问题描述
我正在尝试使用改造将图片从图库或相机上传到服务器。
我的应用程序在 android 10 之前运行良好，我选择了使用范围存储，
val_ds = tf.keras.preprocessing.image_dataset_from_directory(
data_dir,validation_split=0.2,subset="validation",seed=121,image_size=(img_height,img_width),batch_size=batch_size)
但是在 android 11 中它被删除了所以我应该做些什么来修复范围存储的错误
android:requestLegacyExternalStorage="true"
显示对话框以选择厨房或相机

打开图库

拍照

关于活动结果

intent.putExtra("return-data",true);
startActivityForResult(intent,REQUEST_CODE_TAKE_PICTURE);
} catch (ActivityNotFoundException e) {
Log.d("","cannot take picture",e);
}
}
获取路径
@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == REQUEST_CODE_galLERY && resultCode == RESULT_OK) {
try {
final Uri imageUri = data.getData();
