Firebase storage 사용할 때 주의사항!!

1. 메니페스트에 저장소 권한 줄것!

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2. 파일의 경로는 휴대폰... 피씨로 착각하지 말것...

InputStream stream = null;
try {
    stream = new FileInputStream(new File("/storage/emulated/0/Pictures/KakaoTalk/1484276153455.JPEG"));
    uploadTask = imageReference.putStream(stream);
    uploadTask.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) {
            // taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
            Uri downloadUrl = taskSnapshot.getDownloadUrl();
        }
    });
} catch (FileNotFoundException e) {
    e.printStackTrace();
    Toast.makeText(this, "예외발생!!!", Toast.LENGTH_SHORT).show();
}

3. 파이어베이스 Storage에서 권한 설정 반드시 할 것.... 이거 안해서 ....ㅠㅠ

service firebase.storage {

  match /b/realtimedatabase-3d54a.appspot.com/o {

    match /{allPaths=**} {

      allow read, write;

    }

  }

}
