mui---调用图像裁剪android

mui调用图像裁剪android：

var IMAGE_UNSPECIFIED = "image/*"; //相册显示的文件类型
var PHOTOZOOM = 2; // 获取完图片返回key
var PHOTOLAT = 1; // 剪裁完毕后返回key
var main = plus.android.runtimeMainActivity(); //h5+获取应用主Activity实例对象
var Intent = plus.android.importClass("android.content.Intent");
//导入java类intent对象  以下importClass都是使用安卓原生类
var MediaStore = plus.android.importClass("android.provider.MediaStore");
var File = plus.android.importClass("java.io.File");
var Uri = plus.android.importClass("android.net.Uri");
var intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);
intent.putExtra("scale", true);
intent.putExtra("scaleUpIfNeeded", true);
var outPutPath = plus.io.convertLocalFileSystemURL("_www/head.jpg");
main.startActivityForResult(intent, PHOTOZOOM);
// uploadImgPath
main.onActivityResult = (requestCode,resultCode,data)=>{
// main.onActivityResult = function(requestCode, resultCode, data) {
    if (PHOTOZOOM == requestCode) {         
        var file = new File(outPutPath);
        // 输出目录uri
        var outPutUri = Uri.fromFile(file);
        if (data == undefined) {
            return false;
        }
        plus.android.importClass(data);
        var uri = data.getData();
        var cropIntent = new Intent("com.android.camera.action.CROP"); //裁剪
        cropIntent.setDataAndType(uri, IMAGE_UNSPECIFIED);
        // 截图完毕后 输出目录
        cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outPutUri);
        cropIntent.putExtra("crop", "true");
        //aspectX aspectY 是宽高的比例
        cropIntent.putExtra("aspectX", 1);
        cropIntent.putExtra("aspectY", 1);
        // outputX outputY 是裁剪图片宽高
        cropIntent.putExtra("outputX", 70);
        cropIntent.putExtra("outputY", 70);
        cropIntent.putExtra("return-data", true);
        main.startActivityForResult(cropIntent, PHOTOLAT);
    } else if (requestCode == PHOTOLAT) {
        if (data == undefined) {
            return false;
        }
        var a = new File(outPutPath);
        if (!a.exists()) {
            console.log(outPutPath);
            mui.toast('裁剪错误');
            return false;
        }
        var base64Path = 
        this.uploadImgPath = outPutPath;
        console.log(outPutPath);
        alert(outPutPath);
        // img.src = outPutPath;
    };
};
