Firebase Cloud Messaging 接收訊息 PHP Service

FCM兩種推播通知方式 - Notification與Data

----------------------------------FCM前置步驟可觀看----------------------------------
Step1:
https://litotom.com/2016/06/24/android-firebase-cloud-messaging-1/
注意:
apply plugin: 'com.google.gms.google-services'
要放在build.gradle(Module: app)這個檔案裡面的最下面

Step2:
https://litotom.com/2016/06/26/firebase-android-send-2/

-----------------------------------------------------------------------------------------------

1.在MyFirebaseMessagingService.java加入推播通知訊息

package com.terryyamg.fcmtest;

import android.app.Notification;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.NotificationManagerCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "MyFirebaseMessaging";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.i(TAG, "onMessageReceived:" + remoteMessage.getFrom());
        Intent intent = new Intent();   //點擊啟動到MainActivity頁面
        intent.setClass(this, MainActivity.class);
        showNotification(this, remoteMessage, intent);
    }

    // 顯示通知
    // remoteMessage.getData()         -  無論app在什麼狀態下皆會執行 MyFirebaseMessagingService(需對應Service設定的字串文字)
    // remoteMessage.getNotification() -  只會在app顯示時,執行app的接收訊息 MyFirebaseMessagingService
    private void showNotification(Context context, RemoteMessage remoteMessage, Intent intent) {
        NotificationManagerCompat manager = NotificationManagerCompat.from(this);
        PendingIntent iPending = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(remoteMessage.getData().get("title")) //需對應Service設定的字串文字
                        .setWhen(System.currentTimeMillis())
                        .setDefaults(Notification.DEFAULT_SOUND)
                        .setContentText(remoteMessage.getData().get("body")) //需對應Service設定的字串文字
                        .setContentIntent(iPending)
                        .setAutoCancel(true);

        Notification notification = mBuilder.build();
        manager.notify(1, notification);

    }
}

2.Service推播 fcm_service.php

    #API access key from Google API's Console
    define( 'API_ACCESS_KEY', 'AAAA6iG_xzk:APA91bHxlAkx5byr66cIFk-CXAr2k3hvs4tGQV9nAzj2nw75kPC8_9eIyyZVaeUPYFYzAk10qV-D0Pwl5BsIGslvv32PI2ECap1KcmW7Iu6lyzh1A3eEE2TJ5jVsnPydWFgKjvh3J5hh' );
    $registrationIds = "dTDs6rF7h04:APA91bECmREiN_qgUJ2IBwagJRzWmVxDMWVpmjEnkgJi1FWMLAtFHGTSYVXA-0VTHMf-42mZH8qLBEdKHFs9Z6oCL1JUf0uJ232z26XJdpEuwMvVPFxunwAZPN9E4-6qKImQEb7b9iHw";
    #prep the bundle
    $msg = array
    (
     'body'  => 'Body  Of Notification',
     'title' => 'Title Of Notification'
     );
    //'notification' - 只會在app顯示時,執行app的接收訊息Service
    //'data'         - 無論app在什麼狀態皆會執行app的接收訊息Service
    $fields = array
    (
     'to'  => $registrationIds,
     'data'     => $msg
     );
    
    
    $headers = array
    (
     'Authorization: key=' . API_ACCESS_KEY,
     'Content-Type: application/json'
     );
    #Send Reponse To FireBase Server
    $ch = curl_init();
    curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
    curl_setopt( $ch,CURLOPT_POST, true );
    curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
    curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
    curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
    $result = curl_exec($ch );
    curl_close( $ch );
    #Echo Result Of FireBase Server
    echo $result;

Android library Realm 資料庫

簡單的Realm資料庫CRUD應用

1.build.gradle(Project:xxxx)加入classpath "io.realm:realm-gradle-plugin:2.2.1"

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath "io.realm:realm-gradle-plugin:2.2.1"
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

2.build.gradle(Module:app)加入apply plugin: 'realm-android'

apply plugin: 'com.android.application'
apply plugin: 'realm-android'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"
    defaultConfig {
        applicationId "com.terryyamg.realmtest"
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    testCompile 'junit:junit:4.12'
}

3.AndroidManifest.xml的application內加入android:name=".MyApplication"

4.MyApplication.java

package com.terryyamg.realmtest;
import android.app.Application;
import io.realm.Realm;
public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        // Initialize Realm. Should only be done once when the application starts.
        Realm.init(this);

    }
}

5.MainActivity.java

import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

import io.realm.Realm;
import io.realm.RealmResults;

public class MainActivity extends AppCompatActivity {

    private Realm realm;
    TextView tvMessage;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        realm = Realm.getDefaultInstance();

        tvMessage = (TextView) findViewById(R.id.tvMessage);

        //Create
        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

Android Google Analytics V4 快速使用

使用Google Analytics來觀看app使用情形

1.先前往https://www.google.com/analytics/web/#home/
登入Google帳號，申請一個專案，就會得到一組序號
長這樣: UA-75136xxx-1

