[android-developers] Re: startActivity Problem
Thanks Yusuf,
that worked.
Still curious though, when did the startActivity behavior change? It
worked in an older project that was also 1.5.

Hi all,
I'm trying to call a service directly, and I'm getting an
ActivityNotFoundException thrown.
My main class looks like this:
---
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PackageManager pm = getPackageManager();
try {
Log.i(TAG,retrieving services:);
PackageInfo pinfo = pm.getPackageInfo(test.another,
PackageManager.GET_ACTIVITIES | PackageManager.GET_SERVICES);
for (ServiceInfo serv : pinfo.services) {
Log.i(TAG,declared service: +serv.name);
Log.i(TAG, package name: +serv.packageName);
Log.i(TAG, enabled: +serv.enabled);
Log.i(TAG, exported: +serv.exported);
}
} catch (NameNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Intent i = new Intent();
i.setClassName(test.another, test.another.MyService);
startActivity(i);
setContentView(R.layout.main);
}
---
--
My service is empty, minus some log messages:
---
-
public void onCreate() {
Log.i(T,created);
}
public void onStart(Intent i, int code) {
Log.i(T,started);
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
---
-
And the service is declared in the manifest file:
---
?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=test.another
android:versionCode=1
android:versionName=1.0
application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.Main
android:label=@string/app_name
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity
service android:name=MyService/service
/application
uses-sdk android:minSdkVersion=3 /
/manifest

When I run it in either the emulator or on my phone, I get this log:

[android-developers] Re: did someone implement a ScrollView with horizontal scroll support?
Here is one Google made earlier, except they forgot to flip x/y. Took
about an hour to convert. :)
Oh, and it might not work with the 1.1 SDK, because of the attribute
set changes. It works fine with the 1.0 SDK.

The code in setScrollXY is not called anywhere in the class, and was old test code to get around the fact that some fields/methods are not available in sub-classes in different packages. It can be and should have been removed, but then again, who has time for that? Michael On Mar 12, 1:44 pm, Romain Guy romain...@google.com wrote: Do NOT use this implementation. The setScrollXY() method changes field by reflection. Not only is it likely to break it's also VERY VERY inefficient. Especially given the lookup is done *every* single time. View already has methods to change the scroll X/Y values. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
