You are advised to use MapFragment (extends the native Fragment component of Android and can be used to add a map to an app in the simplest way), or SupportMapFragment, instead of using your Fragment to embed Huawei MapView.
Update:
Please check the following codes:
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
if (LeakCanary.isInAnalyzerProcess(this)) {//1
// This process is dedicated to LeakCanary for heap analysis.
// You should not init your app in this process.
return;
}
LeakCanary.install(this);
}
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
}
}
