Hi, I'm Seyoung.
I want to use your code in my commercial app.
But I can'f find any terms and conditions for use, reproduction, and distribution.
I wonder if I can use the code for commercial distribution or not.
Please let me know how I can use the code for commercial distribution.
Thanks.

Not a document Error
Hi,
Thanks for the util. Helped me a lot. But I encounter one issue when i try to get the URI from camera intent.
Phone is Sony Experia Z, android 4.4, the camera stores the images in an external SD Card
The URI returned will be something like content://media/external/images/media/174394
Because it is 4.4, it will go to getRealPathFromURI_API19() method, but it will fail at this line
String wholeID = DocumentsContract.getDocumentId(uri);
returning a Not a document error
So what I did (which is working for me) was
public static String getRealPathFromURI_API19(Context context, Uri uri){
String filePath = "";
if (String.valueOf(uri).contains("documents")) {
String wholeID = DocumentsContract.getDocumentId(uri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = { MediaStore.Images.Media.DATA };
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{ id }, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
} else {
filePath = getRealPathFromURI_API11to18(context, uri);
}
return filePath;
}
But, do you think it is a good idea? or there is a better condition to check rather than checking if uri contains the word 'documents'?

Android Studio error: "Method getText() must be called from the UI Thread, currently inferred thread is worker
Hi. I'm doing a Android Studio Project, with some AsyncTasks, and at some point it gives me the error at the Title. I know that i really can't use method getText it in doInBackground, but i've tried to do the recommended changes from another questions, to the code and nothing seems to work. This is my code:
`public class LoginActivity extends AppCompatActivity {
Button btSignIn;
Button btSignUp;
EditText edtEmail;
EditText edtPassword;
String CHANNEL_ID = "personal_notification";
int NOTIFICATION_ID = 001;
UserDatabase database;
UserDao userDao;
User userTemp = new User();
SharedPreferences emailSharedPref;
ProgressDialog progressDialog, progressDialogDownload;
@Override
protected void onStart() {
super.onStart();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Log.d("MYTAG", "inicio ");
progressDialog = new ProgressDialog(this);
progressDialog.setCancelable(false);
progressDialog.setMessage("A verificar utilizador...");
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressDialog.setProgress(0);
database = Room.databaseBuilder(getApplicationContext(), UserDatabase.class, "mi-database.db").build();
userDao = database.getUserDao();
btSignIn = findViewById(R.id.btSignIn);
btSignUp = findViewById(R.id.btSignUp);
edtEmail = findViewById(R.id.email);
edtPassword = findViewById(R.id.password);
btSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(LoginActivity.this, SignUpActivity.class));
}
});
btSignIn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LoadAsyncTaskLogin loadAsyncTaskLogin = new LoadAsyncTaskLogin();
loadAsyncTaskLogin.execute(userTemp);
}
});
}
public class LoadAsyncTaskLogin extends AsyncTask<User, Void, User> {
@Override
protected User doInBackground(User... users) {
String email = edtEmail.getText().toString();
String password = edtPassword.getText().toString();
User user2 = new User();
user2 = database.getUserDao().getUser(email,password);
return user2;
}
@Override
protected void onPostExecute(User user2){
Intent intentToWhatToChoose = new Intent(LoginActivity.this,WhatToChoose.class);
if(user2 != null){
if(user2.password.equals(edtPassword.getText().toString())){
emailSharedPref = getApplicationContext().getSharedPreferences("email",0);
SharedPreferences.Editor editor = emailSharedPref.edit();
editor.putString("User Successfully Logged In",user2.email);
editor.commit();
startActivity(intentToWhatToChoose);
Toast.makeText(LoginActivity.this, "Welcome to Our App", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(LoginActivity.this, "Incorrect Credentials", Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(LoginActivity.this, "Incorrect Credentials", Toast.LENGTH_LONG).show();
}
}
}`
The error is on "doInBackground". What changes do i have to do?
