相機不返回到OnActivityResult

嗨，首先我知道這個問題已經被問了，但我堅持了一天多，我想用相機意圖拍照並保存在手機的ExternalStoragePublicDirectory，但在服用後圖片不會返回到OnActivityResult，也不會保存圖片。它不工作在Android 6和7：任何幫助將被諷刺！相機不返回到OnActivityResult

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);

集圖像烏里：

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; 

    }

文件提供路徑：

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

從Android版本大於6和等於6，你需要請求存儲和相機許可例如檢查此鏈接https://androidkennel.org/android-camera-access-tutorial/和https://developer.android.com/guide/topics/permissions/requesting.html

是的，我加那個也是。我請求'Manifest.permission.CAMERA'和'Manifest.permission.WRITE_EXTERNAL_STORAGE'，並從'onRequestPermissionsResult'啓動攝像機意圖，但我仍然有同樣的問題！ – saeed
