[Android][Resolved] import android.support.design.widget.floatingactionbutton not found

Problem

import android.support.design.widget.FloatingActionButton
Unresolved reference :  design

Solve

Step 1)
Open your build.grade in app level.

Step 2)
Add this lines into dependencies :

compile 'com.android.support:design:25.3.1'

The text in red better if same with your version number of com.android.support:appcompat, for my case, it's com.android.support:appcompat-v7:25.3.1, so i use com.android.support:design:25.3.1.

Step 3)

After edited the file, don't forget to click Sync Now at top-right corner.

Source code

Finally found the problem is not much related to the error message: "You need to use a Theme.AppCompat theme (or descendant) with this activity". My case isn't related to adding sth like android:theme="@style/Theme.AppCompat in AndroidManifest.xml suggested from internet exiting case answer.

Do not use getApplicationContext() to get application context for AlertDialog constructor, use this keyword to use activity context :

new AlertDialog.Builder(getApplicationContext())

         .setTitle("Developer")

         .setMessage("Hello")

         .show();

use "this" instead:

new AlertDialog.Builder(this)

         .setTitle("Developer")

         .setMessage("Hello")

         .show(); 

For  further reading, you can click to read the different between application context and activity context: What is different between MainActivity.this vs getApplicationContext()

[Android][Resolved] Android device offline in android studio with windows platform

Version

• Android Studio 2.2.3
• Windows 8

Step 1

If your android device is detected but shows offline, you should disconnect your connection to your computer first (Either it's via USB or Wi-Fi)

Step 2 

Close Android Studio.

Step 3

Kill ALL adb.exe processes.
(For example, Press "CTRL"+"ALT"+"DELETE" and then select Task Manager, right click adb.exe and select "End task".)

Step 4

Restart Android Studio

Step5

Restart your Android device and connect it to your computer via USB or wifi. (I use USB cable).

[Android][Win8][Resolved] 'adb' is not recognized as an internal or external command, operable program or batch file in windows7 platform

Error message:

'adb' is not recognized as an internal or external command, operable program or batch file.

Thing you had to do is add the Sdk and platform tool of Android to your environment value.

Step1

Look out your Sdk and platform tool of Android first and copy the location. For my case, Android 2.2.2 in windows 8 is located here:

C:\Users\xenialaw\AppData\Local\Android\sdk\platform-tools

Step2

Right click the This PC and select "properties". (In windows 7)

Step3

Select "advanced system settings"

Step4

Click "Environment Variables" button

Step5

Add the location path you copied to the end of Variables value, and then add a semicolon after that.

C:\Users\xxxx\AppData\Local\Android\sdk\platform-tools;

Step6
Restart your android studio or command prompt.

Edit the text in orange to filename you like and the text in green to the location you want save the keystore file.

[Android][php] Example code for using okhttp to send post repuest and get response from a php webpage

Step1 - Add okhttp as dependencies in yout project

Firstly, you needed to add dependencies your build.gradle in your module and check "Sync Now" next to the line "Gradle files have changed since last project sync. A project sync may be neccessary for the IDE to work properly." with yellow background.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.squareup.okhttp3:okhttp:3.2.0'
}

Step 2 - Create php file

Create a php file named "test.php", for my case i placed it at C:\xampp\htdocs\fcm in windows platform.

<?php
echo "Hello World : ";
if(isset($_POST['test'])) echo $_POST['test'];
?>

Step 3 - Make request and get feedback in your android project

Make request in AsyncTask or Thread, to make it looks simple i put that in a Thread (but using Thread in android may not is the good practice).

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

import java.io.IOException;

import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class MainActivity extends AppCompatActivity {

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

        Thread t = new Thread(new Runnable(){
            @Override
            public void run() {
                OkHttpClient client = new OkHttpClient();
                RequestBody body = new FormBody.Builder()
                        .add("test","HAHA")
                        .build(); //Create request body

                Request request = new Request.Builder()
                        .url("http://192.168.232.45/fcm/test.php")
                        .post(body)
                        .build(); //create request

                try {
                    //Send request and save response
                    Response response = client.newCall(request).execute();
                    //Show response
                    Log.d("dump","dump:"+response.body().string());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });
        t.start();
    }
}

[Android][Resolved] remoteMessage.getData().get("message") return null

Source code

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService{
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        showNotification("null:"+remoteMessage.getData().get("message"));
    }

    private void showNotification(String message) {
        Intent i = new Intent(this,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setAutoCancel(true)
                .setContentTitle("FCM Test")
                .setContentText(message)
                .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
                .setContentIntent(pendingIntent);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(0,builder.build());
    }
}

If you get this situation, you can check is the sentence remoteMessage.getData().get("message") return null first, if that's null then use other syntax to get the notification message :

if (remoteMessage.getData().get("message") != null) {
        showNotification( remoteMessage.getData().get("message") );
} else if((remoteMessage.getNotification().getBody() != null)) {
        showNotification( remoteMessage.getNotification().getBody() );
} else {
        Log.d("FCM error","Can receive message but can't get content from FCM");
}

Since keytool is an application provided with standard Java Development Kit (JDK), you should look for it at your Java Home where installed your JDK, for my case, my keytool is installed here:

You can use that application in command prompt in to generate Certificate fingerprints for development.

So first you could do is click "file"-> "Invalidate Caches / Restart" to clear invalidate Caches in your android studion and the restart automatically.

After restarted android studio, you are still not able to run Android Virtual Device, let look for any update available for your android studio:

For my case, i updated my Android studio to latest version 2.2.2, ran Android Virtual Device (AVD) for the project and it's not work again, just follow the instruction to download the missing system image :

And finally it works .

According to samtstern in github.com, trying to update your dependency from compile 'com.google.firebase:firebase-messaging:9.0.0' to compile 'com.google.firebase:firebase-messaging:9.0.2' can fix this. And i tried it works like a claim:

my module/build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.firebase.pushnotification"
        minSdkVersion 19
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.1.1'

    apply plugin: 'eclipse'
    //compile 'com.google.firebase:firebase-messaging:9.0.0'
    compile 'com.google.firebase:firebase-messaging:9.0.2'
    compile 'com.squareup.okhttp3:okhttp:3.2.0'
}

apply plugin: 'com.google.gms.google-services'

Other files in my testing project for your reference:
my project/build.gradle

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.google.gms:google-services:3.0.0'
        // 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
}
