相机不返回 OnActivityResult

Question

嗨，首先我知道这个问题已经被问过了，但我坚持了不止一天我想用相机意图拍照并将其保存在手机的ExternalStoragePublicDirectory 上，但拍照后它没有'不返回OnActivityResult 也不保存图片。它在 android 6 和 7 中不起作用： 任何帮助都会得到帮助！

Uri imageUri = setImageUri();
Intent intent1 = new 
Intent(MediaStore.ACTION_IMAGE_CAPTURE);

intent1.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, imageUri);

intent1.setFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

List<ResolveInfo> resInfoList = 
MedicalActivity.this.getPackageManager().queryIntentActivities(intent1, 
PackageManager.MATCH_DEFAULT_ONLY);

for (ResolveInfo resolveInfo : resInfoList) {
String packageName =resolveInfo.activityInfo.packageName; 


MainActivity.this.grantUriPermission(packageName, imageUri, 
Intent.FLAG_GRANT_WRITE_URI_PERMISSION | 
Intent.FLAG_GRANT_READ_URI_PERMISSION);
}

startActivityForResult(intent1, CAPTURE_IMAGE);

设置图片Uri：

if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.KITKAT) {

        File mediaStorageDir = new File(
                Environment
                        .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
                "myappimages");
if (!mediaStorageDir.exists()) {mediaStorageDir.mkdir();}
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
                Locale.getDefault()).format(new Date());
        File file;
        file = new File(mediaStorageDir.getPath() + File.separator
                + "IMG_" + timeStamp + ".jpg");


        Uri imgUri = FileProvider.getUriForFile(MedicalActivity.this,
                BuildConfig.APPLICATION_ID + ".provider",
                file);

        return imgUri;

    }

文件提供者路径：

<external-path name="myapp_images_path" path="Pictures/myappimages"/>

android 版本大于 6 等于 6 需要申请存储和摄像头权限 例如检查这个链接https://androidkennel.org/android-camera-access-tutorial/和https://developer.android.com/guide/topics/permissions/requesting.html
