前些天想着给istkani在Android集成个push notification，用了腾讯的信鸽，结果在进程退出后老是会弹框说进程意外结束云云，于是就放下了。
后来又偶然地看了一下LeanCloud，发现LeanCloud也是提供push服务的，于是就想再试试，顺便把它的其他能用上的功能都加上试试，于是就要集成它的iOS和Android的SDK，说干就干，现在终于初步已经完成了。
集成到Qt for iOS上相对来说要容易一些。
首先，自己重载一下QIOSApplicationDelegate：
#import <AVOSCloud/AVOSCloud.h>
@implementation QIOSApplicationDelegate (istkaniAppDelegate)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
[application setMinimumBackgroundFetchInterval:UIApplicationBackgroundFetchIntervalMinimum];
//[application setMinimumBackgroundFetchInterval:minimumBackgroundFetchInterval];
}
// register for push notification
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert
| UIUserNotificationTypeBadge
| UIUserNotificationTypeSound
categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
}else{
[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert
| UIRemoteNotificationTypeSound
| UIRemoteNotificationTypeBadge)];
}
// launched by push notification
NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
NSLog(@"Remote notification payload at startup: %@", userInfo);
[application setApplicationIconBadgeNumber:0];
// leancloud initialize
[AVOSCloud setApplicationId:@"xxxxxxxxxxxxxxxxxxxxxxxxxxx"
clientKey:@"yyyyyyyyyyyyyyyyyyyyyyyy"];
[AVAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
return YES;
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
// register in leancloud
AVInstallation *currentInstallation = [AVInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
[currentInstallation addUniqueObject:@"public" forKey:@"channels"];
[currentInstallation saveInBackground];
}
然后，在qmake file里加上对LeanCloud SDK的链接：

ios {
INCLUDEPATH += $$PWD/ios
HEADERS += \
$$PWD/ios/QtAppDelegate.h \
$$PWD/ios/QtAppDelegate-C-Interface.h
OBJECTIVE_SOURCES += \
$$PWD/ios/QtAppDelegate.mm
QMAKE_LFLAGS += -F$$PWD/avoscloud-ios-sdk-v3.1.1.1
LIBS += -framework CFNetwork \
-framework AVOSCloud \
-framework AVOSCloudCrashReporting \
-framework AVOSCloudIM \
-framework AVOSCloudSNS \
-framework MobileCoreServices \
-framework CoreTelephony \
-framework CoreLocation \
-licucore -lc++ -lz
}
这样就基本上搞定了。
在Android上集成稍微麻烦一点。我主要是要加入push notification，所以就冲着这个目标去了。
首先，重载Application类的onCreate方法：

package com.dfordsoft.istkani;
import android.app.Application;
import org.qtproject.qt5.android.bindings.QtApplication;
import android.util.Log;
import com.avos.avoscloud.*;
public class IstkaniApp extends QtApplication {
private final static String TAG = "istkani";
@Override
public void onCreate() {
super.onCreate();
AVOSCloud.initialize(this,
"xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"yyyyyyyyyyyyyyyyyyyyyyyyyyyy");
// 设置默认打开的 Activity，注意，这里我把activity也派生了
PushService.setDefaultPushCallback(this, QtPushActivity.class);
// 订阅频道，当该频道消息到来的时候，打开对应的 Activity
PushService.subscribe(this, "public", QtPushActivity.class);
AVInstallation.getCurrentInstallation().saveInBackground(new SaveCallback() {
public void done(AVException e) {
if (e == null) {
// 保存成功
String installationId = AVInstallation.getCurrentInstallation().getInstallationId();
// 关联 installationId 到用户表等操作……
Log.d(TAG, "saved installation id:" + installationId);
} else {
// 保存失败，输出错误信息
Log.w(TAG, "saving installation id failed");
}
AVInstallation.getCurrentInstallation().saveInBackground();
}
});
// 启用崩溃错误统计
AVAnalytics.enableCrashReport(this.getApplicationContext(), true);
AVOSCloud.setDebugLogEnabled(true);
}
}
另外，可以从默认的Activity类再派生一个类来做些其他事：

package com.dfordsoft.istkani;
import org.qtproject.qt5.android.bindings.QtActivity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.avos.avoscloud.*;
public class QtPushActivity extends QtActivity {
private final static String TAG = "istkani";
@Override
protected void onDestroy() {
super.onDestroy();
Log.d(TAG, "on destroy");
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG, "on create");
AVAnalytics.trackAppOpened(getIntent());
}
protected void onPause() {
super.onPause();
AVAnalytics.onPause(this);
}
protected void onResume() {
super.onResume();
AVAnalytics.onResume(this);
}
}
因为我的app包名是com.dfordsoft.istkani，所以这些Java源代码文件是要放在$(PROJECT)/android/src/com/dfordsoft/istkani/目录下的。把LeanCloud SDK中的那些jar文件放在$(PROJECT)/android/libs目录下。
然后修改qmake file：

android: {
QT += androidextras
ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android

DISTFILES += \
$$PWD/android/src/com/dfordsoft/istkani/QtPushActivity.java \
$$PWD/android/src/com/dfordsoft/istkani/IstkaniApp.java
}
最后修改AndroidManifest.xml文件：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.READ_LOGS" />
这里为了让排版不那么乱，有一大堆meta-data节点没列出来，要改的是application节点的android:name属性是自己派生的IstkaniApp类，activity节点的android:name属性是自己派生的QtPushActivity类。另外就是加上必要的service节点，receiver节点和一些app必须的权限。
我试着加了其他的AVDefaultNotificationReceiver和自定义Receiver，结果在网络连接状态变化时，或者不能连网时，或者干脆在3G连接时，就会弹框报错，不知道信鸽是不是就是这个原因，我不也想再多追究了，好在这样就能正常收到push notification了。
感觉本文不错，不妨小额鼓励我一下！
