I have a broadcast receiver from which am calling intentservice.I want to send the data received in the intentservice to a activity.String s=extras.getString("Notice").I want to send this received string to a new activity
#Override
protected void onHandleIntent(Intent arg0) {
Intent dialogIntent = new Intent(getBaseContext(), myActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
dialogIntent.putExtra("value", extras.getString("Notice"));
getApplication().startActivity(dialogIntent);
}
public class YourIntentService extends IntentService {
#Override
protected void onHandleIntent(Intent arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(this, YourNewActivity.class);
intent.putExtra("YourStringKey", "yourString");
startActivity(intent);
}
public YourIntentService() {
super("YourIntentService");
}
}
Try this. Sorry for misunderstanding.
public class MyIntentService extends IntentService {
public MyIntentService() {
super(" MyIntentService");
}
#Override
protected void onHandleIntent(Intent arg0) {
String s=arg0.getExtras.getString("Notice")
Intent i = new Intent(this, yourActivity.class);
i.putExtra("Notice",s);
getApplication().startActivity(i);
}
}

public class one extends Activity{

super.onCreate(savedInstanceState);
Toast.makeText(getApplicationContext(),"lastpage",Toast.LENGTH_SHORT).show();
sendSms();
}
public void sendSms() {
Intent intent=getIntent();
String SMS=intent.getStringExtra("Message");
Intent intent1=getIntent();
String Contact=intent1.getStringExtra("Number");

public class AlarmReciever extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent intent1 = new Intent(context,one.class);
Toast.makeText(context, "Alarm is scheduled", Toast.LENGTH_LONG).show();
}
}
In this the Intent is not landing to one.java activity. And If possible please help if can write the sendSms method in Alarm Receiver.java activity
In your AlarmReceiver you never actually start the one activity. You also never add the extras you intend to pull out of it.
Try this:
Intent intent1 = new Intent(context,one.class);
intent1.putExtra("Message", "foo");
intent1.putExtra("Number", 123456789);
startActivity(intent1 );
You need to add startActivity(intent1); in the onReceive method
In your AlarmReciever, you missed out to start the called intent. It's an simple issue. Below i have given the corrected code
public class AlarmReciever extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent intent1 = new Intent(context,one.class);
startActivity(intent1);
Toast.makeText(context, "Alarm is scheduled", Toast.LENGTH_LONG).show();
}
}
On button click I am opening activity(ActionListActivity) and sending intent to IntentService (later this service sends broadCast intent to ActionListActivity). But I am usually receiving only the first intent after launch. Is it real that intent is sent before the receiver is registred?
I want to get data providet by the intentService, and update my UI using it.
Scheme Activity->IntentService->BroadCastReceiver inside ActionListActivity
Activity:
private void selectDrawerItem(MenuItem menuItem)
{
switch (menuItem.getItemId()) {
case R.id.actions:{
Intent myIntent = new Intent(this, ActionListActivity.class);
this.startActivity(myIntent);
ProgressDialog progressDialog = new ProgressDialog(this);
progressDialog.show();
Intent dataIntent = new Intent(this, DatabaseWorkIntentService.class);
dataIntent.putExtra(Utils.INTENT_SERVICE_INVOKE, Utils.READ_ACTIONS_DATA);
startService(dataIntent);
progressDialog.dismiss();
}
}
}
IntentService:
private void readActionData(){
Log.e("read actions data","data");
List<Action> actionList;
actionList = Action.listAll(Action.class);
Intent broadcastIntent = new Intent();
broadcastIntent.setAction(Utils.READ_ACTIONS_DATA);
broadcastIntent.putParcelableArrayListExtra(Utils.READ_ACTIONS_DATA, (ArrayList<? extends Parcelable>) actionList);
sendBroadcast(broadcastIntent);
}
ActionListActivity:
public class ActionListActivity extends BaseActivity {
