Android APK 추출 툴

Android 화면 크기 읽기, dpi, inch, cm

1. DPI 얻기

DisplayMetrics dm = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(dm);

int dpiClassification = dm.densityDpi;

float xDpi = dm.xdpi;

float yDpi = dm.ydpi;

도트 퍼 인치(Dots per inch, DPI)는 인쇄와 디스플레이 해상도의 측정 단위이며, 특히 1 제곱인치 (2.54 제곱센티미터) 공간 안에 만들어진 점이나 화소의 수를 말한다.

ex) DPI 가 30 이라는 말은 30 dots(pixel) 이 1 inch 라는 말이다.

1inch 를 화면에 그리고 싶으면

canvas.drawLine( x , y , x + xdpi , y );

1cm 를 화면에 그리고 싶으면

canvas.drawLine( x , y , x + xdpi / 2.54  , y );

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

LocationManager locationManager;

GoogleMap googleMap = ((SupportMapFragment) getSupportFragmentManager()

.findFragmentById(R.id.map)).getMap();

locationManager = (LocationManager) this

.getSystemService(Context.LOCATION_SERVICE);

Criteria criteria = new Criteria();

criteria.setAccuracy(Criteria.ACCURACY_COARSE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setSpeedRequired(false);

String provider = locationManager.getBestProvider(criteria, true);// "gps";

Location location = locationManager.getLastKnownLocation(provider);

double[] result = new double[] {

location.getLatitude(), location.getLongitude()

};

LatLng myPosition = new LatLng(result[0], result[1]);

googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(myPosition, 15));

Marker myMarker = googleMap

.addMarker(new MarkerOptions()

.position(new LatLng(result[0], result[1]))

.title("MyPosition")

.icon(BitmapDescriptorFactory

.fromResource(R.drawable.ic_launcher)));

Android Geocoding – Showing User Input Location on Google Map Android API V2

In this article, we will create an Android application which facilitates users to input street address in an EditText and on clicking the find button, application draws corresponding location marker on the Google Map Android API v2 using Google’s Geocoder API.

This application is an upgraded version of the application discussed in the article titled “Android Geocoding – Showing User Input Location on Google Map” where the location is shown in Google Map Android API v1.

This application is developed in Eclipse 4.2.1 with ADT plugin ( 21.0.0 ) and Android SDK ( 21.0.0 ) and is tested in a real Android Phone with Android 2.3.6  ( GingerBread ).

1. Download and configure Google Play Services Library in Eclipse

Please follow the given below link to setup Google Play Service library in Eclipse.

http://developer.android.com/google/play-services/setup.html

2. Create a new Android Application Project namely “LocationGeocodingV2″

Figure 1 : Create new Android application project

3. Configure Android Application Project

Figure 2 : Configure Android Application Project

4. Design Application Launcher Icon

Figure 3 : Design Application Launcher Icon

5. Create a blank activity

Figure 4 : Create a blank activity

6. Enter Main Activity Details

Figure 5 : Enter Main Activity Details

7. Link to Google Play Service Library

Figure 6 : Link to Google Play Services Library

8. Get the API key for Google Maps Android API v2

We need to get an API key from Google to use Google Maps in Android application. Please follow the given below link to get the API key for Google Maps Android API v2.

https://developers.google.com/maps/documentation/android/start

9. Add Android Support library to this project

By default, Android support library (android-support-v4.jar ) is added to this project by Eclipse IDE to the directory libs. If it is not added, we can do it manually by doing the following steps :

• Open Project Explorer by Clicking “Window -> Show View -> Project Explorer”
• Right click this project
• Then from popup window, Click “Android Tools -> Add Support Library “

10. Update the file AndroidManfiest.xml

11. Update the layout file res/layout/activity_main.xml

12. Update the file res/values/strings.xml

13. Update the file src/in/wptrafficanalyzer/locationgeocodingv2/MainActivity.java

14. Screenshot of the application in execution

Windows 7 환경에서 Android Fulll Source 다운로드 받기

http://source.android.com/source/downloading.html

위 링크에서

안드로이드 전체 소스코드를 다운로드 받을 수 있다.

Windows 환경에서 받는 방법을 설명한다

Cygwin: http://www.cygwin.com

Cygwin 설치 시 추가로 선택해야 할 패키지들: curl, git, python, readline

일단 Cygwin 을 이용하여 Windows 환경에서 리눅스 명령어를 사용 할 수 있게한다.

그 중 위 4개의 명령어는 반드시 필요하다.

Cygwin 홈페이지에서 setup.exe 파일을 다운로드한 후 실행한다.

대부분의 설정은 default 상태로 유지하고 넘어가는데, mirror site 선택할 때는 한국 내에 거주하는 경우 ftp.daum.net 을 선택해주는 것이 가장 빠르게 받을 수 있는 방법이다.

설치해야 할 package를 선택하는 화면이 나오면 우측 상단의 "View" 버튼을 눌러 Full 보기 상태로 만든 후 위에서 언급했던 모듈들을 추가로 선택해준다.

View 버튼은 그림에서 1. 번 위치에 있다.

모듈 설치 선택하는 방법은 그림에서 2. 번 위치를 눌러주는 것으로 결정이 가능하다.

Keep: 이미 설치되어 있는 버전을 그대로 유지할 것임을 나타냄.

Skip: 아직 설치되지 않은 모듈이며 설치하지 않을 것임을 나타냄. 이 부분을 마우스로 클릭하면 버전 번호로 바뀌게 되는데 설치 과정에서 설치하게 될 것임을 나타냄.

Uninstall: 이미 설치되어 있는 모듈을 제거할 것임을 나타냄.

Cygwin 설치가 완료되면

http://source.android.com/source/downloading.html

경로에 있는 대로

Full Source 를 받을 폴더로 Cygwin 에서 경로를 이동하고

curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > repo

repo 를 만든다.

chmod a+x ~/bin/repo

그 다음 repo 의 권한 설정을 변경해주고

repo init -u https://android.googlesource.com/platform/manifest

(위 명령어가 안 먹는 경우 git 설치가 덜 된 경우)

(http://git-scm.com/book/ko/%EC%8B%9C%EC%9E%91%ED%95%98%EA%B8%B0-Git-%EC%84%A4%EC%B9%98)

(위 링크로 들어가서 git 설치 후 진행)

repo 를 초기화 한 후

repo sync

repo sync 를 호출하게 되면 약 1시간 이상동안 android full source 를 다운로드 받게 된다.

중간에 이름과 이메일을 물어보는 질문이 있다.
