I start ImageTargets activity from another activity, with some devices (not all), eg galaxy note or galaxy SIII, when i close and relaunch ImageTargets activity two or three times, it have OutOfMemoryCrash on loadTexture,is there some way to dealloc memory when close ImageTargets activity?

thanks

well, i have a tricky solution for that case.

i never use the backkey to exit my application, try to use an imagebutton or something in screen to exit your application. it works well for me, never crash when i relaunch the application

Hi, the textures are deleted (in native code) in this function:

JNIEXPORT void JNICALL
Java_com_qualcomm_QCARSamples_ImageTargets_ImageTargets_deinitApplicationNative(
                                                        JNIEnv* env, jobject obj)
{
    LOG("Java_com_qualcomm_QCARSamples_ImageTargets_ImageTargets_deinitApplicationNative");

    // Release texture resources
    if (textures != 0)
    {    
        for (int i = 0; i < textureCount; ++i)
        {
            delete textures[i];
            textures[i] = NULL;
        }
    
        delete[]textures;
        textures = NULL;
        
        textureCount = 0;
    }
}

This is triggered by the onDestroy() method in the main activity.

Can you check that that function is called when you exit your AR activity ?

is there any limit to the number of texture that i can load?

Those textures would not be a problem on a PC, but on a mobile device they can be quite large. This also depends on the specific device you are using, but I would suggets to reduce each image to half of its size, i.e.:

512x512 

Also, the 1536x1536 are not power-of-two, you should reduce them to 1024x1024 or 512x512 as well.

sorry, i replied you too long..

these is my 7 texture that i said:

1. TextSSumatera, 1024x1024px, 45Kb
2. TextSKalimantan, 1024x1024px, 34Kb
3. TextSSulawesi, 1024x1024px, 38Kb
4. TextSPapua, 1024x1024px, 30Kb
5. TextSJawa, 1024x1024px, 26Kb
6. TextGunungSumatera, 1536x1536px, 83Kb
7. TextGunungJawa, 1536x1536px, 124Kb

is my picture resolution or the size is too big?

Hi, what is the size of these textures ?
