[suspend] manta doesn't resume back if suspended with the camera app opened

[Ricardo Salveti]

Tested with build #94 (nexus 10).

Steps:
 * Open camera app
 * Hit power to suspend
 * Hit power to resume

Expected result:
 * The device will resume and working as before

Actual result:
 * Device hangs hard, need to reboot by pressing the power key >= 7 seconds (hard reboot)

I am not able to reproduce that. Maybe fixed since the flipped image?

[Günter Schwann (schwann)]

I can now see that behavior on galaxy nexus.

[Günter Schwann (schwann)]

Well - the device does not hang. But camera does not show the preview/viewfinder.

[Bill Filler (bfiller)]

Steps to reproduce on maguro:
- launch camera
- verify preview is shown
- go back to shell
- switch back to Camera

Expected results:
- camera preview still shown

Actual results:
- camera preview not shown

Works on the N10 btw.

Using image 20130726.1 on maguro, with the latest qtvideo-node and qtubuntu-camera works ok

[Günter Schwann (schwann)]

In image 20130726.1 the Qt.application.active property does not change, when the app is closed. In newer images it does. So as the property does not change, the camera-app does not disconnect on close, and then try to connect again when reopened.

[Günter Schwann (schwann)]

the problem is, that in android
frameworks/av/services/camera/libcameraservice/CameraClient.cpp the function
static int getCallingPid() {
    return IPCThreadState::self()->getCallingPid();
}
always returns 0. I guess that's because of the flipped container image,
getting the process ID is broken.

Because of that mClientPid is always 0, and that causes
CameraClient::disconnect() to abort in line 232

The reason that the N10 works, is that the N10 uses CameraClient2

works on mako
maguro is eol
