在Android8.0上使用LeakCanary检测到内存泄漏

使用Customized View自定义界面，进入扫码Activity, 退出就会出现内存泄漏，如下：

┬─── │ GC Root: Java local variable │ ├─ java.util.TimerThread thread │ Leaking: UNKNOWN │ Retaining 97.3 kB in 1340 objects │ Thread name: 'Timer-1' │ ↓ TimerThread.<Java Local> │ ~~~~~~~~~~~~ ├─ com.huawei.hms.scankit.p.Ua instance │ Leaking: UNKNOWN │ Retaining 97.0 kB in 1331 objects │ ↓ Ua.a │ ~ ├─ com.huawei.hms.scankit.p.Ta$b instance │ Leaking: UNKNOWN │ Retaining 97.0 kB in 1330 objects │ ↓ Ta$b.f │ ~ ├─ com.huawei.hms.scankit.p.Ta instance │ Leaking: UNKNOWN │ Retaining 96.6 kB in 1320 objects │ e instance of io.taucoin.torrent.publishing.ui.qrcode.ScanQRCodeActivity │ with mDestroyed = true │ ↓ Za.e │ ~ ╰→ io.taucoin.torrent.publishing.ui.qrcode.ScanQRCodeActivity instance ​ Leaking: YES (ObjectWatcher was watching this because io.taucoin.torrent. ​ publishing.ui.qrcode.ScanQRCodeActivity received Activity#onDestroy() ​ callback and Activity#mDestroyed is true) ​ Retaining 95.8 kB in 1296 objects ​ key = 1c2eea66-bb30-483a-8ba8-0a3d4576165a ​ watchDurationMillis = 70604 ​ retainedDurationMillis = 65594 ​ mApplication instance of io.taucoin.torrent.publishing.MainApplication ​ mBase instance of android.app.ContextImpl
