Bug 1465

Summary: Leak in Android_JNI_SetActivityTitle (SDL_SetWindowTitle)
Product: SDL Reporter: Martin Gerhardy <martin.gerhardy>
Component: *don't know*Assignee: Gabriel Jacobo <gabomdq>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>

Description Martin Gerhardy 2012-04-08 04:44:23 UTC 
Calling SDL_SetWindowTitle in a loop will result in a jvm crash because the jstring for the title is not marked as garbage collactable.


this fixed the issue:

extern "C" void Android_JNI_SetActivityTitle(const char *title)
{
    jmethodID mid;

    mid = mEnv->GetStaticMethodID(mActivityClass,"setActivityTitle","(Ljava/lang/String;)V");
    if (mid) {
    	jstring jtitle = reinterpret_cast<jstring>(mEnv->NewStringUTF(title));
        mEnv->CallStaticVoidMethod(mActivityClass, mid, jtitle);
        mEnv->DeleteLocalRef(jtitle);
    }
}

how to reproduce:
just do a loop with n = 513 and call SDL_SetWindowTitle with different title strings.
