append( "\nstartService
returned 'null'" );
}
return false;
}
My client class has imported TestService via:
import com.android.TestService.*;
So, I'm wondering why, unless I declare the service in the client's
manifest as I explained before (and change absolutely nothing else)
does it work just fine, but without the service line in the client
manifest it is trying, for some reason, to find it in the wrong place.
When it works, the activity manager reports in the log:
"02-12 15:08:43.541: INFO/ActivityManager(50): Start proc
com.android.servicemonitor:remote for service
com.android.servicemonitor/com.android.TestService.TestService:
pid=621 uid=10018 gids={}"
So it would seem that com.android.servicemonitor/
com.android.TestService.TestService is perfectly fine.
