Vuforia sample fail with black screen in Native android

October 30, 2017 - 6:48am #3

Hi ,

I just start exploring the vuforia Android sdk and samples,  and i'm having some trouble with it .

This test was done on Samsung A5 Android 7.0 and Nexus 5X

SDK : vuforia-sdk-android-6-5-23.zip (12.29 MB)

Sample 1 : vuforia-samples-core-android-6-5-19.zip (33.09 MB)

Sample 2 : vuforia-samples-eyewear-android-6-5-19.zip (10.92 MB)

Sample 3 : vuforia-samples-advanced-android-6-5-19.zip (36.56 MB)

 

The only change i apply is i create app/libs   and i copy the Vuforia.jar library and i change the gradle dependency to :

dependencies {

    compile fileTree(dir:'libs', include: 'Vuforia.jar')

}

All the Sample test fail with a black screen or white screen just after i press "Start" in any of the sample option (Image targets , VuMark ...).

After that i figure out that there is a key licence and i follow the instruction mention here :https://library.vuforia.com/articles/Solution/How-To-add-a-License-Key-to-your-Vuforia-App

and i add my key licence here : Vuforia.setInitParameters(mActivity, mVuforiaFlags, "ASKRnBL/////AAAAGeRcP4vX.........");

The problem persist and i keep getting black screen and all button access is blocked .

This is the log showing on the console :

Hi,

 

Did you place the project under the correct folder? For example, for the ImageTargetsNative project, it should be under vuforia-sdk-android-6-5-19\samples\ImageTargetsNative-6-5-19

Hello. Add vuforia sdk accordingly this path: def VUFORIA_SDK_DIR = '../../../'.  (This path you can see in build.gradle file)
