Blank page Application when change permission manually #22198

Closed rickyazhari closed 6 years ago

rickyazhari commented 6 years ago

Hi, i made porting to native function to open application info for changing permission need manually straight from the app.

Application info open as expected but when the permission value changes and back in to application. the app just showing blank page. Here reactions from 2 devices.

IOS => Back to app just show blank page after while application restart ANDROID => Back to app just show blank page and there is no other activity after that.

i try to catch with debug logging, but after back to application, debug log just said lost connection to device.

If you use flutter logs after the crash, do you get any relevant debug output?

Thanks for the bug report and the logs @rickyazhari.

I think on iOS apps are deliberately restarted by the system itself in response to permission changes. See https://stackoverflow.com/a/29707306 and https://stackoverflow.com/a/12668187 for some explanation and sources. That would explain the ########### Quitting application (com.tanamduit.ios) in response to privacy settings change. log you posted.

Android doesn't do this, so the problem you're seeing there is something else. I added a permission to the basic flutter create app, opened it, toggled the permission in Android settings, and brought the demo back into the foreground to try and test it out. Everything appears to be working fine for me. Could you post some simple example code that causes this problem on Android? Logs would be helpful too.

rickyazhari commented 6 years ago

ok i will try with sample code and thanks for explanation i thought so too about restarting application in ios. but i'll do some sample and my real apps in android. i'll post soon

rickyazhari commented 6 years ago

ok, sorry to take much time to reply,

after i do some sample in android device when redirecting to application info from apps and change permission with case : 1 . off to on : back to application is normal

  1. off to on and back off : back to application and got white blank screen.

here logs in case 2 :

My assumption base on logs. The os system is trying to restart app cause service value change than the app crash. But why it get blank white page result ?

mklim commented 6 years ago

No problem, thanks for the logs. I was mistaken earlier, looks like Android actually terminates apps in response to permissions being revoked. Sorry about that. I'm having trouble finding documentation on this, but I'm seeing it happen with my tester app too. I'm not 100% sure of this, but from what I can tell the app isn't being restarted on Android, it's just being stopped until it's opened again.

Not sure about the white screen you're seeing, and unfortunately I'm not getting any useful information from the logs to help debug it further. Could you upload some simple example code that reproduces this problem?

rickyazhari commented 6 years ago

here's i provide sample app to replicate this issue main.dart

import 'package:flutter/material.dart';
import 'package:tanamduit_porting_collections/tanamduit_porting_collections.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new InputField()
    );
  }
}

class InputField extends StatelessWidget{

  @override
  Widget build(BuildContext context){
    TanamduitPortingCollections collections = new TanamduitPortingCollections();
    return new Scaffold(
      body: new Center(
        child: new GestureDetector(
          onTap: () async{
              collections.goToSettingPermission(
                packageName: "com.example.sampleimagecache",
                request: "request"
              ); 
          },
          child: new Container(
            width: 200.0,
            height: 75.0,
            color: const Color(0xFF575757),
            child: new Text(
              "Button",
              style: new TextStyle(
                color: const Color(0xFFFFFFFF),
                fontSize: 16.0,
                fontWeight: FontWeight.w500
              ),
            ),
          ),
        ),
      ),
    );
  }
}

plugin tanamduit_porting_collections lib

Future<bool> goToSettingPermission({
    String packageName,
    String request
  }) async{
    final args = {};
    args['package'] = packageName;
    args['request'] = request;
    return await _channel.invokeMethod("goToSetting",args);
  }

porting android

@TargetApi(Build.VERSION_CODES.GINGERBREAD)
  private void goToSetting(MethodCall call){
    String pkg = call.argument("package");
    String requestSection = call.argument("request");

    if(pkg != null) {
      Intent setting = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + pkg));
      setting.addCategory(Intent.CATEGORY_DEFAULT);
      vAct.startActivityForResult(setting,100);
    }else {
      vResult.error("Invalid Package name", "Pckage name not found", null);
    }
  }

porting ios

-(void) goToSetting :(FlutterResult)result{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
    result(@YES);
}

thanks for your help

mklim commented 6 years ago

Thanks for the code!

So unfortunately I'm still not seeing the issue. How are you populating vAct and vResult in the Android example plugin? I'm using this:

  TanamduitPortingCollections(Activity activity) {
    this.vAct = activity;
  }

  /** Plugin registration. */
  public static void registerWith(Registrar registrar) {
    final MethodChannel channel = new MethodChannel(registrar.messenger(), "test_plugin");
    channel.setMethodCallHandler(new TestPlugin(registrar.activity()));
  }

  @Override
  public void onMethodCall(MethodCall call, Result result) {
    vResult = null;
    if (call.method.equals("goToSetting")) {
      vResult = result;
      goToSetting(call);
    } else {
      result.notImplemented();
    }
  }

I'm seeing the app reload when I navigate back to it from the permissions screen after disabling the permission, but it is reloading correctly and drawing the button again instead of hanging.

rickyazhari commented 6 years ago

Sorry for late reponds hmm interesting. in application settings, did you change permission value from off to on and then change again to from on to off. In my case i've got blank page result. i will provide some gift.

rickyazhari commented 6 years ago

Ok, i do some test with my apps. it seems not blank screen anymore. i confirmed android os restarting the application cause changing permission service. We can close this issue thanks for keep patience and your support.

keep up the good work

mklim commented 6 years ago

Glad it's been resolved for you. Thanks for reaching out!
