Answer 1

I hit this problem when I commented all my bitmaps in launch_background.xml:

<!-- You can insert your own image assets here -->
<item>
<!--
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_320x480" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_480x320" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_480x800" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_800x480" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_720x1280" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_1280x720" />
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_1280x1920" />            
    <bitmap
        android:gravity="center"
        android:src="@mipmap/launch_1920x1280" />  
-->          
</item>

I uncommented the bitmaps to get the Flutter build to run. I'm on:

Flutter (Channel beta, v1.0.0, on Mac OS X 10.13.6 17G4015, locale en-US)

Answer 2

I had this problem after I changed the package name. I fixed it by using this guide

In my case I did not have the java files as described in the article but did need to change the kotlin path similarly to the java path described.

Answer 3

For anybody reading this, I solved this by doing the following:

1. Open Android Studio->SDK Manager and install API 27 (By default Android Studio only installed the latest (API 28) as at the time of writing and there seem to be issues with using that right now).
2. In cmd run flutter doctor --android-licenses and make sure you accept all the licenses.
3. Open Android Studio->AVD Manager and create a new emulator using API 27
4. Run your app on the new emulator and enjoy!

Hope this helps :).

Answer 4

I fixed it:

1. Power off & Close Android Emulator
2. Reopen Android Studio & go to Tools/ AVD Manager
3. In Virtual Devices List, click Dropdown icon > select 'Wipe Data'. Then click 'Launch this AVD...'
4. Waiting for VD open, then click Run in Android Studio

good luck

Answer 5

Running flutter clean solved this issue for me using an emulator.

I wiped the emulator data, deleted my emulator, and created a new one, none of that worked. flutter clean worked though.
