If you are facing errors building your Android application after updating Pushwoosh Flutter Plugin to version 2.1.0 or higher, please search this guide for the error you encountered and follow the instructions to fix it.

Build error: Google Play services dependency conflict

In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[17.0.0, 18.0.99]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Solution:

Add this line to your app/build.gradle file:

googleServices { disableVersionCheck = true }

Build error: minCompileSdk Mismatch

The minCompileSdk (30) specified in a dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties) is greater than this module's compileSdkVersion (android-29).

Solution:

Update compileSdkVersion in your app/build.gradle file:

android {
    compileSdkVersion 30
    ...

Build error: Unexpected queries element in Manifest

AAPT: error: unexpected element <queries> found in <manifest>.

Solution:

Update gradle plugin in your project. To do this, open PROJECT_DIR/build.gradle and update gradle plugin version to version 4 or higher:

classpath 'com.android.tools.build:gradle:4.1.2'

In PROJECT_DIR/gradle/wrapper/gradle-wrapper.properties, update gradle wrapper version:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

Build error: Missing transform input file

    lintOptions {
        disable 'InvalidPackage'
    }

to this:

    lintOptions {
        checkReleaseBuilds false
    }
