Trying to use Firestore in my project. My project is a brand new one, but having problems running the app on my device without getting an error: Execution failed for tas
You can follow the guidelines mentioned here
https://developer.android.com/studio/build/multidex
or to cut the story short and directly go to answer
Find android/app/build.gradle
file and add the following lines of codes:
dependencies {
compile 'com.android.support:multidex:1.0.3'
//find latest version from here https://developer.android.com/studio/build/multidex
}
android {
defaultConfig {
multiDexEnabled true
}
}
The problem is with multidex builder. Actually, this often happens when you have imported a lot of packages in your yaml file which cannot fit into a single .dex built hence you have to enable multidex.
Go to android/app/build.gradle and add the following lines of codes:
dependencies {
implementation 'com.android.support:multidex:1.0.3' //enter the latest version
}
android {
defaultConfig {
multiDexEnabled true
}
}
Fixed the issue, but don't understand why. Why do I need to enable multiDex when I believe Firestore is using AndroidX?
Anyway, the fix. Add multiDexEnabled true to your app/build.gradle
defaultConfig {
// TODO: Specify your own unique Application ID
(https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.poll"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
//This line here...
multiDexEnabled true
}
When your app and the libraries it references exceed 65,536 methods, you encounter a build error that indicates your app has reached the limit of the Android build architecture: https://developer.android.com/studio/build/multidex
add multiDexEnabled true in app/build.gradle defaultConfig at last.
defaultConfig{ ... multiDexEnabled true }
I just met with this error, and it turns out it can be fixed easily. Of course, other answers on this are really great and it tells you how to fix it. However, I was wondering why this even happened. It turns out this comes from the minSdkVersion
used. If this is set to 20
or lower, you need to configure your app for multiDex support.
defaultConfig {
applicationId "com.inspire.aaym"
minSdkVersion 21
targetSdkVersion 30
}
So, if you app is not intended to be used in Android version prior to 5.0, setting the minSdkVersion
number to 21
will easily fix this issue. If not, follow the workaround to enable mutiDex support.

If you are using AndroidX,
Add below lines to app/build.gradle
multiDexEnabled true // to the defaultConfig {}
implementation 'androidx.multidex:multidex:2.0.1' // to the dependencies
To the AndroidManifest.xml (Optional)
<application
android:name="androidx.multidex.MultiDexApplication"
Please note that you have to extends MainActivity
to the MultiDexApplication
. If you change android:name
.
