[android-developers] problem of compiling Opencore to enable BUILD_STREAMING_MANAGER_NODE=y

[tu]

Hi everybody, I am re-compiling opencore from the software stack of
Eclair, my modification likes the following:
1) eclair/external/opencore/build_config/opencore_dynamic/
pv_config_selected.mk, set  BUILD_STREAMING_MANAGER_NODE=y
2)eclair/external/opencore/build_config/opencore_dynamic/pv_config.h
#define BUILD_STREAMING_MANAGER_NODE 1

then I re-compile all of Eclair, I met the following error message:

[android-developers] Re: PackageManager.installPackage() ?

[tu]

I do think so! I think there is no way to register a manifest other than
package manager API now. The nearest approach I got is the following:
 ActivityThread thread = ActivityThread.currentActivityThread();
 PackageManager manager = this.getPackageManager();
 PackageInfo info =
manager.getPackageArchiveInfo("/data/data/my.test/install/testHello.apk",
0x);
 ApplicationInfo ai = info.applicationInfo;
 ai.dataDir = "/data/data/my.test";
 ai.processName = "my.test";
 ai.uid = 10008;  //uid of the running package
 ActivityThread.PackageInfo actPackageInfo = thread.getPackageInfo(ai,
Context.CONTEXT_IGNORE_SECURITY|Context.CONTEXT_INCLUDE_CODE
);
 thread.getApplicationThread().scheduleLaunchActivity(intent, null,
ai.packageName, "/data/data/my.test/",
   "/data/data/my.test/", ai.theme, ai.nonLocalizedLabel, ai.labelRes,
null, null, null, false);

It would work if ApplicationThread class is public.

[android-developers] Re: PackageManager.installPackage() ?

[tu]

As far as I know, launching an activity in an uninstalled apk is impossible.
The problem is not the correct context enviroment, but the manifest file not
be registered. That means you can use resouces and codes in dynamic loaded
apk, but can not use activities, services directly.

[android-developers] GTalk Data Send parse error!

[tu]

I found when I put string like "name <[EMAIL PROTECTED]>" in the intent sent by 
gtalk
data send service. I got an "invalid-xml" error tagged by "Smack/Packet".  I
think it just because there is '<' and '>' in the string. So I think it
maybe a bug for gtalk data send service

http://rcpandroid.googlecode.com/files/RCPAndroid.apk

2. Unify-Message Open Platform

RCP for Android introduce some OSGI's bundle features to android. Maximally
supports various building blocks of Android and the operation of multi
processes. Take advantages of both OSGi and Android.

Unify-Message Open Platform is a message center for Andorid, based in RCP
for android.

[android-developers] Re: Announcing: RCP for Android & Unify-Message Open Platform

[tu]

I found that there is much more download for RCPAndroid.pdf than
RCPAndroid.apk. But I packed many source code and client libary into apk's
assets directory. So I recommend download the apk too.

I hope RCP for Android is useful to developers wether they submitted to ADC
or not.

Yeah, the framework is mostly transparent. You can generate your own private
key and encrypt or sign your bundle. The main-apk has public key. You can
try to download my project and extract sources packed in apk to study how to
bundle programming. I will upload my security solutions some days later.

Then performance is acceptable according to my test. It cost a few seconds
to install a bundle. Because the ClassLoader provided by Android now is only
support apk file than memory bytes, so I have to decrypt the bundle(sub-apk)
to main-apk's data directory.

read "doc/StartGuide.pdf" first, then go through demos directory. RCPAndroid
is the Main-apk project. "RCPAndroid.apk" is the compiled apk.
There are some batch files in tool directory for generating keypairs,
ciphering and packing bundle.
