amap_base regarded as scores relatively high, but the authors have not been busy updating more problems

1, will generate a keystore file into the root directory. Reference https://blog.csdn.net/weixin_44567104/article/details/90377912

2, the file generating keystore.properties adding configure

= storePassword XXX 
keyPassword = XXX 
keyAlias = XXX 
# Here is loaded under build.gradle app, android.keystore the parent directory is the root directory 
StoreFile = .. / android.keystore

3, app added under configuration build.gradle

// the Load the keystore configuration signature, maps, payment and other services to be used in 
DEF keystorePropertiesFile = rootProject.file ( " keystore.properties " ) 
DEF keystoreProperties = new new the Properties () 
keystoreProperties.load ( new new FileInputStream (keystorePropertiesFile)) 

Android { 

    .. . 
    
    @ signature profile 
    signingConfigs { 
        Debug { 
            keyAlias keystoreProperties [ ' keyAlias ' ] 
            keyPassword keystoreProperties [ ' keyPassword ' ] 
            StoreFile File (keystoreProperties [ 'storeFile'])
            storePassword keystoreProperties['storePassword']
        }
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
        profile {
            initWith debug
        }
        debug {
            signingConfig signingConfigs.debug
        }
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.release
        }
    }

}

4, modify AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<!--包名必须和build.gradle里的applicationId一致-->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="xxx">

    <!-- The INTERNET permission is required for development. Specifically,
         flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.CAMERA" />

    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->
    <application
        Android: name = "io.flutter.app.FlutterApplication" 
        Android: label = "flutter_module" 
        Android: icon = "@ mipmap / ic_launcher" > 
        <-! Android configuration amap key, ios incoming AMap.init during initialization ( 'ioskey') -> 
        < Meta-Data
             Android: name = "com.amap.api.v2.apikey" 
            Android: value = "Key"  /> 
        ! <- after the package name change default here will find .MainActivity not -> 
        < Activity

            Android: the launchMode = "singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if

                 defined in @style/LaunchTheme). -->
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

5, some problems have not been signed are basically experience, sha1 and must be on the corresponding packagename, android project configuration should be consistent