boolean mIsReceiverRegistered = false;
DataBroadcastReceiver receiver;
TextView someTv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.action_list_activity);
this.initToolbarAndDrawerWithReadableName(getString(R.string.our_actions));
someTv = (TextView)findViewById(R.id.someTv);
}
public void someTvTest(Action action){
someTv.append(action.getName());
Log.e("data",action.getName());
}
#Override
protected void onPause() {
super.onPause();
if (mIsReceiverRegistered) {
unregisterReceiver(receiver);
receiver = null;
mIsReceiverRegistered = false;
}
}
#Override
protected void onResume() {
super.onResume();
if (!mIsReceiverRegistered) {
if (receiver == null)
receiver = new DataBroadcastReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(Utils.READ_ACTIONS_DATA);
receiver.setMainActivityHandler(this);
registerReceiver(receiver, filter);
mIsReceiverRegistered = true;
}
}
}
class DataBroadcastReceiver extends BroadcastReceiver{
ActionListActivity activity = null;
ArrayList<Action> list;
public void setMainActivityHandler(ActionListActivity main){
activity = main;
}
#Override
public void onReceive(Context context, Intent intent) {
Log.e("reciever","reciev");
list = intent.getParcelableArrayListExtra(Utils.READ_ACTIONS_DATA);
for (Action action:list){
if(activity!=null) {
activity.someTvTest(action);
}
}
}
}
You start activity and service async.
You need to start service inside ActionListActivity and wait for response.
I Have three activities
On activity A i register the broadcast receiver ,then i go to activity B from there i go to activity C.
and finally onBackPressed of activity c ,i send the broadcast
but onReceive is not called
My first Activity
private MyBroadCastReceiver myRecevier = new MyBroadCastReceiver();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Submit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent frag=new Intent(MainActivity.this,Activity2.class);
//frag.putExtra("Limit", foo);
startActivity(frag);
// }
}
});
}
#Override
protected void onResume() {
super.onResume();
//Register the activity to the broadcast receiver
registerReceiver(myRecevier, new IntentFilter(MyBroadCastReceiver.ACTION));
}
#Override
protected void onPause() {
super.onPause();
//Unregister the activity from the broadcast receiver. Good practice ;)
unregisterReceiver(myRecevier);
}
public class MyBroadCastReceiver extends BroadcastReceiver{
public static final String ACTION = "com.uberrueco.mybroadcastreceiver.receivers";
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MyBroadCastReceiver", "received");
Toast.makeText(context,"Received "+intent.getStringExtra("editText"), Toast.LENGTH_LONG).show();
}
}
}
Second activity has nothing but an intent to activity 3
Third Activity
public class Activity3 extends Activity {
EditText etReceivedBroadcast;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity3);
etReceivedBroadcast = (EditText) findViewById(R.id.etReceivedBroadcast);
}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
Intent intent = new Intent(this, MyIntentService.class);
intent.putExtra("editText", etReceivedBroadcast.getText().toString());
startService(intent);
}
}
and finally my IntentService class
public class MyIntentService extends IntentService{
public MyIntentService(){
super("MyIntentService");
}
public MyIntentService(String name) {
super(name);
}
#Override
protected void onHandleIntent(Intent intent) {
Log.d("MyIntentService", "handling intent...");
//Intent created for broadcasting
Intent intentBroadCast = new Intent();
//Filter the broadcast to the action desired
intentBroadCast.setAction(MyBroadCastReceiver.ACTION);
intentBroadCast.putExtra("editText", intent.getStringExtra("editText"));
//Send the broadcast :D
sendBroadcast(intentBroadCast);
}
}
You are calling unregisterReceiver in onPause of MainActivity . So you are not recieving the broadcast.
Move register to onCreate and unregister to onDestroy of your MainActivity.
if your onHandleIntent() was called then you should try like.
