How can you redirect to another activity once the application that was launched by createChooser such as show below is complete?
My attempt below ends up with the second intent being triggered before the createChooser launches. I noticed that when I press the back button on the newly launched activity is when the createChooser appears on the activity I wanted to launch it from.
I also tried to wrap the createChooser in startActivityForResult and then launch the second intent using onActivityResult but the result was the same
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
Intent trackIntent = new Intent(InformContacts.this, TrackOffers.class);
startActivity(trackIntent);
Here's the entire code:

//finish();
Log.i("Done sending email...", "");
}
else{
Toast.makeText(InformContacts.this, "No email app found. Email won't be sent.", Toast.LENGTH_SHORT).show();
}

if (resultCode == RESULT_OK){
if(requestCode == REQUEST_SEND_EMAIL){

startActivity(intent);
}
}
}
}
Try this
Change to:
if(requestCode == REQUEST_SEND_EMAIL){
Intent intent = new Intent(this, TrackOffers.class);
startActivity(intent);
}
Instead of:
if (resultCode == RESULT_OK){
if(requestCode == REQUEST_SEND_EMAIL){
Intent intent = new Intent(this, TrackOffers.class);
startActivity(intent);
}

I want to send images via email in my android app. For which I'm using Android Native Camera app and Intents to use the respective service. I've used the following code:
Email is getting send but if I'm trying to add image the app gets crash.
public class Complaints extends AppCompatActivity {

email.putExtra(Intent.EXTRA_SUBJECT, sub);
email.putExtra(Intent.EXTRA_TEXT, message);
email.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//this will make such that when user returns to your app, your app is displayed, instead of the email app.
email.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic));
email.setType("message/rfc822");

What you described was not so complete. But I this there are some reasons may result to this, then you can check it.
1. use super.onBackPressed() or give onBackPressed() return can make different
2. please check activity launch mode work.
but you'd better give a more detailed code,then I can help you
I'm analyzing this Voice Recognizer class and need help understanding this line in the code. What is the role of the following line? Does it create a list of all of the activities on the android platform loaded on the device? I especially find the resolve info bit confusing...
List activities = pm.queryIntentActivities(new Intent(
Here is the code used in context
package com.example.voicerecognitionactivity;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Spinner;
import android.widget.Toast;
public class VoiceRecognitionActivity extends Activity {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001;
private EditText metTextHint;
private ListView mlvTextMatches;
private Spinner msTextMatches;
private Button mbtSpeak;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
metTextHint = (EditText) findViewById(R.id.etTextHint);
mlvTextMatches = (ListView) findViewById(R.id.lvTextMatches);
msTextMatches = (Spinner) findViewById(R.id.sNoOfMatches);
mbtSpeak = (Button) findViewById(R.id.btSpeak);
}
public void checkVoiceRecognition() {
// Check if voice recognition is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
mbtSpeak.setEnabled(false);
Toast.makeText(this, "Voice recognizer not present",
Toast.LENGTH_SHORT).show();
}
}
public void speak(View view) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// Specify the calling package to identify your application
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass()
.getPackage().getName());
// Display an hint to the user about what he should say.
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, metTextHint.getText()
.toString());
// Given an hint to the recognizer about what the user is going to say
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
// If number of Matches is not selected then return show toast message
if (msTextMatches.getSelectedItemPosition() == AdapterView.INVALID_POSITION) {
Toast.makeText(this, "Please select No. of Matches from spinner",
Toast.LENGTH_SHORT).show();
return;
}
int noOfMatches = Integer.parseInt(msTextMatches.getSelectedItem()
.toString());
// Specify how many results you want to receive. The results will be
// sorted where the first result is the one with higher confidence.
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, noOfMatches);
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
//If Voice recognition is successful then it returns RESULT_OK
if(resultCode == RESULT_OK) {
ArrayList<String> textMatchList = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (!textMatchList.isEmpty()) {
// If first Match contains the 'search' word
// Then start web search.
if (textMatchList.get(0).contains("search")) {
String searchQuery = textMatchList.get(0).replace("search",
" ");
Intent search = new Intent(Intent.ACTION_WEB_SEARCH);
search.putExtra(SearchManager.QUERY, searchQuery);
startActivity(search);
} else {
// populate the Matches
mlvTextMatches
.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
textMatchList));
}
}
//Result code for various error.
}else if(resultCode == RecognizerIntent.RESULT_AUDIO_ERROR){
showToastMessage("Audio Error");
}else if(resultCode == RecognizerIntent.RESULT_CLIENT_ERROR){
showToastMessage("Client Error");
}else if(resultCode == RecognizerIntent.RESULT_NETWORK_ERROR){
showToastMessage("Network Error");
}else if(resultCode == RecognizerIntent.RESULT_NO_MATCH){
showToastMessage("No Match");
}else if(resultCode == RecognizerIntent.RESULT_SERVER_ERROR){
showToastMessage("Server Error");
}
super.onActivityResult(requestCode, resultCode, data);
}
void showToastMessage(String message){
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}
}
This, i think, is the simplest way of checking if voice recognition is present or not:
Intent intent = new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
try {
startActivityForResult(intent, RESULT_SPEECH);
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Opps! Your device doesn't support Speech to Text",
Toast.LENGTH_LONG);
t.show();
}
ANd after that:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_SPEECH: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
et_task_notes.setText(text.get(0));
}
break;
}
}
}
i have made an activity
at subscribe button, i have to send email to some default email for which my code is:

// i.putExtra(Intent.EXTRA_EMAIL , new String[]{"aman4251#gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");

} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(subscribeActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
});
}
}
which open an intent like this
now either i have to set the email id to "To" textbox (and make it uneditable"), or to automatically click on that "send" button so that user dont see this intent and email is send in back ground..
Try this code:
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_EMAIL , new String[]{"recipient#example.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT , "body of email");
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MyActivity.this, "There are no email clients installed.",Toast.LENGTH_SHORT).show();
}
Hi try this piece of code
Intent sendIntent = new Intent(Intent.ACTION_SEND);
// Add attributes to the intent
sendIntent.putExtra(Intent.EXTRA_EMAIL, "");
sendIntent.putExtra(Intent.EXTRA_CC, "");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "");
sendIntent.putExtra(Intent.EXTRA_TEXT, "");
sendIntent.setType("text/plain");
PackageManager pm = getPackageManager();
List<ResolveInfo> activityList = pm
.queryIntentActivities(sendIntent, 0);
Iterator<ResolveInfo> it = activityList.iterator();
boolean isEmailSetUp = false;
while (it.hasNext()) {
ResolveInfo info = it.next();
if ("com.android.email.activity.MessageCompose"
.equalsIgnoreCase(info.activityInfo.name)) {
isEmailSetUp = true;
sendIntent.setClassName(info.activityInfo.packageName,
info.activityInfo.name);
}
}
if (isEmailSetUp) {
startActivity(sendIntent);
} else {
AlertDialog.Builder dlgAlert = new AlertDialog.Builder(this);
dlgAlert.setMessage("No Mail Accounts");
dlgAlert.setTitle("Please set up a Mail account in order to send email");
dlgAlert.setPositiveButton(getResources().getString(R.string.ok),
null);
dlgAlert.setCancelable(true);
dlgAlert.create().show();
}
i dono know whether it is possible to make the email id edit text uneditable
But you can send mail in background by click on button
for that refer this link
Hi, I have integrated these codes such that I will be able to upload file rather than photo selected to AmazonS3, but for some parts, they are still part of uploading image suchs as "intent.setType("image/");"*

You could use this http://code.google.com/p/android-file-dialog/ activity and get the file selected by user.
