I'm having a problem with my application. The application is supposed to send a message using volume key buttons on the phone. The problem is that it keeps stopping and I do not know if it works. Here is the code, I also added some wake lock in order for my app to stay active even when phone is locked.
public class MainActivity extends Activity {
private final static int SEND_SMS_PERMISSION_REQUEST_CODE = 111;
private Button sendMessage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag");
wl.acquire();
setContentView(R.layout.activity_main);
sendMessage = findViewById(R.id.send_message);
final EditText phone = findViewById(R.id.phone_no);
final EditText message = findViewById(R.id.message);
sendMessage.setEnabled(false);
if (checkPermission(Manifest.permission.SEND_SMS)) {
sendMessage.setEnabled(true);
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.SEND_SMS}, SEND_SMS_PERMISSION_REQUEST_CODE);
}
sendMessage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String msg = message.getText().toString();
String phonenumber = phone.getText().toString();
if (!TextUtils.isEmpty(msg) && !TextUtils.isEmpty(phonenumber)) {
if (checkPermission(Manifest.permission.SEND_SMS)) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(String.valueOf(phone), null, msg, null, null);
} else {
Toast.makeText(MainActivity.this, "Permission denied", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(MainActivity.this, "Enter a message and a phone number", Toast.LENGTH_SHORT).show();
}
}
});
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)) {
sendMessage.setEnabled(true);
return true;
} else if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)) {
sendMessage.setEnabled(true);
return true;
} else
return super.onKeyDown(keyCode, event);
}
private boolean checkPermission(String permission) {
int checkPermission = ContextCompat.checkSelfPermission(this, permission);
return checkPermission == PackageManager.PERMISSION_GRANTED;
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case SEND_SMS_PERMISSION_REQUEST_CODE:
if (grantResults.length > 0 && (grantResults[0] == PackageManager.PERMISSION_GRANTED)) {
sendMessage.setEnabled(true);
}
break;
}
}
}
Right now your code is not sending any messages when you press the volume key nor when you release it. You need to add this to your code:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)) {
String msg = message.getText().toString();
String phonenumber = phone.getText().toString();
if (!TextUtils.isEmpty(msg) && !TextUtils.isEmpty(phonenumber)) {
if (checkPermission(Manifest.permission.SEND_SMS)) {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(String.valueOf(phone), null, msg, null, null);
} else {
Toast.makeText(MainActivity.this, "Permission denied", Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(MainActivity.this, "Enter a message and a phone number", Toast.LENGTH_SHORT).show();
}
...
}
Also, you're missing n opening bracket on the final else of your onKeyDown()

I want to send an SMS with location to the contact that the user has been saved. But I don't know how to do it. I am totally new to Android Studio, so I don´t know how to write my code that it will work the way I want it.
Please, can you help me to do that?
This is the code of sending SMS:
Button sendBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sendBtn = (Button) findViewById(R.id.btnSendSMS);
sendBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
sendSMSMessage();
}
});
}
protected void sendSMSMessage() {
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.SEND_SMS)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.SEND_SMS)) {
// fixme: show explanation
// before requesting the permission again
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
} else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}
} else {
sendSmsImpl();
}
}
#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) {
sendSmsImpl();
} else {
// fixme: explain that it can't send SMS without the permission
Toast.makeText(getApplicationContext(),
"SMS faild, please try again.", Toast.LENGTH_LONG).show();
return;
}
// !!! NOTE: you still need break inside switch/case
// even with curly braces
break;
}
}
}
private void sendSmsImpl() {
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("+212xxx", null, "Je suis en danger, voici ma localisation : https://www.google.com/maps/search/?api=1&query=<lat>,<lng>", null, null);
//todo: use sentIntent argument of sendTextMessage to detect success/error
Toast.makeText(getApplicationContext(),
"SMS sent.", Toast.LENGTH_LONG).show();
}
And this the code of saving contact:
private int id;
private String phoneNo;
private String name;
// constructor
public ContactModel(int id, String name, String phoneNo) {
this.id = id;
this.phoneNo = validate(phoneNo);
this.name = name;
}
// validate the phone number, and reformat is necessary
private String validate(String phone) {
// creating StringBuilder for both the cases
StringBuilder case1 = new StringBuilder("+212");
StringBuilder case2 = new StringBuilder("");
// check if the string already has a "+"
if (phone.charAt(0) != '+') {
for (int i = 0; i < phone.length(); i++) {
// remove any spaces or "-"
if (phone.charAt(i) != '-' && phone.charAt(i) != ' ') {
case1.append(phone.charAt(i));
}
}
return case1.toString();
} else {
for (int i = 0; i < phone.length(); i++) {
// remove any spaces or "-"
if (phone.charAt(i) != '-' || phone.charAt(i) != ' ') {
case2.append(phone.charAt(i));
}
}
return case2.toString();
}
}
public String getPhoneNo() {
return phoneNo;
}
public int getId() {
return id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
I am working on a project for school and trying to send SMS to the user phone. The message is sent twice instead of once. How do I fix that problem?
Here is my code:
private static final int MY_PERMISSIONS_REQUEST_SEND_SMS =1 ;
EditText textphone;
String message;
String phoneNo;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_r_e_g_i_s_t_e_r);
textphone=findViewById(R.id.phone);
c = findViewById(R.id.create1);
c.setOnClickListener(this);
c.setEnabled(false);
if(!checkPermission(Manifest.permission.SEND_SMS)){
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.SEND_SMS},
MY_PERMISSIONS_REQUEST_SEND_SMS);
}else{
c.setEnabled(true);
}
}
public void onClick(View v) {
if (v == c) {
sendmessage();}
now the method:
private void sendmessage() {
if(checkPermission(Manifest.permission.SEND_SMS))
{
message="Hello "+ username2.getText().toString()+",welcome to Chatime. Hope you enjoy from our app.";
phoneNo=textphone.getText().toString();
if(phoneNo.length()==0){
return;
}
SmsManager smsManager=SmsManager.getDefault();
smsManager.sendTextMessage(phoneNo,null,message,null,null);
Toast.makeText(getApplicationContext(), "Message Sent", Toast.LENGTH_SHORT).show();
}else {
Toast.makeText(getApplicationContext(), "Permission Denied", Toast.LENGTH_SHORT).show();
}
}
public boolean checkPermission(String permission){
int check=ContextCompat.checkSelfPermission(this,permission);
return (check==PackageManager.PERMISSION_GRANTED);
}
in my code the permission log will be display but the phone number is not visible in toast

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.
