Set Configuration in EmulatorWrapper.java

• Call initializeConfiguration

final ProfileEnvironment env = new ProfileEnvironment(); ProfileConfiguration profileconfiguration = (ProfileConfiguration)env.createConfiguration(); try { initializeConfiguration(profileconfiguration, file); ## Configuration based on input preferences file env.setCmdLineProperties(file);

private void initializeConfiguration(ProfileConfiguration profileconfiguration, File file) throws IOException { try { preferences = new PropertiesFile(new File(DEFAULT_PREFS_LOC)); ## create empty file if(file != null) { PropertiesFile propertiesfile = new PropertiesFile(file); ## create based on file (file: preference file given from prompt) preferences.setPropertiesList(propertiesfile.getPropertiesList()); ## copy } TracingOptions tracingoptions = new TracingOptions(); tracingoptions.setFromProperties(preferences); ## 넘겨줌 tracingoptions.setTraceConfiguration(profileconfiguration); String s = preferences.getProperty("heap.size"); if(s != null) profileconfiguration.setHeapSize(s); String s2 = preferences.getProperty("http.proxyHost");

Set Configuration in EmulatorWrapper.java

if(s2 != null && !s2.equals("")) { System.setProperty("http.proxyHost", s2); String s3 = preferences.getProperty("http.proxyPort"); if(s3 != null && !s3.equals("")) { System.setProperty("http.proxyPort", s3); ## set To System profileconfiguration.setHttpProxy(s2 + ":" + s3); ## set ProfileConfiguration } else { System.setProperty("http.proxyPort", null); profileconfiguration.setHttpProxy(s2); } } String s4 = preferences.getProperty("https.proxyHost"); if(s4 != null && !s4.equals("")) { String s5 = preferences.getProperty("https.proxyPort"); if(s5 != null && !s5.equals("")) profileconfiguration.setHttpsProxy(s4 + ":" + s5); else profileconfiguration.setHttpsProxy(s4); } }}

Calls to set

ProfileEnvironment.java• Run()

– New File(ToolkitDirs.LIB, “emulator.properties”) 파일 생성후 그 파일의 propertylist 와 configuration property 를 getPropertiesList() 와 getconfiguration Properties(c) 메소드를 통해 정보를 저장한다 .

– runEmulator() 호출

• runEmulator(Properties p, String as[])– 에뮬레이터를 실행시킬 새로운 EmulatorInvoker 를 생성하고

그 Invoker 를 통해 저장한 property 정보를 넘겨주면서 에뮬레이터를 실행

– getEmulatorClass();– New Emulatorinvoker();

• EmulatorWrapper.java 내에서 ProfileEnvironment.Start(profileconfiguration, as5) 호출

• ProfileEnvironment 소스내에서 start() 호출– Static void start(EmulatorConfiguration emulatorconfiguration,

String as[]) 호출 – Runner.start(emulatorconfiguration, as);

• getEmulatorThread(), – verifyVMVersion(): 자바 버전체크 – setproperty(lime.loader, KWAPPER_Path) – KVMTHread()

• isSynchronouMode() 호출
