집착남의 이야기

실행하는 기기의 버전에 맞춰 minSdkVersion을 맞춰준다.

1. execute 할때 error

Cannot execute task: the task has already been executed (a task can be executed only once)

라는 에러 생길 경우 한번 실행된것은 다시 execute 될 수 없기 때문에

task를 execute 할때마다 매번 new instance 한 후 execute한다.

2. return값 사용할 경우

1) public class MyAsyncTask extends AsyncTask<String, Void, Boolean> 처럼 마지막 파라미터에 return type 설정 후 doInBackground() 안에서 return 값 설정

2) execute.get() 해서 가져옴(대신 해당 thread에서 결과값 받아 온 후 main thread 실행 됨)

3. execute 시 파라미터 전달 하는 방법

예)

1) doInBackground(String... params){

String param1 = params[0];

String param2 = params[1];

2) 호출할 때는 execute("1", "2");

View를 상속하고 있는 객체면 모두 가능하다.

예를들어서 버튼으로 보면

Button button= (Button) findViewById(R.id.button);

button.setVisibility(View.GONE);         //화면에서도 사라지고 버튼 동작도 안된다.

button.setVisibility(View.INVISIBLE);   //화면에서는 사라지지만 투명하게 보이는 느낌을 준다.

button.setVisibility(View.VISIBLE);      //평상시하고 똑같은 모습이 보여진다.

1. http://hc.apache.org/downloads.cgi에서 HttpClient 다운

2. 압축 풀어서 httpclient-4.2.2.jar, httpcore-4.2.2.jar, httpmime-4.2.2.jar만 libs 폴더로 이동

3. 빌드

4. 하면 에러 발생(코드에 따라 다름)

※해결방법

build.gradle(module) 안에 android {

...

}

... 부분에

    packagingOptions {
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/LGPL2.1'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/notice.txt'
    }

추가 해야한다.

찾아보니 코드에 따라 추가해야 될게 다른거 같은데

원랜 DEPENDENCIES, NOTICE, LICENSE만 추가했다가 이것저것 추가하다보니 해결됨..

예전에 이클립스로 라이브러리 추가 할 때는 라이브러리 폴더에 jar 파일 추가해서 했었던거 같은데..

Android studio로 넘어오면서 굳이 그럴필요 없이

관련 lib들을 build.gradle에 dependencies 걸어주는 형태로 바뀌면서 좀 더 간단해 진거 같다.

물론 예전처럼 폴더를 만들고 해당 폴더에 jar파일을 넣어서 할 수도 있지만..

lib추가 하는법

1. jar 파일 있을 때

1) 해당 경로의 jar파일들을 모두 추가 할 때

① project > app > libs에 jar 파일 넣기

② build.gradle(module)에 가서 dependencies 부분에 compile fileTree(dir:'libs', include: ['*.jar']) 추가

2) jar 파일 1개씩 추가 할 때

① 해당 프로젝트 우클릭 - Open Module Settings - Dependencies -  추가 - File Dependency - jar파일 각각 추가

2. jar 파일 없을 때

1) build.gradle(module)에 가서 dependencies 부분에 compile 'com.android.support:appcompat-v7:22.2.0' 추가

2) 해당 프로젝트 우클릭 - Open Module Settings - Dependencies - 추가 - Library Dependency -com.android.support:appcompat-v7:22.2.0 추가

android sudtio에서 build.gradle에 있는 dependencies에 추가된 lib들을 찾아서 컴파일해주는 것 같은데 정확한 원리를 모르겠다..ㅋ

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 에서

1. A Windows installer for everything except PuTTYtel 다운

2. Putty 설치 경로 가서 puttyge.exe 실행

3. Generate 

4. Save private key

5. Putty 실행 후 Connection - SSH - Auth - Private Key file for authentication에 4번에서 생성한 키 입력

6. Session에 접속 정보 입력

필요한 권한을 AndroidManifest.xml에 추가해서 사용

커맨드창에서 C:\Program Files\Java\jdk1.8.0_45\bin까지 이동 후

keytool -list -v -keystore c:\users\사용자명\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

입력.

예를들어

C:\Program Files\Java\jdk1.8.0_45\bin>keytool -list -v -keystore c:\users\JBY\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

그러면 SHA1 : 부분에 키값이 나오고 이걸 복사해서 등록
