danikula opened this issue 7 years ago · comments

In some cases local server cache proxy is not pinged. One known problem is system proxy in connection's settings (wi-fi or apn).
May be some another reasons exist.
Typical stacktrace is

Since #28 fixed by this commit it should be fixed too.

Hi. Using AndroidVideoCache version 2.7.0 I saw the log below, so here I am, reporting as asked :) Hope it helps somehow.

I was testing using AndroidVideoCache inside recyclerview rows to pre-load audio and video. Scrolling between a lot of items very fast, around list position 650 the log stack traces appeared:

after many days of frustration I managed to find something: NanoHttpd/nanohttpd#270 (comment),
as MrStanaland said, Mint is causing this, at least in my case, now it works for me 👍

Mint.disableNetworkMonitoring();
Mint.initAndStartSession(context, BuildConfig.MINT);

I saw this log when I connected to Wifi which has no Connection to Internet

AND
If I close both wifi and cell data, your proxy can not provider cached res.

Alex Kong · Answer 15 · Sat Sep 01 2018 13:44:55 GMT+0800 (China Standard Time)

Was getting this issue using the Android emulator. Turns out it was because Android P by default blocks cleartext support for HTTP calls, so if you're using 127.0.0.1 or something like that for your proxy, it'll be blocked. You can add exceptions for certain domains to get around that. Not sure if this helps anybody else.

In my case the issue is the target version you have chosen for your android application. if it's android 9.0 or higher it will not work with legacy applications.

I simply resolved it by adding
<uses-library android:name="org.apache.http.legacy" android:required="false" />
under my <application> in AndroidManifest.xml

Because server try to make an http request instead of an https request.

I have the same issue.

mdeora · Answer 37 · Wed Sep 25 2019 20:57:22 GMT+0800 (China Standard Time)

Same issue, its because of using http url for ping instead of https.

mdeora · Answer 38 · Wed Sep 25 2019 20:57:40 GMT+0800 (China Standard Time)

can we change the ping to https? Since you are pinging localhost should be possible?

Doniyor · Answer 40 · Fri Nov 22 2019 06:22:45 GMT+0800 (China Standard Time)

In my case the issue is the target version you have chosen for your android application. if it's android 9.0 or higher it will not work with legacy applications.

I simply resolved it by adding
<uses-library android:name="org.apache.http.legacy" android:required="false" />
under my <application> in AndroidManifest.xml

Because server try to make an http request instead of an https request.

this helps for me too, thanks)

hey! i had this issue in Api 29 lib version 2.7.1. The problemis the http protocol in proxy settings, this will be https for new versions of android.
I fix it add new xml file for networkconfig:
<network-security-config> <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true">127.0.0.1</domain> </domain-config> <base-config cleartextTrafficPermitted="true"> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config >

and add this configuration to application node
<application android:networkSecurityConfig="@xml/network_config" ...

sorry by my poor english, enjoy! and thanks so much for library ;)

1.add android:usesCleartextTraffic="true" into AndroidManifest.xml application;
2.add android:networkSecurityConfig="@xml/network_security_config" into AndroidManifest.xml application;
3.add <uses-library android:name="org.apache.http.legacy" android:required="false" /> into AndroidManifest.xml application;

One case, when you start proxy server thread and never interrupt it, and then, if the proxy server count more than a uncertain threshold, it may cause occur ping server failed.
The correct way to do this is, when you get out of this proxy server, you need shutdown it.

Same with @nuborisar, and the solution works for the following case:

Caused by: java.io.IOException: Cleartext HTTP traffic to 127.0.0.1 not permitted

Check your android:networkSecurityConfig file, and add

<domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">127.0.0.1</domain>
</domain-config>

i have see this: when i use it:

Android Studio & Platform:

Android Studio 4.1.1
Build #AI-201.8743.12.41.6953283, built on November 5, 2020
Runtime version: 1.8.0_242-release-1644-b3-6915495 x86_64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

Android build.gradle config:

  minSdkVersion 21
  targetSdkVersion 30

  kotlinOptions { jvmTarget = '1.8' }

Phone: XIAOMI K30 (Android11, MIUI12)
The way i use it:

// i had use "ktor" to make requests to local  proxy server.
CoroutineScope(Dispatchers.IO).launch {
  ...
  var client: HttpClient? = null
  try {
      ...
     client = HttpClient(OkHttp) ...
     val statement = client.get<HttpStatement>(httpProxyCacheServer.getProxyUrl(rawUrl)) // this is (PreloadStatement.kt:53)
     ...
  }
}

other info:
i had not implementation this library derectly but use third-party library:

 implementation 'com.github.CarGuo.GSYVideoPlayer:gsyVideoPlayer-java:v8.1.3-jitpack'

i've clone this project newest and compare with that:
just some thing different:

i try to exclude third-party lib and use this:

    implementation("com.github.CarGuo.GSYVideoPlayer:gsyVideoPlayer-java:$GSY_PLAYER_VERSION") {
        exclude group: 'com.github.CarGuo.GSYVideoPlayer', module: 'gsyVideoPlayer-proxy_cache'
    }
    implementation "com.danikula:videocache:2.7.1"

but not working, and crash as if because not support https.

Finally following solution worked for me :)
add following in a xml file network_security_config inside res/xml dir
<network-security-config> <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true">127.0.0.1</domain> </domain-config> <base-config cleartextTrafficPermitted="false"> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config>

add following lines in Manifest.xml file inside application tag and outside activity
android:networkSecurityConfig="@xml/network_security_config"
