1. The network is abnormal
No offline operation
No network, wifi, mobile network three kinds of network switching
In a weak network scenario, the server does not respond in time
If the program is not properly protected, the app will flash back
2, the app program is not compatible with the data returned by the interface
The data returned by the interface varies widely, including null," & # 34; , & # 34; & # 34; If the app side is not well processed, it will cause a flash back
3, memory leakage, the program did not release memory in time
For example, in the security monitoring software, there are live broadcast and replay functions, frequent switching pages, there is no good release of resources, will cause flash back
4. The version is too low
The APP version is too early, and the SDK of the app is incompatible with the mobile phone's system, causing a flash back
Some apis are present in older versions but not in newer versions, causing objects to be empty and causing flashbacks
5. Permission issues
Usually, the AndroidManifest file forgets to configure the relevant permissions
6, the design is not reasonable
1 interface, the amount of data pulled is too large, the request result will be slow, and occupy a lot of memory, the APP will blink
7. Switch between different apps
Interactive test, may have a flash back
8. Component problems
Where the APP accesses the network, the ImageView in the component is not properly downloaded and displayed on the app page
9, take a photo\/select a picture and then flash back
Small memory
Some mobile phones have horizontal and vertical screen switches when using the camera to take pictures, which may cause our app to readjust its life cycle
Workaround: Set the Activity that uses the camera function: android:configChanges=" orientation|keyboardHidden|screenSize"
10. Page layout problems
You forgot to specify orientation when you layout in LinearLayout, and there was a flash out
This indicates that the app is in the process of updating, and a flash back will occur. Or check the network to see if it has changed to 2G. Is my phone a lot of junk?
