这是我基于Android s3文档的内容，我试图从照片库中选择图片或从手机拍照并将其上传到S3存储桶并将其恢复到应用程序界面。但是时间我运行程序我的应用程序崩溃了。我叫了

//getting access to the photo gallery
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && data != null) {
        Uri selectedImage = data.getData();
        uploadImage.setImageURI(selectedImage);
    }
    Toast.makeText(this, "Test", Toast.LENGTH_LONG).show();

}

加入

  uploadImageToAWS(v)

任何示例或小帮助将不胜感激。谢谢！

尝试检查Android Manifests文件中是否具有使用权限Internet。如果这不起作用，请尝试查看是否可以将应用程序外部的图像（例如，通过命令行）上传到您的存储桶。也许有一些你没有正确设置的安全设置。确保您可以ping服务器并正确设置安全设置。
