August(?) 2017:

We’re thrilled to announce the Runnable team is joining MuleSoft. This is an incredible opportunity for us to expand our vision of empowering developers to test changes without the infrastructure bottleneck; we couldn’t be more excited to work with MuleSoft to continue our journey.

As apart of this transition, we’re shutting down service for all Runnable accounts. To those we had the joy of serving, thank you very much for your support and feedback. Know this isn’t goodbye — we’re looking forward to sharing what’s next.

(Thanks Tom James Watson.)

Create runnable jar from intellij

1. Configure a runnable JAR artifact

Open Project Structure:

File → Project Structure… (or Ctrl+Alt+Shift+S on Windows/Linux).

Go to Artifacts (left side).

Click the + button → JAR → From modules with dependencies….

In the dialog:

Module: select your module (e.g. SimpleJarDemo).

Main Class: click the ... button, choose your Main class.

Option Include in project build can stay checked if you want.

Click OK.

IntelliJ will create an artifact like:

Name: SimpleJarDemo:jar

Output directory: something like out/artifacts/SimpleJarDemo_jar.

By default it will use the “extract to the target JAR” layout, which is fine for a simple app (your compiled classes + any dependencies inside one JAR).

2. Build the JAR

Go to the main menu: Build → Build Artifacts….

In the popup, select your artifact (e.g. SimpleJarDemo:jar) → choose Build.

IntelliJ will compile and create the JAR in the artifact output directory, e.g.:<project-root>\out\artifacts\SimpleJarDemo_jar\SimpleJarDemo.jar

(You can see the exact path at the top of the Artifacts configuration page.)

3. Run the JAR from the command line

Open a terminal (Command Prompt, PowerShell, or shell):

bashCopy codecd <project-root>\out\artifacts\SimpleJarDemo_jar java -jar SimpleJarDemo.jar

android bound service 설명 youtube

original source : https://youtu.be/_xNkVNaC9AI

기본 전제)

service는 server 이며 이에 연결되는 activity는 client라고 이해하면 이해한다.

MainActivity

package com.codingwithmitch.boundserviceexample1; import android.arch.lifecycle.Observer; import android.arch.lifecycle.ViewModelProviders; import android.content.Context; import android.content.Intent;

   // UI Components    private ProgressBar mProgressBar;    private TextView mTextView;    private Button mButton;    // Vars    private MyService mService;    private MainActivityViewModel mViewModel;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mProgressBar = findViewById(R.id.progresss_bar);        mTextView = findViewById(R.id.text_view);        mButton = findViewById(R.id.toggle_updates);        mViewModel = ViewModelProviders.of(this).get(MainActivityViewModel.class);        setObservers();        mButton.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                toggleUpdates();            }        });    }    private void toggleUpdates(){        if(mService != null){            if(mService.getProgress() == mService.getMaxValue()){                mService.resetTask();                mButton.setText("Start");            }            else{                if(mService.getIsPaused()){                    mService.unPausePretendLongRunningTask();                    mViewModel.setIsProgressBarUpdating(true);

               }                else{                    Log.d(TAG, "onChanged: bound to service.");                    mService = myBinder.getService();                }            }        });        mViewModel.getIsProgressBarUpdating().observe(this, new Observer<Boolean>() {            @Override            public void onChanged(@Nullable final Boolean aBoolean) {                final Handler handler = new Handler();                final Runnable runnable = new Runnable() {                    @Override                    public void run() {                        if(mViewModel.getIsProgressBarUpdating.getValue()){                            if(mViewModel.getBinder().getValue() != null){ // meaning the service is bound                                if(mService.getProgress() == mService.getMaxValue()){                                    mViewModel.setIsProgressBarUpdating(false);                                }                                mProgressBar.setProgress(mService.getProgress());                                mProgressBar.setMax(mService.getMaxValue());                                String progress =                                        String.valueOf(100 * mService.getProgress() / mService.getMaxValue()) + "%";                                mTextView.setText(progress);                            }                            handler.postDelayed(this, 100);                        }                        else{                            handler.removeCallbacks(this);                        }                    }                };                // control what the button shows                if(aBoolean){                    mButton.setText("Pause");                    handler.postDelayed(runnable, 100);                }                else{                    if(mService.getProgress() == mService.getMaxValue()){                        mButton.setText("Restart");                    }                    else{                        mButton.setText("Start");                    }                }            }        });    }    @Override    protected void onResume() {        super.onResume();        startService();    }    @Override    protected void onStop() {        super.onStop();        if(mViewModel.getBinder() != null){            unbindService(mViewModel.getServiceConnection());        }    }    private void startService(){        Intent serviceIntent = new Intent(this, MyService.class);        startService(serviceIntent);        bindService();    }    private void bindService(){        Intent serviceBindIntent =  new Intent(this, MyService.class);        bindService(serviceBindIntent, mViewModel.getServiceConnection(), Context.BIND_AUTO_CREATE);    } }

위 코드에서 runnable 호출을 runnable 자체내에서 수행함으로써 looping를 한 부분이 생소했다.아래 그림 참조

또한 bindService()도 처음에는 이해하기 힘들었다. 두번째 파라미터 service connection을 전달부분이 어려웠다. 아래 MainActivityViewModel 코드를 확인하면 ServiceConnection obj 생성시에는 특별한 파라미터를 필요로 하지 않는다. ServiceConnection 는 activity에 service가 연결될때 호출되는 callback obj 로 추측한다. 

