There are previous discussions here regarding starting a Google Hangout from an intent on Android: start google hangouts in android
How can I start a Google Hangout
try in this way
Below method use to share text to hangout
/**
* Initiate the actions encoded in the specified URI.
*/
public void initiateHangOutUri(Context myContext, String textToShare) {
// Make sure Android client is installed.
if (!isHangOutClientInstalled(myContext)) {
goToMarket(myContext);
return;
}
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, textToShare);
sendIntent.setType("text/plain");
sendIntent.setPackage("com.google.android.talk");

Below method use to check HangOut installed on this device
/**

**/
public boolean isHangOutClientInstalled(Context myContext) {
final PackageManager packageManager = context.getPackageManager();
Intent intent = packageManager.getLaunchIntentForPackage("com.google.android.talk");
if (intent == null) {
return false;
