Trusting all certificates with okHttp

由 半城伤御伤魂 提交于 2019-11-26 19:22:28
For testing purposes, I'm trying to add a socket factory to my okHttp client that trusts everything while a proxy is set. This has been done many times over, but my implementation of a trusting socket factory seems to be missing something: class TrustEveryoneManager implements X509TrustManager { @Override public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException { } @Override public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException { } @Override public java.security.cert

Android, How to handle change in network (from GPRS to Wi-fi and vice-versa) while polling for data

由 杀马特。学长 韩版系。学妹 提交于 2019-11-26 16:02:20
问题 I use DefaultHttpClient and HttpGet to poll data from server. Now, say a user was in Wi-fi network and moves out of the room. So the phone automatically starts using the 3G network. Are there any call-backs for such change, and how should I handle such changes. Should I start polling again or does the OS take care to make the changes appropriately 回答1: You can set up a Receiver in your manifest: <receiver android:name=".NetworkChangeReceiver" android:label="NetworkChangeReceiver"> <intent

Volley and AsyncTask

由 邮差的信 提交于 2019-11-26 15:43:32
问题 I read a post about Volley and I know it's great networking library. But I couldn't understand one thing. All requests are Async Task or not? When I want to send asyncTask request using Volley do I need put Volley request in AsyncTask? or should I just call Volley Request if it is already AsyncTask request? private class MyClass extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... params) { // do Volley request } } Is this right approach? 回答1: You don

How to determine if network type is 2G, 3G or 4G

由 守給你的承諾、 提交于 2019-11-26 14:13:16
I have an indicator on my application to display the network type (2G or 3G or 4G) but after getting the network type, how do I know what speed category it should be in? I know how to detect the network type: private TelephonyManager telephonyManager; telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); CurrentNetworkType = telephonyManager.getNetworkType(); Given the possible return values: // public static final int NETWORK_TYPE_1xRTT // Since: API Level 4 // Current network is 1xRTT // Constant Value: 7 (0x00000007) // // public static final int NETWORK_TYPE

Google Cloud Messaging - messages sometimes not received until network state changed

由 大憨熊 提交于 2019-11-26 08:03:36
问题 While working on a little project that integrates with GCM, I\'ve stumbled across a bit of a strange issue. Some times when I start watching the log to see if messages are received, messages do not appear to be coming through until I have changed the network state (I.E. originally on WiFi, if I turn off WiFi and move to Mobile Data, the messages arrive fine). After I\'ve changed the network state, messages start to arrive perfectly fine, and the same applies once I change the network state

Volley Android Networking Library

由 江枫思渺然 提交于 2019-11-26 06:10:19
问题 I have few questions around using Volley in my projects: Can this library be used in any Java project or just Android? I see multiple branches here and no documentation on which branch is to start with. Which branch should I use to start with? How do you integrate this library in your own project? What approach is better: Make Volley as a standalone library project and spin a jar and put it in your project or copy the all source code inside your project? 回答1: $ git clone https://android
