android -------- java.net.UnknownServiceException

由 我的梦境 提交于 2021-02-19 01:58:30
最近升级了Android的API版本时 ，导致我的网络请求失败了， 出现了这个错误 java.net.UnknownServiceException， 这个错误，我在网上查到这个主要是由于，我们的OkHttp3会默认使用密文传输，而我们的代码中使用Http协议，也就是使用明文传输，所以OkHttp3会主动的报错，然后阻止线程的运行。所以我们现在就是要修改配置文件，使OkHttp3允许使用明文传输，或者我们直接使用Https协议。 解决方法： 在 res 下新建一个 xml 目录，然后创建一个名为：network_security_config.xml 文件 该文件内容如下： <?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config cleartextTrafficPermitted="true" /> </network-security-config> 然后在 AndroidManifest.xml application 标签内应用上面的xml配置： <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android

How to install specific TTS engine programmatically in Android?

由 青春壹個敷衍的年華 提交于 2021-02-19 01:30:25
问题 I am trying to add to my app specific TTS engine - not system based, so each person will have another, but one for all. In documentation there is method:setEngineByPackageName(), which looks like it will make what I want.
