小米手机调用com.android.camera.action.CROP时剪裁图片不成功的原因

[SouthMa]

最近向做一个头像剪裁的功能，调用系统的gallery选择图片，用com.android.camera.action.CROP对URI剪裁便可以实现。
用联想的一部手机测试如下代码没问题

public void ChooseImage(View v) {
		Intent intent = new Intent(Intent.ACTION_GET_CONTENT);// ACTION_OPEN_DOCUMENT
		intent.addCategory(Intent.CATEGORY_OPENABLE);
		intent.setType("image/*");
		if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
			startActivityForResult(intent, SELECT_PIC_KITKAT);
		} else {
			startActivityForResult(intent, SELECT_PIC);
		}
	}

@Override
	public void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (RESULT_OK == resultCode) {
			switch (requestCode) {
			case SELECT_PIC_KITKAT:
				Uri selectedImage = data.getData();
				startPhotoZoom(selectedImage);
				break;
			case 3:
				if(data != null){  
	                setPicToView(data);  
	            }
				break;
			default:
				break;
			}
		}
	}

public void startPhotoZoom(Uri uri) {
		Intent intent = new Intent("com.android.camera.action.CROP");
		intent.setDataAndType(uri, "image/*");
		intent.putExtra("crop", "true");
		intent.putExtra("aspectX", 1);
		intent.putExtra("aspectY", 1);
		intent.putExtra("outputX", 150);
		intent.putExtra("outputY", 150);
		intent.putExtra("return-data", true);
		startActivityForResult(intent, 3);
	}

但是小米系统下提示加载图片失败，去看了下log提示如下：

猜测调用com.android.camera.action.CROP实际为com.miui.gallery:crop缺少权限。

已经解决了，4.4后gallery的最近和图片返回的content前缀的uri，需要将其转换为file:///前缀的绝对地址，然后再去调用com.android.camera.action.CROP，将该uri给setData，就不会有权限问题了。

同样的程序，在使用小米系统的手机上调用时，无法显示相应效果

遇到相同问题，miui裁剪图片后直接回到主界面，无法响应onActivityResult()。

楼主 剪裁是点击应用 meifany

http://blog.csdn.net/eclothy/article/details/42719217 这个方法 那还不如不掉用裁剪 应为它获取的是裁剪之前的图
