How to use

Add to Project

Gradle

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

dependencies {
  implementation 'com.github.mncinnovation:mnc-android-code-standard-core:0.1.3'
}

or Maven

<repositories>
  <repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
  </repository>
</repositories>

<dependency>
  <groupId>com.github.mncinnovation</groupId>
  <artifactId>mnc-android-code-standard-core</artifactId>
  <version>0.1.3</version>
</dependency>

Implementation

1. BaseActivity

class MainActivity : BaseActivity() {
    private lateinit var binding: ActivityMainBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        showToolbarBack(false)
        showToolbarTitle(false)
    }
}

2. BaseViewModel

• Handle Result from com.mncgroup.core.network.Result (To Handle result from any data model)
• Common live event, like _isLoading, showErrorDialog, navigateToLogin and more.

class LoginViewModel constructor(
    private val authRepository: AuthRepository,
    userRepository: UserRepository
) : BaseViewModel() {

    val userData: LiveData<List<UserModel>> = userRepository.getUserLiveData()

    @OptIn(DelicateCoroutinesApi::class)
    fun authLogin(email: String, password: String) {
        _isLoading.value = true
        GlobalScope.launch(Dispatchers.Main) {
            val result = authRepository.requestLogin(LoginRequest(email, password))
            result.handle {
                //handle result ok
                _isLoading.value = false
            }
        }
    }
}

3. WebViewActivity, an activity class to show webview. You can use WebViewActivity directly from your project.

    val headers: MutableMap<String, String> = mutableMapOf()
   headers["token"] = "5454wvybw9y9"
   startActivity(
       Intent(this@MainActivity, WebViewActivity::class.java)
           .apply {
               putExtra(EXTRA_TITLE, "Webview")
               putExtra(EXTRA_HEADERS, headers.toMap() as Serializable)
               data = Uri.parse("https://cloud.google.com/speech-to-text/docs/libraries")
           }
    )

4. Load Image

Easy load image by accessing ImageView extensions.

    ivImage.load("https://img.shields.io/github/v/release/mncinnovation/mnc-android-code-standard-core.svg?label=latest")

5. Snackbar

    btnShowSnackbar.setOnClickListener {
    showSnackbar(it, "Ini snackbar") {
        Toast.makeText(this@MainActivity, "closed snackbar", Toast.LENGTH_SHORT).show()
    }
}

6. Intens

There is an Intents object that contain functions that return Intent

    btnOpenLocationSetting.setOnClickListener {
    startActivity(Intents.createOpenLocationSettings())
}

7. AppCompatAlert

Show appCompatAlert or with action, or with input action.

    btnShowAppCompatAlertAction.setOnClickListener {
    showAppCompatAlert("This is a message") {
        Toast.makeText(this@MainActivity, "Test", Toast.LENGTH_SHORT).show()
    }
}

8. Date Picker and Date utils

   btnShowDatePicker.setOnClickListener {
    showDatePickerAction(null, null) { day, month, year ->
        Toast.makeText(
            this@MainActivity, "selected date is " + day +
                    " / " + month +
                    " / " + year, Toast.LENGTH_SHORT
        ).show()
    }.show()
}

Calendar extensions

• Calendar.getDate()
• Calendar.getMonth()
• Calendar.getFullYear()
• Calendar.getHours(), Calendar.getMinutes(), Calendar.getSeconds(), Calendar.getMilliseconds()
• DateFormat.parseIndonesianCalendar(dateString: String): Calendar

Date Format with indonesian Locale variable

9. Permissions

Check any permissions and request permissions.

    private fun checkPermissionOrOpenCamera() {
    when (checkPermissionsAll(
        listOf(
            Manifest.permission.CAMERA,
            Manifest.permission.WRITE_EXTERNAL_STORAGE
        )
    )) {
        PermissionResult.Granted -> openFileChooser()
        PermissionResult.DialogNeeded, PermissionResult.NeedRequest -> {
            requestPermissions(
                RC_CAMERA,
                Manifest.permission.CAMERA,
                Manifest.permission.WRITE_EXTERNAL_STORAGE
            )
        }
    }
}

10. Internet Util

This is an object to help app check internet connection. First need to init in application class.

class AppNameApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        //init internet util
        InternetUtil.init(this)
    }
}

And to use it call runIfConnectedOrResultException and place call of function API at the body like this sample.

interface AuthRepository {
    suspend fun requestLogin(request: LoginRequest): Result<LoginResponse>
}

class AuthRepositoryImpl(private val authApi: AuthApi, private val userRepository: UserRepository) :
    AuthRepository {
    @OptIn(ExperimentalCoroutinesApi::class)
    override suspend fun requestLogin(request: LoginRequest): Result<LoginResponse> {
        return runIfConnectedOrResultException {
            authApi.loginUser(request).awaitResult() {
                userRepository.updateUser(this.user)
                this
            }
        }
    }
}

11. View Extensions

Common functions for view configurations.

• View.hideKeyboard() and View.showKeyboard()
• View.toBitmap()
• Boolean?.toVisibleOrGone()
• Boolean?.toVisibleOrInvisible()
• Context.dip(value: Int)

12. Arguments

Start an Activity for given class T and allow to work on intent with "run" lambda function

• <T : Fragment> T.withSerializable(vararg arguments: Pair<String, Serializable>)
• <T : Fragment> T.withParcelable(vararg arguments: Pair<String, Parcelable>): T

Retrieve property from intent

• <T : Any> AppCompatActivity.argument(key: String) : T
• <T : Any> AppCompatActivity.argument(key: String, defaultValue: T? = null) : T
• <T : Any> AppCompatActivity.argumentNotNull(key: String, defaultValue: T) : T
• <T : Any> Fragment.argument(key: String) : T
• <T : Any> Fragment.argument(key: String, defaultValue: T? = null) : T
• <T : Any> Fragment.argumentNotNull(key: String, defaultValue: T) : T

13. ConfigUtils

Configuration for resources locale

• Context.updateResourcesLocale(locale: Locale): Context
• Context.updateResourcesLocaleLegacy(locale: Locale): Context
• Context.updateBaseContextLocale(locale: Locale): Context
• Context.updateResourcesLocale(body: Configuration.() -> Unit): Context
• Context.updateBaseContextLocaleWithoutChange(locale: Locale): Context
