錯誤110同時運行make

Question

，我發現了以下錯誤：

frameworks/base/core/java/android/os/mypackage/MyServiceListenerClass.java:283: error 110: Parameter of unavailable type android.os.storage.VolumeInfo in android.os.mypackage.MyServiceListenerClass.myMethod()

我創建了一個新包了一些類和這些類使用VolumeInfo從storage包。

我找不到有關此錯誤的任何文檔。我做錯了什麼？

UPDATE：

• 發現，Error 110 = UNAVAILABLE_SYMBOL。

• 發現在doclava/Stubs.java本節：

  for (ParameterInfo p : m.parameters()) { 
      TypeInfo t = p.type(); 
      if (!t.isPrimitive()) { 
       hiddenClass = findHiddenClasses(t); 
       if (null != hiddenClass) { 
       if (hiddenClass.qualifiedName() == t.asClassInfo().qualifiedName()) { 
        // Parameter type is hidden 
        Errors.error(Errors.UNAVAILABLE_SYMBOL, m.position(), 
         "Parameter of unavailable type " + t.fullName() + " in " + cl.qualifiedName() 
         + "." + m.name() + "()"); 
       } else { 
        // Parameter type contains a generic parameter 
        Errors.error(Errors.HIDDEN_TYPE_PARAMETER, m.position(), 
         "Parameter uses type parameter of unavailable type " + t.fullName() + " in " 
         + cl.qualifiedName() + "." + m.name() + "()"); 
       } 
       } 
      } 
  }

因此，對於這個錯誤的原因是在VolumInfo的文檔部分的底部的@hide屬性：

/** 
* Information about a storage volume that may be mounted. A volume may be a 
* partition on a physical {@link DiskInfo}, an emulated volume above some other 
* storage medium, or a standalone container like an ASEC or OBB. 
* <p> 
* Volumes may be mounted with various flags: 
* <ul> 
* <li>{@link #MOUNT_FLAG_PRIMARY} means the volume provides primary external 
* storage, historically found at {@code /sdcard}. 
* <li>{@link #MOUNT_FLAG_VISIBLE} means the volume is visible to third-party 
* apps for direct filesystem access. The system should send out relevant 
* storage broadcasts and index any media on visible volumes. Visible volumes 
* are considered a more stable part of the device, which is why we take the 
* time to index them. In particular, transient volumes like USB OTG devices 
* <em>should not</em> be marked as visible; their contents should be surfaced 
* to apps through the Storage Access Framework. 
* </ul> 
* 
* @hide 
*/ 

刪除它可以解決問題。
