https遇到自签名证书/信任证书

对于CA机构颁发的证书Okhttp默认支持 可以直接访问 但是对于 自定义 的证书就不可以了（如：https : //kyfw.12306.cn/otn/ ）， 需要加入Trust 下面分两部分来写，一是信任所有证书，二是信任指定证书，访问自签名的网站 一、信任所有证书 1. 在你的module 下 build.gradule里添加 dependencies { 、、、 compile 'com.zhy:okhttputils:2.6.2' 、、、} 2.新建MyApplication public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); // 这就是信任所有证书 HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(null,null, null); OkHttpClient okHttpClient = new OkHttpClient.Builder() .connectTimeout(10000L, TimeUnit.MILLISECONDS) .readTimeout(10000L, TimeUnit.MILLISECONDS)

How to handle SAF when I can only handle File or file-path?

由 落花浮王杯 提交于 2021-02-19 02:43:06
问题 Background Up until Android Q, if we wanted to get information about an APK file, we could use WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE to get access to the storage, and then use PackageManager.getPackageArchiveInfo function on the file-path. Similar cases exist, such as using ZipFile class on a compressed file, and probably countless framework APIs and third party libraries. The problem Google announced a huge amount of restrictions recently on Android Q. One of them is called Scoped

How to properly approach threading with Room

由 泄露秘密 提交于 2021-02-19 02:39:59
问题 I am confused about Room and can not find an answer in the documentation. So, the library enforces using queries on a separate Thread, which is understandable. However, it seems that Delete queries are not included in this limitation and can be freely called from the UI Thread. They also always return a raw output value, without a chance to wrap it in an Observable. What is the correct way to use the delete call in Room then ? Should it be run on a separate Thread? If not, what about

So, is there a way to route all the traffic of the App through a proxy (when available), like any library or some
