目前Android应用在后台杀死进程之后,就收不到通知了,想要接收消息推送,需要集成各个厂商的推送SDK,以小米为例。
1.1 登录小米开发者网站(
https://dev.mi.com/console/appservice/),创建App并获取AppId,AppKey和AppSecret。
1.2 下载Android客户端SDK压缩包。
下载地址:
http://dev.xiaomi.com/mipush/downpage/ 。
压缩包中包含了Server SDK、Client SDK和android DEMO。
2.1 配置AndroidManifest.xml文件
小米推送服务SDK支持的最低安卓版本为2.3。
<uses-sdk android:minSdkVersion="9"/>
推送服务需要的权限列表:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.VIBRATE"/>
<permission android:name="com.xiaomi.mipushdemo.permission.MIPUSH_RECEIVE" android:protectionLevel="signature" /> <!--这里com.xiaomi.mipushdemo改成app的包名-->
<uses-permission android:name="com.xiaomi.mipushdemo.permission.MIPUSH_RECEIVE" /><!--这里com.xiaomi.mipushdemo改成app的包名-->
推送服务需要配置的service和receiver:
<service
android:name="com.xiaomi.push.service.XMPushService"
android:enabled="true"
android:process=":pushservice" />
<!--注:此service必须在3.0.1版本以后(包括3.0.1版本)加入-->
<service
android:name="com.xiaomi.push.service.XMJobService"
android:enabled="true"
android:exported="false"
android:permission="android.permission.BIND_JOB_SERVICE"
android:process=":pushservice" />
<service
android:name="com.xiaomi.mipush.sdk.PushMessageHandler"
android:enabled="true"
android:exported="true" />
<!--注:此service必须在2.2.5版本以后(包括2.2.5版本)加入-->
<service
android:name="com.xiaomi.mipush.sdk.MessageHandleService"
android:enabled="true" />
<receiver
android:name="com.xiaomi.push.service.receivers.NetworkStatusReceiver"
android:exported="true">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<receiver
android:name="com.xiaomi.push.service.receivers.PingReceiver"
android:exported="false"
android:process=":pushservice">
<intent-filter>
<action android:name="com.xiaomi.push.PING_TIMER" />
</intent-filter>
</receiver>
这里将XMPushService和PingReceiver定义在了pushservice进程中,您也可以配置其运行在任意进程。如果没有配置android:process这个属性,那么它们将运行在应用的主进程中。
2.2 自定义一个BroadcastReceiver类
为了接收消息,您需要自定义一个继承自PushMessageReceiver类的BroadcastReceiver
public class DemoMessageReceiver extends PushMessageReceiver {
private String mRegId;
private long mResultCode = -1;
private String mReason;
private String mCommand;
private String mMessage;
private String mTopic;
private String mAlias;
private String mUserAccount;
private String mStartTime;
private String mEndTime;
@Override
public void onReceivePassThroughMessage(Context context, MiPushMessage message) {
mMessage = message.getContent();
if(!TextUtils.isEmpty(message.getTopic())) {
mTopic=message.getTopic();
} else if(!TextUtils.isEmpty(message.getAlias())) {
mAlias=message.getAlias();
} else if(!TextUtils.isEmpty(message.getUserAccount())) {
mUserAccount=message.getUserAccount();
}
}
@Override
public void onNotificationMessageClicked(Context context, MiPushMessage message) {
mMessage = message.getContent();
if(!TextUtils.isEmpty(message.getTopic())) {
mTopic=message.getTopic();
} else if(!TextUtils.isEmpty(message.getAlias())) {
mAlias=message.getAlias();
} else if(!TextUtils.isEmpty(message.getUserAccount())) {
mUserAccount=message.getUserAccount();
}
}
@Override
public void onNotificationMessageArrived(Context context, MiPushMessage message) {
mMessage = message.getContent();
if(!TextUtils.isEmpty(message.getTopic())) {
mTopic=message.getTopic();
} else if(!TextUtils.isEmpty(message.getAlias())) {
mAlias=message.getAlias();
} else if(!TextUtils.isEmpty(message.getUserAccount())) {
mUserAccount=message.getUserAccount();
}
}
@Override
