主要功能:清除内、外缓存,清除数据库,清除Sharepreference,清除files和清除自定义目录
public class DataCleanManager { //清除本应用内部缓存(/data/data/com.xxx.xxx/cache) public static void cleanInternalCache(Context context) { deleteFilesByDirectory(context.getCacheDir()); } //清除本应用所有数据库 public static void cleanDatabases(Context context) { deleteFilesByDirectory(new File("/data/data/" + context.getPackageName() + "/databases")); } //清除Sharepreference(/data/data/com.xxx.xxx/shared_prefs) public static void cleanSharedPreferenced(Context context){ deleteFilesByDirectory(new File("/data/data/" +context.getPackageName() +"/shared_prefs")); } //按名字清除本应用数据 public static void cleanDatabaseByName(Context context,String dbName){ context.deleteDatabase(dbName); } //清除/data/data/com.xxx.xxx.files下的内容 public static void cleanFiles(Context context){ deleteFilesByDirectory(context.getFilesDir()); } //清除外部cache下的内容(/mnt/sdcard/android/data/com.xxx.xxx/cache) public static void cleanExterbalCache(Context context){ if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){ deleteFilesByDirectory(context.getExternalCacheDir()); } } //清除自定义路径下的文件,使用需小心。并且只支持目录下的文件删除 public static void cleanCustomCache(String filePath){ deleteFilesByDirectory(new File(filePath)); } //清除本应用所有数据 public static void cleanApplicationData(Context context ,String... filepath){ cleanInternalCache(context); cleanExterbalCache(context); cleanDatabases(context); cleanSharedPreferenced(context); cleanFiles(context); for (String filePath : filepath){ cleanCustomCache(filePath); } } //删除方法,这里只会删除某个文件夹下的文件,如果传入的directory是个文件,将不做处理 private static void deleteFilesByDirectory(File directory) { if (directory != null && directory.exists() && directory.isDirectory()) { for (File item : directory.listFiles()) { item.delete(); } } } }
