我正在开发一个应用程序，我将在浏览器中启动一个 url，我将从中启动我的应用程序。
假设如果我单击google.com，然后按回车，它将启动我的应用程序。为此，我尝试使用HttpFilterRegistryAPI。
作为参考，我正在使用HTTPFilterDemo应用程序。但目前在启动应用程序时，我得到了NullPointerException.
我在openFilter方法中编写了以下代码：
public Connection openFilter(String name, int mode, boolean timeouts) throws IOException {
Logger.out("Protocol", "it is inside the openFilter method");
_url = name.substring(2);
_requestHeaders = new HttpHeaders();
_responseHeaders = new HttpHeaders();
_responseHeaders.setProperty(HttpProtocolConstants.HEADER_CONTENT_TYPE, "text/html");
Logger.out("Protocol", "here it is come ::::44444444");
final int modHandle = CodeModuleManager.getModuleHandle("AppLaunchBrowser");
Logger.out("Protocol", "here is the module handle:::" + modHandle);
final ApplicationDescriptor[] apDes = CodeModuleManager.getApplicationDescriptors(modHandle);
final ApplicationDescriptor appDescriptor = new ApplicationDescriptor(apDes[0], new String[] {});
Logger.out("Protocol", "here is the app descriptor:::" + appDescriptor);
try {
final int appCode = ApplicationManager.getApplicationManager().runApplication(appDescriptor, true);
Logger.out("Protocol", "here is the app code:::" + appCode);
} catch (ApplicationManagerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// }
return this;
}
在应用程序类中，我正在创建替代入口点并使用如下：
public class AppLaunch extends UiApplication{
public static void main(String args[])
{
Logger.out("AppLaunch", args+"length of the arguments::::" +args.length);
if((args != null) && (args.length > 0) && (args[0].equals("background")))
{
Logger.out("AppLaunch", "in the alternate entry point");
// Logger.out("AppLaunch", args+"length of the arguments::::" +args.length);
HttpFilterRegistry.registerFilter("www.google.co.in", "com.innominds.ca", false);
}
else
{
Logger.out("AppLaunch", "Inside the Applaunch");
AppLaunch theApp = new AppLaunch();
theApp.requestForeground();
Logger.out("AppLaunch", "created the app launch object");
theApp.enterEventDispatcher();
// Logger.out("AppLaunch", "in the alternate entry point");
// HttpFilterRegistry.registerFilter("www.google.co.in", "com.innominds.ca", false);
}
}
public AppLaunch()
{
checkPermissions();
showTestScreen();
}
private void checkPermissions()
{
ApplicationPermissionsManager apm = ApplicationPermissionsManager.getInstance();
ApplicationPermissions original = apm.getApplicationPermissions();
if(original.getPermission(ApplicationPermissions.PERMISSION_BROWSER_FILTER) == ApplicationPermissions.VALUE_ALLOW)
{
// All of the necessary permissions are currently available
return;
}
ApplicationPermissions permRequest = new ApplicationPermissions();
permRequest.addPermission(ApplicationPermissions.PERMISSION_BROWSER_FILTER);
boolean acceptance = ApplicationPermissionsManager.getInstance().invokePermissionsRequest(permRequest);
if(acceptance)
{
// User has accepted all of the permissions
return;
}
else
{
}
}
private void showTestScreen()
{
UiApplication.getUiApplication().pushScreen(new AppLaunchScreen());
}
}