2.這裡IDE用Android studio，在build.gradle(Module:app)加入
compile 'com.google.android.gms:play-services-analytics:8.4.0'

3.建立一個app，在res資料夾下建立一個xml資料夾
建立app_tracker.xml檔案，位置/res/xml/app_tracker.xml


    
    300

    
    true

    
    UA-75136xxx-1

    100.0

    true

3.建立AnalyticsTrackers.java

package com.terryyamg.analyticstest;

import android.content.Context;

import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.Tracker;

import java.util.HashMap;
import java.util.Map;

/**
 * A collection of Google Analytics trackers. Fetch the tracker you need using
 * {@code AnalyticsTrackers.getInstance().get(...)}
 * <p/>
 * This code was generated by Android Studio but can be safely modified by
 * hand at this point.
 * <p/>
 * TODO: Call {@link #initialize(Context)} from an entry point in your app
 * before using this!
 */
public final class AnalyticsTrackers {

    public enum Target {
        APP,
        // Add more trackers here if you need, and update the code in #get(Target) below
    }

    private static AnalyticsTrackers sInstance;

    public static synchronized void initialize(Context context) {
        if (sInstance != null) {
            throw new IllegalStateException("Extra call to initialize analytics trackers");
        }

        sInstance = new AnalyticsTrackers(context);
    }

    public static synchronized AnalyticsTrackers getInstance() {
        if (sInstance == null) {
            throw new IllegalStateException("Call initialize() before getInstance()");
        }

        return sInstance;
    }

    private final Map<Target, Tracker> mTrackers = new HashMap<Target, Tracker>();
    private final Context mContext;

    /**
     * Don't instantiate directly - use {@link #getInstance()} instead.
     */
    private AnalyticsTrackers(Context context) {
        mContext = context.getApplicationContext();
    }

    public synchronized Tracker get(Target target) {
        if (!mTrackers.containsKey(target)) {
            Tracker tracker;
            switch (target) {
                case APP:
                    tracker = GoogleAnalytics.getInstance(mContext).newTracker(R.xml.app_tracker);
                    break;
                default:
                    throw new IllegalArgumentException("Unhandled analytics target " + target);
            }
            mTrackers.put(target, tracker);
        }

        return mTrackers.get(target);
    }
}

4.建立MyApplication.java

package com.terryyamg.analyticstest;

import android.app.Application;

import com.google.android.gms.analytics.GoogleAnalytics;
import com.google.android.gms.analytics.HitBuilders;
import com.google.android.gms.analytics.StandardExceptionParser;
import com.google.android.gms.analytics.Tracker;

public class MyApplication extends Application {
    public static final String TAG = MyApplication.class
            .getSimpleName();

    private static MyApplication mInstance;

    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;

        AnalyticsTrackers.initialize(this);
        AnalyticsTrackers.getInstance().get(AnalyticsTrackers.Target.APP);
    }

    public static synchronized MyApplication getInstance() {
        return mInstance;
    }

    public synchronized Tracker getGoogleAnalyticsTracker() {
        AnalyticsTrackers analyticsTrackers = AnalyticsTrackers.getInstance();
        return analyticsTrackers.get(AnalyticsTrackers.Target.APP);
    }

    /***
     * Tracking screen view
     *
     * @param screenName screen name to be displayed on GA dashboard
     */
    public void trackScreenView(String screenName) {
        Tracker t = getGoogleAnalyticsTracker();

        // Set screen name.
        t.setScreenName(screenName);

        // Send a screen view.
        t.send(new HitBuilders.ScreenViewBuilder().build());

        GoogleAnalytics.getInstance(this).dispatchLocalHits();
    }

    /***
     * Tracking exception
     *
     * @param e exception to be tracked
     */
    public void trackException(Exception e) {
        if (e != null) {
            Tracker t = getGoogleAnalyticsTracker();

            t.send(new HitBuilders.ExceptionBuilder()
                            .setDescription(
                                    new StandardExceptionParser(this, null)
                                            .getDescription(Thread.currentThread().getName(), e))
                            .setFatal(false)
                            .build()
            );
        }
    }

    /***
     * Tracking event
     *
     * @param category event category
     * @param action   action of the event
     * @param label    label
     */
    public void trackEvent(String category, String action, String label) {
        Tracker t = getGoogleAnalyticsTracker();

        // Build and send an Event.
        t.send(new HitBuilders.EventBuilder().setCategory(category).setAction(action).setLabel(label).build());
    }

}

5.修改AndroidManifest.xml 加入網路權限
android.permission.INTERNET
android.permission.ACCESS_NETWORK_STATE
在application加入android:name=".MyApplication"

6.基本上到這邊就完成了，可以在https://analytics.google.com/analytics/web/看到

7.加入異常或當機狀態，在/res/layout/activity_main.xml加個Button

8.MainActivity.java

package com.terryyamg.analyticstest;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btCrash = (Button) findViewById(R.id.btCrash);
        assert btCrash != null;
        btCrash.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try{
                    String name = null;
                    if (name.equals("test")){

