I have a workaround:

    static void fixLeakCanary696(Context context) {
        if (!isEmui()) {
            Log.w(TAG, "not emui");
            return;
        }
        try {
            Class clazz = Class.forName("android.gestureboost.GestureBoostManager");
            Log.w(TAG, "clazz " + clazz);

            Field _sGestureBoostManager = clazz.getDeclaredField("sGestureBoostManager");
            _sGestureBoostManager.setAccessible(true);
            Field _mContext = clazz.getDeclaredField("mContext");
            _mContext.setAccessible(true);

            Object sGestureBoostManager = _sGestureBoostManager.get(null);
            if (sGestureBoostManager != null) {
                _mContext.set(sGestureBoostManager, context);
            }
        } catch (Exception ignored) {
            ignored.printStackTrace();
        }
    }

Call fixLeakCanary696(getApplicationContext()) in Activity.onDestroy.

Seems a bug of huawei(EmotionUI) OS. I can not find the source code of class GestureBoostManager.

GC ROOT static android.gestureboost.GestureBoostManager.sGestureBoostManager
* references android.gestureboost.GestureBoostManager.mContext
* references org.chromium.android_webview.ResourcesContextWrapperFactory$WebViewContextWrapper.mBase

gaoyan10 on 10 Feb 2017

Maybe you can

sGestureBoostManager. mContext =  AggregationEntryActivity.this.getApplicationContext() // reference a global context?

Guang1234567 on 22 Feb 2017

@zhangXiaolizi @gaoyan10 Did you find the answer？

ruijun on 28 Feb 2017

@ruijun 没有，我在华为的论坛里面反馈过这个问题，也一直没得到回复呢。

zhangXiaolizi on 28 Feb 2017

@zhangXiaolizi 我也出现过这个问题，但找不到是哪里用到引起的，你有头绪吗？

ruijun on 28 Feb 2017

@ruijun @zhangXiaolizi 在AggregationEntryActivity中有用自定义的webview吗？

marekchen on 3 Mar 2017

@marekchen 我的是没有，你有遇到过类似的问题？

ruijun on 4 Mar 2017

@ruijun

GC ROOT static android.gestureboost.GestureBoostManager.sGestureBoostManager
* references android.gestureboost.GestureBoostManager.mContext
* references org.chromium.android_webview.ResourcesContextWrapperFactory$WebViewContextWrapper.mBase

从leak信息看，应该是和webview 是有关的，我的页面中有webview。

marekchen on 6 Mar 2017

@ruijun 应该是华为系统的一个漏洞。我的没有WebView的页面也会出现这种情况，我的之前是6.0的时候没有这个泄漏，在更新到EMUI5.0 android 7.0的时候出现的这个泄漏

zhangXiaolizi on 6 Mar 2017

我今天也遇到这个问题了

何止是 webview,输入法也有问题，坑死人了。

总之有几个华为的泄漏，

同款手机同款漏洞

marekchen on 29 Mar 2017

华为p9，Android7.0，也经常遇到这个问题。查了很久也没查到，7.1.1的sdk里都没有这个类，应该是华为自己加的类，EMUI5.0的bug。

@Piasy 能问下你这段代码
为什么给静态成员【sGestureBoostManager.mContext】赋值ApplicationContext就不会泄露了？
