EasyPack

Install

In your root build.gradle

buildscript {
    repositories {
        google()
        mavenCentral()
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

In your module's build.gradle

dependencies {
  implementation "com.github.boybeak:easy-safr:$easy_pack_version"
  implementation "com.github.boybeak:easy-fp:$easy_pack_version"
  implementation "com.github.boybeak:easy-picker:$easy_pack_version"
}

Summary

I create a principle called WCWC, means "Where calls, where callbacks". Aimed to put calls and callbacks together.

For example, startActivityForResult is a call, but the callback is in another method onActivityResult. This breaks WCWC principle.

easy-safr: SAFR is short for startActivityForResult.

easy-fp: A helper library for FileProvider.

easy-picker: A helper library for get or capture audio, image or video content from recorder, gallery or camera. This library based on easy-safr and easy-fp.

Easy-safr

val it = Intent(this, ResultMakeActivity::class.java)
EasySAFR.startActivityForResult(applicationContext, it,
  object : OnResultAdapter {
    override fun onOk(id: String, requestCode: Int, data: Intent?) {
      Toast.makeText(this@MainActivity, "onOk", Toast.LENGTH_SHORT).show()
    }

    override fun onCancel(id: String) {
      Toast.makeText(this@MainActivity, "onCancel", Toast.LENGTH_SHORT).show()
    }
  }
)

There's no need to handle the result in onActivityResult method.

Easy-fp

FileProvider is a bit complex. Easy-fp makes it easy to use and provide a uri-to-file access.

Make a paths.xml file in R.xml res folder.

<!--R.xml.paths-->
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="files_path" path="images/"/>
    <cache-path name="my_images" path="images/" />
    <external-cache-path
        name="external_cache_path"
        path="images"
        />
</paths>

Do not repeat any one of the path items above.

If you make 2 files-path items with the same name or path, this library not suite for you.

<provider
	android:name="androidx.core.content.FileProvider"
	android:authorities="${applicationId}.fileprovider"
	android:exported="false"
	android:grantUriPermissions="true">
  <meta-data
		android:name="android.support.FILE_PROVIDER_PATHS"
		android:resource="@xml/paths" />
</provider>

Get file from uri.

val uri = ...
val file = EasyFP.guess(this, uri)

In this example, the uri must be in the R.xml.paths items.

Get uri by dir and file name.

EasyFP.withAuthority(this, "your authority")
  .cacheDir()
  .name("xyz.jpg")
  .uri()
//.file() or .uri()

Use a default FileProvider - The first FileProvider listed in manifest file.

EasyFP.withDefault(this)
  .cacheDir()
  .name("xyz.jpg")
  .pair() 
//.file() or .uri()

uri() means return uri, file means return file, pair()means return both uri and file.

Easy-picker

class App : Application() {
    override fun onCreate() {
        super.onCreate()
        EasyPicker.init(Config.defaultConfig(this))
      	// OR
        EasyPicker.init(
          Config.Builder()
          .copyDir(File(cacheDir, "easy_picker"))
          .noMedia()
          .outputFactory { cxt ->
                          EasyFP.withDefault(cxt)
                            .cacheDir()
                            .mkdirs("easy_picker")
                            .name(UUID.randomUUID().toString())
                            .pair()
                         }
          .build()
    }
}
