我从电话联系人列表中选择了联系人，并且还找到了特定人员的姓名和电话号码，但是当我想将联系人发送到像WhatsApp这样的Firebase时，我找不到上传联系人的实际路径。为什么我找到了上述例外...
使用代码选择联系人
private static final int REQUEST_READ_CONTACT = 234;
private static String[] PERMISSIONS_CONTACT = {
Manifest.permission.READ_CONTACTS
};
int permission = ActivityCompat.checkSelfPermission(ChatActivity.this, Manifest.permission.READ_CONTACTS);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(
ChatActivity.this,
PERMISSIONS_CONTACT,
REQUEST_READ_CONTACT
);
}else{
// we already have permission, lets go ahead and call camera intent
Intent contactIntent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
startActivityForResult(contactIntent, PHONE_NUMBER_REQUEST);
}
onActivityResult代码：
if (requestCode==4){
if (resultCode==RESULT_OK){
String phoneNo = null;
String name = null;
Uri uri2=data.getData();
String uri = String.valueOf(data.getData());
Cursor cursor = getContentResolver().query(uri2, null, null, null, null);
if (cursor.moveToFirst()) {
int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
int nameIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
phoneNo = cursor.getString(phoneIndex);
name = cursor.getString(nameIndex);
UploadContactsToFireBase(uri,name,phoneNo);
}else {
Toast.makeText(getApplicationContext(),"Something went wrong",Toast.LENGTH_SHORT).show();
}
cursor.close();
}
UploadContactsToFireBase：
void UploadContactsToFireBase(String contactsPath, final String contactName, final String phoneNumber ){
final Dialogs loader=new Dialogs(this);
loader.showDialog(Dialogs.DIALOG_CENTERED);
final String name = DateFormat.format("yyyy-MM-dd_hhmmss", new Date()).toString();
StorageReference filePath = documentsStorageReference.child(name+"_contacts");
final Uri uri = Uri.fromFile(new File(contactsPath));
UploadTask uploadTask = filePath.putFile(uri);
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(final UploadTask.TaskSnapshot taskSnapshot) {
loader.dismiss();
Uri downloadUrl = taskSnapshot.getDownloadUrl();
Toast.makeText(getApplicationContext(),"Download Url: "+downloadUrl,Toast.LENGTH_SHORT).show();
ContactModel contactModel = new ContactModel(downloadUrl.toString(),contactName,phoneNumber);
ChatMessage newMessage = new ChatMessage(null,mCurrentUserId,mRecipientId,
null,null,Calendar.getInstance().getTime().getTime()+"",null,null,null,contactModel);
messageChatDatabase.push().setValue(newMessage);
}
});
uploadTask.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.e(TAG,"onFailure sendFileFirebase "+e.getMessage());
}
});
}
