Android Configuration

Setting up Android for your Frezka Project

Open Android Module

• The Android module can be accessed in Two ways:

1. Select the Android Module from the same project you're attempting to open by going to File -> Open.

   

2. Navigate to Tools -> Flutter -> Android Studio -> Open Android Module.

   

Change The Application Id

IMPORTANT

Every Android app has a unique application ID that looks like a Java package name, such as com.example.myapp. This ID uniquely identifies your app on the

device and in the Google Play Store. Once you publish your app, you should never change the Application ID.

• For Application ID, change the applicationId in the build.gradle file at the app level.
• Locate the build.gradle file at this path: android/app/build.gradle.

defaultConfig {
    applicationId "YOUR_PACKAGE_NAME"
    minSdkVersion 21
    targetSdkVersion 31
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Change The Version Name

IMPORTANT

The version name is a string value that represents the "friendly" version name displayed to the users. The version name is displayed to the user.

• For Version Name, change the versionName in the build.gradle file at the app level.
• Locate the build.gradle file at this path: android/app/build.gradle.

defaultConfig {
    applicationId "com.iqonic.example"
    minSdkVersion 21
    targetSdkVersion 31
    versionCode 1
    versionName "CHANGE_THE_VERSION_NAME"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Change The Version Code

IMPORTANT

The version code is an incremental integer value that represents the version of the application code. The version code is used by the Google Play Store for

new updates. If you increase the version code, the update will be visible to all users.

• For Version Code, change the versionCode in the build.gradle file at the app level.
• Locate the build.gradle file at this path: android/app/build.gradle.

defaultConfig {
    applicationId "com.iqonic.example"
    minSdkVersion 21
    targetSdkVersion 31
    versionCode "CHANGE_THE_VERSION_CODE"
    versionName "1.0.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Change The App Name From Manifest File

IMPORTANT

To change the name of your Android application in Android Studio, you have to change the value of the property android:label defined inside the <application> node in AndroidManifest.xml.

<application
    android:label="YOUR_APP_NAME">
</application>

Change The App Icon

IMPORTANT

Android Studio includes a tool called Image Asset Studio that helps you generate your own app icons from material icons, custom images, and text strings. It generates a set of icons at the appropriate resolution for each pixel density that your app supports. Image Asset Studio places the newly generated icons in density-specific folders under the res/ directory in your project. At runtime, Android uses the appropriate resource based on the screen density of the device your app is running on.

Image Asset Studio helps you generate the following icon types:

• Launcher icons Adaptive & Legacy
• Legacy Launcher Icon
• Action bar and Tab Icons
• Notification icons
• Tv Banner
• Tv Channel Icon

For More Details You can checkout Android Studio Editor Guide for creating Android Icons.