MainActivityViewModel

package com.codingwithmitch.boundserviceexample1; import android.arch.lifecycle.LiveData; import android.arch.lifecycle.MutableLiveData; import android.arch.lifecycle.ViewModel; import android.content.ComponentName; import android.content.ServiceConnection; import android.os.Handler; import android.os.IBinder; import android.util.Log; public class MainActivityViewModel extends ViewModel {    private static final String TAG = "MainActivityViewModel";    private MutableLiveData<Boolean> mIsProgressBarUpdating = new MutableLiveData<>();    private MutableLiveData<MyService.MyBinder> mBinder = new MutableLiveData<>();    // Keeping this in here because it doesn't require a context    private ServiceConnection serviceConnection = new ServiceConnection() {        @Override        public void onServiceConnected(ComponentName className, IBinder iBinder) {            Log.d(TAG, "ServiceConnection: connected to service.");            // We've bound to MyService, cast the IBinder and get MyBinder instance            MyService.MyBinder binder = (MyService.MyBinder) iBinder;            mBinder.postValue(binder);        }        @Override        public void onServiceDisconnected(ComponentName arg0) {            Log.d(TAG, "ServiceConnection: disconnected from service.");            mBinder.postValue(null);        }    };    public ServiceConnection getServiceConnection(){        return serviceConnection;    }    public LiveData<MyService.MyBinder> getBinder(){        return mBinder;    }    public LiveData<Boolean> getIsProgressBarUpdating(){        return mIsProgressBarUpdating;    }    public void setIsProgressBarUpdating(boolean isUpdating){        mIsProgressBarUpdating.postValue(isUpdating);    } }

MyService

package com.codingwithmitch.boundserviceexample1; import android.app.Service; import android.content.Intent; import android.os.Binder; import android.os.Handler; import android.os.HandlerThread; import android.os.IBinder; import android.support.annotation.Nullable; import android.util.Log; public class MyService extends Service {    private static final String TAG = "MyService";    private final IBinder mBinder = new MyBinder();    private Handler mHandler;    private int mProgress, mMaxValue;    private Boolean mIsPaused;    @Override    public void onCreate() {        super.onCreate();        mHandler = new Handler();        mProgress = 0;        mIsPaused = true;        mMaxValue = 5000;    }    @Nullable    @Override    public IBinder onBind(Intent intent) {        return mBinder;    }    public class MyBinder extends Binder{        MyService getService(){            return MyService.this;        }    }    public Boolean getIsPaused(){        return mIsPaused;    }    public int getProgress(){        return mProgress;    }    public int getMaxValue(){        return mMaxValue;    }    public void pausePretendLongRunningTask(){        mIsPaused = true;    }    public void unPausePretendLongRunningTask(){        mIsPaused = false;        startPretendLongRunningTask();    }    public void startPretendLongRunningTask(){        final Runnable runnable = new Runnable() {            @Override            public void run() {                if(mProgress >= mMaxValue || mIsPaused){                    Log.d(TAG, "run: removing callbacks");                    mHandler.removeCallbacks(this); // remove callbacks from runnable                    pausePretendLongRunningTask();                }                else{                    Log.d(TAG, "run: progress: " + mProgress);                    mProgress += 100; // increment the progress                    mHandler.postDelayed(this, 100); // continue incrementing                }            }        };        mHandler.postDelayed(runnable, 100);    }    public void resetTask(){        mProgress = 0;    }    @Override    public void onTaskRemoved(Intent rootIntent) {        super.onTaskRemoved(rootIntent);        Log.d(TAG, "onTaskRemoved: called.");        stopSelf();    }    @Override    public void onDestroy() {        super.onDestroy();        Log.d(TAG, "onDestroy: called.");    } }

Ways to Create a Thread in Java

Ways to Create a Thread in Java

As we know, whenever a Java program executes, a thread is created automatically which is coined as the main thread. The main thread is responsible for the creation and termination of other threads from beginning to the end of a program.

So, Java provides two approaches to create a thread.

1) By extending Thread Class 2) By Implementing Runnable Interface

Why two Approaches?

The reason for this is…

La Sportiva TX Guide Review: The Most Runnable Approach Shoe

[ad_1]

October 18, 2019 | By Cory Smith

The La Sportiva TX Guide is at home on both flat terrain and near-vertical crags. It’s a great choice for fast-and-light hikers on technical terrain.

As the horizontal world of running and the vertical world of climbing start to blend,there is a gap in technical footwear suitable for these hybrid adventures. You either lean toward a trail-running…
