NativeActivity sample fails

[Eric]

I did a ndk-build on the NativeActivity sample, then opened it in
eclipse and tried to run it.

It complained that the project was missing a "src" directory, so I
added an empty "src" directory.

That made the compiler happy and it deployed to my device, but then I
get this error message:

10-29 17:21:06.068: E/AndroidRuntime(12191):
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example.native_activity/android.app.NativeActivity}:
java.lang.IllegalArgumentException: Unable to find native library:
native-activity

I looked inside the .apk, and I see lib\armeabi\libnative-activity.so.

Any idea why it would be unable to find it?

I already tried purging my phone of any previous versions of my
project and redeploying, that doesn't fix it.

I guess I will use the san-angeles way till I can figure out what's
wrong.

using windows x64, eclipse indigo, latest android sdk and ndk

Latest eclipse plug-in, too?

[Eric]

Yes latest adt too.
Downloaded and installed the whole suite on Saturday.

So, I have opened several samples and they all work except for
NativeActivity.
I uninstalled and reinstalled everything

I do ndk-build of NativeActivity sample jni directory

ericstob@ericvaio /cygdrive/c/Android/android-ndk-r6b/samples/native-
activity/jni
$ ndk-build
Compile thumb : native-activity <= main.c
Compile thumb : android_native_app_glue <= android_native_app_glue.c
StaticLibrary : libandroid_native_app_glue.a
SharedLibrary : libnative-activity.so
Install : libnative-activity.so => libs/armeabi/libnative-
activity.so

ericstob@ericvaio /cygdrive/c/Android/android-ndk-r6b/samples/native-
activity/jni
$

I go to eclipse and click New -> Project -> From Existing Source, C:
\Android\android-ndk-r6b\samples\native-activity

I click run as android app and select my device, and I get this:

11-06 17:06:57.328: E/AndroidRuntime(18418):

java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example.native_activity/android.app.NativeActivity}:
java.lang.IllegalArgumentException: Unable to find native library:
native-activity

but when I open my .apk I see libnative-activity.so there:
ericstob@ericvaio /cygdrive/c/Android/android-ndk-r6b/samples/native-
activity/bin
$ unzip NativeActivity.apk -d temp
Archive: NativeActivity.apk
inflating: temp/AndroidManifest.xml
extracting: temp/resources.arsc
inflating: temp/classes.dex
inflating: temp/lib/armeabi/libnative-activity.so
inflating: temp/META-INF/MANIFEST.MF
inflating: temp/META-INF/CERT.SF
inflating: temp/META-INF/CERT.RSA

Would appreciate some help, I can't understand why it would not work
if the .so is there in the .apk

hello

Maybe, you have to check AndroidManifest.xml,

Min SDK version -> 9 or later
Target SDK version -> 9 or later

$ndk-build clean
$ndk-build

because NativeActivity is only support from Gingerbread.

ANSWER! :-)

set android:hasCode="true" in AndroidManifest.xml
