#### 依赖
将其添加到根build.gradle文件（而不是模块build.gradle文件）中：

```Xml
    allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }
```
然后，将库添加到模块中 build.gradle
```Xml
    dependencies {
        implementation 'com.gitee.gt50:GtUtils:Tag'
    }
```
## PermissionUtils
```Java
  new PermissionUtils.Builder(this)
        .permission(Manifest.permission.RECORD_AUDIO, Manifest.permission.CAMERA)
        .onGranted(() -> {
            Toast.makeText(this, "允许", Toast.LENGTH_LONG).show();
         })
         .onDenied(requestPermissions -> {
            Toast.makeText(this, requestPermissions + " : 拒绝", Toast.LENGTH_LONG).show();
         })
         .start();
```
#### 设置拒绝后的弹窗提示语  默认提示语：没有此权限，无法开启这个功能，请开启权限：摄像头
````Java
  PermissionUtils.permissionsHintHead = "没有此权限，无法开启这个功能，请开启权限：";
````

## DataCleanManager
##### 获取缓存大小
````Java
static String getTotalCacheSize(Context context) throws Exception;
````
##### 清除缓存
````Java
static void clearAllCache(Context context);
````

## MuchThreadDown
###### 线程的数量根据文件的大小自动分配，每个线程下载的数据量最多3M;
````Java
  new MuchThreadDown("http://img1.kuaimashi.com/69_1526641455014.mp4", "D:/video/").download(new OnDownloadListener() {
      @Override
      protected void onDownloadComplete(String name, String url, String filePath) {
          System.out.println("下载成功==" + "url:" + url);
      }

      @Override
      protected void onDownloadError(String url, Exception e) {
          System.out.println("下载失败==" + "url:" + url);
      }

      @Override
      protected void onDownloads(String url, int completed, int endIndex) {
          System.out.println("下载中==" + "url:" + url + ":（" + completed + "||" + endIndex + "）");
      }
  });
  //是否显示日志
  public MuchThreadDown isShowLog(boolean showLog);
  //是否单线程下载
  public MuchThreadDown isAlone(boolean alone);
  //是否覆盖下载
  public MuchThreadDown isCover(boolean cover);
````

## ComputeUtils
#### api详见源码

## ClassesReader  
#### 类读取器，可以获取所有的类，用于实现获取某一个接口或者类的所有子类，或者获取指定注解的类
```java
**
     * 获取应用程序下的所有Dex文件
     *
     * @param context 上下文
     * @return Set<DexFile>
     */
    public static Set<DexFile> applicationDexFile(Context context);  
    public static Set<DexFile> applicationDexFile(String packageCodePath);  
    public static List<Class<?>> reader(Context context);
    
    /**
     * 读取类路径下的所有类
     *
     * @param packageName     包名
     * @param packageCodePath 包路径
     * @return List<Class>
     */
    public static List<Class<?>> reader(String packageName, String packageCodePath);
    
    /**
     * 删除集合中没有指定注解的类
     *
     * @param classes
     * @param annotationType
     */
    public static List<Class<?>> deleteNotAnnotationClass(List<Class<?>> classes, Class<? extends Annotation> annotationType)

```

## RetrofitHelper
```java
    ApiService apiService = RetrofitHelper.create(this, ApiService.ApiUrl.BASE_URL, ApiService.class);
    RetrofitHelper.execute(apiService.userLogin(params), new DefaultObserver() {
        @Override
        public void onSuccess(Object response) {
            Toast.makeText(MainActivity.this, "请求成功", Toast.LENGTH_LONG).show();
        }
    });
```
