我正在为钛创建一个deezer模块。
可视化登录消息时出现问题。
这是我的DeezerAndroidModule.java（或其中很大一部分）
@Kroll.module(name="DeezerAndroidModule", id="deezer.android")
public class DeezerAndroidModuleModule extends KrollModule
{
private static final String TAG = "DeezerAndroidModuleModule";
private final String APP_ID = "xxx";
private final static String[] PERMISSIONS = new String[]{"basic_access","offline_access","email"};
private DeezerInterface deezerInterface;
private DeezerConnect connection;
{...}
@Kroll.method
public void loginDeezer()
{
connection.authorize(deezerInterface, PERMISSIONS, new ReconnectDialogHandler());
}
@Kroll.method @Kroll.getProperty
public String userId()
{
DeezerRequest request = new DeezerRequest( "/user/me" );
String result = null;
try {
result = connection.requestSync( request );
}//try
catch( MalformedURLException ex ) {
}//catch
catch( IOException ex ) {
}//catch
catch (OAuthException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (DeezerError e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
{...}
class ReconnectDialogHandler implements DialogListener {
@Override
public void onComplete(final Bundle values) {
SessionStore sessionStore = new SessionStore();
sessionStore.save( connection, deezerInterface );
}//met
@Override
public void onDeezerError(final DeezerError deezerError) {
}//met
@Override
public void onError(final DialogError dialogError) {
}//met
@Override
public void onCancel() {
}//met
@Override
public void onOAuthException(OAuthException oAuthException) {
}//met
}
问题是，当我调用
loginDeezer()函数时，应用程序将抛出通用的Java Exception而不提示登录视图...这是一个logcat标题

我的代码有什么不正确的地方？
最佳答案
借助XGouchet，我仅使用Activity就解决了这个问题：
在DeezerModule中
@Kroll.method
public void loginDeezer()
{
TiApplication appContext = TiApplication.getInstance();
Activity act = appContext.getCurrentActivity();
Intent myIntent = new Intent(act, DeezerInterface.class);
act.startActivity(myIntent);
}
并且DeezerInterface活动类为this
