最近一直在做海外项目。涉及到推送功能。于是使用到了firebase.
firebase是Google推出的一个云端服务，并且它完全免费。
官方：https://firebase.google.com/features/ 。当然，由于是涉及海外的，所以，你懂的，要搬梯子。
firebase的功能有很多种，包含，推送通知，云存储，活动监视，远程部署等等。请注意：
手机中的Google Play Service的版本信息需要>=FireBase SDK的版本，否则FireBase将无效。
在firebase上可以看到用户weizhi位置：如下图（公司app）
同时你也可以使用FireBase进行LogEvent追踪，可以看到用户的偏好操作行为
具体代码：
public class Firebase {
private static Firebase instance;
private Context context;
private FirebaseAnalytics mFireInstance;
public Firebase(Context context) {
this.context = context;
}
public static Firebase getInstance(Context context) {
if (instance == null) {
instance = new Firebase(context);
}
return instance;
}
private FirebaseAnalytics getFirebaseAnalytics() {
if (mFireInstance == null) {
try {
mFireInstance = FirebaseAnalytics.getInstance(context);
} catch (Exception e) {
}
}
return mFireInstance;
}
public void logEvent(String category, String action) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putString("action", cutStringIfNecessary(action));
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, String action, String label) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putString(validateKey(action), cutStringIfNecessary(label));
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, String action, long value) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putLong(validateKey(action), value);
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, String action, double value) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putDouble(validateKey(action), value);
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, long value) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putLong("value", value);
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, double value) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
Bundle bundle = new Bundle();
bundle.putDouble("value", value);
firebaseAnalytics.logEvent(validateKey(category), bundle);
}
public void logEvent(String category, Bundle values) {
FirebaseAnalytics firebaseAnalytics = instance.getFirebaseAnalytics();
firebaseAnalytics.logEvent(validateKey(category), values);
}
private String cutStringIfNecessary(String v) {
if (!TextUtils.isEmpty(v) && v.length() > 100) {
return v.substring(0, 100);
}
return v;
}
private String validateKey(String key) {
if (!TextUtils.isEmpty(key)) {
if (!Character.isLetter(key.charAt(0))) {
key = "K" + key;
}
if (key.length() > 40) {
key = key.substring(0, 40);
}
for (int i = 0; i < key.length(); i++) {
if (!Character.isLetterOrDigit(key.charAt(i)) && key.charAt(i) != '_') {
key = key.replace(key.charAt(i), '_');
}
}
}
return key;
}
//设置是否开启数据收集功能
public void setAnalyticsCollectionEnabled(boolean enabled) {
instance.getFirebaseAnalytics().setAnalyticsCollectionEnabled(enabled);
}
public void setMinimumSessionDuration(long milliseconds) {
instance.getFirebaseAnalytics().setMinimumSessionDuration(milliseconds);
}
public void setUserId(String userId) {
instance.getFirebaseAnalytics().setUserId(userId);
}
public void setSessionTimeoutDuration(long milliseconds) {
instance.getFirebaseAnalytics().setSessionTimeoutDuration(milliseconds);
}
public void setUserProperty(String name, String value) {
instance.getFirebaseAnalytics().setUserProperty(name, value);
}
/*获取Appinsranceid 参数*/
public void getAppInstanceId(final getAppInstanceIdListener appInstanceIdListener) {
instance.getFirebaseAnalytics().getAppInstanceId().addOnCompleteListener(new OnCompleteListener<String>() {
@Override
public void onComplete(@NonNull Task<String> task) {
if (appInstanceIdListener != null) {
try {
appInstanceIdListener.setAppInstanceId(task.getResult());
} catch (RuntimeExecutionException e) {
appInstanceIdListener.setAppInstanceId("");
}
}
}
});
}
public interface getAppInstanceIdListener {
void setAppInstanceId(String appInstanceId);
}
在需要的时候，直接调用：Firebase.getInstance(getApplicationContext()).logEvent("xxx", "xxx");
使用Firebase进行推送。
首先需要再Firebase后台添加一个应用，然后下载Google-service.json文件，添加到应用中。如图
最后一步，运行项目，就可以看到firebase的统计了。
FireBase云推送是完全免费的，它的配置信息如下图所示：
其中打？是可选项。 值得注意的是下图：
1.需要使用两个service分别继承 ：FirebaseMessagingService和FirebaseInstanceIdService
FirebaseMessagingService
dataMap就是我们在Firebase云推送上配置的key-value的值。得到值后就可以进行相应的处理了
FirebaseInstanceIdService：
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
@Override
public void onCreate() {
super.onCreate();
FirebaseMessaging.getInstance().subscribeToTopic("xxx");
}
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
// [START refresh_token]
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// If you want to send messages to this application instance or
// manage this apps subscriptions on the server side, send the
// Instance ID token to your app server.
sendRegistrationToServer(refreshedToken);
}
// [END refresh_token]
/**
* Persist token to third-party servers.
* <p>
* Modify this method to associate the user's FCM InstanceID token with any server-side account
* maintained by your application.
*
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
// TODO: Implement this method to send token to your app server.
Log.e("id", token);
Log.e("id===========", token);
}
}
FirebaseMessaging.getInstance().subscribeToTopic("xxx") xxx这个值可以自定义，通过这个值可以在后台配置curl命令，然后在自己后台实现实时推送。
好了，关于推送就说到这了。下篇会讲到remoteConfig.谢谢！！
