android 7.0 相机，拍照 调裁切提示 “无法加载此图片” 解决方案

 

调起相机拍照之后，在调起裁切之前  加上 这两句代码，，

Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
//需要加上这两句话 ： uri 权限
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

intent.putExtra("crop", "true");
intent.putExtra("aspectX", 400);
intent.putExtra("aspectY", 400);
intent.putExtra("output", Uri.fromFile(loadingFile));// 输出到文件
intent.putExtra("outputFormat", "PNG");// 返回格式
intent.putExtra("noFaceDetection", true); // 去除面部检测
intent.putExtra("return-data", false); // 不要通过Intent传递截获的图片
startActivityForResult(intent, AVATAR_ZOOM);
