Stuck at Installing build\app\outputs\apk\app.apk...

[wyxcoder]

I used to use 1.2.1, it worked fine and nice. Since a few days ago, I got 'keep stopping'. Then I tried to use the most up to date version and need add a new MyApplication.

But with it, I cannot start the app, it stuck at Installing build\app\outputs\apk\app.apk..., any idea?

[johnny-stevie]

in android manifest.xml change
android:name=".DemoApplication"
to
android:name="io.flutter.app.FlutterApplication"
The problem is that the line above is the one that starts the application.
See if that will help, it helped me when I reached that problem.

[johnny-stevie]

Scrap that, I have found out that that you need to put the MyApplication file under your project dir like com.xxx.xxx. This makes it work as thats where build.gradle goes to to start your app.
Whats your MyApplication code, just out of interest?

My project also had this problem. I thought Android build functionality had failed, but I didn't know how to get it working again.

[johnny-stevie]

@xiongjianchang Did you figure it out?

[xiongjianchang]

@johnny-stevie @wyxcoder
My problem has been solved.

1. Select 'File > Open... ',
2. Navigate to your Flutter app directory, select the 'android' folder inside, and click 'OK' to open an android project.
3. Select 'File > invalidate caches/restart... '.
   Wait until the project is rebuilt and ready to use.

I got the same problem, changing the android:name to .DemoApplication makes the build stuck,
changing the android:name to the default value, when I try to make a download crashes de app without any error message.

[RafaelR7]

I was able to build the apk, in the DemoApplication.java insert at the beginning package of your project ie: io.com.hellorword;,

[johnny-stevie]

So you were missing a java import package statement?
I realised for my project that I had to write my DemoApplication in kotlin instead of java which was the whole reason why it didn't work.
Good to know you've solved your issue.
Anybody else reading this with a problem similar to mine, remember, CHECK which language your android folder uses!!!

[RafaelR7]

@johnny-stevie Yes, I was missing the package import, I just realise that by looking into the example, the readme of the package is missing this import.

take a look at the example, and compare it with your project, because the example is working.
It might help, that's what I did.

[johnny-stevie]

For me the problem was that it had to be implemented in Kotlin instead of Java. Check which language you have to setup the package in.

@HassanDev13

I just fixed my crash by including package declaration above imports. If you just copy and paste the readme it won't work because it is missing.

package com.github.sethchhim.example

import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import io.flutter.plugins.GeneratedPluginRegistrant
import vn.hunghd.flutterdownloader.FlutterDownloaderPlugin

Hope this helps.

[hnvn]

See #214 (comment)

[HassanDev13]

the problem still exists
I noticed the GeneratedPluginRegistrant class of Exemple is different with my project any idea?

[hnvn]

delete your android folder and run this command to re-generate it.

flutter create -a java .

[HassanDev13]

i run this command and he show me :
No option specified for the output directory.
Create a new Flutter project.
If run on a project that already exists, this will repair the project, recreating any files that are missing.

Usage: flutter create
-h, --help Print this usage information.
--[no-]pub Whether to run "flutter pub get" after the project has been created.
.
.
.
.
--project-name The project name for this new Flutter project. This must be a valid dart package name.
-i, --ios-language [objc, swift (default)]
-a, --android-language [java, kotlin (default)]
--[no-]androidx Generate a project using the AndroidX support libraries
(defaults to on)
Run "flutter help" to see global options.

[hnvn]

flutter create -a java .

There'a dot sign at the end of the command, it's a part of the syntax, not a typo error