Intent intentBroadCast = new Intent(MyBroadCastReceiver.ACTION);
intentBroadCast.putExtra("editText", intent.getStringExtra("editText"));
//Send the broadcast :D
sendBroadcast(intentBroadCast);
make changes like below code
private MyBroadCastReceiver myRecevier = new MyBroadCastReceiver();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Register the activity to the broadcast receiver
this.registerReceiver(myRecevier, new IntentFilter(MyBroadCastReceiver.ACTION));
Submit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent frag=new Intent(MainActivity.this,Activity2.class);
//frag.putExtra("Limit", foo);
startActivity(frag);
// }
}
});
}
#Override
protected void onResume() {
super.onResume();
}
#Override
protected void onDestroy() {
super.onDestroy();
//Unregister the activity from the broadcast receiver. Good practice ;)
this.unregisterReceiver(myRecevier);
}
#Override
protected void onPause() {
super.onPause();
//Unregister the activity from the broadcast receiver. Good practice ;)
unregisterReceiver(myRecevier);
}
public class MyBroadCastReceiver extends BroadcastReceiver{
public static final String ACTION = "com.uberrueco.mybroadcastreceiver.receivers";
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MyBroadCastReceiver", "received");
Toast.makeText(context,"Received "+intent.getStringExtra("editText"), Toast.LENGTH_LONG).show();
}
}
}
u need to use like this this.unregisterReceiver() and this.registerReceiver()
Hi I developed one small android application in which I am using one activity one intent service and one broadcast receiver.
So my code looks like :
public class Main_Activity extends Activity {
private ResultReceiver resultReciver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_);
Log.i("***************************88", "inside activity on create");
IntentFilter filter = new IntentFilter("com.nilkash.broadcast.receiver");
resultReciver = new ResultReceiver();
registerReceiver(resultReciver, filter);
//LocalBroadcastManager.getInstance(this).registerReceiver(resultReciver, filter);
Intent intent = new Intent(this, ExampleService.class);
startService(intent);
}
public class ResultReceiver extends BroadcastReceiver{
public ResultReceiver()
{
}
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
Log.i("**********************", "inside broadcast receiver: ");
}
}
}
And intent service
public class ExampleService extends IntentService{
public ExampleService(String value)
{
super(value);
}
public ExampleService()
{
super("");
}
#Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
Log.i("********************************", "inside intetn reciver: ");
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("com.nilkash.broadcast.receiver");
//broadcastIntent.putExtra("value", "nilkash");
sendBroadcast(intent);
//LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}
}
In manifest file I define service.
So my problem is that I start service from activity and its working fine. From service on intent receive I sent one broadcast receiver but it not listening inside my broadcast receiver.
Am i doing some thing wrong? Need Help. Thank you.
There is an error: sendBroadcast(intent);. Should be another intent object (broadcastIntent).
I want to start a new activity in non-Activity class that implements a DialogListener following is my code:
public class FacebookLoginDialog implements DialogListener {
#Override
public void onComplete(Bundle values) {
HomeActivity.showInLog(values.toString());
Intent i1 = new Intent (this, SearchActivity.class);
startActivity(i1);
}
#Override
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
}
#Override
public void onError(DialogError e) {
// TODO Auto-generated method stub
}
#Override
public void onCancel() {
// TODO Auto-generated method stub
}
}
I can't start the new activity using intent in onComplete method, please help.
Thanks
This doesn't work because you need a Context in order to start a new activity. You can reorganize your class into something like this:
public class FacebookLoginDialog implements DialogListener {
private final Context context;
public FacebookLoginDialog(Context context) {
this.context = context;
}
#Override
public void onComplete(Bundle values) {
HomeActivity.showInLog(values.toString());
Intent i1 = new Intent (context, SearchActivity.class);
context.startActivity(i1);
}
//Other methods...
}
Then it will work.
Pass context as constructor parameter and then try this
Intent i = new Intent(this, SearchActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
use starActivity from non-activity class:
Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "YOUR STRING");
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Share via...");
context.startActivity(Intent.createChooser(intent, "Share"));
For Easy Usage you can a method for this particular method:
public class Something
{
public static void navigate(Context context, Class<?> nameOfClass)
{
Intent i = new Intent(context, nameOfClass);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
can be called in other class and method everytime by calling this:
Something.navigate(activityName.this, classYourWantTONavigateTo.class);
