send a image from gallery in email service in android

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 {
Button sendEmail;
EditText to, subject, msg;
Bitmap image;
Button camera;
File pic;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_complaints);
to = (EditText) findViewById(R.id.et1);
subject = (EditText) findViewById(R.id.et2);
msg = (EditText) findViewById(R.id.et3);
sendEmail = (Button) findViewById(R.id.s_Email);
camera = (Button) findViewById(R.id.btn_img);
camera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent=new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(Intent.createChooser(intent,"Select Picture"));
}
});
sendEmail.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String Emailid = to.getText().toString();
String sub = subject.getText().toString();
String message = msg.getText().toString();
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[]{Emailid});
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");
email.setType("image/jpeg");
try {
startActivity(Intent.createChooser(email, "Message was Sent"));
}
catch (ActivityNotFoundException e) {
Toast t = Toast.makeText(Complaints.this, "There is No Emial Client installed ", Toast.LENGTH_SHORT);
t.setGravity(Gravity.CENTER, 0, 10);
t.show();
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 10) {
image = (Bitmap) data.getExtras().get("Data");
ImageView i = (ImageView) findViewById(R.id.img);
i.setImageBitmap(image);
try
{
File root= Environment.getExternalStorageDirectory();
if(root.canWrite())
{
pic=new File(root,"pic.jpeg");
FileOutputStream out=new FileOutputStream(pic);
image.compress(Bitmap.CompressFormat.JPEG,100,out);
out.flush();
out.close();
}
} catch (IOException e)
{
Log.e("BROKEN", "Could not write file " + e.getMessage());
}
}
}

startActivityForResult(Intent.createChooser(send_report, "Choose an Email client"), 77);

Android pdf view redirect

I have the following code that pulls a pdf document from a remote viewer to view:
package com.example.techvault;
import java.io.File;
import java.io.IOException;
import java.util.List;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
public class PDFFromServerActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_document);
Intent in= getIntent(); // gets the previously created intent
String url = in.getStringExtra("full_url");
if (!url.startsWith("http://") && !url.startsWith("https://")){
url = "http://ezdrawdocs.com" + url;
}
Log.d("pdf url: ",url);
String extStorageDirectory = Environment.getExternalStorageDirectory()
.toString();
File folder = new File(extStorageDirectory, "pdf");
folder.mkdir();
File file = new File(folder, "Read.pdf");
try {
file.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
Downloader.DownloadFile(url, file);
showPdf();
}
public void showPdf()
{
File file = new File(Environment.getExternalStorageDirectory()+"/pdf/Read.pdf");
PackageManager packageManager = getPackageManager();
Intent testIntent = new Intent(Intent.ACTION_VIEW);
testIntent.setType("application/pdf");
List list = packageManager.queryIntentActivities(testIntent, PackageManager.MATCH_DEFAULT_ONLY);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "application/pdf");
startActivity(intent);
}
}
When the backarrow is selected it redirects to a blank screen. How can I control which activity to redirect to when backarrow is selected?
Thanks

You can define that in your manifest under the activity with
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.yourapp.SomeActivity" />

What you're doing here is implementing what I call a "Passthrough Activity" (an Activity that has no UI and immediately launches a different Activity)... I personally try to avoid them.
That said, what you need to do is call Activity.finish() after showPDF() in Activity.onCreate(). That will close your passthrough so that when you back out of the PDF viewer you will not come back to the passthrough.

how to set text on "to" textarea in email activity

i have made an activity
at subscribe button, i have to send email to some default email for which my code is:
package sditm.app;
import android.R.string;
import android.app.Activity;
import android.content.ContentValues;
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.text.Html;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class subscribeActivity extends Activity {
/** Called when the activity is first created. */
EditText name,age,address;
databaseforsubscribe addressBook;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.subscribe);
Button store = (Button)findViewById(R.id.button1);
name=(EditText)findViewById(R.id.editText1);
age=(EditText)findViewById(R.id.editText2);
address=(EditText)findViewById(R.id.editText3);
addressBook = new databaseforsubscribe(this,"addressDB",null,2);
store.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
String s=new String();
String m=new String();
String n=new String();
s=name.getText().toString();
m=age.getText().toString();
n=address.getText().toString();
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_EMAIL, "aman4251#gmail.com");
// i.putExtra(Intent.EXTRA_EMAIL , new String[]{"aman4251#gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT ,"NAME: "+s+" ; MOBILE: "+m+" ; EMAIL: "+n);
try {
startActivity(Intent.createChooser(i, "Send mail..."));
} 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

Reading a PDF file from Android

I am trying reading a Pdf file from android app.
It builds an app and there is no error, but when I click the button it doesn't do anything. it looks like the app thinks there is no file.
I need a help because i am quite new to android apps but need to finish this job today or tomorrow. The person doing this is away at the moment.
package com.readPDF;
import java.io.File;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class ReadPDF extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.pdfbutton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "in.", Toast.LENGTH_LONG).show();
File file = new File("http://path/pathtopdf/mypdf.pdf");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
Toast.makeText(ReadPDF.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
}
}
private Context getContext() {
// TODO Auto-generated method stub
return null;
}
});
}
}

your pdf path is incorrect. change other valid path and then try again. then first try whether you set internet permission.

You can't directly fetch a file in a remote server using new File("http url").
URI uri = new URI("http", "//path/pathtopdf/mypdf.pdf", null);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(ReadPDF.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
