Problem with send message using SmsManager

I'm a beginner in Android. I tried to do application to send SMS. The applications stops working when I try to send a message on my phone. A message appears in the emulator: "Send sent". I don't understand what the problem is.
Application code:
public class MainActivity extends AppCompatActivity {
private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;
Button sendBtn;
EditText txtphoneNo;
EditText txtMessage;
String phoneNo;
String message;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sendBtn = (Button) findViewById(R.id.btnSendSMS);
txtphoneNo = (EditText) findViewById(R.id.editText);
txtMessage = (EditText) findViewById(R.id.editText2);
sendBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendSMSMessage();
}
});
}
protected void sendSMSMessage() {
phoneNo = "+48" + txtphoneNo.getText().toString();
message = txtMessage.getText().toString();
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode,String permissions[], int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST_SEND_SMS: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo, null, message, null, null);
Toast.makeText(getApplicationContext(), "SMS sent.",
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
}
}
}
}
In AndroidManifest.xml I wrote:
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<uses-permission android:name="android.permission.READ_SMS"/>
Thank you in advance

How to get the image name when user upload the image from gallery and display them in textView?

I'm trying to retrieve the actual image name of the image selected by user in gallery(Ex. IMG_2020).
I tried using getAbsolutePath() and getName() but these 2 methods display something like "image$3A75" instead of the actual image file name.
Other than that, I also tried using some cursor method which I don't know really how it works, but it still doesn't work or maybe it's because I do not know how to use it.
Any help please?
This is my onActivityResult() method
fileName is the textView I want to place my imageName
bitMap object is not used yet because I'm following a tutorial online and I'm halfway copying, I think it will be used later in the tutorial
public class createCharity extends AppCompatActivity {
private static final int PICK_IMAGE_REQUEST = 1;
Button uploadButton;
Button createCharityButton;
TextView charityTitle;

private StorageReference mStorageRef;
private DatabaseReference mDatabaseRef;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), charityImage);

System.out.println("Image name: " + file.getName());
fileName.setText(file.getName());
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

Something like:
String projection [] = {
MediaStore.Images.Media.DATA
, MediaStore.Images.Media.DISPLAY_NAME
, MediaStore.Images.Media.SIZE};
Cursor cursor = getContentResolver().query(data.getData(), projection, null, null, null);

return;
}
cursor.moveToFirst();
String data = cursor.getString(0);
String displayName = cursor.getString(1);
String size = cursor.getString(2);
Toast.makeText(context, "getContentResolver().openInputStream() ok\n\n" + path
+ "\n\nDISPLAY_NAME: " + displayName
+ "\nDATA: " + data
+ "\nSIZE: " + size
, Toast.LENGTH_LONG).show();
cursor.close();
DATA not available on Android Q+.

Text message not being sent to a list of numbers but is sent when just one number is specified

I am trying to build an application where the user can send his/her location to the stored phone numbers in a sqlitedatabase. I tested the application where the user can send the location as a text message to just one phone number and it worked but now when I try to create a list of numbers and pass it as a parameter in sendTextMessage method of smsManager the location as a text message is not sent. I have tried out the given code below so far,
Code
public class Gps4Activity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener {
private static final String LOG_TAG = "PlacesAPIActivity";
private static final int GOOGLE_API_CLIENT_ID = 0;
private GoogleApiClient mGoogleApiClient;
private static final int PERMISSION_REQUEST_CODE = 100;
private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =0 ;
private TextView display;
private Button location_button,contacts_button;
//String number="xxxxxxxxxx";
ArrayList<String> numbers;
SQLiteDatabase db;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gps4);
numbers=new ArrayList<>();
db = new UserDatabase(this).getReadableDatabase();
location_button=(Button)findViewById(R.id.show_button);
contacts_button=(Button)findViewById(R.id.view_button);
display=(TextView)findViewById(R.id.location_textview);
mGoogleApiClient = new GoogleApiClient.Builder(Gps4Activity.this)
.addApi(Places.PLACE_DETECTION_API)
.enableAutoManage(this, GOOGLE_API_CLIENT_ID, this)
.build();
location_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (mGoogleApiClient.isConnected()) {
if (ActivityCompat.checkSelfPermission(Gps4Activity.this,
android.Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(Gps4Activity.this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
PERMISSION_REQUEST_CODE);
ActivityCompat.requestPermissions(Gps4Activity.this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
}
callPlaceDetectionApi();
}
});
contacts_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent(Gps4Activity.this,DetailsActivity.class);
startActivity(intent);
}
});
}
public ArrayList<String> getContacts(){
Cursor cursor=db.rawQuery("SELECT * FROM "+UserDatabase.TABLE_NAME,null);
while (cursor.moveToNext()){
String contact=cursor.getString(cursor.getColumnIndex(UserDatabase.NUMBER));
numbers.add(contact);
}
return numbers;
}
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Log.e(LOG_TAG, "Google Places API connection failed with error code: "
+ connectionResult.getErrorCode());
Toast.makeText(this,
"Google Places API connection failed with error code:" +
connectionResult.getErrorCode(),
Toast.LENGTH_LONG).show();
}
#Override
public void onRequestPermissionsResult(int requestCode,

switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
callPlaceDetectionApi();
} else {
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
break;
}
}
private void callPlaceDetectionApi() throws SecurityException {
PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
#Override
public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
Log.i(LOG_TAG, String.format("Place '%s' with " +
"likelihood: %g",
placeLikelihood.getPlace().getName(),
placeLikelihood.getLikelihood()));
display.setText(placeLikelihood.getPlace().getAddress().toString());
messageSending(placeLikelihood.getPlace().getAddress().toString());
break;
}
likelyPlaces.release();
}
});
}
public void messageSending(String message){
SmsManager smsManager = SmsManager.getDefault();
// smsManager.sendTextMessage(number, null, message, null, null);
getContacts();
smsManager.sendTextMessage(String.valueOf(numbers),null,message,null,null);
Toast.makeText(getApplicationContext(), "SMS sent."+String.valueOf(numbers),
Toast.LENGTH_LONG).show();
}
}
The commented lines are the ones when I tried to test the application with just one phone number. Also, suppose initially there is just one phone number in sqlitedatabase , as many times I click the location_button that many times the arraylist grows it's size. For example , initially if the arraylist has elements [xxxxxx] next time I click the location_button the arraylist will now have [xxxxxx,xxxxxx].
Can anyone help me solving this issue?

