[MIUI-Android]The widget’s Hyperlink cannot open the URL #1514

jiqi136 · 2020-11-07T03:12:40Z

Describe the bug:

The official example generated [Android] APK can not open the URL link
https://github.com/fyne-io/fyne/tree/master/cmd/fyne_demo

I tried each of the following methods, but URL opening failed

=======

`
package main

import (
"net/url"
"log"
"os"
"fyne.io/fyne/app"
"fyne.io/fyne/widget"
)

func main() {
var giturl= "http://github.com"

log.Println("----mo一一Command ， -----》")	
mo一一Command(giturl)

var Newapp = app.New()
var myWindow = Newapp.NewWindow("url") 

var git, _ = url.Parse(giturl)
_ =Newapp.OpenURL(git)

var widgeturl= widget.NewHyperlink("giturl",git)

myWindow.SetContent(widgeturl) 
myWindow.Show()
Newapp.Run()

}

func mo一一Command(giturl string){
var cmd1 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","--user", "0","-d", giturl)
var cmd2 = exec.Command("/system/bin/am", "start", "-a", "android.intent.action.VIEW","-d", giturl)
var cmd3 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-d", giturl)
var cmd4 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-c","android.intent.category.BROWSABLE","-d", giturl)
var cmd5 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-c","android.intent.category.DEFAULT","-d", giturl)
var cmd6 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-c","android.intent.category.BROWSABLE","-d", giturl,"org.mozilla.firefox")
var cmd7 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-c","android.intent.category.DEFAULT","-d", giturl,"org.mozilla.firefox")
var cmd8 = exec.Command("am", "start", "-a", "android.intent.action.VIEW","-d", giturl,"com.android.browser")

for _, cmd := range []*exec.Cmd{cmd1,cmd2,cmd3,cmd4,cmd5,cmd6,cmd7,cmd8} { 
	cmd.Stdin, cmd.Stdout, cmd.Stderr = os.Stdin, os.Stdout, os.Stderr
	var err=cmd.Run()
	if err != nil {
		//No error report
		log.Println("err",err) 
	}
}
return

}`

Can you please provide the errors that were encountered?
You should not need any permissions to access that function, but perhaps your version of android does not ship "am".
Can you also please provide more information about your device? There are many differences possible inside the "Android 4.4" umbrella.

jiqi136 · 2020-11-09T12:57:13Z

@andydotxyz
The tested Redmi 2 mobile phone is Android version 4.4. Because the mobile phone driver cannot be installed on the computer, adb cannot connect to the mobile phone and cannot get the record information of the error reason.

The "am" function can be used on the mobile phone, and the "am" function can be used to successfully create folders and delete files.
But the "am" command is invalid when opening files, devices or other applications. It seems to be limited to the set permissions.

To traverse, use the previous source code "am" command, which is "err== nil".

var err=cmd.Run()

if err != nil {

No error report}
`

andydotxyz · 2020-11-09T14:49:50Z

I cannot replicate this issue, so I am asking for your help.
What is the output of your println? log.Println("err",err)

jiqi136 · 2020-11-09T15:27:38Z

@andydotxyz

"Am" runs without error, "err == nil".
But the "am" command is invalid when opening files, devices or other applications.

andydotxyz · 2020-11-09T15:55:44Z

There must be some indication of it not working... if error is nil then perhaps there is some info on StdErr or StdOut?

stuartmscott · 2020-11-09T16:39:24Z

Because the mobile phone driver cannot be installed on the computer, adb cannot connect to the mobile phone and cannot get the record information of the error reason.

This issue should be fixed first - we cannot help diagnose the error without knowing why it is breaking. Can you try with android emulator?

var git, _ = url.Parse(giturl)
_ =Newapp.OpenURL(git)

You should not ignore errors like this.

After some hard work, I finally ran ABD and saved the record file.

1.The record corresponding to "am start"

stuartmscott · 2020-11-09T20:05:02Z

This is progress, now we know the actual issue is:

E/dalvikvm( 9424): ERROR: must specify non-'.' bootclasspath

Is this using a physical device or the android emulator?

jiqi136 · 2020-11-09T20:12:45Z

@stuartmscott
Real Android phone operation and finger click operation

stuartmscott · 2020-11-09T20:21:25Z

Try with the emulator so we know whether it is an issue with your device or not

jiqi136 · 2020-11-12T15:49:18Z

@stuartmscott

I tried the latest mobile phones of three brands, and they all worked and opened the website.

VMware virtual machine is equipped with Android-x86-5.1-rc1.iso, although it crashed in the end,
But the URL was successfully opened before the crash.（var err=Newapp.OpenURL(git)）

andydotxyz · 2020-11-12T19:43:53Z

What is special about this device I wonder? What is the manufacturer/model and are there any operator-customisations loaded?

jiqi136 · 2020-11-13T03:21:05Z

@andydotxyz

Mobile phone name: Hongmi mobile phone
Mobile phone model: HM2a
Android version: 4.4.4KTU84Q
MIUI version: MIUI9.2

andydotxyz · 2020-11-14T10:21:49Z

Ah, so the MIUI is not really Android I think.
The classpath configuration may be incompatible with certain standard actions - and it looks like "am" is one of those things that does not work.
I guess we need to see if there is an Android API that MIUI still supports that we can use instead

donatj · 2020-12-14T22:23:52Z

For what it's worth I am having the same problem on my Google Pixel 4a XL

donatj · 2020-12-14T22:33:09Z

url, _ := url.Parse("https://www.google.com")
err := fyne.CurrentApp().OpenURL(url)
fmt.Println(err);

gets me

exit status 255

andydotxyz · 2020-12-20T11:14:53Z

That is very helpful thank you @donatj.

Is it possible for you find the appropriate entry in your android log?
Before the 255 exit there should be output printed. This content will be in the Android log (adb logcat) with a Fyne or Go prefix...

stuartmscott · 2021-02-19T16:18:16Z

I just hit this too on Pixel 2 w/ Android 11 (though not using a widget.Hyperlink, instead using a widget.Button that calls app.App.OpenURL, but I think the widget is irrelevant to this bug);

Nevermind, android:exported="true" is for an application to indicate that IT can be launched by others.

Sorry for the false positive.

donatj · 2021-02-19T17:14:55Z

Finally figured out how to use logcat (sorry, I'm not primarily an Android dev)

Would it be possible to run a simple app on one of these devices to launch it using the activity API like this:
https://stackoverflow.com/questions/2201917/how-can-i-open-a-url-in-androids-web-browser-from-my-application

That might help track down if it is solvable by removing dependency on the helper tool we invoke.
