"JNI错误(应用程序错误):弱的全局引用表溢出"为什么? [英] "JNI ERROR (app bug): weak global reference table overflow" why?

问题描述

由于此线程的本机代码泄漏，我不断收到此错误:

I keep getting this error due to a leak in my native code according to this thread:

ReferenceTable溢出(max = 512)JNI

但是，在我看来，AttachCurrentThread泄漏了.我尝试了这段代码，然后泄漏了

yet, it seems to me the the AttachCurrentThread leaks. I tried this code and it leaks

// this code LEAKS!
// C++:
void Engine::UpdateCamera(float x, float y, float z) {
    JNIEnv *jni;
    app_->activity->vm->AttachCurrentThread(&jni, NULL);
    //Do nothing
    app_->activity->vm->DetachCurrentThread();
    return;
}


// Java
public void updateCamera(final float x, final float y, final float z) {
    if (_label2 == null)
        return;

    StackTraceElement trace = new Exception().getStackTrace()[0];
    Log.e(APP_TAG, "Called:" +
            trace.getClassName() + "->" + trace.getMethodName() + ":" + trace.getLineNumber());

}

然后我只是注释掉所有内容，该程序停止泄漏并永远运行:(

Then I simply commented out everything and the program stopped leaking and ran forever :(

// this code never leaks, but it does not do anything either
void Engine::UpdateCamera(float x, float y, float z) {
    JNIEnv *jni;
    //app_->activity->vm->AttachCurrentThread(&jni, NULL);
    //app_->activity->vm->DetachCurrentThread();
    return;
}

有人遇到AttachCurrentThread泄漏问题吗?

Has anyone experienced leaking issues with AttachCurrentThread?

谢谢.

推荐答案

您是否已连接到调试器?如果是这样，请断开连接，您可能会发现弱引用表已返回合理的值.

Are you connected to the debugger? If so, disconnect and you may find the weak reference table returns to a reasonable value.

我有同样的问题；如果我与调试器一起运行，则会发生这种情况.

I had this same problem; if I run with the debugger, this occurs.
