I define a class Rect and a aidl file as below:
Rect.java:
package linda.test;
import android.os.Parcel;
import android.os.Parcelable;
public class Rect implements Parcelable {
public int left;
public int top;
public int right;
public int bottom;
public static final Parcelable.Creator<Rect> CREATOR = new
Parcelable.Creator<Rect>() {
public Rect createFromParcel(Parcel in) {
return new Rect(in);
}
public Rect[] newArray(int size) {
return new Rect[size];
}
};
public Rect() {
}
private Rect(Parcel in) {
readFromParcel(in);
}
public int getTop(){
return top;
}
public void writeToParcel(Parcel out, int i) {
out.writeInt(left);
out.writeInt(top);
out.writeInt(right);
out.writeInt(bottom);
}
public void readFromParcel(Parcel in) {
left = in.readInt();
top = in.readInt();
right = in.readInt();
bottom = in.readInt();
}
public int describeContents (){
return 0;
}
}
Rect.aidl
package linda.test;
import android.os.Parcel;
import android.os.Parcelable;
parcelable Rect;
And then i create a service and aidl file as below:
MyService.java
package linda.test;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.IBinder;
import android.util.Log;
import android.content.ContentResolver;
import android.app.Activity;
import android.content.IntentFilter;
import java.io.*;
import java.util.*;
import android.os.Parcel;
import linda.test.Rest;
public class MyService extends Service {
public MyService(){
mService = this;
}
public static void startService(final Context context){
if (mService != null)
return;
context.startService(new Intent(context, MyService.class));
return;
}
public static void stopService(final Context context){
if (mService == null)
return;
context.stopService(new Intent(context, MyService.class));
return;
}
@Override
public IBinder onBind(Intent intent) {
if (IMyService.class.getName().equals(intent.getAction())){
return mBinder;
}else if (false){
}
return null;
}
/*
* Public service interfaces
*/
private final IMyService.Stub mBinder = new IMyService.Stub(){
public Rect testSetRect(int a, int b, int c, int d){
Rect rect = new Rect();
rect.left = a;
rect.right = b;
rect.top = c;
rect.bottom = d;
return rect;
}
};
@Override
public void onCreate(){
super.onCreate();
}
@Override
public void onDestroy(){
super.onDestroy();
}
}
IMyService.aidl:
interface IMyService{
Rect testSetRect(int a, int b, int c, int d);
}
and there is an activity "AidlTest" will call function "Rect
testSetRect(int a, int b, int c, int d); ", so i copy Rect.aidl and
IMyService.aidl file to the acitivty folder, add IMyService.aidl path
in Android.mk, then build AidlTest, the following error happens:
