退出Activity後,webview依然在播放音頻視頻

  @Override
    protected void onPause() {
        super.onPause();
        try {
            if (mWebView != null) {
                mWebView.getClass().getMethod("onPause").invoke(mWebView, (Object[]) null);
                isOnPause = true;
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        try {
            if (isOnPause) {
                if (mWebView != null) {
                    mWebView.getClass().getMethod("onResume").invoke(mWebView, (Object[]) null);
                }
                isOnPause = false;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mWebView != null) {
            mWebView.destroy();
            mWebView = null;
        }
        isOnPause = false;
    }