                    }
                }catch (Exception e){
                    MyApplication.getInstance().trackException(e); //紀錄在Google Analytics裡
                    Log.i("NullPointerException",e+"");
                }
                //註解掉try catch會直接crash，也會紀錄在Google Analytics裡面
            }
        });
    }
}

當機與例外狀況要等約一天才會出現

其餘還有其他功用，可以參考http://www.androidhive.info/2015/08/android-integrating-google-analytics-v4/

    public DividerItemDecoration(Context context, int orientation) {
        final TypedArray a = context.obtainStyledAttributes(ATTRS);
        mDivider = a.getDrawable(0);
        a.recycle();
        setOrientation(orientation);
    }

    public void setOrientation(int orientation) {
        if (orientation != HORIZONTAL_LIST && orientation != VERTICAL_LIST) {
            throw new IllegalArgumentException("invalid orientation");
        }
        mOrientation = orientation;
    }

    @Override

        final int childCount = parent.getChildCount();
        for (int i = 0; i < childCount; i++) {
            final View child = parent.getChildAt(i);
            final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child
                    .getLayoutParams();
            final int top = child.getBottom() + params.bottomMargin;
            final int bottom = top + mDivider.getIntrinsicHeight();
            mDivider.setBounds(left, top, right, bottom);
            mDivider.draw(c);
        }
    }

    public void drawHorizontal(Canvas c, RecyclerView parent) {

        gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override

        MyAdapter adapter = new MyAdapter(ss);
        LinearLayoutManager lm = new LinearLayoutManager(this);
        rv.setLayoutManager(lm);
        rv.setHasFixedSize(true); //當RecyclerView大小沒改變時最佳化
        rv.setItemAnimator(new DefaultItemAnimator()); //預設動畫效果
        rv.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL)); //分隔線
        rv.setAdapter(adapter);

Android Splash Screen 新開啟畫面

前篇開啟app啟動畫面
http://terryyamg.blogspot.tw/2014/06/android-splashscreen.html
另一種方法

1.在 res/drawable/新增launch_screen.xml 上方加入android:opacity="opaque" 中間放入logo圖片並置中

2.在 res/values/styles.xml 新增一個AppTheme.Launcher

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.Launcher">
        <item name="android:windowBackground">@drawable/launch_screen</item>
    </style>

</resources>

3.在AndroidManifest.xml加入 android:theme="@style/AppTheme.Launcher"

4.最後MainActivity.java

package com.terryyamg.launchscreenstest;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setTheme(R.style.AppTheme); //加入此行
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

Android MVP 設計模式 Spinner練習

練習MVP設計模式，以Spinner為例
將檔案切成Model View Presenter

1.在Layout放置一個Spinner元件
2.View - MainActivity.java

package com.terryyamg.mvptest;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.Toast;

//View
public class MainActivity extends Activity implements MainActivityView {

    private Spinner spinner;
    private ArrayAdapter<String> listAdapter;

    private MainActivityPresenter presenter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinner = (Spinner) findViewById(R.id.spinner);

        presenter = new MainActivityPresenterImpl(this);
        presenter.guide(); //導向
    }

    //Override MainActivityView 設定Adapter
    @Override
    public void setAdapter(String[] data) {
        listAdapter = new ArrayAdapter<>(this,
                android.R.layout.simple_spinner_item, data);
        listAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    }

    //Override MainActivityView 設定Spinner動作
    @Override
    public void setSpinner(final String[] data) {
        spinner.setAdapter(listAdapter);
        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                                       int pos1, long arg3) {
                Toast.makeText(MainActivity.this, data[pos1], Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {

            }
        });
    }
}

3.View - MainActivityView.java

package com.terryyamg.mvptest;

public interface MainActivityView {

    void setAdapter(String[] data);

    void setSpinner(String[] data);

}

4.Presenter - MainActivityPresenter.java

package com.terryyamg.mvptest;

public interface MainActivityPresenter {

    void guide();

}

5.Presenter - MainActivityPresenterImpl.java

package com.terryyamg.mvptest;

//Presenter
public class MainActivityPresenterImpl implements MainActivityPresenter {

    private MainActivityView mView;
    private MainActivityModel mModel;

    public MainActivityPresenterImpl(MainActivityView mView) {
        this.mView = mView;
        this.mModel = new MainActivityModelImpl();
    }


    @Override
    public void guide() {
        mModel.setData(mView); //導向Model
    }
}

6.Model - MainActivityModel.java

package com.terryyamg.mvptest;

public interface MainActivityModel {

    void setData(MainActivityView view);

}

7.Model - MainActivityModelImpl.java

package com.terryyamg.mvptest;

//Model
public class MainActivityModelImpl implements MainActivityModel {

    @Override
    public void setData(MainActivityView view) {
        String[] data = {"A", "B", "C", "D", "E"};

        //放入資訊
        view.setAdapter(data);
        view.setSpinner(data);
    }
}

完成後就可以得到一個與一般的spinner相同的效果
