I'm using purely native NDK in my project (Native Activity). It works fine when I add Prebuilt static libraries with my .so in Android.mk file. But when I try linking Prebuilt shared library, it shows the below exception:
03-27 16:42:09.982: E/AndroidRuntime(1275): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.irrlicht.example/android.app.NativeActivity}: java.lang.IllegalArgumentException: Unable to load native library: /data/app-lib/com.irrlicht.example-1/libHelloWorldMobile.so
Here is my Android.mk file:
....
include $(CLEAR_VARS)
LOCAL_C_INCLUDES := /Users/karthi/Android/openal-soft-master/jni/OpenAL/include
LOCAL_MODULE := openal
LOCAL_SRC_FILES := /Users/karthi/Android/openal-soft-master/libs/armeabi/libopenal.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := HelloWorldMobile
LOCAL_CFLAGS := -D_IRR_ANDROID_PLATFORM_ -pipe -fno-exceptions -fno-rtti -fstrict-aliasing
LOCAL_C_INCLUDES := -I ../../include -I /Users/karthi/Android/openal-soft-master/jni/OpenAL/include
LOCAL_SRC_FILES := main.cpp android_tools.cpp game.cpp
LOCAL_LDLIBS := -lEGL -llog -lGLESv1_CM -lGLESv2 -lz -landroid
LOCAL_SHARED_LIBRARIES := openal
include $(BUILD_SHARED_LIBRARY)
and in my AndroidManifest.xml:
<activity android:name="android.app.NativeActivity"
android:label="HelloWorldMobile"
android:launchMode="singleTask"
android:configChanges="orientation|keyboardHidden"
android:screenOrientation="landscape"
android:clearTaskOnLaunch="true">
<meta-data android:name="android.app.lib_name" android:value="HelloWorldMobile" />
<intent-filter>
<action android:name="android.intent.action.MAIN" />
finally in Application.mk:
APP_PLATFORM := android-18
APP_MODULES := HelloWorldMobile
APP_STL := stlport_static
I have also tried replacing the last line by,
APP_STL := stlport_shared
What else should I do to link a prebuilt shared library with my native library ? What am I missing here ? Any help will be appreciated.

03-28 11:57:52.779: W/ActivityManager(275): Force finishing activity com.irrlicht.example/android.app.NativeActivity
I have solved this issue by creating a subclass of Native Activity and loaded the shared library as below:
package com.irrlicht.example;
public class MyActivity extends android.app.NativeActivity {
static {
System.loadLibrary("HelloWorldMobile");
System.loadLibrary("openal");
}
}
and in AndroidManfest.xml, I'v included MyActivity instead of android.app.NativeActivity. Got this solution from here . But is there a way to completely solve this issue without using java class?
