Native Camera does not work on Android 4.3 (Nexus 7 2013) (Bug #3327)

Thank you for your report. It looks like camera is blocked by some other process. Try to open standard camera app. Does it work correctly? Do you try 2.4 branch and OpenCV Manager? Try to install OpenCV example tutorial-1 camera preview and OpenCV Manager. Does it work?

Thanks for your reply, actually I did not use opencv Manager. I removed all java code (those stuff in src/) from the sample "native-activity", then I adapted the AndroidManifest.xml like this:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
      package="org.opencv.samples.NativeActivity" 
      android:versionCode="1" 
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="9" />
    <application android:label="@string/app_name" 
                 android:icon="@drawable/icon" 
                 android:debuggable="true">

        <activity android:name="android.app.NativeActivity" 
                  android:label="@string/app_name" 
                  android:screenOrientation="landscape" 
                  android:configChanges="keyboardHidden|orientation">
            <meta-data android:name="android.app.lib_name" 
                    android:value="native_activity" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                  </intent-filter>
        </activity>
    </application>

   <uses-permission android:name="android.permission.CAMERA"/>

   <uses-feature android:name="android.hardware.camera" android:required="false"/>
   <uses-feature android:name="android.hardware.camera.autofocus" android:required="false"/>
   <uses-feature android:name="android.hardware.camera.front" android:required="false"/>
   <uses-feature android:name="android.hardware.camera.front.autofocus" android:required="false"/>

</manifest>

After run

> ndk-build

> ant debug install

Because I use the sample in an unusual way, maybe it should not be considered as a bug.
I do not know much about the underlying mechanism for Android camera, any help would be appreciated.

ps.
1. For a developing version, how to compile opencv-manager?
2. What is relation between prebuilt libnative_camera_r4.3.0.so and module/androidcamera?

Your Manifest looks ok. I'm not able to analyze problem right now, but I return to it in the nearest future. Just one additional question, does new Nexux 7 have back camera?

1. You do not need to compile OpenCV Manager. It is a way of distribution for OpenCV. If you want to link with OpenCV from master branch you can do it statically or dinamicaly in run time by initDebug() method. See Android tutorial on docs.opencv.org for more details.

2. modules/androidcamera contains code for all libnative_camera_xxx.so libraries and thin wrapper for it to use it from OpenCV. Android camera libraries are built without exceptions and RTTY, so we have to use separate libraries-wrappers to fit interface differences on different Android versions and solve RTTY linking issues.

Ok, thank you, Nexus 7 (2013) has two cameras, and I tested this sample using both front and back camera, and got same result.
I paste the log produced by Android's native camera app. I hope it is helpful for you.
