Flutter run stuck at Installing build\app\outputs\apk\app.apk

Question

Edit: It seemed to work after restarting everything, no other solution really noticed.

I couldn't find useful solutions on following thread:

Flutter stuck at Installing build\app\outputs\apk\app.apk

It's not the same issue, mine doesn't finish installing.

I have an Honor 7 as a connected device and using Visual Studio Code.

When running 'flutter run' following happens:

Launching lib/main.dart on PLK L01 in debug mode...
Initializing gradle...                                       1,1s
Resolving dependencies...                                    3,3s
Gradle task 'assembleDebug'...
Gradle task 'assembleDebug'... Done                         15,6s
Built build\app\outputs\apk\debug\app-debug.apk.
Installing build\app\outputs\apk\app.apk...                     -

Once last step is loading, my device asks to accept app installation. Once accepted it provides 2 options after installation:

• Open App

• Finish ( Meaning = return to home screen )

Either way the last step doesn't finish. 'flutter clean' makes no difference. Hot reload not working. Did anyone else encounter this issue ?

Answer 1

Solutions is quite simple

For flutter hot reload problems that may be happening with your project,

It is a problem with your device, and not flutter or Android Studio

This happens when your logcat hangs up.

You might want to increase your buffer size.

To do this, go into your device or emulator:

Settings > Developer options (Ensure they are turned on),

Change the buffer size to a higher number.

Then run flutter run -v again

Answer 2

Other user may get solution in this url. In my case the app uninstalled manually so it is not showing in launcher . and got solution in this post.

which is

1. Go to Settings.
2. Go to Apps.
3. Select your app. (here, you can verifythat your app is not uninstalled properly).
4. Open the overflow menu (which are 3 dots)on the top right and select Uninstall for all users.

Answer 3

In my case the problem was that I forgot to change MainActivity.kt package name after I modified it.

package com.WrongCompanyName.WrongProjectName

import androidx.annotation.NonNull;
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
    }
}
