Which apk(s) to be installed?

[jiapei100]

Hi, all:

I'm trying to play with the newest OpenCV-2.4.3.1-android-sdk . 

My Hosting environment: Ubuntu 12.04 + OpenCV 2.4.3 + OpenCV-2.4.3.1-Anrdoid + android-sdk_r21-linux + android-ndk-r8c-linux-x86

Since I met exactly the same problem mentioned at https://groups.google.com/forum/#!msg/android-opencv/XA57SdICg8w/aNKq2094QRMJ

I'll have to run the command line(s):

<Android SDK path>/platform-tools/adb install <OpenCV4Android SDK path>/apk/OpenCV_2.4.2_Manager.apk
<Android SDK path>/platform-tools/adb install <OpenCV4Android SDK path>/apk/OpenCV_2.4.2_binary_pack_armv7a.apk

However, I found a lot of apk files under <OpenCV4Android SDK path>

peijia@peijia-GA-870A-UD3:/opt/OpenCV-2.4.3.1-android-sdk/apk$ ls
OpenCV_2.4.3.1_binary_pack_armv7a.apk                OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk
OpenCV_2.4.3.1_Manager_2.3_armeabi.apk               OpenCV_2.4.3.1_Manager_2.3_mips.apk
OpenCV_2.4.3.1_Manager_2.3_armv7a-neon-android8.apk  OpenCV_2.4.3.1_Manager_2.3_x86.apk

which one(s) should I install?

I tried every apk, and the only error message I obtained is:

error: device not found

And, is there any documentation to clarify the differences among all of these apk file(s)??

Cheers

Pei

You need to install OpenCV Manager for your hardware platform. In most cases it is OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk. This package is targeted on arm-v7a devices with NEON module running Android 2.3 or higher. OpenCV_2.4.3.1_Manager_2.3_armeabi.apk is targeted on old arm-v5 and arm-v6 devices. OpenCV_2.4.3.1_Manager_2.3_armv7a-neon-android8.apk is targeted on devices with Arm-v7a+NEON SoCs and Android 2.2. Since 2.4.3 release OpenCV_2.4.3.1_binary_pack_armv7a.apk is optional and is targeted for Arm-v7a devices without NEON module, like Tegra2 SoC for example.

I've submitted the task #2642 to eliminate such confusions in future.

Thank you so much Alexander:

Seriously thank you...

If I don't connect my hardware platform, say, a Galaxy S1, and I only want to run the emulator on my Hosting Ubuntu 12.04, which apk should I install? And is it the reason that I always receive error: device not found without plugin a hardware (in my case, Galaxy S1) ?

Does that mean, I can't play with OpenCV Android on an emulator. The only way to successfully install an apk is to use a real hardware platform ???

Thank you in advance.

Best Regards

Hi, Sorry, problem solved.

I've got to run the emulator from AVD first, in order to have this virtual device !!

Thanks Alexander.

Well, unfortunately, problem continues.

As for the installation of OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk

peijia@peijia-GA-870A-UD3:/opt/android-sdk-linux/platform-tools$ adb install /opt/OpenCV-2.4.3.1-android-sdk/apk/OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk 
2287 KB/s (5848757 bytes in 2.497s)
        pkg: /data/local/tmp/OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]

As you can see, I've already have it installed after the emulator had successfully run. However, the current situation is:

1) By running the default app Camera, I got the message Insert a SD card before using the camera

2) By running the sample Sample2NativeCamera, problem continues:

"package not found" - "OpenCV Manager Package was not found! Try to install it?" , after I click "yes" , then show message "OpenCV Manager" - "package installation failed".

3) In addition, when I start Eclipse, I got the message 

Cannot run program "/ndk-build.cmd": Unknown reason

However, the following command line seems to tell my settings are correct.

peijia@peijia-GA-870A-UD3:~$ echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/android-sdk-linux/tools/:/opt/android-sdk-linux/platform-tools:/opt/android-ndk-r8c
peijia@peijia-GA-870A-UD3:~$ ls /opt/android-ndk-r8c/
build  documentation.html  ndk-build      ndk-gdb    ndk-which  prebuilt    RELEASE.TXT  sources  toolchains

peijia@peijia-GA-870A-UD3:~$ ls $NDKROOT
build  documentation.html  ndk-build      ndk-gdb    ndk-which  prebuilt    RELEASE.TXT  sources  toolchains
docs   GNUmakefile         ndk-build.cmd  ndk-stack  platforms  README.TXT  samples      tests

Can you please help to figure this out ?? 

Thank you very much.

Best Regards

Pei

Now, the 1st problem has been solved by specifying the webcam0 as the front camera in AVD Details settings.

And the 2nd problem can be solved by specifying a full path of ndk-build.cmd ; instead of using $NDKROOT/ndk-build.cmd

as mentioned in http://stackoverflow.com/questions/9620381/android-ndk-in-eclipse-cannot-run-program-ndk-build-unknown-reason

Now, the only problem left is:

Whenever I tried to run the sample code Sample2NativeCamera, I got:

"package not found" - "OpenCV Manager Package was not found! Try to install it?" , after I click "yes" , then show message "OpenCV Manager" - "package installation failed".

I'm 100% sure that I've already installed

OpenCV_2.4.3.1_binary_pack_armv7a.apk

OpenCV_2.4.3.1_Manager_2.3_armv7a-neon.apk

Any suggestions please?

cheers

Pei

Problem has been solved.
I should have installed some orther apk(s)...

Suggestions: if the users like me who don't know which apk(s) should be installed, just install all of the apks !!