Since the sendTextMessage() method only can take one number at a time, you need to execute this method for each number in the list.
That being said you should 'loop' through that List. Like this:
for (String number : numbers) {
smsManager.sendTextMessage(numbers, null, message, null, null);
}
What it basically is saying is:
"Allright, let's take number one, sendTextMessage to number one, and I will keep doing this until I am done."

ActivityCompat can't find .checkSelfPermission in eclipse

I have create program which can send message. when I use Activity.checkSelfPermission, it show the error like "The method checkSelfPermission(MainActivity, String) is undefined for the type ActivityCompat". I have import android.support.v4.app.ActivityCompat already. My target API 23 and compile with API 23 also. How to solve it?
Below is the real code
public class MainActivity extends Activity {
public static final int MY_PERMISSION_SEND_SMS = 10;
public EditText edSMS, edPhone;
public Button btnSent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edSMS = (EditText)findViewById(R.id.editText1);
edPhone = (EditText)findViewById(R.id.editText2);
btnSent = (Button)findViewById(R.id.button1);
onCheckPermission();
}
private void onCheckPermission() {
if(ActivityCompat.checkSelfPermission(this,Manifest.permission.SEND_SMS)!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermission(this, new String[]{Manifest.permission.SEND_SMS}, MY_PERMISSION_SEND_SMS);
}
else {
sentMessage();
}
}
private void sentMessage() {
btnSent.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String phoneNumber = edPhone.getText().toString();
String SMS = edSMS.getText().toString();
if(((phoneNumber.length() == 10) || (phoneNumber.length()==9)) && phoneNumber.length()>0){
SmsManager smsText = SmsManager.getDefault();
smsText.sendTextMessage(phoneNumber, null, SMS, null, null);
Toast.makeText(MainActivity.this, "SMS was sent successful", Toast.LENGTH_LONG).show();
edPhone.setText("");
edSMS.setText("");
} else {
Toast.makeText(MainActivity.this, "Please check your " + "phone number again",Toast.LENGTH_LONG).show();
}
}
});
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults){
switch (requestCode){
case MY_PERMISSION_SEND_SMS:
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
Toast.makeText(this, "Read Contacts permission granted", Toast.LENGTH_SHORT).show();
sentMessage();
}else{
Toast.makeText(this, "Read Contacts permission denied", Toast.LENGTH_SHORT).show();
if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.SEND_SMS)){
new AlertDialog.Builder(this).
setTitle("Request Permission SMS").
setMessage(" You must set permission to access this application").show();
}
}
break;
}
}

To solve the method ActivityCompat.checkSelfPermission() not found in Eclipse you can simply add android-support-compat.jar as taken from https://github.com/dandar3/android-support-compat/tree/28.0.0 to the libs folder of your Eclipse project and compile again.

just use support.v7 (import android.support.v7.app.AppCompatActivity;),this is well be rolved
by the way?why do you still use eclipse now?just use Android studio,it's better so much.

Android AutoCompleteTextView with Email Not Populating

I'm trying to implementAutoCompleteTextView to populate the users email in a log-in activity for a better UX.
To comply with Google's specification to read contacts, this app asks permission from the user at run time using checkSelfPermission() method and that much I do know is working. However, when a user types in their user email, a drop-down list should show after at least two characters are inputted and this isn't happening.
Expected output:
Below is my implementation (attempt). Any feedback with code (correction) example will be greatly appreciated.

Replace your onCreateLoader() method code with below code.
public Loader<Cursor> onCreateLoader(int i, Bundle bundle) {
return new CursorLoader(this,
// Retrieve data rows for the device user's 'profile' contact.
ContactsContract.Data.CONTENT_URI, ProfileQuery.PROJECTION,
// Select only email addresses.
ContactsContract.Contacts.Data.MIMETYPE +
" = ?", new String[]{ContactsContract.CommonDataKinds.Email
.CONTENT_ITEM_TYPE},
// Show primary email addresses first. Note that there won't be
// a primary email address if the user hasn't specified one.
ContactsContract.Contacts.Data.IS_PRIMARY + " DESC");
}

You can do this
make your adapter as global variable and add textwatcher for input email ,and set your adapter only when text size reaches 2
inputEmail.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if (s.length() < 2) {
inputEmail.setAdapter(null)
}
else if(s.length()==2){
//this is to make sure adapter not getting set every time if length is greater than 2
inputEmail.setAdapter(adapter)
}
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void afterTextChanged(Editable s) {
}
});
change the condition as you prefer.Hope this helps

You can achieve this as follows:
First create a custom ArrayAdapter instead of
ArrayAdapter<String> adapter =
new ArrayAdapter<>(LoginActivity.this,
android.R.layout.simple_dropdown_item_1line, emailAddressCollection);
inputEmail.setAdapter(adapter);
Let's say we call it AutoCompleteAdapter and let it implement Filterable interface
public class AutoCompleteAdapter extends ArrayAdapter<String> implements Filterable {
Override the getFilter() and put the char length check to 2 chars for email.
