CacheUtilsLibrary
This is a simple Android utils library to write any type of data into cache files and then read them later, using Gson to serialize and deserialize these data.

Gradle
compile 'com.lifeofcoding:cacheutilslibrary:1.0.1@aar' compile 'com.google.code.gson:gson:2.2.2' compile 'org.apache.commons:commons-lang3:3.1' compile 'commons-io:commons-io:2.4'If you have errors like:
duplication file during packaging of APK ... Path in archive: META-INF/LICENSE.txt ... Please add such code in your android entry of your build.gradle file:
packagingOptions { exclude 'META-INF/DEPENDENCIES' exclude 'META-INF/NOTICE' exclude 'META-INF/LICENSE' exclude 'META-INF/LICENSE.txt' exclude 'META-INF/NOTICE.txt' exclude 'META-INF/ASL2.0' exclude 'META-INF/MANIFEST.MF' }Configuration
You need to configure CacheUtilsLibrary in your Application class.
public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); // configure CacheUtilsLibrary CacheUtils.configureCache(this); } }Don't forget to declare the MyApplication class in your AndroidManifest.xml file.
Usage
All sample code can be found in the MainActivity file.
Cache String File
// write CacheUtils.writeFile(CACHE_FILE_STRING, CACHE_FILE_CONTENT_STRING); // read String fileContent = CacheUtils.readFile(CACHE_FILE_STRING); Cache Map<String, T> File
// write CacheUtils.writeDataMapFile(CACHE_FILE_MAP, getCacheFileContentMap()); // read Map<String, Object> mapData = CacheUtils.readDataMapFile(CACHE_FILE_MAP); // get mapData private static Map<String, Object> getCacheFileContentMap() { Map<String, Object> mapData = new HashMap<>(); mapData.put("firstItem", "item0"); mapData.put("secondItem", 1); mapData.put("thirdItem", false); return mapData; } Cache List<Map<String, T> File
// write CacheUtils.writeDataMapsFile(CACHE_FILE_LIST_MAP, getCacheFileContentListMap()); // read List<Map<String, Object>> listMapData = CacheUtils.readDataMapsFile(CACHE_FILE_LIST_MAP); // get listMapData private static List<Map<String, Object>> getCacheFileContentListMap() { List<Map<String, Object>> listMapData = new ArrayList<Map<String, Object>>(); for (int i = 0; i < 4; i++) { Map<String, Object> item = new HashMap<>(); item.put("firstItemAt" + i, "item0At" + i); item.put("secondItemAt" + i, 1 + i); item.put("thirdItemAt" + i, i % 2 == 0); listMapData.add(item); } return listMapData; } Cache Object File
// write CacheUtils.writeObjectFile(CACHE_FILE_OBJECT, MyClass.SAMPLE_MYCLASS_1); // read MyClass myClassSample = CacheUtils.readObjectFile(CACHE_FILE_OBJECT, new TypeToken<MyClass>(){}.getType());You can see MyClass and MyClass.SAMPLE_MYCLASS_1 here and here.
Cache List<Object> File
// write CacheUtils.writeObjectFile(CACHE_FILE_LIST_OBJECT, getCacheFileContentListObject()); // read List<MyClass> myClassList = CacheUtils.readObjectFile(CACHE_FILE_LIST_OBJECT, new TypeToken<List<MyClass>>(){}.getType()); // get List<MyClass> data private static List<MyClass> getCacheFileContentListObject() { List<MyClass> listObject = new ArrayList<>(); listObject.add(MyClass.SAMPLE_MYCLASS_1); listObject.add(MyClass.SAMPLE_MYCLASS_2); listObject.add(MyClass.SAMPLE_MYCLASS_3); return listObject; } License
