How to open Gmail Compose when a button is clicked in Android App?
I am trying to open up Gmail Compose screen when a button is clicked in my Android App. Do I need some API key for this from Google? or what do I need to do in my button onClickListener?
Any kind of insight is much appreciated.
Solution 1:
As JeffC pointed out, it is easy to essentially tell Android that you want to send something email-like and have Android give users a list of choices, which will probably include GMail. If you specifically want GMail, you have to be a bit cleverer. (Note that the correct MIME type is actually "text/plain", not "plain/text". Do to an implementation oddity, GMail seems to be the only activity which responds to the latter, but this isn't a behavior I would count on.)
The following App demonstrates the principle you can follow: actually examine all of the activities which say they can handle your SEND intent and see if any of them look like GMail.
package com.stackoverflow.beekeeper;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import java.util.List;
public class StackOverflowTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("text/plain");
final PackageManager pm = getPackageManager();
final List<ResolveInfo> matches = pm.queryIntentActivities(intent, 0);
ResolveInfo best = null;
for (final ResolveInfo info : matches)
if (info.activityInfo.packageName.endsWith(".gm") ||
info.activityInfo.name.toLowerCase().contains("gmail")) best = info;
if (best != null)
intent.setClassName(best.activityInfo.packageName, best.activityInfo.name);
startActivity(intent);
}
}
Solution 2:
try {
Intent intent = new Intent (Intent.ACTION_VIEW , Uri.parse("mailto:" + "your_email"));
intent.putExtra(Intent.EXTRA_SUBJECT, "your_subject");
intent.putExtra(Intent.EXTRA_TEXT, "your_text");
startActivity(intent);
} catch (ActivityNotFoundException e){
//TODO smth
}
Solution 3:
I don't know that you can specifically launch gmail. Have you tried this in your onClickListener
Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.setType("text/plain");
startActivity(emailIntent);
