Hello,

I'm manually installing a library package that contain some bitmaps. I'm able to download and install the cod file but when I save the new module, the method isResetRequired() method return false.

Next I start the application but no images are shown. Images are obtained with Bitmap.getBitmapResource(module, name);

I tried to force the reset of the device with :

int timeDelay = 1000 * delay;
ApplicationManager myMgr = ApplicationManager.getApplicationManager();
ApplicationDescriptor myDsc = ApplicationDescriptor.currentApplicationDescriptor(); 

Date myDate = new Date();

myMgr.scheduleApplication(myDsc, myDate.getTime()+timeDelay, true);
Device.requestPowerOff(true);

But it doesn't seem to work on simulator. If I restart (Shift + ALT + DEL) the device (real one) the images appears without any problem.

I'm using OS 4.5 with a Curve 8330.

Has the library been loaded before the application?  If not, a reset may be required.  Note that the library itself may not require a reset (which is why you see false) but a reset could be required for your application to link to the library (if it was already installed).

Hi,

the application is installed on the device and after that, it look for required module. If those modules can't be found, the application will download and install it. Is there a way to link my application to the newly installed library to force a restart?

[MSohm]

There is no way for a third party application to programmatically kick off the linking process.  I think the closest you can get is to prompt the user to manually perform a hard reset to complete your install.

Ok I tought that would be the answer. For the hard reset, Is there a way to show the (Reset is require) popup? I saw some hints on the forum, but it talk about installing - running - uninstalling a dummy application. I'd love to avoid that kind of manipulation if possible.

There is no direct way to show that reset prompt, unless an action taken on an individual COD file actually does require a reset (such as the workaround you describe).
