Problem Description
How to troubleshoot if the page is stuck on the Loading (three blue dots) page when the APP starts the mPaaS applet?
Common cause
Accessing UC SDK in Android applications can effectively solve the compatibility problems of browsers of various manufacturers, maintain a lower crash rate than system browsers and have better performance. UC SDK provides security support to solve security risks in a timely manner; using the UC kernel can enable small programs to have the same layer capabilities, such as embedding webview, embedding maps, etc., and have a better rendering experience.
To use the applet, you must apply for the UC kernel , obtain the UC kernel key by submitting a work order , and configure the relevant parameters in AndroidManifest.xml.
Troubleshooting ideas
There are generally two reasons: one is the path to the homepage of the applet , and the other is the lack of uc kernel .
1. Check whether the UC kernel is effective
Run the APK on the phone and check the Log log to verify whether the UC kernel has taken effect. Filter webview version in logcat log of Android Studio.
As shown in the figure below, under normal circumstances:
- The version number (version) starting with 2 or 3 is the UC kernel.
- The kernel starting with Chrome is the system kernel.
2. Check whether the main entry path of the applet is correct
The main entrance of the applet must be consistent with the main entrance in the mPaaS console; the default main entrance of the console is pages/index/index
Work order assistance
If the problem still cannot be solved, please prepare the demo project to reproduce the related problem, and contact the mPaaS after-sales technical support through the Alibaba Cloud work order system.
