Question

我的应用需要将图片上传到firebase存储并将其显示在recyclerView中。我的前两张图片在列表中显示得很好。但是，当我尝试上传第三张图片时，应用程序崩溃，也无法将图像存储在firebase上。每个图像大小从500KB到700KB不等。我也在我的清单中使用了android：largeHeap =“true”。怎么办？

//这是代码：

{ //Array at 0th index
            date = "16 December 2016";
            day = Friday;
            doctorName = "<null>";
            localTime = "07:30 AM";
            symptoms = q;
            today = Yes;
        },
                { //Array at 1st index
            date = "16 December 2016";
            day = Friday;
            doctorName = "<null>";
            localTime = "07:30 AM";
            symptoms = g;
            today = Yes;
        }
}

//发布后发生的事情是SUBMITED。

NSArray *allKeys;
        for (int i=0; i<[tempDict count]; i++) {
           allKeys = [[[tempDict valueForKey:@"upcomingConsultations"] objectAtIndex:i] allKeys];



            NSString *targetKey = nil;
            // NSArray *allKeys = [[tempDict valueForKeyPath:@"pastConsultations"] allKeys];
            for (int j = 0; j < [allKeys count]; ++j) {
                NSString *key = [allKeys objectAtIndex:i];
                NSString *obj = [[[tempDict valueForKey:@"upcomingConsultations"] objectAtIndex:i] objectForKey:key];
                if ([obj rangeOfString:searchText].location != NSNotFound) { // searchedString is what you're looking for
                    targetKey = key;
                    NSLog(@"found match");
                    break;
                }
            }
        }

尝试以下代码，我使用此代码将图片上传到firebase存储空间，如果您发现任何问题或有任何疑问，请告诉我

见下图，您可以看到图片已成功上传

1 - 在您的Java文件中，输入这些代码

private SimpleDraweeView imgProfile;
private FirebaseStorage storage;
private Uri file, resultUri;
private StorageMetadata metadata;
private UploadTask uploadTask;
private StorageReference storageRef;
private final String MY_BUCKET_PATH = "YOUR BUCKET PATH OF YOUR STORAGE";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_profile);

    storage = FirebaseStorage.getInstance();
    storageRef = storage.getReferenceFromUrl(MY_BUCKET_PATH);
}

2 - 在onActivityResult中将图片的Uri上传到firebase存储后，还要确保获得正确的图像Uri

private void UploadImage() {

    file = Uri.fromFile(new File(resultUri.getPath()));

    // Create the file metadata
    metadata = new StorageMetadata.Builder().setContentType("image/jpg").build();

    // Upload file and metadata to the path 'images/mountains.jpg'
    uploadTask = storageRef.child("images/" + file.getLastPathSegment()).putFile(file, metadata);

    // Listen for state changes, errors, and completion of the upload.
    uploadTask.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
            double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();
            showUploadProgress(progress);
            System.out.println("Upload is " + progress + "% done");
        }
    }).addOnPausedListener(new OnPausedListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onPaused(UploadTask.TaskSnapshot taskSnapshot) {
            System.out.println("Upload is paused");
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception exception) {
            // Handle unsuccessful uploads
        }
    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Log.e("Uploading image==", "onSuccess");
            // Handle successful uploads on complete
            Uri downloadUrl = taskSnapshot.getMetadata().getDownloadUrl();
            imgProfile.setImageURI(Uri.parse(downloadUrl.toString())); // Here image will be reflected after uploading
            mDialog.dismiss();
            Log.e("DownloadUrl getPath==>>", taskSnapshot.getDownloadUrl().getPath());
            Log.e("Metadata getPath==>>", taskSnapshot.getMetadata().getPath());  // this line will give you path to download Image from Firebase storage omitting child storage reference
            Log.e("Metadata dwndUrl getpath", taskSnapshot.getMetadata().getDownloadUrl().getPath());
            Log.e("storageRef path==>>", taskSnapshot.getMetadata().getReference().getPath());
            mSessionManager.storeStringValues("profile_photo", downloadUrl.toString());
            mSessionManager.storeStringValues("profile_photo_path", taskSnapshot.getMetadata().getPath());
        }
    });
}
