Android圆形头像拍照后“无法加载此图片”的问题解决方法（适配Android7.0）

feature: 点击选择拍照或者打开相册，选取图片进行裁剪最后设置为圆形头像。

problem: 拍好照片，点击裁剪，弹toast“无法加载此图片”。

solution: 在裁剪的class里加两行代码

intent.addflags(intent.flag_grant_read_uri_permission);

intent.addflags(intent.flag_grant_write_uri_permission);

主要代码如下：

   

 public static final string photo_image_file_name = "fileimg.jpg";
  public static final int camera_request_code = 100;
  public static final int image_request_code = 101;
  public static final int result_request_code = 102;
  private file tempfile = null;
  private uri imageuri;
  //跳转相机
  private void tocamera() {
    file outputimage = new file(getactivity().getexternalcachedir(),
        photo_image_file_name);
    try {
      if (outputimage.exists()) {
        outputimage.delete();
      }
      outputimage.createnewfile();
    } catch (ioexception e) {
      e.printstacktrace();
    }
    if (build.version.sdk_int >= 24) {
      imageuri = fileprovider.geturiforfile(getactivity(),
          "com.liushengjie.smartbutler.fileprovider", outputimage);
    } else {
      imageuri = uri.fromfile(outputimage);
    }
    //启动相机程序
    intent intent = new intent("android.media.action.image_capture");
    intent.putextra(mediastore.extra_output, imageuri);
    startactivityforresult(intent, camera_request_code);
    dialog.dismiss();
  }
  //跳转相册
  private void topicture() {
    intent intent = new intent(intent.action_pick);
    intent.settype("image/*");
    startactivityforresult(intent, image_request_code);
    dialog.dismiss();
  }
  @override
  public void onactivityresult(int requestcode, int resultcode, intent data) {
    if (resultcode != getactivity().result_canceled) {
      switch (requestcode) {
        //相机数据
        case camera_request_code:
          //tempfile = new file(environment.getexternalstoragedirectory(), photo_image_file_name);
          //startphotozoom(uri.fromfile(tempfile));
          startphotozoom(imageuri);
          break;
        //相册数据
        case image_request_code:
          startphotozoom(data.getdata());
          break;
        case result_request_code:
          //有可能点击舍弃
          if (data != null) {
            //拿到图片设置
            setimagetoview(data);
            //删除原来的图片
            if (tempfile != null) {
              tempfile.delete();
            }
          }
          break;
      }
    }
  }
  //裁剪
  private void startphotozoom(uri uri) {
    if (uri == null) {
      l.e("uri == null");
      return;
    }
    intent intent = new intent("com.android.camera.action.crop");
    intent.setdataandtype(uri, "image/*");
    intent.addflags(intent.flag_grant_read_uri_permission);
    intent.addflags(intent.flag_grant_write_uri_permission);
    //裁剪
    intent.putextra("crop", true);
    //宽高比例
    intent.putextra("aspectx", 1);
    intent.putextra("aspecty", 1);
    //图片质量
    intent.putextra("outputx", 320);
    intent.putextra("outputy", 320);
    //发送数据
    intent.putextra("return-data", true);
    startactivityforresult(intent, result_request_code);
  }
  //设置图片
  private void setimagetoview(intent data) {
    bundle bundle = data.getextras();
    if (bundle != null) {
      bitmap bitmap = bundle.getparcelable("data");
      profile_image.setimagebitmap(bitmap);
    }
  }
