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 'oem.android.proj1.IRemoteService' but read

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
