准备工作：在libs下添加 alicloud--apigateway-sdk-1.0.1.jar,commons-codec-1.10-1.jar

          在build.gradle添加  compile'com.squareup.okhttp3:okhttp:3.4.1'

在onCreate,或者afterViews初始化API网关

private void initGatewaySdk() {    // 初始化API网关    ApiGatewayClient.init(getApplicationContext(), false);}

调用拍照功能

private void getPhotoCard(){    final String status = Environment.getExternalStorageState();    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {        requestPermissions(new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, CAMERA_REQUEST_CODE);    }    if (status.equals(Environment.MEDIA_MOUNTED)) {        defaultPhotoAddress = PHOTO_DIR + "/" + getPhotoName();        PreferenceUtils.modifyStringValueInPreferences(CardActivity.this, Preferences.IMAGE_3, defaultPhotoAddress);        imageUri = Uri.fromFile(new File(defaultPhotoAddress));        Intent intentPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//action is capture        intentPhoto.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);        startActivityForResult(intentPhoto, CAMERA_REQUEST_CODE);    } else {        Toast.makeText(CardActivity.this, "没有sd卡", Toast.LENGTH_SHORT).show();    }} 可以对照片进行裁剪

private void cropImageUri(Uri desUri, int outputX, int outputY, int requestCode){    Intent intent = new Intent("com.android.camera.action.CROP");    intent.setDataAndType(desUri, "image/*");    intent.putExtra("crop", "true");    intent.putExtra("aspectX", 5);    intent.putExtra("aspectY", 3);    intent.putExtra("outputX", outputX);    intent.putExtra("outputY", outputY);    intent.putExtra("scale", true);    intent.putExtra(MediaStore.EXTRA_OUTPUT, desUri);    intent.putExtra("return-data", false);    intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());    intent.putExtra("noFaceDetection", true);    startActivityForResult(intent, requestCode);} 用base64上传照片