public void onCommandResult(Context context, MiPushCommandMessage message) {
String command = message.getCommand();
List<String> arguments = message.getCommandArguments();
String cmdArg1 = ((arguments != null && arguments.size() > 0) ? arguments.get(0) : null);
String cmdArg2 = ((arguments != null && arguments.size() > 1) ? arguments.get(1) : null);
if (MiPushClient.COMMAND_REGISTER.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mRegId = cmdArg1;
}
} else if (MiPushClient.COMMAND_SET_ALIAS.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mAlias = cmdArg1;
}
} else if (MiPushClient.COMMAND_UNSET_ALIAS.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mAlias = cmdArg1;
}
} else if (MiPushClient.COMMAND_SUBSCRIBE_TOPIC.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mTopic = cmdArg1;
}
} else if (MiPushClient.COMMAND_UNSUBSCRIBE_TOPIC.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mTopic = cmdArg1;
}
} else if (MiPushClient.COMMAND_SET_ACCEPT_TIME.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mStartTime = cmdArg1;
mEndTime = cmdArg2;
}
}
}
@Override
public void onReceiveRegisterResult(Context context, MiPushCommandMessage message) {
String command = message.getCommand();
List<String> arguments = message.getCommandArguments();
String cmdArg1 = ((arguments != null && arguments.size() > 0) ? arguments.get(0) : null);
String cmdArg2 = ((arguments != null && arguments.size() > 1) ? arguments.get(1) : null);
if (MiPushClient.COMMAND_REGISTER.equals(command)) {
if (message.getResultCode() == ErrorCode.SUCCESS) {
mRegId = cmdArg1;
}
}
}
}
将自定义的BroadcastReceiver注册到AndroidManifest.xml文件中
<receiver
android:exported="true"
android:name="com.xiaomi.mipushdemo.DemoMessageReceiver">
<!--这里com.xiaomi.mipushdemo.DemoMessageRreceiver改成app中定义的完整类名-->
<intent-filter>
<action android:name="com.xiaomi.mipush.RECEIVE_MESSAGE" />
</intent-filter>
<intent-filter>
<action android:name="com.xiaomi.mipush.MESSAGE_ARRIVED" />
</intent-filter>
<intent-filter>
<action android:name="com.xiaomi.mipush.ERROR" />
</intent-filter>
</receiver>
2.3 注册推送服务
通过调用MiPushClient.registerPush来初始化小米推送服务。注册成功后,您可以在自定义的onCommandResult和onReceiveRegisterResult中收到注册结果,其中的regId即是当前设备上当前app的唯一标示。您可以将regId上传到自己的服务器,方便向其发消息。
为了提高push的注册率,您可以在Application的onCreate中初始化push。您也可以根据需要,在其他地方初始化push。 代码如下:
public class DemoApplication extends Application {
public static final String APP_ID = "your appid";
public static final String APP_KEY = "your appkey";
public static final String TAG = "your packagename";
@Override
public void onCreate() {
super.onCreate();
//初始化push推送服务
if(shouldInit()) {
MiPushClient.registerPush(this, APP_ID, APP_KEY);
}
//打开Log
LoggerInterface newLogger = new LoggerInterface() {
@Override
public void setTag(String tag) {
// ignore
}
@Override
public void log(String content, Throwable t) {
Log.d(TAG, content, t);
}
@Override
public void log(String content) {
Log.d(TAG, content);
}
};
Logger.setLogger(this, newLogger);
}
private boolean shouldInit() {
ActivityManager am = ((ActivityManager) getSystemService(Context.ACTIVITY_SERVICE));
List<RunningAppProcessInfo> processInfos = am.getRunningAppProcesses();
String mainProcessName = getApplicationInfo().processName;
int myPid = Process.myPid();
for (RunningAppProcessInfo info : processInfos) {
if (info.pid == myPid && mainProcessName.equals(info.processName)) {
return true;
}
}
return false;
}
}
3.1 创建推送
3.2 填写推送内容
把应用在后台关闭掉,点击推送,仍可以收到推送通知,就说明集成成功了。
