カメラがクラッシュし

Question

を失敗した私は写真を撮るとアプリが言うとき、私はカメラがクラッシュし、次の

@AfterPermissionGranted(RC_STORAGE_PERMS) 
private void launchCamera() { 
    Log.d(TAG, "launchCamera"); 

    // Check that we have permission to read images from external storage. 
    String perm = Manifest.permission.WRITE_EXTERNAL_STORAGE; 
    if (!EasyPermissions.hasPermissions(this, perm)) { 
     EasyPermissions.requestPermissions(this, getString(R.string.rationale_storage), 
       RC_STORAGE_PERMS, perm); 
     return; 
    } 


    // Choose file storage location, must be listed in res/xml/file_paths.xml 
    File dir = new File(Environment.getExternalStorageDirectory() + "/photos"); 
    File file = new File(dir, UUID.randomUUID().toString() + ".jpg"); 
    try { 
     // Create directory if it does not exist. 
     if (!dir.exists()) { 
      dir.mkdir(); 
     } 
     boolean created = file.createNewFile(); 
     Log.d(TAG, "file.createNewFile:" + file.getAbsolutePath() + ":" + created); 
    } catch (IOException e) { 
     Log.e(TAG, "file.createNewFile" + file.getAbsolutePath() + ":FAILED", e); 
    } 

    // Create content:// URI for file, required since Android N 
    // See: https://developer.android.com/reference/android/support/v4/content/FileProvider.html 
    mFileUri = FileProvider.getUriForFile(this, 
      "com.mordred.youlift.fileprovider", file); 



    //this is my own set of fixes to grant permission to uri, not sure its neceary though, seems like overkill 
    Context context = this; 
    Intent intent = new Intent(); 
    intent.setAction(Intent.ACTION_SEND); 
    List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); 
    for (ResolveInfo resolveInfo : resInfoList) { 
     String packageName = resolveInfo.activityInfo.packageName; 
     context.grantUriPermission(packageName, mFileUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION); 
    } 
    // Create and launch the intent 
    context.grantUriPermission(getPackageName(), mFileUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION); 
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    takePictureIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri); 

    //condition suggested by android developers 
    if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
     startActivityForResult(takePictureIntent, RC_TAKE_PICTURE); 
    } 
} 

を使用してfirebaseストレージに画像をアップロードしようとしています応じて「写真を撮る失敗しました」 onactivityresult（）関数内のif構造体に渡します。ここではそのコードがある

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     Log.d(TAG, "onActivityResult:" + requestCode + ":" + resultCode + ":" + data); 
     if (requestCode == RC_TAKE_PICTURE) { 
      if (resultCode == RESULT_OK) { 
       if (mFileUri != null) { 
        uploadFromUri(mFileUri); 
       } else { 
        Log.w(TAG, "File URI is null"); 
       } 
      } else { 
       Toast.makeText(this, "Taking picture failed.", Toast.LENGTH_SHORT).show(); 
      } 
     } 
    } 

私のスタックトレースは、あなたがACTION_IMAGE_CAPTUREを使用しているとして、あなたに何か良いをしていないされ、活動の上にループがACTION_SENDのためである、

Answer 1

ファーストです。

第2に、Intent.FLAG_GRANT_WRITE_URI_PERMISSIONからtakePictureIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);を追加します。

はまた、あなただけそれらのいずれかを実行する必要があることに注意してください：addFlags()またはgrantUriPermission()、OSのバージョンによって：

if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) { 
    i.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION); 
    } 
    else { 
    List<ResolveInfo> resInfoList= 
     getPackageManager() 
     .queryIntentActivities(i, PackageManager.MATCH_DEFAULT_ONLY); 

    for (ResolveInfo resolveInfo : resInfoList) { 
     String packageName = resolveInfo.activityInfo.packageName; 
     grantUriPermission(packageName, outputUri, 
     Intent.FLAG_GRANT_WRITE_URI_PERMISSION | 
      Intent.FLAG_GRANT_READ_URI_PERMISSION); 
    } 
    } 

（iがACTION_IMAGE_CAPTUREIntentです）そのコードが来る
