Problem 1 android cannot send a network request

A problem with cordova when packaging android is that it cannot send a request (whether it's http or https) after packing. In the end, the original project was deleted and then a new one was built.

Question 2 build android reported an error

Cordova reported an error when packaging with cordova build android after installing the cordova-plugin-image-picker plug-in

Report in the file * *\ ImageFetcher.java:294 that Entry is not public in LinkedHashMap and cannot be accessed from an external package. Protected boolean removeEldestEntry (LinkedHashMap.Entry eldest) {

The final solution is to first introduce the class package import java.util.Map into ImageFetcher.java, and then go to line 294 of the file, which is the location of the code shown in the error above, and modify the code as follows

Protected boolean removeEldestEntry (Map.Entry eldest)... / / the following code will be omitted.

Then save it and cordova build android it again to be successful.

Question 3 gradle version problem

When packing, sometimes the error will be as follows

Minimum supported Gradle version is 4.6. Current version is 4.1If using the gradle wrapper try editint the distributionUrl in * *\ gradle-wrapper.properties to gradle-4.6-all.zip

As can be seen from the above information, the version of gradle we currently support is 4.6, but we are currently using 4.1. So we need to upgrade. The upgrade is actually very simple. Find the 227th line in the platform/android/cordova/lib/builders/StudioBuilder.js file and change the following gradle-4.1-all.zip to gradle-4.6-all.zip. Then cordova build android can be executed normally.
